I’d spent two months researching rural hospital closures for UChicago’s Research in the Biological Sciences program, building what I thought was an airtight case for Medicaid expansion. She raised her hand halfway through my conclusion. “Your selection bias problem is severe,” she said. “And these confounding variables,” she added, gesturing at my chart, “you’re not accounting for them at all.”

My face burned. The forum moderator mercifully called for a break.

She found me afterward in the hallway, pulling out a napkin and sketching regression models in blue pen. “Here’s what instrumental variables do,” she said, drawing arrows between boxes. “They let you isolate causal effects when randomization isn’t possible.” For an hour, this UChicago PhD treated my mangled research like it deserved rigorous repair. She showed me how to rebuild my argument properly, pointing out which data I’d need, which assumptions I could test, where I’d actually stumbled onto something worth pursuing.

I left that conversation electrified. This was the education I wanted: people who cared enough about ideas to tell you exactly where you’d gone wrong, who treated intellectual honesty as the highest form of respect.

UChicago’s Core promises exactly this kind of rigor. I picture myself in a “Classics of Social and Political Thought” seminar, watching someone defend Hobbes while another student systematically dismantles their reading of Leviathan, the professor occasionally interjecting, “But what does the text actually say?” I want to read The Wealth of Nations the same week I’m reading Marx, letting them argue with each other across centuries in my head. I’m drawn to “Self, Culture, and Society” specifically because examining my assumptions about rural community and individualism feels urgent. I’ve spent years living these tensions without the vocabulary to articulate them properly.

The economics major’s theoretical foundation appeals to me because I’ve seen what happens when policy gets built on shaky statistical reasoning. I want Professor List’s course on field experiments, learning how to design studies that actually isolate causal mechanisms. I want to understand why difference-in-differences estimators work, not just how to run them in Stata. My county doesn’t need another policy brief from someone who’s memorized techniques without understanding their breaking points.

The Energy & Environment Lab’s rural climate work feels like it’s addressing my backyard. Professor Greenstone’s research quantifying pollution costs in precise economic terms—childhood asthma rates, lost wages, medical expenditures—transforms what’s usually pure rhetoric into answerable questions. I want to learn how to build arguments that survive expert review, because the policies that actually pass are the ones grounded in evidence nobody can dismiss.

But I’m equally excited about UChicago’s intellectual restlessness. I’m interested in the HUMA12300: “Human Being and Citizen” course because thinking rigorously about justice and capability seems foundational to any policy work worth doing. I want to argue about democratic theory at a Society of Fellows dinner, attend Institute of Politics debates, write op-eds for The Maroon that get thoroughly rebutted the next week by someone with better evidence.

I’m hunting for the kind of friends who’ll say “prove it” when I make sweeping claims about agricultural subsidies, who consider “I hadn’t thought about it that way” a compliment rather than a concession, who care enough about getting things right to tell me when I’m wrong.

That napkin-sketch conversation last summer showed me what four years at UChicago could look like: constantly rebuilding arguments, discovering better questions, learning that intellectual humility and intellectual ambition aren’t contradictory but complementary. The economist who questioned my presentation did me a favor. She showed me exactly what I’d been looking for. (599 words)

That was the first time I understood that thoughts could starve.

Alzheimer’s arrived in my grandfather’s life in the thirty-second pause before he remembered my name, in the moment he put his reading glasses in the refrigerator and accused my mother of hiding them. He’d been a calculus teacher for thirty-one years. He could do mental math faster than anyone I knew, and then he couldn’t remember how a fork worked.

In sophomore biology, I learned that the brain burns through roughly twenty percent of the body’s total energy. Neurons communicate through electrochemical signals that depend on glucose, oxygen, a precise cocktail of neurotransmitters synthesized from the food we chew and the air we breathe. Thoughts eat constantly. They are, biologically, among the most expensive things the human body does.

But Alzheimer’s doesn’t starve thoughts by cutting off fuel. Instead, the disease starves them by destroying the kitchen. Beta-amyloid plaques accumulate between neurons, and Tau proteins tangle inside them. Synapses, the connections where thoughts actually happen, wither. The brain keeps burning energy, but the infrastructure that turns it into memory, recognition, language, all of it collapses from the inside.

The summer before junior year, I was accepted into the Stanford Institutes of Medicine Summer Research Program, where I spent eight weeks studying neurodegeneration under Dr. Lena Marsh. Our cohort examined post-mortem hippocampal tissue from donors who had lived with Alzheimer’s. Under the microscope, the damage looked like a city after an earthquake, structures half-standing, connections severed mid-span. I remember staring at a slide of a seventy-eight-year-old woman’s temporal lobe and thinking about my grandfather at the kitchen table, trying to remember which drawer the forks belonged in.

One afternoon, Dr. Marsh said something that reframed everything. Most Alzheimer’s research focuses on molecular mechanics, like the plaques, the tangles, the genetic risk factors. Very little funding goes toward the lived experience of patients and their caregivers. “We know a lot about how the brain breaks down,” she said. “We know almost nothing about how to help people live while it does.”

That sentence split my ambition in two. I still want to understand the cellular machinery of memory and its collapse, but I also want to work on the human half.

My grandfather spent his last three years in a memory care facility that cost my family six thousand dollars a month and still couldn’t keep him from wandering into the parking lot in his pajamas. The staff was kind but overwhelmed, undertrained, stretched across too many patients. This is the reality for millions of elderly Americans with neurological conditions, and it is a policy failure as much as a medical one.

UChicago is one of the few places where I could hold both halves of this problem at once. The neuroscience major would ground me in the biology of neurodegeneration, while the Harris School would let me study the systems that determine how we care for people once the diagnosis comes. Professor John Bhatt’s research on aging and cognitive decline sits at exactly that intersection, and the Core Curriculum’s insistence on foundational questions across disciplines mirrors how I’ve come to think about Alzheimer’s: as a question that belongs to science and ethics simultaneously.

Thoughts eat through glucose and oxygen and synaptic transmission, but they also eat through dignity, through environments that orient rather than confuse, caregivers paid enough to stay, facilities designed around the patient’s remaining cognition. My grandfather’s fork question haunts me because it captures both dimensions: a neuron failing to fire, and a man losing his place at his own table.

I want to study how thoughts eat so I can help build a world where aging minds are nourished cellularly, structurally, and humanely, for as long as they’re still hungry. (691 words)

My grandmother wove. She’d done it since girlhood in Appalachia, learning from her mother, who’d learned from hers. She had a four-harness floor loom in her back room that took up more space than her bed. I grew up crawling under it, pulling loose threads from the treadles, watching her pass the shuttle back and forth for hours.

When I asked her once why she didn’t just buy blankets, she held up a single cotton thread and snapped it between her fingers. Then she handed me a swatch she’d finished that week and told me to try tearing it. I couldn’t.

“That’s warp and weft,” she said. “Ordinary thread, extraordinary structure.”

I didn’t think about that sentence again until AP Physics, when Mr. Hernandez introduced tensile strength and load distribution. He was explaining why bridges use trusses, how geometric arrangement lets weak materials bear enormous weight, and I thought about my grandmother’s loom. Warp and weft operate on the same principle. Each individual thread is fragile, but when interlocked at perpendicular angles under tension, the resulting fabric distributes force across its entire surface. The strength isn’t in the material but in the architecture of connection.

That principle already appears in aerospace engineering. Carbon fiber-reinforced polymers are essentially woven composites, sheets of carbon filament interlaced in precise patterns and set in resin, stronger than steel at a fraction of the weight. The James Webb telescope’s sunshield is made of layered Kapton films whose deployment depends on the same geometric logic my grandmother used every afternoon: controlled folding, sequential tensioning, structure emerging from sequence.

Coastal communities like mine face a compounding crisis: hurricanes are intensifying, building costs are rising, and conventional construction, like plywood sheathing, oriented strand board, and standard framing, fails catastrophically under high wind loads. What if we applied woven composite principles to residential building panels? Not carbon fiber, which is prohibitively expensive, but locally sourced natural fibers like flax, hemp, and jute, interlaced in engineered warp-and-weft configurations and bonded with bio-based resins.

Research out of the University of Bath and the Fraunhofer Institute has already shown that natural fiber composites can approach the specific strength of fiberglass at significantly lower cost and environmental impact. The missing step is translating laboratory prototypes into standardized building components affordable enough for the communities that need them most.

I’ve spent the last year prototyping small-scale versions in my school’s makerspace, weaving jute cord into flat panels and testing their flex resistance against plywood samples of comparable thickness. The jute panels flex further before breaking, absorbing impact rather than shattering. They behave, structurally, the way my grandmother always said good cloth should: they give without giving way.

UChicago is where I want to take this from a makerspace experiment to something real. The Pritzker School of Molecular Engineering approaches materials at the level where structure determines function, exactly the scale where woven composites succeed or fail. Professor Stuart Rowan’s work on adaptive and sustainable polymers aligns with the bio-based resin systems these panels would need, and the university’s partnership with Argonne National Laboratory would give me access to characterization tools that could help me understand why my jute panels flex instead of fracture.

UChicago’s interdisciplinary rigor also means I’d be asking the deeper question my grandmother answered instinctively every time she sat at her loom: why does connection make ordinary things strong? The thread is ordinary, but the structure is extraordinary. And the people who understood this first were weavers. (670 words)

My mother said this at dinner when I was fifteen, trying to explain why my grandfather in Guadalajara refused to use WhatsApp. She meant you can’t teach an old dog new tricks. She also meant you can’t lead a horse to water. What came out was something neither English nor Spanish had ever produced on its own: an image of an aging dog standing at the edge of a strange river, unsure whether to drink.

I wrote it down. I’d been writing down my family’s English mistakes since middle school, not to mock them but because they kept accidentally making poetry.

We moved from Puebla to Milwaukee when I was nine. My English came in slowly and on top of my Spanish. I mixed tenses and borrowed syntax from one language to fill gaps in the other. My fourth-grade teacher corrected me gently and constantly. I learned the rules, but the mixing never fully stopped, and somewhere around eighth grade, when I started reading poetry seriously, I realized I didn’t want it to.

A mixed metaphor is supposed to be an error. You’re told to avoid them in essays, speeches, and formal writing, but a metaphor is already a collision, a mapping of one thing onto another to generate meaning that neither thing carries alone. When you mix metaphors, you’re colliding collisions. You’re forcing two borrowed worlds to share a sentence and seeing what survives.

My mother’s old dog standing at new water works because it captures something neither original metaphor captures by itself. “Can’t teach an old dog new tricks” is about stubbornness. “You can lead a horse to water but you can’t make it drink” is about autonomy. The mix produces a third meaning: the bewilderment of encountering something unfamiliar late in life and not knowing whether the problem is ability or willingness.

When I read Federico García Lorca in translation, I kept thinking about what survives between languages and what mutates. Lorca’s “duende,” that untranslatable Spanish concept of dark, earthy artistic power, becomes flattened in English to “passion” or “spirit.” The translation is technically correct but spiritually wrong. What if the gap between the two versions isn’t loss? What if it’s a mixed metaphor, a space where two incomplete meanings overlap and create a third thing that belongs to neither language?

This is how I’ve come to understand my own writing. My poems sit in the overlap between Spanish and English. When I write “the moon has teeth tonight,” I’m thinking of the Spanish “luna” and the way my mother used to say “la luna muerde” (“the moon bites”) when the crescent was sharp. In English, moons don’t bite. In my poems, they do.

I’ve published three poems in The Adroit Journal, all of them rooted in this bilingual friction. My English teacher called them “disorienting in a good way.” I think that’s the best definition of a mixed metaphor I’ve heard.

UChicago is where I want to study this friction seriously. The Creative Writing program would give me the craft training to control what I’m doing with language, while the Linguistics department, especially the work on contact linguistics and code-switching, would help me understand why bilingual minds produce the kinds of collisions they do. I’m drawn to UChicago’s Core because it asks you to take ideas apart at their foundations, and I want to take apart the assumption that mixing is always wrong. Sometimes two wrong metaphors make a right.

My mother never finished learning English. She speaks it imperfectly, inventively, with structures borrowed from a world the listener can’t see, exactly the way I write poems. She doesn’t know she’s been making poetry at the dinner table for six years. Every time she opens her mouth in her second language, however, she is doing what every metaphor does: carrying meaning across a gap, and changing it in the crossing.

You can’t teach an old dog new water. But you can watch him stand at the river’s edge and wonder. (672 words)

I propose a new Olympic event: Competitive Waiting.

Here’s how it works. Thirty-two athletes enter a regulation waiting room equipped with plastic chairs, a number dispenser, a counter that advances at deliberately irregular intervals, and a wall-mounted television playing daytime programming at a volume slightly too low to follow. Each athlete takes a number, and the number system bears no logical relationship to their arrival order. There is no estimated wait time.

Athletes are scored across four dimensions. First, composure: measured via heart rate monitors and microexpression cameras, tracking physiological calm despite uncertainty. Second, stillness: scored by motion sensors embedded in the chairs, with deductions for fidgeting, sighing audibly, or checking the counter more than twice per minute. Third, resilience: at random intervals, an official announces that the system is experiencing delays and all numbers will be reissued, and athletes must accept this without visible distress. Finally, Grace Under Bureaucracy: each athlete must complete, while waiting, a six-page form that requests the same information in three different formats, and they are judged on accuracy, penmanship, and the absence of exasperated marginal notes.

Officials are drawn from retired DMV employees. They are selected for their ability to maintain a neutral expression while delivering unhelpful information. Judges sit behind a one-way mirror.

I’m joking, but only partly.

My family immigrated from Karachi when I was five. By the time I was twelve, I had logged more hours in government waiting rooms than most people log at the gym. Visa renewals, work permits, green card interviews, Social Security offices, public health clinics. Waiting was the constant. My mother brought crossword puzzles, and my father brought patience I didn’t understand until I was older: the patience of a man who knew that frustration was a luxury available only to people whose paperwork wasn’t under review.

In Willpower: Rediscovering the Greatest Human Strength by Roy Baumeister and John Tierney, I learned about a concept called “ego depletion,” the theory that self-control draws from a finite cognitive resource that gets exhausted over time. Waiting in uncertainty is one of the most depleting activities the human brain can perform, because it demands sustained attention without a clear endpoint. Your prefrontal cortex stays activated, burning energy, managing impulses, suppressing the urge to stand up and ask, for the third time, whether your number is close. It’s endurance work. It just doesn’t look like it.

That’s why I think Competitive Waiting belongs in the Olympics. The Games celebrate the visible body, like the sprinter’s legs, the swimmer’s shoulders, the gymnast’s controlled flight, but they overlook the invisible athleticism of restraint, composure, and cognitive endurance under conditions designed to erode all three. Waiting is an act of sustained self-regulation, and billions of people perform it daily in hospitals, courtrooms, border crossings, and housing offices with no recognition that what they’re doing is hard.

At UChicago, I want to study the intersection of behavioral psychology and public policy: how the systems we build either respect or exhaust the people who move through them. The Crown Family School of Social Work’s focus on evidence-based policy aligns with a question I’ve been asking since that plastic chair in Queens: why do we design systems that punish the people who need them most? Professor Sendhil Mullainathan’s work on scarcity and cognitive load gave language to what my parents lived: that poverty and bureaucratic friction not only waste time but also consume the very mental resources people need to escape them.

My mother still brings crossword puzzles to the immigration office. She’s been a citizen for six years, but she goes with neighbors who aren’t. She sits with them, fills out their forms, tells them to breathe.

She’d take gold. (694 words)

I spent the rest of that summer studying stems, not because anyone told me to, but because I wanted to understand the infrastructure of a living thing.

Four years later, in seventh grade, my school held an assembly about “getting students excited about STEM.” I leaned forward in my seat. Then a man from a software company started talking about coding.

I have been living inside this confusion ever since.

Every time someone says STEM, I think about xylem and phloem, the vascular tissues inside a plant stem that transport water and sugar in opposite directions simultaneously, a logistics system more elegant than anything I’ve seen diagrammed in an engineering class. Every time a guidance counselor encourages me to “pursue STEM,” I want to say I already am. I’ve been pursuing stems since I was eight years old, on my knees in red Georgia clay, learning why one plant thrives and another collapses.

The irony, of course, is that botany is a STEM discipline. My love of actual stems is, taxonomically, a love of STEM. But the acronym has drifted so far toward coding and robotics and app development that the living sciences sometimes feel like tenants in their own house. When my school launched a STEM lab, it got 3D printers and soldering stations. It did not get a greenhouse.

I built one anyway. Junior year, I proposed converting an unused storage area behind the biology wing into a small-scale growing space for plant science experiments. The administration said yes, mostly because I presented a cost analysis showing it would run on less than the 3D printer’s annual filament budget. I now manage twelve raised beds where students in AP Biology and AP Environmental Science run controlled experiments on soil nitrogen content, on photoperiod manipulation, on companion planting.

Last semester, I used the greenhouse to test whether mycorrhizal fungi networks allow tomato plants to share chemical stress signals. I presented my findings at the Regeneron International Science and Engineering Fair in Los Angeles, where I placed third in Plant Sciences.

This is the work I want to continue at UChicago. The biological sciences program treats ecology and molecular biology with equal seriousness, and I’m drawn to the research happening at the Chicago Botanic Garden through UChicago’s partnership, particularly Dr. Jeremie Fant’s work on plant conservation genetics.

The Core Curriculum appeals to me because the question I keep asking is about how we decide which knowledge counts. Why did STEM come to mean silicon instead of cellulose? That’s a question about culture, funding, priorities, and the stories we tell about what innovation looks like. UChicago is one of the few places where I could investigate plant science and the sociology of its erasure in the same undergraduate career.

My mother still gardens. She’s sixty-one and her backyard plot has expanded to thirty varieties across four raised beds and a trellis system she designed herself out of PVC pipe. She has never once called what she does STEM. She simply calls it paying attention.

That’s what I’ve learned from stems, lowercase. A plant stem doesn’t announce its importance. It just moves water upward against gravity, distributes sugars to every growing tip, holds the whole organism upright, and does it so subtly that most people look past it to the flower. The acronym STEM could learn something from the structure it’s named after.

I don’t want to choose between the two meanings. I want to study in a place that understands they were never separate to begin with. (682 words)

Every seven years, your body replaces nearly every cell. The atoms that made you at seven aren’t the atoms making you at fourteen. You’re a Ship of Theseus, rebuilt continuously, molecule by molecule, without anyone noticing the planks being swapped out.

I learned this in AP Biology the same week my therapist told me I wasn’t the same person I’d been before treatment. We were studying cellular turnover, how skin cells regenerate every two weeks, red blood cells every four months, bones every decade. I sat in class taking notes about apoptosis and cellular regeneration while my brain tried to process what my therapist had said: “The neural pathways that created those thought patterns two years ago don’t exist anymore. You’ve literally rewired your brain.”

For two years, I’d lived with depression that felt molecular, something broken at the chemical level. Neurotransmitters misfiring, serotonin receptors giving my neurons the wrong instructions. Therapy and medication slowly rebuilt the machinery. CBT created new neural pathways while SSRIs adjusted receptor sensitivity, teaching my brain a different chemical language.

I kept the same name, the same face, lived in the same house, sat at the same desk doing homework. But underneath, the infrastructure had been completely reconstructed.

The Ship of Theseus paradox asks: if you replace every plank, is it still the same ship? My therapist said yes: continuous identity persists through transformation, like a river that’s never the same water but always the same river. My biology textbook implied no: if every component changes, what remains except the idea of a ship?

I couldn’t answer. I just knew I felt like evidence for both positions simultaneously, like I was living proof that the paradox couldn’t be resolved because both answers were true.

The girl who couldn’t get out of bed for three months is gone. Every neuron that fired those catastrophic thoughts has been replaced through natural turnover or rewired through neuroplasticity. The pathways that convinced me I was worthless have been pruned, new connections formed through repeated therapeutic intervention. Even my gut microbiome—which influences serotonin production—has changed completely through diet modifications my nutritionist recommended.

Molecularly, I’m different. And yet I remember being her with perfect clarity. I carry scars she created. I make decisions informed by what she survived.

This is what draws me to UChicago’s Molecular Engineering program: this exact question of how transformations at the cellular level relate to continuity at the systems level. When you rebuild something component by component, what persists? Scientists can now grow organs from stem cells, engineer tissue plank by plank. Is a lab-grown heart the same as the original? It has identical molecular structure, performs identical functions, but it was built in a petri dish rather than a womb. Does origin matter, or only composition and capability?

My depression treatment worked similarly. Therapy didn’t repair the malfunctioning neural pathways; it built new ones alongside them, creating alternate routes while the damaged circuitry remained, like constructing fresh planks while the rotting ones stay embedded in the hull, bypassed but still present.

I recognized the transformation not through dramatic change but through the accumulation of small differences I didn’t notice until they added up to something fundamental. One morning, I woke up and realized I’d stopped performing the calculation: the constant background assessment of whether today was worth continuing, whether existing required more energy than I had available. I hadn’t noticed it leaving, only its absence, the way you don’t notice silence until you realize the noise has stopped.

That’s when I understood: identity might live in the pattern, not the material. My neurons are different, but they fire in patterns that remember who I was, incorporate what I’ve learned, create who I’m becoming. The ship is the shape the planks make together, not the planks themselves. I am the Ship of Theseus. Rebuilt, plank by plank, neuron by neuron. Still me. Completely different. Sailing. (693 words)
