A field sensor project leads the writer toward engineering that connects measurement, infrastructure, and public interpretation.
My first air-quality sensor succeeded on a desk and failed at a bus stop. Condensation clouded its housing, trucks distorted readings, and the battery died before evening commuters arrived. Rebuilding it taught me that measurement is never only electronics. It includes weather, placement, maintenance, and the public question a number is supposed to answer. A daily average, for example, hid the short pollution peaks parents noticed during school pickup.
In Cornell Engineering, I would pursue that full chain through environmental systems coursework, project teams, and undergraduate research that treats field conditions as part of design. I want to strengthen my understanding of fluid flow and sensor calibration, then test inexpensive instruments against reference equipment. Cornell's project-based culture also matters because housings, power systems, interfaces, and community use cannot be solved in separate notebooks. I would verify specific courses and research openings each term rather than assuming access from a program name.
I would bring experience documenting low-cost repairs and translating graphs for our transit coalition. More importantly, I would bring the habit my failed prototype produced: ask who will maintain the device, which uncertainty must remain visible, and what decision the display enables. I am drawn to Cornell because engineering there can move between fundamentals, field testing, and consequences beyond the laboratory. My goal is not simply a more accurate sensor. It is a measurement system durable and understandable enough that communities can challenge what is measured and use the evidence in consequential public decisions that affect their routes home.
