Earlier Work

I started research in high school, where I'm extremely grateful to my mentors for inspiring an enduring love for research. I worked on a smattering of projects, but most notably ML for the environment and ML in biomedical engineering, specifically work on mangrove ecosystem recovery using satellite remote sensing (AGU 2022) and microarray-format digital ELISA biosensor development (Biosensors and Bioelectronics, 2023).
