Previous Work

Visual processing

My first lab rotation was in August 2023, in Dan Denman's lab in the Department of Neuroscience. Over the 5 weeks, I used a Neuropixels platform developed by the Denman lab to obtain high-density recordings from multiple areas implicated in visual processing in awake mice to investigate dynamics of communication between these populations.

Spinal Circuits and Plasticity

I was a postbaccalaureate fellow in Ariel Levine's lab at the National Institutes of Health. I am particularly interested in understanding how the spinal cord contributes to the control of movement. I contributed to numerous projects, including a review of genetic tools for studying the cellular basis of behavior, an atlas of single cell data of the mouse spinal cord after injury, and a cellular taxonomy of the adult human spinal cord (in press).

Spinal Cord Injury

As an undergraduate student in Steve Perlmutter's lab, I contributed to work in spinal cord injury and rehabilitation in rat models.

My undergraduate honors thesis on the changes in gene expression in rat spinal cords with therapy can be read here.

My code for training networks to track rats on a horizontal ladder and use heuristics to score the behavior is located here. My additional work to train a supervised training algorithm to quantify the behavior is located in this repo.

Circadian Rhythms of Students

As a high school student, I worked in Horacio de la Iglesia's lab to investigate the intersection of sleep and circadian rhythms in humans, particularly students. I continued to contribute to the project which you can read about in this paper.

Some of this code I wrote back then to process the actimetry data is publically available here. More recently, I've contributed to additional analysis of these data and the code for producing the clock plots for a poster is available here.
