With a collaborator, I built a model that predicts lung-cancer stage from three CT scans taken over time. At NIST, I wrote Python code that finds individual droplets in a light sensor’s signal. With a partner, I made SAFEY, safety software that opens as a calculator. I also research robot swarms, run a tutoring club, led a build of sensory boards for memory-care residents, and teach guitar.

Lung Cancer Research

Lung-cancer screening gives a person a series of CT scans taken over time, but a model that reads one scan sees only a single moment. With a collaborator, I tested whether a model that uses the changes across three scans can predict how far a lung cancer has spread better than a model that sees only one.

NIST NCNR Droplet Analysis

Droplets flow through a thin tube, separated by oil, and a light sensor records them as one continuous line. I wrote code that finds where each droplet starts and ends in that line. A separate image-analysis program measures droplet length and speed; I moved it from MATLAB to Python, and found the two versions gave different numbers for the same data.

SAFEY

An app for people experiencing domestic violence: a risk check, a safety plan and a list of resources. It opens disguised as an everyday app, such as a calculator or a notes app, because opening a safety app where another person can see it can be unsafe for someone in danger.

The app behind it

From our demo video, slightly sped up: the disguise (here a notes app) unlocking with a PIN, and the risk check, safety plan and emergency screen behind it.

Portable Sensory Boards

Four boards for memory-care residents at Dulles Health & Rehab Center, covered in latches, switches, zippers, beads and fur to touch and work. A staff member can pick one up and carry it to a resident’s room.
