Hello, this website displays my technical background highlighting Projects, Education, and Experience relevant to computer science. Please take a look around and use the contact form below for any inquiries.
​
I am currently finishing my Master's Degree in Computer Science with a concentration in Artificial Intelligence.
​
I work with Professor Alex Pang and the AVIS lab to develop Computer Vision research for community-driven applications. The software running in the section below shows an application we created to detect rip currents using drones.
Research Interests
This video playing on the right is a recording from a pilot application developed in part for my research "Realtime ML-Assisted Data Collection using Drones" with the AVIS lab. Clicking the title in the previous sentence will provide a more detailed explanation of the research. To capture this video I put a lightweight Machine Learning model on a cell phone that connects to the drone's camera. I then flew a drone over several beaches in Santa Cruz. Once the ML detects a rip current, a recording automatically starts for 30 seconds (hence the timer in the center). The resulting video gets saved on the phone.
Currently, I am assisting the city of Santa Cruz to install this software in the Walton Lighthouse to aid lifeguards in keeping swimmers safe.

Note: "Back" and "Stop ML" are features of the app that won't work in this video.
