About Me

Hi there! I am a Biostatistician and Sessional Instructor at UBC. Recently, I completed my Master’s in Statistics at UBC where I was supervised by Dr. Gabriela V. Cohen Freue. My Master’s thesis is titled Robust sparse covariance-regularized regression for high-dimensional data with Casewise and Cellwise outliers.

Industry Experience

Before starting my Master’s, I took a role at Stripe as a software engineer. I worked on the Risk Tooling team, where I built tools that help risk analysts detect fraud. I worked in languages like Ruby and ReactJS to build data pipelines, backends, and user-friendly interfaces for processing and displaying sensitive financial data.

During my time at Waterloo, I also completed 6 internships in the technology sector with focuses ranging from application development to machine learning. My last internship was at Bloomberg (News AI), where I worked on NLP models for predicting news persistence based on textual and quantitative features. I was also an intern at Stripe, where I worked on object detection models and text extraction on the Identity team.

For Fun

Outside of statistics, you might find me climbing, snowboarding, playing piano, or drawing. You can find some of my art here. I dabble in digital drawing but also enjoy colored pencils and ink media.
