## About Me



I am a PhD Candidate in Biology at Pennsylvania State University, where I build mathematical models of infectious diseases as part of Dr. Matt Ferrari’s lab (within the Center for Infectious Disease Dynamics), in addition to other infectious disease epidemiology work.
I previously worked as a clinical research coordinator in the Infectious Disease Division at the Hospital for Sick Children (Toronto, Canada), and concurrently completed an MSc in Global Health Policy at LSHTM.
Whilst completing my Masters in computational chemistry, I realized that I enjoyed research and computational modeling, but wanted to work in a more applied healthcare-related field.
Since then, I have applied and developed my skills in Public Health research.

My research interests are in infectious disease epidemiology, with a particular focus on the use of mathematical models to improve outbreak response and resource utilization: namely, how the choices we make in categorizing continuous quantitative data affects our understanding and ability to anticipate, detect, and respond to outbreaks.
I primarily work with [R](https://www.r-project.org/) and [Julia](https://julialang.org/), but have experience with [Python](https://www.python.org/), Bash, and am learning [Rust](https://www.rust-lang.org/) for fun

When I'm not working, I can be found outside doing one of the following (depending on the season): mountain biking, road cycling, rock climbing, hiking, snowboarding, cross-country skiing, or very occasionally, running.
