Control Theory Applied to Invasive Species

To formulate management strategies for dealing with invasive species I use techniques from control theory, including optimal and adaptive control.

Deterministic and Stochastic Models for Epidemiology

When developing models for a variety of infectious diseases, I utilize deterministic and stochastic dynamics along with heterogeneous populations. 

Variety of Mathematical Models and Applications

Additionally, I am a part of various projects based on immunology,  elephants, federalism, and other applications using techniques from mathematics, statistics, and data science.
