I regularly teach undergraduate and graduate courses in deep learning, machine learning, and probability, as well as honors calculus courses.
My academic background is in probability theory, stochastic processes, and the underlying mathematics: in short, the study of randomness.
I lead the NEural TransmissionS (NETS) research group. We focus on developing deep learning models, traditional machine learning, and statistical analysis for applications in aerospace, life sciences, and glaciology.
Outside academia, I have industrial experience in algorithm development, data science, and educational writing as well as current projects with non-profit Engage-AI using machine learning to extract insights for global development data.
