Research

My background is in probability theory, analysis of stochastic processes, and the underlying mathematics: in short, the study of randomness.

Past work focuses on the reliability of stochastic networks, renewal theory, random walks, stochastic game theory, stochastic measure theory, and particularly the application of discrete and continuous operational calculus to stochastic processes. I continue some work in these areas and on some new ideas related to probability flux.

Most of my newer projects focus on machine learning, computer vision, deep learning, and statistical analysis focused on problems in aerospace engineering, climate science, sustainable global development, cybersecurity, and mathematical biology.
