Randy Paffenroth

My research focuses on compressed sensing, machine learning, signal processing, and the interaction between mathematics, computer science and software engineering. My interests range from theoretical results to algorithms for tackling practical applied problems, and I enjoy problems most when mathematical results lead to efficient software implementations for big data. I am looking forward to working with students at all levels and backgrounds who share an interest in mathematics, software, or data. Some problems that have captured my interest include network analysis for cyber defense; signal processing and inference for arrays of chemical sensors; and compression and analysis of geospatial data. In my spare time I enjoy fencing, hiking, skiing, tennis, computer games, and spending time with my family.
