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, and signal processing and inference for arrays of chemical sensors. In my spare time I enjoy fencing, hiking, skiing, tennis, computer games, and spending time with my family!

In the article, “WPI Awarded $3M for Graduate Data Program” the Worcester Business Journal reported on WPI using a $3 million grant from the National Science Foundation (NSF) to establish a unique graduate curriculum to train the next generation of scientists who can apply chemical sciences along with data analytics, mathematics, and computing power to reduce energy usage, waste, and pollution. Elke Rundensteiner, professor of computer science, founding director of the Data Science program, and principal investigator on the grant, is collaborating with Michael Timko and Aaron Deskins, associate professors of chemical engineering, and Randy Paffenroth, associate professor of mathematical and data sciences, among others.
Randy Paffenroth, associate professor of mathematical sciences, computer science, and data science, told Boston-based WBZ radio how he is helping the U.S. Army create a thumbnail-sized chemical sensor to protect soldiers. In the five-minute segment, he noted that he is using a “combination of classic and new math to extract from these many sensors what’s in the environment.”
