He studies genetic differentiation and evolution in structured populations. His research combines theoretical and experimental approaches to study the effects of selection among individuals, populations and communities. One of his major areas of interest is how certain types of genetic variation, such as epistatic interactions among loci, can contribute to a response to selection in a subdivided population even though they cannot contribute to a response to selection in a large panmictic population.

My research interests lie at the intersection of Computer Science theory and practice. I develop innovative formal methods based on programming language type theory, mathematical logic, and computability theory in general. I also build cyber-physical systems based on these technical innovations, and explore applications of these methods to important practical problems, especially related to cybersecurity, health, and the environment.

He is a practicing clinician treating abnormal heart rhythms by placing wires inside the heart. His research focuses on the chaotic abnormal heart rhythm, atrial fibrillation. He studies fibrillation in a computational model, as well as in swine and humans. Dr. Spector and his team have designed a new type of electrode array and mapping system that allows doctors to determine how to treat patients on a case by case basis. He is the founder and President of VisibleEP (computer modeling software for electrophysiologic research and education) and CoreMap (a clinical cardiac mapping company). The research in our laboratory has ranged from molecular biology and voltage clamping studies of single ion channels all the way to whole heart studies and computational modeling. The consistent theme is the over arching question itself; "how can we better understand atrial fibrillation and use that understanding to better treat it?"
Professor, Vermont Space Grant Consortium & NASA EPSCoR Program Director, Department of Mechanical Engineering
His research lies in the area of high-fidelity orbital mechanics (astrodynamics) simulations and the gravitational modeling required for these simulations. The particular focus lies in close-proximity orbits about small irregular celestial bodies, such as asteroids and comets, whose irregular topology and variable composition result in complex gravitational fields. In addition to this fundamental work, his research also involves mission trajectory planning and optimization using evolutionary computing approaches.
