I am currently a Professor of Physics at Saint Anselm College. Previously, I was on the faculty of Western Maryland College (assistant professor), Montgomery College (instructor), and The Bullis School (physics/economics teacher and football/lacrosse coach). 

As a graduate student and National Research Council (NRC) postdoctoral researcher, I developed laser systems for atmospheric sensing, in the photonics group at NASA-Goddard Space Flight Center (GSFC). For two decades, I worked with the Laboratory for Atmospheres from NASA-GSFC's on the development of a novel lidar (laser radar) system that employed a hologram of a point source as its receiver and scan mirror. Currently, I am using GIS software to map the structure of New Hampshire forests using airborne lidar data. This research is funded through a statewide EPSCoR - National Science Foundation grant that provides opportunities for students to participate in this important, multidisciplinary research. In addition, I also work with students on other research projects on Atmospheric Sensing, Laser Physics, Optics, and Fluid Dynamics. Some of this student research has resulted in published work. Please see my publication list for: An Introduction to Dimensionless Parameters in the Study of Viscous Fluid Flows, A Bernoulli's Law Lab in a Bottle, An Introduction to Laser Modeling Studies with a Nitrogen-pumped Dye Laser, A SAASE Outreach Project - Field Tests of Han-Held Haze Detectors, and Service Learning in Physics: The Consultant Model. 

As a native New Englander, I enjoy the outdoors in all seasons. I spend as much time as I can in the mountains of NH. I am trying to hike all 48 of NH's 4000 footers with my children and the whole family loves to ski, downhill and cross-country. 


Mapping the Rugosity of NH Forests with Lidar Data (2011-present)  As part of the state wide effort funded by the National Science Foundation's EPSCoR program  to quantify forest services, I am using ARCGiS software to produce maps of the Rugosity (standard deviation of tree height) of some of New Hampshire's experimental forests. This information will be analyzed along with other data compiled from other airborne instruments, satellites, and ground measurements. This multidisciplinary research provides excellent opportunities for students to learn valuable skills and to experience how a huge scientific undertaking coordinated.
