David Guerra, Ph.D.


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 and remote sensing data, including lidar, hyperspectral, and satellite based data, to study natural systems in New Hampshire and around the world.  This research, which provides students the opportunity to employ many skills they develop in classes in a multidisciplinary exercise, was initiated through funding through a statewide EPSCoR - National Science Foundation grant. 

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