Primary Interest Areas:
My service on the Darien, Connecticut Environmental Protection Commission influenced my concept on how an environmental education can be used to serve the needs of a community to improve the environment.  One in-depth study resulted in a textbook on onsite wastewater treatment systems and how they can address community sanitation needs and recycle water in an efficient and environmentally-sensitive manner.

I have used and taught GIS to address community issues in watershed protection,  water quality mapping, open space analysis, historic preservation, 3-D analysis of watershed boundaries and air quality analysis.  I teach Desktop GIS as a MOOC on Google Classroom.

I have trained and led volunteer groups to monitor streams using the Izaak Walton League of America’s Save Our Streams program, training participants to identify benthic macroinvertebrates and perform field-based chemical analysis of the waters.  I have worked with golf courses to help them achieve certification in the Audubon Cooperative Wildlife Sanctuary Program, providing water quality monitoring information

Prior to teaching at Pace, my research was devoted to using scanning electron microscopy and energy-dispersive x-ray analysis to analyze particulates, concentrating on developing a signature to identify the fly ash from coal-fired power plants.

Graduate Student Theses
This link gives the titles and a description of each of the graduate student theses I have mentored at Pace University.

I created and maintain the Pace Pleasantville weather station.

Volunteer Work
Since 1986, I have been the contact for US Peace Corps volunteers worldwide to obtain free books through Darien Book Aid. 
This volunteer organization normall sends requested books to over 500 Peace Corps volunteers annually.

I play cello in the Carriage House Chamber Orchestra that meets in the Moose Room of the Rowayton Community Center.
