My primary area of research is environmental toxicology, which is the study of how pollutants affect ecological systems.  Although my Ph.D. research focused mainly on long-range transport of air pollutants into remote areas, I now do primarily locally-based research on pollutants.  Recently, my students and I have investigated:

  • the presence of pharmaceuticals and other emerging pollutants in the southern Cayuga Lake watershed - this is a large collaborative project with the Ithaca Areas Wastewater Treatment Facility, Cornell University, and the US Geological Survey
  • the effects of various pollutants on the swimming behavior of fathead minnows   
  • the effect of caffeine and carbamazepine on predator avoidance behaviors of fathead minnows
  • the accumulation of microbeads in the aquatic food chain and effects of mortality of Daphnia magna

I teach a variety of environmentally-related courses.  My favorite courses to teach are ones that have an international component.  I love teaching ENVS 204: Special Topics: Belize's Rainforests, Reefs and Ruins in the fall semester with a two-week trip in January.  You can read about the course from a student's perspective in FUSEI also offer ENVS 380:Sustainability in the Amazon Basin that includes a trip into the Amazon basin of Ecuador.


I also love teaching upper level electives such as ENVS 340: Topics in Pollution, in which we either examine the human health effects of pollutants or the effects of pollutants on ecological systems.  I often focus these courses on recent events or local issues.  I most recently developed a course in Environmental Technologies (ENVS 375) that delved into appropriate technologies for the developing world and cutting edge technologies for the developed world, and the use of space to address environmental problems on earth. 

Lastly, I often teach environmental seminars (ENVS 175 in Fall 2016),


I am very involved in promoting sustainability in education, at Ithaca College and beyond.  We published an article in Sustainability: The Journal of Record on Sustainability as an Academic Discipline.  I also led a NATO-sponsored workshop and co-edited a book on Addressing Global Environmental Security Through Innovative Educational Curricula. I also serve on the International Policy Advisory Committee.
