Welcome to my website. 

My teaching, research and outreach programs at Penn State are based around environmental effects on plant growth and development.  My primary emphasis area is on air quality impacts on terrestrial ecosystems (primarily flora).  I also coordinate the efforts of the Air Quality Learning and Demonstration Center, which is the only site in the nation and potentially the world that is dedicated to educating the public about air pollutant effects on plants.

An Ozone Pollution Teaching Module for 9 - 12 grades can be found here.

More in depth information on my program can be attained by clicking on the above links or by visiting the Department of Horticulture.

Additional information can acquired by contacting me directly by phone (814-865-5587) or by email.

Thanks for visiting and have fun exploring.
