Personal statement

David grew up around the Great Lakes living in Chicago, Buffalo and Youngstown, NY.  As a Junior Sailor and Instructor at Youngstown Yacht Club he has spent a lot of time on or near the water and has seen first-hand the way Zebra Mussels have taken over the Lakes.  Growing up with a family that drove across country a few times, camping all the way, he has an appreciation for many of the landscapes that the continental United States provides.

After graduating from Lewiston-Porter High School in 2001, David then attended Binghamton University to study biology and graduated Cum Laude in 2005 with a BS in Biochemistry.  After working as a land surveyor for two years in Niagara Falls, NY he began work on teaching credentials at the University at Buffalo in 2007.  After a year and half in the Ed. M. program, and completing his student teaching experience, David transferred to the Chemistry Department to pursue a deeper understanding of the molecular world and get his hands dirty with research.  David is now a student in the Ph. D. in Chemistry program studying the fate of nano-materials in the environment.  His current research focuses on understanding the toxicity of quantum dots (QD) on the model earthworm E. Andrei.

David is currently planning to teach chemistry at the high school or college level after graduation but is open to any opportunity that includes working in science and education.  He plans to incorporate environmental themes and advocacy in his all his future work.  He sees local environmental issues as a hook to encourage students to learn everything they can about their world, including chemistry, so that they can become informed advocates for the environment they inhabit.
