Personal statement

Susan Mackintosh is a graduate with a Ph.D. in Analytical Chemistry.  Growing up in the Adirondacks of upstate New York and spending each summer on Chateaugay Lake, NY sparked her lifelong fascination and understanding of nature.  This curiosity motivates Susan to study the environment through chemistry and participate in the ERIE-IGERT program.


In 2008, Susan graduated from SUNY Oneonta with a B.S. in Chemistry receiving an Academic Achievement award.  In the fall of 2008, she enrolled at the University of Buffalo to continue her studies and pursue a Ph.D. in Chemistry.  Due to her interests in the environment Susan joined Dr. Diana Aga’s research group which specializes in Analytical Environmental Research.  Her current work involves structural identification of the metabolic pathway of synthetic estrogen within wastewater treatment.  This is significant as estrogens can have various adverse effects on species within an ecosystem.  The degradation  products of these estrogens can also produce the same effects; therefore, the identification of these compounds is essential.  Additionally, Susan will be studying the extent of biomagnification and bioaccumulation of brominated flame retardants within the food web of Lake Erie.  Understanding the presence and impacts of these persistent organic pollutants on ecosystems is imperative especially when working towards restoration.

In the long term, Susan plans to conduct research in the area of Environmental Chemistry in either an industry or government setting.  She hopes to continue working with methods for identifying emerging contaminates believing this provides an important understanding of the degradation of ecosystems, and as a consequence, ways degradation can be avoided.  Susan looks forward to participating in the ERIE-IGERT program and feels her research will benefit through the interaction with fellow IGERT students from different academic disciplines.
