yo1I am a research associate in the College of Marine Science at the University of South Florida (USF), St. Petersburg. I received my Ph.D. in Ocean Sciences from the University of Southern California in 2009, worked on several projects in contrasting areas (wetlands and lakes), and joined  USF in 2011.

My research focuses on understanding how ecosystems respond to natural and induced disturbances in aquatic and coastal environments.  As an environmental geochemist, I have worked in a wide range of different projects with particular emphasis on the effects of eutrophication, tidal inundation gradients, and petroleum contamination on different ecosystem levels. I have studied specific molecules (e.g., carbon, hydrogen), natural cycles (e.g., nitrogen), microbes (e.g., N2 fixers), and marine fauna (e.g., mesopelagic fishes). In my work, I include isotopic, molecular, and organic geochemical analyses in water, sediments,  and organisms. Results from my research are used to determine the effects of disturbance on marine environments and to elucidate natural processes. I have a particular interest in identifying geochemical indicators of ecosystem change.
