Originally from St. Louis, MO, Ed obtained a BSc in Biology from St. Louis University, a MSc in Biotechnology from Northwestern University and a PhD in Marine Biology & Fisheries from the University of Miami (2010). Ed earned a USEPA Science to Achieve Results (STAR) fellowship to help fund his PhD studies focusing on the aquatic toxicology of lead to freshwater organisms. Between obtaining his MSc and PhD, Ed worked for 9 years as a Research Associate holding positions at the University of California San Francisco, Incyte Genomics and the University of Miami Miller School of Medicine. Since completing his PhD, Ed has held two Postdoctoral Associate positions at the University of Miami’s Rosenstiel School of Marine and Atmospheric Sciences.

During his first position in the lab of Mike Schmale, Ed’s research focused on the molecular characterization of the aging nervous system of the sea hare, Aplysia californica. His second postdoctoral position was in Martin Grosell’s lab studying the short- and long-term effects of the Deepwater Horizon (DWH) oil spill on commercially important pelagic fish species such as mahi-mahi and cobia. Findings from this work have shown that brief exposure of embryonic/larval or juvenile mahi mahi to DWH oil reduces their maximum swimming speeds, likely hindering their ability to perform tasks critical for survival and reproduction such as catching prey and carrying out spawning migrations. Additionally, embryonic exposure to DWH oil results in impaired cardiac development and function, potentially contributing to the observed reductions in swimming performance.

Continuing in Martin’s lab as part of RECOVER, Ed will further investigate the underlying mechanisms behind these oil-induced swimming effects using a variety of approaches including swim tunnel respirometery, kinematics and by evaluating impairment to cardiac development utilizing in vivo microscopic morphometrics. Additionally, given the likely transient nature of an exposure to oil in the wild, it will be important to better understand the extent to which such effects are reversible once an exposure has passed. In order to answer questions of this nature, a large focus of this of work will involve using transient exposures followed by transfer to clean water for various periods of time and then examining relevant biological endpoints to assess recovery, including those described above.
