Research Staff

Our research staff are as diverse as the projects they work on. Whether they are conducting water quality monitoring or presenting research results at a national conference, our staff share a common goal—to further understanding of the environment through research, education, and outreach.


Mandi Gordon

Interim Associate Director, Research Programs; Senior Biologist

Gordon began working for EIH as a research associate in 2011. She obtained her M.S. in biology from Georgia Southern University and her B.S. in marine biology from Texas A&M University at Galveston. Her prior experience covers broad topics such as examination of physiological adaptations, biomechanics, ecological and environmental impacts on populations, and reproductive endocrinology. Gordon has had the opportunity to work with a wide range of vertebrate species, but her primary senior research role at EIH involves the study of turtles. Since working for EIH, she has participated in interdisciplinary projects ranging from water quality monitoring to population demographics and ecology.

Marc Mokrech

Senior Research Scientist

Mockrech's background is in civil engineering specialized in geographic information systems (GIS) and remote sensing. His current research focuses on spatial modeling considering an interdisciplinary approach for analyzing and understanding future environmental and socio-economic implications. He has more than 10 years in applying spatial modeling in a wide range of fields including coastal management and adaptation to future changes, impact assessment of climate change on urban and natural environments, hydrological and watershed analysis, terrain analysis, and uncertainty management in GIS-based models. Mokrech is currently investigating changes in landscape use and demographics and impacts on the local environment.
