Prior to that, I was the Co-PI on an NSF grant that demonstrated that demonstrated that fish egg boons represent a pathway for counter-gradient flow of nutrients from larger to smaller organisms in marine ecosystems at the University of Texas at Austin Marine Science Institute.<\/p>\n\n\n\n<p class=\"has-blue-gray-color has-text-color has-link-color wp-elements-18 wp-block-paragraph\" style=\"font-size:16px\">I earned my Ph.D. in aquatic resources from Texas State University, where my dissertation focused on the ecophysiology and food web dynamics of spring ecotone communities in the Edwards Aquifer. I also hold a master\u2019s degree in environmental science from University of Houston-Clear Lake, along with degrees in oceanography, fisheries, and zoology from the University of Mumbai. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Education Courses Taught About me I am an assistant professor of environmental science in the Department of Chemistry, Geosciences, and Physics at Tarleton State University.
