Biography

I am a quantitative ecologist with the Environmental Laboratory at the U. S. Army Engineer Research and Development Center in Vicksburg, Mississippi. My career with the Corps of Engineers began in the 1990’s as a student contractor, a position that provided mentoring and technical training in fisheries-related ecological research and field data collection, as well as an immersive introduction to our civil works and water resources missions. After earning a B.S. in Biology from the University of Texas at Dallas, I gained valuable experience assessing aquatic impacts from navigation and flood control projects on the Arkansas and White Rivers, Grand Prairie region of Arkansas, Yazoo River Basin tributary streams, and San Antonio River, among others. Additionally, our team devoted a large portion of its research efforts to the life history and conservation of the endangered pallid sturgeon (Scaphirhynchus albus) throughout the Lower Mississippi River, culminating in a comprehensive conservation plan and a non-jeopardy biological opinion from the U. S. Fish and Wildlife Service in 2013.
 
I left ERDC to pursue a Master of Applied Statistics and Ph.D. in Wildlife and Fisheries Science at Louisiana State University. My research at the School of Renewable Natural Resources focused primarily on evaluation of habitat impairment in low-gradient, coastal plain streams. While there, however, I was privileged to assist with projects throughout the state, including the Atchafalaya Basin and the lower Pearl River.
 
My recent work and current research interests back at ERDC include: freshwater habitat restoration assessment using empirical models, river-floodplain connectivity and ecological services within the Lower Mississippi River batture, and management of invasive Asian carps and other aquatic nuisance species. Support from the Mississippi River Geomorphology and Potamology program at the USACE Mississippi Valley Division has provided the opportunity for interdisciplinary collaboration with many enthusiastic and dedicated river scientists and engineers. Thus, I am grateful that my education and professional development continue daily.
