After graduation, she took a position conducting environmental assessments for the Tennessee Department of Transportation.
​​
Evelyn received her B.S. from the Tennessee Technological University, in Spring of 2013, where she double majored in Biology and Wildlife & Fisheries Science, with a concentration in Environmental and Conservation Biology.

Christian Carter
M.S. 2014
Christian joined the Ervin lab in Spring semester 2013 and completed his thesis in May 2014. He worked on a variety of ecological studies to better understand the biology of a growing nuisance wetland plant species in the US Midwest - Butomus umbellatus (Flowering Rush).
Following graduation, Christian was employed by the US Forest Service in northern Arkansas before moving to New Mexico for a job with the US Forest Service's Nogales Ranger District.
​
Christian received his B.S. from the University of Arkansas, Little Rock in 2011, where he majored in Biology, with an Minor in Mathematics.
Thesis: Experimental assessment of Butomus umbellatus L. growth and expansion using a mesocosm approach
Rima Lucardi
Ph.D. 2012
Rima began work in the Ervin lab during Spring semester 2008. She studied population genetics of an invasive grass (Imperata cylindrica) in the southeastern US.
​
Rima was employed through the USDA Forest Service SCEP program for the last year of her doctoral studies. She relocated to their SRS lab in Athens, GA shortly after her December 2012 graduation.
​
Rima received her B.S. from the University of Texas at Arlington in December 2005, where she spent considerable time working in the lab of Dr. Laura Gough.
​
Dissertation: Multi-scale population genetic analysis of cogongrass (Imperata cylindrica) in the southeastern United States: introduction history, range expansion, and hybridization
Steven Hughes​
M.S. 2011
Steven began work in my lab during Summer 2007. He worked on projects related to invasive plant ecology in the Mid-South US (TN, AL, MS, AR, LA) as part of work funded by the USDA and USGS through MSU's Geosystems Research Institute. His thesis focused on habitat modeling for Blackland Prairie plant species in Mississippi.
​
Steven received his B.S. from Delta State University in Cleveland, MS. He left my lab for a position with the US Forest Service Center for Bottomland Hardwoods Research. He later took a position as Collections Manager for the University of Georgia Herbarium.

Lucas Majure​
M.S. 2007
Lucas worked as a graduate student in my lab from Fall 2004 until Summer 2007. He worked on projects related to invasion ecology in the Mid-South US (TN, AL, MS, AR, LA) as part of a larger USGS grant to MSU's Geosystems Research Institute. His primary contribution to that work was mapping of native cactus (Opuntia spp.), in support of efforts at monitoring the invasive cactus moth, Cactoblastis cactorum.
Lucas received the 2007 GSA Graduate Research Assistant of the Year award at MSU for his research on Opuntia and other floristic work. Lucas' thesis laid the groundwork for his Ph.D. studies in the taxonomy of southeastern Opuntia; that work began in the Department of Botany at The University of Florida in Fall 2007. He received his Ph.D. in summer 2012. He worked for a time as the "Biologist of New World Succulents" at the Desert Botanical Garden in Phoenix, AZ prior to taking a position as Assistant Curator at the University of Florida Herbarium.

Jason began work in my lab during the summer of 2002. He worked on projects to evaluate the potential effectiveness of Odonata (dragonflies and damselflies) at indicating freshwater wetland ecological integrity. Specifically, he assessed the short-term direction, pattern, and sensitivity of adult Odonata diversity response to mowing, fire, drainage, and other human activities.
Jason was awarded a Society of Wetland Scientists Student Research Grant (2004) and SWS Regional Best Student Presentation Award (Spring 2005). Jason took a position with the Nature Conservancy's Eastern New York Chapter, where he served as a Preserve Ecologist for the Albany Pine Bush Preserve. He completed his Ph.D. at Oklahoma State University and then moved on to a post-doc at the University of Arkansas. Jason later moved to a faculty position at Murray State University.
