Ervin Lab Graduate Students

 

Present students

 

Michael Calloway (M.S.)

 

Michael joined the Ervin lab in Fall 2007.  He is working on a comparative survey of fishes in the Noxubee River - a tributary of the Tennessee Tombigbee Waterway (TTW; US ACE) - making a comparison of present-day fish assemblages with those present in the Noxubee prior to construction of the TTW and large-scale disturbance of the Tombigbee River.  Read more about the waterway.

 

 

Chris Doffitt (Ph.D.)

 

Chris Doffitt began work in my lab during Spring of 2007.  He is working on projects related to invasive plant ecology and distribution in the Mid-South US (TN, AL, MS, AR, LA).  This work is part of a USDA grant to Drs. Madsen and Ervin and a USGS grant to MSU's GeoResources Institute.  Chris received his M.S. from the University of Louisiana at Monroe and has worked in plant taxonomy and systematics for a number of years, including extensive survey work in Louisiana and Arkansas, and a stint with the Nature Conservancy in south Florida.  Chris' dissertation research is focused on geographic and systematic delimitation of species in the genus Amsonia (Apocynaceae).  He is working closely with our systematist, Dr. Lisa Wallace on molecular aspects of this work.

 

 

Chris Holly (Ph.D.)

 

Chris Holly began work in my lab during Fall of 2004, after receiving his undergraduate degree from Millsaps College in Jackson, MS.  He is working on projects related to invasive plant ecology in the Mid-South US (TN, AL, MS, AR, LA) as part of a larger USGS grant to MSU's GeoResources Institute.  His primary focus has been ecology of cogongrass (Imperata cylindrica) invasion.

 

 

Steven Hughes (M.S.)

 

Steven began work in my lab during Summer 2007.  He is working 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 GeoResources Institute.  Steven received his B.S. from Delta State University in Cleveland, MS.

 

 

Rima Lucardi (M.S.)

 

Rima began work in the Ervin lab during Spring semester 2007.  She plans to study the effects of an invasive grass (Imperata cylindrica) on soil microbial assemblages.  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.

 

 

Daniel Millican (Ph.D.)

 

Daniel joined the Ervin lab in Fall 2007.  He is finishing up a study of the effects of landscape structure and stream habitat characteristics on fish assemblages in tributaries of the Tennessee Tombigbee Waterway (US ACE) in eastern Mississippi.  Read more about the waterway here.  Daniel presently is working with the Nature Conservancy's Ozark Highlands Office in Fayetteville, Arkansas

 

 

Matt Roberts (M.S.)

 

Matt joined the Ervin lab in Fall 2007.  He is working on a comparative survey of fishes in portions of the Tennessee Tombigbee Waterway (US ACE) and one of its principle tributaries.  Matt is developing a comparison of food resources of present-day fish assemblages versus those in the system prior to construction of the TTW and large-scale disturbance of the Tombigbee River.  Read more about the waterway.

 

 

Nathan Sonderman (Ph.D.)

 

Nathan began work in my lab during Summer 2007.  He is working 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 GeoResources Institute, and on projects related to my participation in the NOAA Northern Gulf Institute.  Nathan received his B.S. from The Ohio State University and his M.S. from Middle Tennessee State University.

 

 

Where are they now ???

 

Jason Bried (M.S. 2005)

 

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 serves as a Preserve Ecologist for the Albany Pine Bush Preserve.

Brook Herman (M.S. 2005)

 

Brook began work in my lab during the summer of 2002.  Brook's work was aimed at development of tools for use in assessment and monitoring of freshwater wetlands, specifically vegetation assessment methods (based on the FQAI approach) and invertebrate assessment techniques (IBI-type approach).

 

After completion of her M.S. studies, Brook took a temporary position with the Nature Conservancy at the Kankakee Sands Restoration Project.  She then worked as a Plant Ecologist with Land Resource Management Group, Inc. in Bradley, Illinois.  Brook now is employed with the US Army Corps of Engineers in Chicago, Illinois.

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 GeoResources 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 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.
