Bonvillain CV

I am an aquatic ecologist with interests ranging from ecosystem-level physical processes to organismal biology and ecology.  I enjoy Louisiana and have spent my career working in the multitude of aquatic ecosystems throughout the state.  Although crayfish and fish are my principal research organisms, all biota in the aquatic realm pique my interest.  Take a couple of minutes to look around and contact me with any questions.

Jordan Logarbo
Jordan is from Geismar, Louisiana and graduated in Spring 2017 with a B.S. in biology, marine biology concentration.  Her honors undergraduate research examined the physical and physiological thermal maxima of two sympatric crayfishes in Louisiana, Procambarus clarkii and P. zonangulus.  Jordan is pursing an M.S. degree at LSU.



Lauren Kong
Lauren is from Alamo, California and graduated from Mills College with a B.A. in biology and a minor in environmental studies.  She graduated from Nicholls in Fall 2017 with an M.S. in Marine and Environmental Biology.  Her thesis examined population characteristics of Procambarus clarkii from hydrologically impaired areas in the Atchafalaya River Basin.





Alexa Ballinger
Alexa is from Reno, Nevada and graduated from Arkansas Tech University with a B.S. in fisheries science.  She graduated from Nicholls in Fall 2018 with an M.S. in Marine and Environmental Biology.  Her thesis examined crayfish population characteristics in two hydrologically different Louisiana river-floodplain systems.
