Arkov, Alexey, Professor. BS, MS, Moscow State University (Russia); PhD, University of Texas-Houston Health
Science Center. We are interested in understanding the genetic and molecular mechanisms
of germline and stem cell development. In addition, we aim at the identification of
novel molecular factors which promote longevity of living organisms. email Dr. Arkov | Arkov Lab.
Beckers, Oliver M., Assistant Professor. MS, Friedrich-Alexander University (Germany); PhD, University of Missouri Columbia.
I am fascinated by the evolution of animal behavior. More specifically, I study how
the environment (i.e., phenotypic plasticity), female choice (i.e., sexual selection),
and parasitoids (i.e., natural selection) affect the evolution of reproductive communication
in insects. My lab is currently working on two of the only three described Orthopteran
species that exhibit phenotypic plasticity in their mating calls. email Dr. Oliver Beckers | youtube | Beckers lab.
Bried, Jason, Lecturer. BS, Paul Smith's College (New York); MS, Mississippi State University; PhD, Oklahoma
State University. I'm a community ecologist, wetland ecologist, and odonatologist.
I study spatial community patterns and drivers, wetland classification and bioassessment,
and am interested in anything related to aquatic insects (especially dragonflies and
damselflies). email Dr. Bried | Bried Lab.
Canning, David R., Associate Professor and Houston Endowed Chair of Pre-Medicine. BSc [hons], Manchester University; DPhil, University of Oxford. Research Interests:
We study the epigenetic factors affecting the differentiation of neural stem cells

Biologist. email Dr. Caudell.
Cooper, Michael R., Lecturer. BS, MS Murray State University; PhD University of Louisville. My background is in
microbiology. I have studied nitrogen fixation in an Agrobacterium species isolated from the Ledbetter Embayment. This was followed by the discovery
