I'm an Assistant Professor at the University of Houston-Downtown, where I focus on research related to animal behavior and genetics. I got my BS in Ecology & Evolutionary Biology at Rice University, where I studied the predatory behaviors of little aquatic damselfly larvae in the standstill ponds of East Texas. From there, I got my Ph.D. in Biology at Texas A&M University. For this research I studied the genetics of mating behaviors in two species of hybridizing swordtail fish that are found in the mountains of Hidalgo, Mexico. After that, I started studying all sorts of insects until I joined UH-D, where I'll be studying the behavior of house flies to gain a better understanding of chromosome evolution.
