I am an assistant professor interested in evolutionary biology, behavioral ecology, and behavioral neuroscience. I completed my PhD in 2007 with Jonathan Losos and Alan Templeton at Washington University, and conducted postdoctoral research with Juli Wade at Michigan State. Clickhere to see my CV.

Interested in joining the lab? I am always looking for motivated undergraduates interested in field- or lab-based research on lizard behavior. If you think this might be you, read the lab website carefully and email me with a description of yourself and why you're interested in the lab.
Terrin is a senior McNair Scholar majoring in Biology, and she is studying the relationship between behavior and temperature in Texas spiny lizards (Sceloporus olivaceus). Terrin plans to pursue a Master's in Public Health after graduation.
Michael is a senior Neuroscience major studying brain laterality in green anole lizards. After graduation in December 2013, he'll begin his career as a technician in the Johnson Lab! He plans to pursue a graduate degree in neurochemistry.
Chris is a senior Biology major, and he's working on a project to study associations between the modes of lizard communiation and the evolution of their brain morphology. He plans to attend graduate school in evolutionary biology after graduation.
Jordan is a senior double-majoring in Biology and Mathematics, and she's working through the Integrated Research in Biology and Math program to develop a model of lizard metabolism, and conducting a thesis on dominance ranking. Jordan is our resident specialist on coding in R!
McKenzie is a junior Biology major, and she is a part of the Integrated Research in Biology and Mathematics program. She's working to determine a model of lizard metabolism, and is the lab expert on bomb calorimetry. She plans to attend medical school after graduation.
Bonnie is our lab technician extraordinaire. She graduated from Grinnell College with degrees in Biology and Music in 2012, and after arriving at Trinity in November, she quickly became involved in all the projects in the lab! Bonnie plans to attend graduate school in evolutionary genetics.
Jamal is a sophomore student at Trinity, planning to major in Biology. Jamal has just started working in the lab, but he's already become an important part of the group. He's considering attending medical school after graduation.
Alyssa is a junior Biology major and Beckman scholar, and (in collaboration with Dr. David Ribble) she is using population genetics to study the effectiveness of urban greenways for Texas spiny lizard dispersal. She plans to attend graduate school after graduation.
Lauren is a junior double-majoring in Biology and Environmental Studies. Her work in the lab investigates whether brain morphology is associated with invasive species biology in Texas lizards.
Michelle is a junior Biology major studying the evolutionary relationships between muscle physiology and locomotor behaviors in lizards.
