Welcome to the Horner lab in the Department of Biology at CSUSB!

My research and lab group are focused on the mechanisms that shape locomotor strategies in animals, and how proximate (e.g., traversing different environments) and longer-term (e.g., aging, disease) perturbations may affect performance. My past research has investigated the interplay of substrate and locomotion in a variety of vertebrates, including lungfish, rodents, and ferrets. Since joining CSUSB as an Assistant Professor of Biology in September of 2013, I have focused my research on muscle function in small mammals. Although small mammals such as rats and mice have frequently been used as research models, the integrated in vivo function of muscles and tendons in crouched mammals is still not well understood.

December, 2016: Graduate students Nick and Alex traveled to New Orleans to present some of their master’s thesis research findings at the annual SICB conference. Both Alex and Nick have defended their proposals and are looking forward to defending their theses in 2017! Dr. Horner is skipping this year’s conference to help the newest lab member adjust to the world.

November, 2016: The newest publication from the lab investigates the cost of moving in (not creating) tunnels. We simulated tunnel conditions in the lab by creating respirometry chambers with reduced ceiling heights to measure locomotor energetics in ferrets and degus. Both species showed an elevated cost of locomotion when crouch-walking to move through the tunnel, but the ferrets were surprisingly economical in all forms of voluntary locomotion when compared to other here.

October, 20srep33734-f116: Peter Falkingham and I just published our paper on trackways produced by lungfish in Nature Scientific Reports. You can access the paper here. This paper was borne of many chats over a few beers at Brown University, where we both postdoc’d. Like many ideas, it was conceived in beer and implemented with coffee! We’re pleased and quite proud it’s finally seeing the light of day.
