Research – Dr. Locklin’s Lab

My research interests are in the fields of aquatic ecology and entomology. I spent a great deal of time in or near various bodies of water as a kid growing up in Texas, and I suspect that exposure guided me into a career as a biologist.

I am always looking for students who want some research experience. That experience can range from ‘helping out’ in the field or lab to developing an independent project. Have a look through the site using the links above to see what we’re up to. If you are interested, come by and let’s talk!

J.L. Locklin

Lab Leader & Mentor:

Dr. Jason Locklin (right)

Dr. Jason Locklin mentors and directs all of the research in the lab. He teaches General Biology, Human Anatomy & Physiology, and Biological Research Methods at Temple College. Because learning doesn’t only occur in a classroom (most actually happens in the lab and field), Locklin tries to get biology students involved in his research to promote the understanding of biological knowledge as well as the process of science. At Temple College, Locklin enjoys guiding community-college student research that addresses key questions and hypotheses in the fields of aquatic ecology and entomology.
