Jason Macrander, Ph.D.

Assistant Professor of Marine Biology


As a teacher, I do not expect all of my students to become scientists, but I want them to be able to evaluate and understand biological concepts they encounter in the media and everyday life. My own experiences in the lab and improving myself as a teacher has inspired me to develop a student-centered active learning environment, which facilitates an understanding of biology and an appreciation of science.

I am an evolutionary biologist using comparative ‘omics approaches in sea anemones and other venomous animals to address questions concerning venom evolution, symbiosis, and protein function. In my research, I use sea anemones as a model to understand how ecological factors influence molecular diversity from a phylogenetic perspective.

Time I spend with students translating ideas from the text into scientific hypotheses they can test in the lab.

Being originally from Nebraska I had a strange obsession with marine life and SCUBA diving since high school. I quit my first job after about a month to pursue something that would get me "closer" to animals (albeit was working a concession stand at a drive through zoo in Nebraska). I did my undergraduate degrees in Biology and Fisheries & Wildlife at Nebraska and exhausted every avenue of Marine Biology research or training while I was there. I was lucky enough to participate in undergrad research in Roatan, Honduras using remote sensing to monitor and identify corals. I also was selected for Disney's advanced internship program, where I maintained aquariums and feed the fish at The Living Seas (now known as "The Living Seas with Nemo and Friends") in EPCOT.

I did one year of my Masters in Puerto Rico and although the proximity to the ocean was great I returned to Nebraska to complete my Masters. I went to The Ohio State for my PhD where I started working with sea anemones and venom, then the University of North Carolina at Charlotte for a postdoc.
