Ryan King with Alligator
Ryan S. King, Ph.D.
Professor and Graduate Program Director, Biology

King directs students and manages all research projects in the aquatic ecology lab.

King is a bit of a flyfishing fanatic and prone to brag about fishing experiences (the 7.5', ~200 lb Alligator Gar in photo, which was caught near campus, was released unharmed).

Jeffrey A. Back Ph.D.
Baylor Univ.

Jeff is a world-class taxonomist and maintains one of the largest personal collections of aquatic Hemiptera and Coleoptera any of us has ever seen. Jeff generated an amazing data set on nutrient stoichiometry of macroinvertebrates differing in their life history traits across developmental stages for his dissertation at Baylor, which he defended in 2013. He remains a core collaborator with our lab as instrument specialist with CRASR and QA/QC officer on the Oklahoma Scenic Rivers Joint Phosphorus Study.

Daniel Hiatt, M.S.
Ph.D. student, Biology

Daniel studied water quality and its influence of biota in experimental streams for his master's thesis. Here, he is a core member of the Alaska headwater stream team and is studying the influence of nutrient availability on periphyton growth and enzyme activity in salmon-rearing streams of the Kenai Peninsula and in subtropical limestone streams in Texas. He has published 2 papers from his dissertation (Freshwater Science and Hydrobiologia, respectively) and is wrapping up his third chapter with intent on graduating in 2019. Dan is currently a Research Associate at the University of Illinois, Champaign-Urbana, his home state.

Brittany Perrotta
Ph.D. candidate, Biology

Brittany joined the lab in Fall 2015, leaving an oil and gas position as a Process Improvement Specialist optimizing the manufacturing processes of drill pipe through Lean and Six Sigma. Brittany is currently focused on the effects of titanium dioxide (TiO2) nanoparticles on food webs. Brittany was heavily involved with a wetland mesocosm study at Duke University where she focused on the effects of environmentally realistic nanoparticle concentrations crossed with nutrient enrichment on aquatic insect emergence, consumer-mediated nutrient recycling (snail excretion rates), and other contributions to overall study (e.g., she coauthored papers published in Ecological Applications and ES&T, both in 2018).

Zach Moran
Ph.D. student, EEES (Ecological, Earth, and Env. Sci)

Zach has a B.S. in Biology from Virginia Tech, where he was an active researcher in Prof. Don Orth's lab (leading to a first-authored publication on use of DNA barcodes for classifying diet of non-native Blue Catfish) and an M.S. in Fisheries & Wildlife from Arkansas Tech (where is further studied ecology of Blue Catfish). Zach joined the Aquatic Ecology lab in Fall 2019 as a PhD student in the TIEEES program to lead a study on population genetics and ecology of Longnose and Alligator Gar on the Brazos River.
