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.

Moncie Wright, M.S.
Ph.D. student, Biology

Moncie's M.S. degree focused on invasive crayfish in Maryland streams. During her "free time" Moncie worked full-time as an environmental consultant. Here at Baylor, Moncie is focused on interactive effects of grazing biota and contaminants on stream periphyton. First, she is study algal and bacterial responses to titanium dioxide nanoparticles (TiO2NPs) with and without fish and snail grazing pressure in stream mesocosms. She is also studying periphyton responses to pulsed atrazine exposures with and without fish grazers. Her third chapter will explore the mechanisms driving periphyton responses to TiO2NPs under snail grazing pressure observed in the previous TiO2NP field exposure experiment using laboratory streams.

Caleb Robbins
Ph.D. student, Biology

Caleb joined the lab in Fall 2012. His first chapter of his dissertation will focus on microbial and nutrient uptake response to whole-stream dissolved organic carbon (DOC) enrichment in an Alaskan headwater stream. He is currently a core member of the Oklahoma Scenic Rivers Joint Phosphorus study, where the next facet of his research will involve characterizing DOC among distinct anthropogenic vs. natural sources and how these different forms of DOC may differentially affect microbial and photoautotrophic production in streams.

Stephen Cook
Ph.D. student, Biology

Stephen joined the lab in Fall 2013. He spent three years following graduation from college working on several projects ranging from harvest surveys on crabbing vessels in the Alaskan Bering Sea (yes the same ones featured on the television hit, Deadliest Catch) to collecting data on rocky intertidal communities on the Oregon coast. His first dissertation chapter will document remarkably large increases in macroinvertebrate densities following dissolved organic carbon additions to an Alaskan headwater stream, whereas his future work will focus on food webs along a steep phosphorus gradient in Ozark streams.

Brittany Perrotta
Ph.D. student, 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. She will be looking at snail grazing pressure on paraphyton dosed with titanium dioxide in laboratory streams. In the future, Brittany will be involved with the Duke mesocosm study where she will likely look at the effects of environmentally realistic nanoparticle concentrations on aquatic insects.
