Current Students and Lab Members

Peter Flood (Postdoctoral Researcher, NSF-EAGER Project then Coregonine Restoration Framework Modelling), began Feb 2023

Peter's Bio: I am an aquatic population and community ecologist who primarily studies fishes. My research focuses on how fish populations and communities are responding to anthropogenic stressors (e.g., climate change, hydrologic alteration, and invasive species). During my PhD at Florida International University, I investigated drivers of trophic dynamics in space and time with an emphasis on effects of invasive species. My work in the Alofs lab will use museum specimens and a trait-based approach to disentangle the impacts of climate change from other environmental stressors on body-size across species in freshwater fish communities. 

Kelly Hoyer (Postdoctoral Researcher, Cooperative Institute for Great Lakes Research, co-mentored with Steve Pothoven), began Sept 2024

Kelly's Bio: I am an aquatic ecologist specializing in fish communities. My primary interests lie in how anthropogenic stressors (i.e. climate change, urbanization, facilitation of invasive species) affect changes in community dynamics and life history strategies of fishes. During my Ph.D. at Central Michigan University, I investigated how metabolism, growth, diet, and vulnerability to predation differed between Lake Whitefish and Cisco, two coregonine (family Salmonidae) species native to the Laurentian Great Lakes. My work in the Alofs lab through CIGLR will use historical museum specimens of larval and juvenile coregonines to determine how growth and diet of these age-0 fishes have changed due to dreissenid mussel invasions throughout the Great Lakes.  

Hannah Cohen (PhD Student), began Fall 2024

I am interested in how anthropogenic influences have shaped modern populations and communities of fish and the surrounding environment. Specifically, my interests lie in intraspecific variation over time and species interactions. In the beginning of my scientific journey I earned my B.S. in Biology from the University of Hawaiʻi at Mānoa. From there, I continued my education to receive a Master's degree from Georgia Southern University. My thesis research focused on local adaptation of Trinidadian Guppies populations and their feeding kinematics. Before joining the Alofs Lab, I spent several years as a lab manager at Rutgers University, maintaining a zebrafish facility and molecular lab. 

Lian Anderson (PhD Student), began Fall 2025.

Postdocs

Katelyn King (Postdoctoral Researcher, CHANGES Project through April 2023 and now Coregonine Restoration Framework Modeling) April 2021-Oct 2024; now Fishery Research Biologist at Institute for Fisheries Research, Michigan DNR

Katelyn's Bio: I am a landscape fisheries ecologist and data-intensive scientist. I enjoy exploring how freshwater ecosystems interact with each other and the landscape across multiple spatial scales to understand patterns of fish biodiversity and how those patterns might respond to global change. During my PhD at Michigan State University, I studied nutrients and fish communities in hundreds of waterbodies, including lakes, wetlands, and streams across the contiguous United States. My work will continue as a part of the Alofs Lab and the CHANGES project, as I investigate fish species distributions in lakes using contemporary and historical datasets across Michigan, which are integral to understanding and predicting freshwater biotic responses to global change.
