Hannah Cohen is is a PhD student with the Freshwater Conservation Ecology Lab in the School for Environment and Sustainability at the University of Michigan. She received her Bachelor of Science in Biology from the University of Hawaiʻi at Mānoa. During her Master's at Georgia Southern University, she studied local adaptation of feeding morphology and performance in fishes. For a few years she also worked as a lab manager at Rutgers University, managing both a molecular lab and a zebrafish laboratory. Her interests mainly lie in historical ecology and intraspecific variation of morphological traits in response to anthropogenic impacts.
