Hannes Baumann (PI)


Hannes Baumann started the ‘Evolutionary Fish Ecology’ Lab in September 2014 to expand ecological and evolutionary frontiers via experimental, field, and modeling work. His work investigates, how coastal marine organisms will cope with the simultaneous changes in their environment caused by global and regional human activity, and how they are already adapted to environmental fluctuations in e.g. temperature, oxygen, or pH.

Local field work includes maintaining deployed sensors, frequent collections with plankton nets and beach seines, in addition to laboratory rearing of fish, physiological measurements, and otolith microstructure analysis – all of which can incorporate the help of interested and ambitious undergraduate students searching for hands-on experience and own projects.

Lucas Jones (MS student)


Lucas Jones started in summer 2019 as a master student in the Baumann lab after getting his bachelors degree from the University of Connecticut. Lucas started out as a volunteer in our lab 2017 and because of his dedication and experimental talent quickly became an indispensable asset to our scientific operations. He now continues to leverage his familiarity with our rearing system to further investigate the climate sensitivity and population characteristics of Northern sand lance (Ammodytes dubius), an important winter-spawning forage fish in the Gulf of Maine.

Kelli Mosca (MS student)


Kelli Mosca started in January 2020 as a graduate student in the Fish Ecology Lab. Kelli received her Bachelors degree in spring 2017 from the University of New Haven. She became a dedicated seasonal worker at the Connecticut Department of Energy and Environmental Protection (CTDEEP), where she assisted particularly with the sturgeon monitoring program. This has made her the best possible graduate candidate to work on our newly received CT SeaGrant project to look at age and telemetry data of Atlantic Sturgeon in Long Island Sound and the Connecticut River.

Max Zavell (PhD student)


Max Zavell started on his journey as a PhD student in our lab in fall 2020, after graduating in May 2020 with his Bachelor from the University of Rhode Island. Max is interested to work experimentally and continue exploring questions of coastal fish and climate change. In addition to Atlantic silversides (Menidia menidia), his work is breaking new ground for our lab by starting to work with Black Sea Bass (Centropristis striata). Growth, physiology, and sex determination of this northernmost grouper species are of great interest, given its recent, explosive increase in abundance in Long Island Sound and the larger northwest Atlantic shelf.

David Riser (MS student)


David Riser started his Masters in September 2020 after graduating with his Bachelor from the University of Connecticut and a Major in Marine Sciences. David already looks back on a successful career in the US Coast Guard, but now ventures to develop academic chops and expertise. In close collaboration with CTDEEP, he will analyze time series of Black Sea Bass catches in Long Island Sound and begin collecting and aging adult Black Sea Bass using otoliths. Welcome, David!
