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 focuses on the central question, 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 variability 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.

Emma Cross (Post-doctoral researcher)


Emma Cross joined our team in September 2017, after receiving her PhD from Cambridge University, UK, in August 2016. Her previous work focused on the CO2-sensitivity of polar and temperate brachiopods, a group of ancient, sessile calcifiers that build large shells but are unrelated to mollusks. In addition to experimental approaches, she examined historical collections of specimens from New Zealand. Her findings suggest that brachiopods can cope with acidifying oceans by compensating for increased shell dissolution by increased shell thickness. Emma now transitions to working with fish, particularly Atlantic silversides, testing how fluctuating pH and oxygen environments typical of nearshore environments affect early life survival and growth.

Chris Murray (PhD student)


Christopher Murray started his PhD at UConn/Avery Point in September 2014, after finishing his MS in May 2014 at Stony Brook University, NY. While building on his experience in ocean acidification research, for his PhD he is now interested in studying multi-stressor effects of OA and hypoxia on coastal marine fishes. He has been instrumental in designing and building a state-of-the-art experimental unit that allows rearing of fish early life stages under static and fluctuating conditions of factorial CO2, O2, and temperature combinations.

Julie Pringle (MS student)

Julie Pringle started her MS in the Baumann lab in September 2016. Prior to coming to Avery Point, Julie graduated Tufts University in 2014 and was a technician in a larval fish ecology lab at Woods Hole Oceanographic Institution. At WHOI, she studied the trophodynamics of small pelagic fishes in the Western Atlantic. She will continue to work with forage fishes as a graduate student, investigating the growth and selective survival in Atlantic silversides (Menidia menidia) collected in Mumford Cove.

Callie Concannon (MS student)

Callie Concannon will start in fall 2018 as a master student and newest member of the Baumann lab. She is going to work on our new NSF project aiming to elucidate the genomic underpinnings of local adaptation in the Atlantic Silverside. Welcome, Callie!
