Kelli Mosca (MS student, 2020-2022)
![Kelli-Mosca---sturgeon_defense](https://befel-marinesciences.media.uconn.edu/wp-content/uploads/sites/938/2022/03/Kelli-Mosca-sturgeon_defense.png)
Kelli Mosca received a Bachelors degree from the University of New Haven in spring 2017 and started in January 2020 as a graduate student in the Fish Ecology Lab. She had already become 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 perfect candidate to work on our CT SeaGrant project to look at age and telemetry data of Atlantic Sturgeon in Long Island Sound and the Connecticut River. Kelli worked hard and independently, mastering not only the technical aspects of the project but also the challenges imposed by the COVID pandemic that sadly marked her entire time as a graduate student. Undeterred, Kelli graduated with her Masters on 21 March 2022, presenting her thesis titled
"Atlantic sturgeon (Acipenser oxyrinchus) Growth and Habitat Use in the Connecticut River and Long Island Sound" (Link to recording).

Emma Cross (Post-doctoral researcher 2017-2019)
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 our lab, Emma transitioned to working with fish, particularly Atlantic silversides, testing how fluctuating pH and oxygen environments typical of nearshore environments affect early life survival and growth. Emma was also instrumental in all of our follow-up, ongoing work on sand lance sensitivity to ocean warming and acidification.
Emma was an incredible enrichment to our lab, and has now (September 2019) started her new faculty position as Assistant Professor in Coastal/Marine Science at Southern Connecticut State University (New Haven, CT). Her proximity will sure enable lots of collaborative work in the future!

Chris Murray (PhD student 2014-2019)
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 studyied multi-stressor effects of OA and hypoxia on coastal marine fishes. He had an outstanding, large part in designing and building ALFiRiS, our automated larval fish rearing system in UConn Rankin Seawater lab. After 4 phenomenally productive years, Chris defended his PhD in December 2018 and graduated in May 2019 with this PhD from UConn.
His thesis titled
An experimental evaluation of the sensitivity of coastal marine fishers acidification, hypoxia, and warming
is publicly available at the OpenCommons Site of the UConn Library.
After a productive post-doc on the west coast with the University of Washington (2019-2021), Chris wrote a successful NSF postdoctoral fellowship proposal and is thus currently working with Neel Aluru (Aluru Lab) at Woods Hole Oceanographic Institution, taking Atlantic silverside research to new levels. And he recently became a co-PI on our new sand lance grant, thereby ensuring further scientific productivity together.

Deanna Elliott (NSF REU student 2019)
Deanna Elliott is a junior at Arizona State University who joined the Baumann lab in summer 2019 as our third NSF-REU student. Deanna has experimented with locusts before, but now became an expert fish rearer. For her REU-project she reared Atlantic silverside larvae under different feeding regimes to create fish of different body sizes and then analyzed them for trace levels of mercury in their tissue. She tested the hypothesis that mercury concentrations in fish can be used as a proxy for ingestion rates, which are important to trophic ecosystem models to perform better.Great job, Deanna!

Julie Pringle (MS student 2016-18)
Julie Pringle started her MS in the Baumann lab in September 2016 and graduated in December 2018. During her time, Julie painstakingly investigated the growth and selective survival in juvenile Atlantic silversides (Menidia menidia) collected in fall 2015 in Mumford Cove. She was the first student in our lab to fully use our Image Analysis system, counting more than 30,000 individual increments in 300 of her selected specimens. Her research shed new light on a particularly intriguing aspect of silverside life history; i.e., that this species exhibits temperature-dependent sex determination. Under laboratory conditions, colder temperatures produce more females than warmer temperatures, which should lead to females being born earlier during the season than males. However, Julie's study showed that survivors at the end of the growing season consist of more females than expected and that those females were larger NOT because they were born earlier, but because they grew significantly faster than their male conspecifics.During her time, Julie never shied away from selflessly helping other students and the lab with tasks unrelated to her thesis, something we truly loved about her and will always be grateful for. She also became a brilliant Teaching Assistant and was a loved and active member of the graduate student community.
Julie has moved back now to Martha's Vineyard, where she started her new position as Field Science Coordinator for the local Great Pond Foundation. Julie says:
"There's a really an amazing network of wildlife biologists at various organizations on the Vineyard, and I'm very excited to be working side-by-side with so many, who originally encouraged me to become a scientist. I'll be doing field work, but also data analysis and working with interns, so it will be a fun combination of different types of work."
Julie's thesis research has recently been published in Marine Ecology Progress Series:
- Pringle, J.W. and Baumann, H. (2019) Otolith-based growth reconstructions in young-of-year Atlantic silversides (Menidia menidia) and their implications for sex-selective survivalMarine Ecology Progress Series 632:193-204

Sydney Stark (NSF REU student 2018)
Sydney Stark joined our lab from June to August 2018 as our second REU (Research Experience for Undergraduates) student in collaboration with Mystic Aquarium. Sydney is a Junior at the University of North Carolina Wilmington and interested in aspects of marine conservation and effects of climate change. Sydney spend her summer testing a prototype of a light trap designed to catch larval and juvenile fish and used it to infer seasonal patterns of ichthyoplankton abundance in nearshore Long Island Sound. In just a short period of time, Sydney became a true ichthyoplankton taxonomist and found that light traps truly work in our waters. Well done Sydney, and all the best for the next career steps!In her hometown, Sydney's REU project already received coverage by the local newspaper. See here!

James Harrington joined the team in May 2017 to help with our various endeavors rearing fish in the Rankin Lab. He is currently maintaining population crosses of Atlantic silversides from different locations along the Atlantic Coast, which together with our colleagues from Cornell will facilitate describing and annotating the genome of this species. He is also helping with our biweekly beach seine surveys, assisting Chris with large factorial CO2 x O2 experiments on Atlantic silverside offspring, and has lent a hand to our REU student Elle with her summer work.He's is currently working as an instructor for the New England Science & Sailing Foundation (NESS) in Stonington, CT
