Tyler Chidsey (he/him/his) is the Rotjan Lab manager and research technician assisting Randi in marine conservation endeavors with the Blue Nature Alliance. Tyler graduated from BU with a Bachelor of Arts in 2022. He majored in Marine Science and minored in Biology, mentored by Dr. Wally Fulweiler and Dr. Alia Al-Haj. He spent his undergraduate years investigating the biogeochemistry of coastal ecosystems, culminating in a senior honors thesis exploring the influence of decomposing Zostera marina wrack on greenhouse gas fluxes on New England sandy beaches. After graduating, Tyler served as a biogeochemistry intern at The Emerald Tutu, a coastal resilience startup pioneering a network of salt marsh floats to reduce wave action and ameliorate water quality in Boston Harbor. He designed experiments for field and lab tests of prototypes’ nutrient uptake capabilities as well as built the framework for a biogeochemical model to assess the ecological impacts of floats on Boston Harbor and vice versa. He is now working on his MS in Biology, studying the habitat use of pelagic sharks in MPAs in the Gulf of Mexico and Caribbean Sea. When not in the lab, you can find Tyler surfing waves at the nearest beach, buying too many books at local bookstores, or tending to his many many houseplants. Google Scholar |

Dr. Steve Auscavitch (he/him/his) is a Visiting Researcher in the Rotjan Lab. His research broadly seeks to understand ecological patterns and processes in deep-water coral ecosystems, particularly on seamounts. His current project in the lab seeks to identify and describe protected deep-water coral biodiversity, as well as patterns in phylogenetic community structure, in the equatorial Pacific and surrounding waters. His work leverages data collected from remotely operated vehicles with existing collection resources present in museum archives. Steve is also an active member of the Corp of Exploration on the E/V Nautilus where he has contributed as science lead and science data manager on several cruises since 2014. He received his BS in Marine Science from the University of Connecticut at Avery Point, his MS in Marine Biology at the University of Maine, and PhD in Biology from Temple University. You can follow him on Twitter @SteveAuscavitch and via his personal website. |

Jacob Jaskiel (he/him/his) is a 5th year PhD candidate studying early life history and population dynamics of tropical tunas across the Pacific. He graduated from BU (’19) majoring in Marine Science and minoring in Environmental Analysis and Policy. Jacob went to sea with the Sea Education Association in 2018, where he helped the crew collect the oceanographic data and plankton samples that we analyze in the lab (check out the blog on NatGeo Open Explorer!). In the lab, he works with ichthyoplankton samples from throughout the Pacific in order to gather information that may inform future conservation efforts, in collaboration with Jan Witting at SEA. He also co-authored a recent paper on seagrass microplastics. Fun fact from Jacob: I am a huge outdoorsman and I love to kayak, fish, snorkel, camp, and pretty much anything else that allows me to be in nature. @RascalJaskiel Goo |

Caroline Fleming (she/her/hers) is a 5th year PhD candidate and #NSFGRFP 2020 Award Winner. In her undergraduate career at College of the Holy Cross, she worked with Dr. Justin McAlister investigating the phenotypic plasticity of Lytechinus variegatus sea urchin larvae under various feeding regimes. At BU, she is interested in quantifying the energetic trade-offs corals make under anthropogenic stressors. To this end, Caroline draws from the disciplines of mathematical modeling, larval ecology, ecological toxicology, and energetic physiology to understand how marine organisms are adapting to a changing oceanic system. Caroline is also a member of the URBAN Biogeoscience and Environmental Health program at BU, where she investigates the effect of urban nutrification on the physiology of the temperate coral Astrangia poculata in Narragansett Bay, Rhode Island. An ecophysiologist at heart, Caroline has dipped her toes in population ecology, phylogeography, and epigenetics, but has found her home in the multidisciplinary work of the Rotjan lab. When not in the lab or riffling through the nearest tide pool, you can find Caroline putting her Art History minor to work at a Boston art museum, or attending an indie rock concert. @cflemsscientist |
