Marc-Olivier completed his B.Sc in ecology in a problem-based learning program at l’Université du Québec à Montréal. He studied, as an undergraduate with Denis Réale and Anne Charmantier, population genetics of blue tit (Cyanistes cæruleus) birds in Corsica. He is interested in ecology, evolutionary biology and the intrigue of biological diversity on this planet. Multidisciplinary approaches are his hobby horse, and he tries trying to combine scientific popularization, knowledge transfer, and a bit of art. His Ph.D. thesis will utilize population genomic methods to understand the evolution of Darwin’s finches.

Victoria earned her B.Sc. in Environmental Sciences from the University of California, Berkeley, minoring in Science and Math Education (CalTeach). As an undergraduate, she worked with Dr. Jamie Cate (UC Berkeley) using CRISPR-Cas9 to: genetically engineer yeast for specialized fatty-acid production, and reduce wheat and rice’s susceptibility to bacterial and fungal pathogens. Her honors thesis under Dr. Claire Kremen (UC Berkeley) studied how passerine and near-passerine birds in California’s Central Coast are impacted by agricultural land use change; this was achieved by linking haematological metrics and aerial imagery via mixed-effects modeling. Victoria is also passionate about STEM outreach. With the CalTeach program she designed culturally-relevant science curriculum and taught over 200 hours in K-12 classrooms in the East Bay. For her Ph.D. she is interested in exploring coral’s molecular responses to climate change. Victoria is part of the NEO-STRI Program and is being co-advised by Dr. David Kline (STRI).

Marcus completed his BSc in Ecology, Evolution, and Behavior at the University of California Los Angeles. As an undergraduate, he worked with Dr. Tina Treude, Dr. David Jacobs, and Dr. Jeana Drake studying ocean geochemical cycles of nitrogen, coastal lagoon geomorphology, and stony coral biomineralization proteomics. Afterwards, Marcus worked with Dr. Sergey Nuzhdin at the University of Southern California, researching giant kelp (Macrocystis pyrifera) genetics and aquaculture. For his Master’s thesis (co-advised by Dr. Nagissa Mahmoudi), Marcus is interested in examining the genetics and microbial associations of local seaweed species under changing environments.

Alina is an undergraduate student at McGill University entering her third year in the Joint
Honours Computer Science and Biology program. Alina recently attended a biology course held at McGill’s Bellairs Research institute in Holetown, Barbados. There, she pursued her interests in tropical biology by exploring size frequency distributions of coral species as a measure of coral reef health. Alina was also awarded a Summer Undergraduate Research in Engineering experience in collaboration with the Biofluids and Global Health Lab, lead by Dr. Caroline Wagner, pursuing research in infectious disease modeling and containment strategies. Continuing to explore her research interests, Alina will work with Ph. D student Victoria Glynn on her research in conducting heat stress experiments with sea anemones.

Andrew Kemp graduated from his Bachelor of Science in Honours Biology at McGill University in spring of 2024. He is broadly interested in evolutionary ecology, recently finishing his Honours Thesis with PhD student Lucas Eckert on morphological adaptations of stickleback along the benthic-limnetic axis in response to their environment, both in situ and in common garden. He has also done work on at-risk plants, peat soil, and biochar applications. His experiences have fostered his passion for researching climate change’s impacts on the environment and communities. The summer following his undergrad, he will be doing research using machine learning models trained on climatic datasets to help predict vulnerabilities and mitigate the effects of climate change in the Caribbean. He plans to pursue his interests through graduate studies.

Eva is an undergraduate student at McGill University, entering her final year in the Honours Biology program. She works as a volunteer in Dr. Barrett’s lab, assisting MK Hickox with extracting DNA from stickleback samples collected in California to study the processes of natural selection within and across populations. While working in the lab, she practiced various molecular techniques, such as DNA extractions, quantifications, or Speevac
