Bianca Santos is a PhD candidate in the Emmett Interdisciplinary Program in Environment and Resources, where she studies science and policy as it relates to the spatial management of migratory marine species and resources. Her current work focuses geographically within the Pacific Ocean, where she investigates case studies across scales, from local to international levels. Utilizing both natural and social science tools, her research applies interdisciplinary methods from the fields of marine science, ocean governance and policy, and environmental decision-making. In addition to her research, Bianca is passionate about science communication and outreach.
Prior to Stanford, Bianca served as an International Activities Analyst as a 2018 National Sea Grant Knauss Marine Policy Fellow in NOAA Research’s Office of International Activities. She also worked with the Food and Agriculture Organization of the United Nations to support issues related to spatial marine management.

A path forward for qualitative research on sustainability in the COVID-19 pandemic.
The unique strengths of qualitative research, through in-depth inquiry and identification of unexpected themes and linkages, is essential to our growing understanding of COVID-19's impacts on the social world and its intersection with sustainability science. However, many challenges-physical, psychological, and ethical in nature-face qualitative researchers during the pandemic, as social distancing and travel restrictions prevent in-person field work. In this paper, we outline the essential contributions of qualitative study to sustainability science, discuss current challenges, and in turn, provide recommendations for researchers.

Regulation of apoptosis-related genes during interactions between oyster hemocytes and the alveolate parasite Perkinsus marinus
FISH & SHELLFISH IMMUNOLOGY
2018; 83: 180–89
The alveolate Perkinsus marinus is the most devastating parasite of the eastern oyster Crassostrea virginica. The parasite is readily phagocytosed by oyster hemocytes, but instead of intracellular killing and digestion, P. marinus can survive phagocytosis and divide in host cells. This intracellular parasitism is accompanied by a regulation of host cell apoptosis. This study was designed to gain a better understanding of the molecular mechanisms of apoptosis regulation in oyster hemocytes following exposure to P. marinus. Regulation of apoptosis-related genes in C. virginica, and apoptosis-regulatory genes in P. marinus, were investigated via qPCR to assess the possible pathways involved during these interactions. In vitro experiments were also carried out to evaluate the effect of chemical inhibitors of P. marinus antioxidant processes on hemocyte apoptosis. Results indicate the involvement of the mitochondrial pathway (Bcl-2, anamorsin) of apoptosis in C. virginica exposed to P. marinus. In parallel, the antioxidants peroxiredoxin and superoxide dismutase were regulated in P. marinus exposed to C. virginica hemocytes suggesting that apoptosis regulation in infected oysters may be mediated by anti-oxidative processes. Chemical inhibition of P. marinus superoxide dismutase resulted in a marked increase of reactive oxygen species production and apoptosis in infected hemocytes. The implication of oxygen-dependent apoptosis during P. marinus infection and disease development in C. virginica is discussed.

Transepithelial migration of mucosal hemocytes in Crassostrea virginica and potential role in Perkinsus marinus pathogenesis
JOURNAL OF INVERTEBRATE PATHOLOGY
2018; 153: 122–29
We have recently described the presence of hemocytes associated with mucus covering the pallial organs (mantle, gills, and body wall) 3 of the eastern oyster Crassostrea virginica. These hemocytes, hereby designated "pallial hemocytes" share common general characteristics with circulating hemocytes but also display significant differences particularly in their cell surface epitopes. The specific location of pallial hemocytes as peripheral cells exposed directly to the marine environment confers them a putative sentinel role. The purpose of this study was to gain a better understanding of the source of these pallial hemocytes by evaluating possible exchanges between circulatory and pallial hemocyte populations and whether these exchanges are regulated by pathogen exposure. Bi-directional transepithelial migrations of hemocytes between pallial surfaces and the circulatory system were monitored using standard cell tracking approaches after staining with the vital fluorescent dye carboxyfluorescein diacetate succinimidyl ester (CFSE) in conjunction with fluorescent microscopy and flow cytometry. Results showed bi-directional migration of hemocytes between both compartments and suggest that hemocyte migration from the pallial mucus layer to the circulatory system may occur at a greater rate compared to migration from the circulatory system to the pallial mucus layer, further supporting the role of pallial hemocytes as sentinel cells. Subsequently, the effect of the obligate parasite Perkinsus marinus and the opportunistic pathogen Vibrio alginolyticus on transepithelial migration of oyster hemocytes was investigated. Results showed an increase in hemocyte migration in response to P. marinus exposure. Furthermore, P. marinus cells were acquired by pallial hemocytes before being visible in underlying tissues and the circulatory system suggesting that this parasite could use pallial hemocytes as a vehicle facilitating its access to oyster tissues. These results are discussed in light of new evidence highlighting the role of oyster pallial organs as a portal for the initiation of P. marinus infections in oysters.
