“Being a scientist and sailor is too good to be true.” — Roger Revelle

I am a microbial oceanographer dedicated to exploring the intricate ways marine microbial physiology influences organic carbon flux. My research investigates the effects of organic substrate quality on microbial community responses, with a particular emphasis on climate-driven environmental changes such as wildfire smoke deposition. By combining biological, geochemical, genomic, and bio-optical data from fieldwork, laboratory experiments, and remote sensing, I seek to elucidate the ecological connections between microbial groups and their environments and assess how shifts in these interactions impact ocean biogeochemistry.

During my doctoral research at UC Santa Barbara, I studied the temporal and spatial variability of dissolved organic matter (DOM) and its bioavailability during the annual North Atlantic phytoplankton bloom. An impactful experience was leading a student cruise in the Santa Barbara Channel amidst the Thomas Fire, which deepened my interest in wildfire smoke’s effects on ocean ecosystems.

Currently, as a postdoctoral researcher at Oregon State University, I am involved in projects investigating the physiological responses of marine plankton to wildfire-derived ash, diel cycles in phytoplankton optical properties, and validation efforts for NASA’s Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) mission.
