Despite being invisible to our naked eyes, bacteria are instrumental to sustaining human and global health, having roles that range from bolstering our immune defenses to recycling carbon and energy worldwide. I am intrigued by the way marine bacteria govern the movement and distribution of nutrients throughout the ocean basins via their interactions with dissolved organic matter (DOM); I am interested to know the extent to which these microscopic interactions between bacteria and DOM influence both regional and global carbon cycling and sequestration.
My research interest lies at the interaction between marine microbial processes and ocean carbon biogeochemistry. I am specifically interested in the role of increased partial pressure of carbon dioxide on microbial processes and selection of its community structure.
I am mostly interested in the research about microbial degradation and transformation of DOM in seawater. During my Ph.D., I used small peptides as model compounds to investigate mechanisms of DOM decomposition and its role in the marine carbon and nitrogen cycles. I developed a new High Performance Liquid Chromatography-Mass Spectrometry method to measure low-concentrations of small peptides in seawater, compared peptide hydrolysis and/or decomposition rates and pathways in different seawater environments such as oxic vs.
My research as a PhD student focused on the production and fate of organic carbon in the context of nitrate supply for the California Current System. My current research, as a participant in NASA's EXPORTS program, involves the quantification of organic matter removal rates by microbes in order to provide a constraint on one of the (many!) potential fates of carbon produced in the surface ocean.
I am currently an Associate Specialist, responsible for curating DOM and microbial datasets, overseeing day-to-day operations in the lab, and facilitating fieldwork on the variety of projects ongoing in our lab group.
I am a sea-going technician responsible for the collection and analysis of dissolved organic matter from a number of coastal and open ocean sites, including participation in the US CLIVAR Repeat Hydrography Program.
