Illuminating evolution one compartment at a time. Pioneering spatial proteomics approaches in photosynthetic microeukaryotes at Harvard University, the Scripps Institution of Oceanography, and the J. Craig Venter Institute (JCVI).

On Sep 1, 2016, I became a Visiting Graduate Student in Prof. Andrew E. Allen Lab at the Scripps Institution of Oceanography (SIO) and the J. Craig Venter Institute (JCVI) where I am continuing my spatial proteomics work in diatoms. My new mailing address is as follows:

I am a marine microbiology Ph.D. Candidate at Harvard University working in the laboratory of Pamela Silver. Fascinated by the microbial diversity of the oceans, I am striving to push the nascent field forward by developing molecular tools to study diatoms, highly abundant and evolutionarily successful photosynthetic unicellular algae with intricately ornamented species-specific silica cell walls. I am interested in understanding the molecular mechanisms guiding the morphogenesis of diatom cell walls and more specifically in the role polyamines play in this process. Biological problems surrounding diatom cell wall biogenesis lead me to my broader research questions:  how have mineral skeletons in ocean microorganisms and biomineralization as a biological phenomenon in general evolved,  what is the molecular basis of biosynthesis of such biominerals and other intricately patterned naturally occurring biomaterials and  how is polyamine metabolism regulated across kingdoms.

- Spatial biosilicification-specific proteomics in the model diatom Thalassiosira pseudonana.
Figure 1 | Overview of the biosilicification process in diatoms. (Left) Diatom cell wall is synthesized inside an acidic compartment called the silica deposition vesicle (SDV). (Right) It is hypothesized that the interaction of silaffins with long-chain polyamines (LCPA) inside the SDV leads to the formation of an organic matrix, the structure of which is controlled by the silaffins (adapted from Kröger, 2007, and Kröger & Poulsen, 2008).

My work is supported by the Gordon and Betty Moore Foundation: "The Gordon and Betty Moore Foundation believes in bold ideas that create enduring impact in the areas of science, environmental conservation and patient care. Intel co-founder Gordon and his wife Betty established the foundation to create positive change around the world and at home in the San Francisco Bay Area. Science looks for opportunities to transform–or even create–entire fields by investing in early-stage research, emerging fields and top research scientists. Environmental conservation efforts promote sustainability, protect critical ecological systems and align conservation needs with human development. Patient care focuses on eliminating preventable harms and unnecessary healthcare costs through meaningful engagement of patients and their families in a supportive, redesigned healthcare system."

- Biochemistry Bootcamp Mentor, Wellesley College, Wellesley, MA, January 2015
I served as a mentor for the inaugural biochemistry bootcamp aimed at promising undergraduates at Wellesley College. Students expressed a protein in bacteria, purified it, assayed its activity, and presented their findings to their classmates. I directly supervised a pair of undergraduate participants. The administrators at Wellesley agreed to offer this bootcamp opportunity to students again in 2016.
