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).
Be part of my efforts to save coral reefs at Let’s all tri our best, TriForOceans!
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:
J. Craig Venter Institute
4120 Capricorn Lane
La Jolla, CA 92037
Email: email@example.com & firstname.lastname@example.org
Molecular and cell biologist with broad international academic and industrial research experience. PhD Candidate in Biological and Biomedical Sciences at Harvard University (expected to graduate in Spring 2019), Visiting Graduate Student at The Scripps Institution of Oceanography, University of California, San Diego, and Research Fellow at J. Craig Venter Institute. iGEM 2010 World Champion and protocols.io ambassador. Open science advocate.
In my PhD thesis I am using a genetically encodable tag for subcellular proteomics to study endocytosis, carbon fixation and biosilicification in diatoms, highly abundant and evolutionarily successful photosynthetic microeukaryotes.
My future interests with tangents to my PhD work are as follows:
1. Continuing my work on systems understanding of the molecular mechanisms guiding the morphogenesis of diatom cell walls. I am particularly interested in polyamines and their role in connecting cell cycle control and call wall formation.
2. Extending my studies on biomineral morphogenesis to non-diatom model systems such as radiolarian protozoa Acantharea which are using strontium sulfate to build their skeletons.
3. Studying evolutionary origins and basic physicochemical principles of protein-induced phase transitions in eukaryotes. I am especially interested in how protein disorder, low amino acid complexity and posttranslational modifications tie to these processes.
4. Investigating antizyme-mediated regulation of polyamine homeostasis and the mechanisms of polyamine-induced ribosomal frameshifting.
I have always been very motivated to balance science with my passion for sports which will extend into all of my future endeavors. I have developed as a triathlete throughout graduate school and am anticipating to participate in my first full Ironman race in 2019.

- 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."

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.
