Experience

Lawrence Livermore National Laboratory

Synthetic Biology Postdoctoral Researcher / February, 2021 — February, 2024

I designed and tested the stability of an array of kill switches for biocontainment of agricultural bacteria. My findings contributed to the rational design of stable yet effective containment systems in soil bacteria.

Lawrence Livermore National Laboratory

Staff Research Scientist — Synthetic Biology / February, 2024 — Present

I wrote a successful proposal to design a synthetic extremophile for bio manufacturing of sustainable plastics without the need for sterilization at any stage of the production process.

University of California, Santa Barbara

Graduate Student Researcher, Biomolecular Science & Engineering / September, 2014 — December, 2020

I studied the mechanism of (1) cell binding/adhesion by contact-dependent growth inhibition (CdiA) proteins and (2) how the ionophore toxins that they deliver into neighboring bacteria exploit native membrane proteins to enter the bilayer.
