Laboratory Manager Microanalysis Facility, Stanford Doerr School of Sustainability - Dean's Office
Bio
I am a staff research scientist and lecturer in the Stanford Doerr School of Sustainability. My primary responsibilities include managing both the day-to-day and long-term operations of the Stanford Microchemical Analysis Facility (MAF). I also have an active research program that includes projects in multiple scientific disciplines, and I teach multiple Stanford courses including courses at both the undergraduate- and graduate-levels.
In addition to my position at Stanford, I am the Treasurer of the Microanalysis Society, hold a courtesy faculty position at Oregon State University, and serve as a technical director for the National Nanotechnology Coordinated Infrastructure program.

Heart cockle shells transmit sunlight to photosymbiotic algae using bundled fiber optic cables and condensing lenses.
Nature communications
2024; 15 (1): 9445
Abstract
Many animals convergently evolved photosynthetic symbioses. In bivalves, giant clams (Cardiidae: Tridacninae) gape open to irradiate their symbionts, but heart cockles (Cardiidae: Fraginae) stay closed because sunlight passes through transparent windows in their shells. Here, we show that heart cockles (Corculum cardissa and spp.) use biophotonic adaptations to transmit sunlight for photosynthesis. Heart cockles transmit 11-62% of photosynthetically active radiation (mean = 31%) but only 5-28% of potentially harmful UV radiation (mean = 14%) to their symbionts. Beneath each window, microlenses condense light to penetrate more deeply into the symbiont-rich tissue. Within each window, aragonite forms narrow fibrous prisms perpendicular to the surface. These bundled "fiber optic cables" project images through the shell with a resolution of >100 lines/mm. Parameter sweeps show that the aragonite fibers' size (~1 µm diameter), morphology (long fibers rather than plates), and orientation (along the optical c-axis) transmit more light than many other possible designs. Heart cockle shell windows are thus: (i) the first instance of fiber optic cable bundles in an organism to our knowledge; (ii) a second evolution, with epidermal cells in angiosperm plants, of condensing lenses for photosynthesis; and (iii) a photonic system that efficiently transmits useful light while protecting photosymbionts from UV radiation.

Comparison of temperature and doping dependence of elastoresistivity near a putative nematic quantum critical point.
Nature communications
2022; 13 (1): 1011
Abstract
Strong electronic nematic fluctuations have been discovered near optimal doping for several families of Fe-based superconductors, motivating the search for a possible link between these fluctuations, nematic quantum criticality, and high temperature superconductivity. Here we probe a key prediction of quantum criticality, namely power-law dependence of the associated nematic susceptibility as a function of composition and temperature approaching the compositionally tuned putative quantum critical point. To probe the 'bare' quantum critical point requires suppression of the superconducting state, which we achieve by using large magnetic fields, up to 45 T, while performing elastoresistivity measurements to follow the nematic susceptibility. We performed these measurements for the prototypical electron-doped pnictide, Ba(Fe1-xCox)2As2, over a dense comb of dopings. We find that close to the putative quantum critical point, the elastoresistivity appears to obey power-law behavior as a function of composition over almost a decade of variation in composition. Paradoxically, however, we also find that the temperature dependence for compositions close to the critical value cannot be described by a single power law.
