About


Hi!

While I’m slowly building this site to actually include things, let me give you the executive summary:

I am a research staff scientist at the University of Washington, broadly focusing on developing microscopy tools for analyzing complex materials for energy production and storage. I am currently “chief scientist” in the Ginger Lab where I am in charge of the atomic force microscopy (AFM). I have ~15 years of scanning probe and optical microscopy expertise, from designing microwave probe methods to inventing entirely new analysis techniques. I have written many reviews, and I recently presented an extensive summary on this subject.

Prior to this, I was an “Optical Microscopy Tool Development Engineer” at Intel, where I specialized in developing next-generation microscopy systems for failure analysis/fault isolation on the 14 nm and 10 nm nodes. My chief accomplishments include a patent on a visible light probing system for subsurface semiconductor analysis, near-field scanning optical microscopy of an active processor test chip, and using super-resolution microscopy to improve optical debug.

I currently focus on applying microscopy research in two areas (more info under “Research” whenever I get to it):

  1. Photovoltaics: I am studying perovskite solar cells using novel AFM methods with an emphasis on “big data” microscopy analysis. I am particularly interested in measuring how these materials can be improved by analyzing how they respond to light at the nanoscale. An example is using the AFM to measure how quickly charge is generated as a function of how polycrystalline the material happes to be.
  2. Mixed ionic/electronic conductors: I am studying how conducting polymers can be used in cutting-edge bioelectronic sensors. These materials use ions (charged atoms) to dope the film. This research includes a high-profile demonstration using AFM to directly image how nanoscale structure impacts ion transport. These studies are naturally related to battery and energy storage (as those are ion conductors).

My academic background (more info under “CV,” again whenever I get to it):

I received my B.S in Electrical Engineering from UT-Austin, where I graduated with high honors. I then received my M.S. and Ph.D. at Rice University working for Prof. Kevin F. Kelly I focused on atomic-resolution microscopy of polymer nanowires. While in graduate school I was the fortunate recipient of an NSF Graduate Research Fellowship and several University-wide awards. I was then a post-doc at the University of Washington before spending several years at Intel.
