Experience
Principal Scientist
Apr 2019 — Present
I support clients by solving technical problems involving chemistry, electrochemistry, materials science, and battery science. I am trained in inorganic chemistry, and I specialize in electrochemistry and surface chemistry which enables me to provide chemistry-based solutions to many industries such as mining, transportation, and consumer electronics. I have conducted performance and failure analyses on many products and devices including primary and rechargeable batteries (i.e, lithium-ion, lead-acid, NiMH, LiSOCl2, thin film), consumer electronic devices, coatings, medical devices and various electrical components. In the field of batteries and energy storage, I am skilled at performing performance and accelerated life testing, cell design and materials evaluation, technical IP analysis, litigation support, and technology evaluation. I have extensive expertise in applying non-destructive analysis techniques, notably high-resolution computed tomography X-ray (CT) scanning, to solve various technical problems related to manufacturing processes, corrosion, mechanical wear and intricate electronics analysis. I have extensive experience in a variety of electrochemical [voltammetry, impedance, Quartz-Crystal Microgravimetry (QCM)] and photoelectrochemical methods [photocurrent, efficiency (IPCE)]. I am also skilled in many materials characterization techniques for structure and composition such as surface profilometry, electron microscopy (TEM/ED and SEM/EDS), X-ray [diffraction, spectroscopy, computed tomography (CT)], N2 Adsorption (BET), Thermogravimetric Analysis (TGA), Accelerating Rate Calorimetry (ARC), and various spectroscopy techniques (UV-vis, IR, Auger, and Raman).
