Dr. Batara has an interdisciplinary background in chemistry, physics and materials science with 5 years of experience modeling and characterizing photo-electrochemical semiconductor systems. His expertise includes: solid-state physics, nanophotonics, computational mathematics, software development and systems administration.
Dr. Batara completed is Ph.D. in Materials Science at the California Institute of Technology in the Solar Fuels and Light-Matter Interactions Groups with Professors Nathan S. Lewis and Harry A. Atwater. There he developed computational simulation and analysis software tools for applications in nanophotonics and photo-electrochemical deposition of semiconductors. Additionally, he gained hands on experience with characterization techniques such as (cryogenic) ellipsometry, scatterometry, integrating sphere, atomic force microscopy (AFM) and optoelectronic materials characterization.
As a software developer, Dr. Batara is proficient with MATLAB and has experience with Python, and Java. Prior to joining Exponent, he worked in the technology startup environment as a big-data software developer. Additionally, he served as internal software & IT consultant and systems administrator for the above research groups at the California Institute of Technology.
Prior to his doctoral studies, Dr. Batara worked in two research laboratories at the University of California Santa Barbara while completing his B.S. in Chemistry and Physics Minor. He worked on the isolation and characterization of iron chelating compounds produced by marine bacteria via high pressure liquid chromatography, amino acid sequencing and mass spectrometry. Additionally, he worked on the synthesis and characterization of materials for organic photovoltaic applications via macroscale organic synthesis techniques, nuclear magnetic resonance imaging (NMR) and dynamic light scattering (DLS). He also worked on the device fabrication and testing of organic photovoltaic devices with techniques such as spin coating, vacuum evaporation and current-voltage measurements.
