Dr. Katz has deep experience in thermal characterization and electrical engineering. He has substantial expertise in micro- and nanoscale device fabrication in a cleanroom environment, including cleaning, thin film deposition, lithography, and etching. He also has extensive knowledge of characterization tools including scanning electron microscopy (SEM), atomic force microscopy (AFM), and electrical instrumentation such as lock-in amplifiers. His prior work was primarily motivated by chip-level electronics packaging needs.
Dr. Katz completed his Ph.D. at Stanford University, where his research efforts were focused on thermal characterization of polymer thin films and nanoporous metals. He developed novel fabrication techniques for the patterning of sub-micron features on chemically- and thermally-sensitive samples, facilitating thermal characterization of unique synthetic polymers. He also developed a novel synthesis method for the preparation of nanoporous metal films, with applications for electrochemical systems and sensors.
Dr. Katz has worked with a wide variety of electrical and thermal design and analysis tools including Eagle for schematic capture and layout for printed circuit boards (PCBs), L-Edit for photolithography mask layout, COMSOL for conduction finite element analysis (FEA), C/Arduino for embedded microcontroller development, and MATLAB for numerous tasks ranging from laboratory measurement automation to data analysis using machine learning.
