Dr. Katz has deep experience in component and PCB electrical failure analysis and reliability assessment. At Exponent, Dr. Katz supports clients in analyzing failures of biomedical devices, consumer electronics, and other electronics. He leads accelerated lifetime testing of safety-critical systems and provides guidance to clients considering mitigation strategies for critical, time-sensitive failure modes. He is also experienced in performing risk assessments for ethylene oxide sterilization of electronics.

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, primarily motivated by chip-level electronics packaging needs. He developed novel fabrication techniques for patterning sub-micron features on chemically- and thermally-sensitive samples, facilitating thermal characterization of unique synthetic polymers. His research involved substantial work in micro- and nanoscale device fabrication in a cleanroom environment, including cleaning, thin film deposition, lithography, and etching. 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 and KiCad 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. 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.
