Summary of Expertise:

Listed with other top experts in: 

Expert is a recognized expert in testing, modeling, and analysis of radiation effects in microelectronics. His expertise includes displacement damage from neutrons and protons, ionizing radation effects from gammas, electrons and protons, prompt dose rate effects from x-rays and single event effects from protons and heavy ions. He is an expert in radiation effects in bipolar devices and circuits, CMOS microcircuits, MOS power devices and JFETs. He is an internationally known expert in enhanced low dose rate sensitivity (ELDRS) of bipolar linear circuits. He has presented short course lectures on radiation hardness assurance, single event transient effects in linear circuits, ionzing radiation effects in bipolar technologies, and general radiation effects in microcircuits. Expert is an expert in radiation effects testing of microelectronics at radiation facilites including Co-60, electron LINACS, flash x-rays, fast burst nuclear reactors, proton accelerators and heavy ion accelerators. Expert has over 130 refereed journal publications in these areas and has been awarded numerous outstanding paper awards at conferences. He has authored several invited papers and book chapters. Most of his contract work has been for government agencies and system contractors. He is currently the primary hardness assurance consultant to the Defense Supply Center for radiation qualified electronics and provides technical support to the Defense Threat Reduction Agency.
