Dr. Urban utilizes his knowledge and experience with electronic system design, application, and implementation to assist clients with a wide variety of projects. Dr. Urban has performed numerous proactive design reviews as well as reactive failure analyses for consumer and commercial products. His work often includes design reviews, forced failure analyses, and/or engineering analysis of electrical systems. Dr. Urban also has experience with automotive electronics, power quality studies, code and standard reviews, and control system design. Dr. Urban has performed several source code reviews and has expertise with simulation, experimental control, and data analysis/visualization in Python as well as familiarity with both C, MatLAB, and LabView. Dr. Urban’s projects have further involved investigations related to fires and explosions, industrial accidents, electrocutions/shock injuries, and control system failures.

Dr. Erik Urban has an extensive background in atomic physics, with expertise in the control and measurement of trapped ions and in the development of related hardware and experimental systems. This experience includes knowledge of radio-frequency electronics, printed circuit board (PCB) debugging and design, electrostatic field simulations, optical lasers, and ultra-high vacuum systems.

Prior to joining Exponent, Dr. Urban obtained his Ph.D. from the University of California, Berkeley as a National Science Foundation Graduate Research Fellow in the field of experimental atomic physics. His research included design, implementation, and characterization of novel ion traps for the study of fundamental quantum interactions and new quantum controls to aid in the development of quantum technologies.

Dr. Urban’s doctoral work required the use of visible lasers/optics systems, ultra-high vacuum components, and both radio-frequency (RF) and DC electronics. Specifically, frequency-locked lasers manipulate the internal state of the atom, RF electronics control the laser frequency at a given time and generate electric fields to trap the charged particles, and DC electronics control both the sub-microsecond timing of the experiment and the fields experienced by the ions. He also designed electrostatic simulations to model atom dynamics and implemented the results to manipulate their motion.
