Dr. Etezadi-Amoli is an electrical engineer experienced in radiofrequency (RF) measurement techniques, image processing, signal processing, and magnetic resonance imaging (MRI) compatibility analysis and testing of medical devices. She has particular expertise in RF safety in MRI, and her doctoral research demonstrated novel applications of RF transmit array technology to minimize MRI-induced heating in implanted device leads. She is skilled in modeling, simulation, and data analysis using Matlab. She has also performed extensive troubleshooting of hardware and firmware in complex systems ranging from MRI scanners to gaming machines.

Dr. Etezadi-Amoli has experience developing and testing device prototypes and navigating the design challenges involved in integrating these prototypes into larger systems. She has designed and performed detailed validation testing of MRI-compatible optically-coupled RF current sensors for safety monitoring and specialized RF coils for low-power visualization of catheters and guidewires in MRI. She is skilled in troubleshooting complex systems, and she has performed extensive troubleshooting of MRI system hardware to improve signal quality and stability. She has also tested firmware in vehicle detector systems and gaming machines for failures and errors. Her M.S. degree was focused on signal and image processing, and she has served as a teaching assistant and instructor in the Electrical Engineering Department at Stanford University.
