Bongmook Lee

Biography

He received his M.S. and Ph.D. in Electrical and Computer Engineering from North Carolina State University. His doctoral work focused on developing advanced high-k/metal gate stacks for next generation CMOS technology. From 2010 to 2012, he was a postdoctoral research associate in the NSF-FREEDM system center. His research interests cover the broad area of materials and device design with current focus on ultra-low power environmental sensors, wide bandgap SiC and GaN power devices, wearable and flexible electronics, biosensors and nonvolatile memory devices. He was recipient of the Applied Materials doctoral Fellowship from 2008 to 2010. He has authored and co-authored more than 75 peer reviewed technical articles and holds 9 invention disclosures and 1 U.S. patent.

His current research interests lie in advanced electronic devices through concepts/materials innovation and a multidisciplinary approach to both enhance already existing device technologies and introduce completely new device application based nano systems. Therefore, the core of my research is based on design and simulation with experimental verification. To explore and push the performance limits of electronics and create novel applications for electronics, my work focuses on two main research areas: (i) Ultra-thin nano sensors for wearable applications, (ii) wearable sensing system and application, and (iii) Wide-bandgap semiconductor materials and devices for next generation power device application.
