Joohwa has many years of experience in Analog/RF/Milimeter-wave circuit designs. He was the undergraduate research member in Millimeter Microwave Laboratory at the University of Arizona, where he worked on 5 GHz LNA for WLAN and 3-11 GHz UWB LNA. He joined High-Speed Integrated Circuits Laboratory at UCSD, where he was involved with LEAP/SMART/Elastx DARPA projects. His doctoral study included high-speed analog, RF, and millimeter-wave integrated circuit design for wireless and wired communications. He has held an internship with Oracle, Sun Microsystems Lab, San Diego, where he worked on the high-speed circuits for silicon-based on-chip optical interconnects.
He has authored and co-authored 10 Journal (1st author for 7 papers including 3 JSSC) and 9 conference papers including ISSCC. He received IEEE Circuit and Systems Society Outstanding Young Author Award in 2011. He is now with Qualcomm, San Diego.
He serves as a reviewer for a number of journals, including the IEEE Journal of Solid-State Circuits (JSSC), IEEE Transactions on Circuits and Systems I (TCAS), IEEE Transactions on Microwave Theory and Techniques (T-MTT), and IEEE Microwave and Wireless Components Letters (MWCL).
