I am an Associate Professor in Computer Engineering at San Jose State University. Before joining this department in August 2013, I was a postdoctoral researcher at the University of Illinois at Urbana-Champaign in 2013 and at Columbia University in New York City in 2011. I received my Ph.D. in Computer Science from North Carolina State University in 2010. I worked at the National Security Research Institute at ETRI in Korea in 2003. I obtained an award of excellence as a distinguished faculty mentor for the SJSU Student Research Competition in 2017. I was selected for the Kordestani Endowed Chair in the College of Engineering in 2016 and 2017 as a distinguished research professor. I also received the Faculty Award for Excellence in Scholarship in the College of Engineering at SJSU in 2018. I am the President and Founder of SVCSI (Silicon Valley Cybersecurity Institute), a non-profit organization in Silicon Valley. I was a visiting professor at IBM Almaden Research starting from July 2019 to August 2020 and I was Vice-chair of IEEE Computer Society, Santa Clara Valley Chapter for one year in 2021. My primary research interests are in network and system security. My research has been funded by many local industries and the National Science Foundation (NSF).
