Short Bio (CV)

I am an Associate Professor in the Department of Computer Science and Engineering at University at Buffalo, SUNY. Previously, I was an Associate Professor in the School of Computing and the Director of Cybersecurity Center at Clemson University. I am a recipient of the NSF CAREER Award for 2019. My research spans security, networking, and machine learning. Given the interdisciplinary nature of my work, I have published across a wide range of well-recognized conferences, including security (CCS, USENIX Security, NDSS, ACSAC, and ASIACCS), networking (SIGCOMM, INFOCOM, ICNP, and IWQoS), machine learning (ICML), human-computer interaction (CHI and CSCW), and computer science education (SIGCSE). My research has been funded by NSF (SaTC, CNS, IIS, OAC, SOC, and DGE), USDOT, VMware, Google, Amazon, Dell, etc. I am the recipient of the Best Paper Awards from ACSAC 2020, IEEE ICC 2020, ACM SIGCSE 2018, and ACM CODASPY 2014, and the Best Paper Award Honorable Mentions from ACM SACMAT 2016, IEEE ICNP 2015, and ACM SACMAT 2011. My research has won the First Place Award in ACM SIGCOMM 2018 SRC. My research has also been featured by the IEEE Special Technical Community on Social Networking and received wide press coverage including ACM TechNews, InformationWeek, Slashdot, NetworkWorld, etc.
