About
I am an Associate Professor in the Department of Computer Science at Purdue University and co-director of the Purdue Security Laboratory (PurSec Lab). I am also affiliated with the Center for Education and Research in Information Assurance and Security (CERIAS), where I aim to broaden interdisciplinary collaboration in security and privacy. I earned my Ph.D. in Computer Science and Engineering from Penn State University, where I was advised by Professor Patrick McDaniel and served as the lead graduate student in the Systems and Internet Infrastructure Security Laboratory (SIIS).
My research investigates the design and evaluation of security and privacy for software and systems, particularly within emerging computing platforms and their complex physical environments. To achieve this, my group architects and prototypes system platforms that apply techniques from program analysis, hybrid modeling, formal methods, and artificial intelligence in both cyber and physical domains. Our research approach is best illustrated in enterprise networks, robots, self-driving cars, industrial control systems, and mobile systems, such as smartphones and wearables (e.g., smartwatches, AR/VR headsets). To learn more about our research, you can explore our publications.
My research group actively publishes at top security conferences (USENIX Security, Oakland, CCS, and NDSS). Our work has been sponsored by NSF, ONR, DARPA, USDOT, DOE, the United States Military Academy, Google, Apple, Cisco, Rolls Royce, Denso North America Foundation, and Sandia National Laboratories. I am part of the NSF AI Institute ACTION, DARPA FIREFLY, and USDOT National Center TraCR.
I have received multiple awards, including the NSF CAREER Award (2022), the Google Aspire Award (2021, 2022, and 2023), the Amazon Research Award (2024), and the Google Academic Research Award (2025); paper awards such as the ACM CCS Distinguished Paper Award (2024), the USENIX Security Honorable Mention Paper Award (2025), and the Andreas Pfitzmann Best Paper Award at Privacy Enhancing Technologies (PoPETs) (2026); and university recognition such as the Most Influential Professor Award from the Purdue CS Graduate Student Board (2020 and 2024) and the College of Science Faculty Leadership Award (2024).
I contribute to the research community through various service roles. Currently, I serve as the Secretary/Treasurer of the ACM Special Interest Group on Security, Audit and Control (SIGSAC), as an Associate Editor of IEEE Transactions on Information Forensics and Security (TIFS), and as a co-moderator for cs.CR, the Cryptography and Security subject area on arXiv.

Teaching
CS 426: Computer Security (Undergraduate)
This introductory undergraduate course covers the principles of building secure computer systems and the basics of security best practices. It spans cryptography, network security, systems security, and privacy. Students leave with practical skills for understanding threats and designing more secure software, protocols, and systems.
CS 590: IoT/CPS Security (Graduate)
This graduate course surveys current research on securing Internet of Things and Cyber-Physical Systems. It introduces the foundations of safety and security, along with methods for verification, detection, and repair. Example topics include voice-controlled devices, edge computing, industrial control systems, and autonomous vehicles.
CS 529: Security Analytics (Graduate)
This graduate course explores the intersection of security and machine learning. It is organized into two parts: machine learning for security and the security of machine learning systems. Students build the background needed to study both attacks and defenses across learning and inference.
