I am joining the CS department at the University of Texas at Dallas in Fall 2025.
I am joining the CS department at the University of Texas at Dallas in Fall 2025.
I am an incoming Assistant Professor in the Department of Computer Science at the University of Texas at Dallas (Fall 2025). Currently, I am a Postdoctoral Researcher in the Department of Computer Science at Purdue University. I completed my Ph.D. from the same department in Spring 2023 under the supervision of Prof. Elisa Bertino.
I lead the System and Network Security (SysNetS) lab at UTD. My research interests lie in the general area of systems and network security. More specifically, my focus is on ensuring the security and privacy of wireless communication protocols (e.g., cellular networks-4G/5G, Bluetooth, VoWiFi, vehicular, WiFi, and IoT) with respect to their design and implementation. My research aim is to develop tools that systematically analyze real-world systems and widely used protocols using formal verification, program analysis, machine learning, natural language processing, and software testing techniques. Furthermore, with the advent of the next generation of networks (6G and beyond), my future goal is to ensure the resilience (reliability, adaptability, and security) of future network generations and develop protocols and systems that are robust and secure by design.
My Research Pitch:
My research focuses on the following themes:
Formal analysis of protocol standards
5GReasoner [CCS 2019], VWAnalazyer [AsiaCCS 2022],
WiFi Verification [AsiaCCS 2024], Vehicular [VehicleSec 2024]
LLM-based protocol analysis
SPEC5G [AACL 2023], CellularLint [Usenix Sec 2024]
Protocol noncompliance checking
BLEDiff [IEEE S&P 2023], DIKEUE [CCS 2021]
Systematic implementation analysis
ProChecker[ICDCS 2021], ATFuzzer [ACSAC 2019]
Secure protocol design and defense
FBSDetector [Usenix Sec 2025A], AKMA+ [Usenix Sec 2025B],
TIMESAFE [arXiv 2024]
My research has led to several changes in the design of 4G and 5G cellular standards. Also, I have found numerous security and privacy issues in various protocols and system implementations. Due to this, I have been inducted into the GSMA Mobile Security Research Hall of Fame three times, received acknowledgments from the WiFi Alliance and received numerous bug bounties, CVDs, and CVEs. I received the Best Paper award at ACSAC 2019 and the Best Paper award nomination at ICDCS 2021. For outstanding security research, I received the Maurice H. Halstead Memorial Award and the Bilsland Dissertation Fellowship Award from Purdue University in 2020 and 2022, respectively.
I got the opportunity to work as an Applied Scientist Intern at Amazon (Summer 2021) and a Security Researcher Intern at Intel (Summer 2020, 2019).
I completed my B.Sc. from the Department of Computer Science and Engineering, Bangladesh University of Engineering and Technology, in September 2017.
