I am on the job market for fall 2025. Looking for tenure-track faculty or industry researcher positions!

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 Professor Elisa Bertino.

My research interests lie in the general area of systems and network security. More specifically, my focus is on analyzing 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 systems that are robust and secure by design.

My research focuses on the following themes:

[AACL 2023] [Usenix Sec 2024]

[IEEE S&P 2023] [CCS 2021]

[ICDCS 2021] [ACSAC 2019]

[CCS 2019] [AsiaCCS 2022] [AsiaCCS 2024] [VehicleSec 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.
