Elizabeth Liri

Post Doctoral Fellow · Saint Louis University


I graduated with a Ph.D. in Computer Science from the University of California Riverside under the supervision of Prof. K. K. Ramakrishnan. My dissertation focussed on designing energy-efficient protocols for the Internet of Things.

I am currently a Post Doctoral Fellow - Cyber Physical Systems at Saint Louis University, Missouri working in the Computer Science Networking Research Group headed by Prof. Flavio Esposito.

I am a forward-thinking, innovative computer science researcher with a demonstrated history of publishing research in prominent IoT, cloud computing, and networking conferences. I am adept in various network protocols, tools, and control platforms, capable of utilizing the right technologies to provide effective and quality solutions for research challenges. With strong drive and expertise, I excel in transforming concepts into tangible results, adeptly managing projects of varying scales both independently and collaboratively.
