I am an Associate Professor in the Computer Science and Engineering Department at Lehigh University where I lead the SSS - Scalable Systems Software Research Group.
My research focuses on different aspects of concurrency, synchronization, transactional memory, data structures, distributed computing, hererogeneous systems, in-memory key-value stores, fault tolerance, and distributed systems, spanning from theory to practice. I am passionate about designing and implementing synchronization protocols optimized for a wide range of deployments, from multicore architectures to cluster-scale and geo-distributed infrastructures.

Research Group -- Spring 2022
I am always looking for motivated students who are enthusiastic about theory and practice of concurrency, synchronization, distributed systems, and/or any topic that falls into my areas of interest (see Research).
