Make Stony Brook DB Great Again
Event Description
CSE 600 Seminar Series | Fall 2025
Abstract: The first part of the presentation focuses on the fundamental role that failures play in the Ph.D. journey, highlighting how they offer invaluable learning experiences to build resilience, critical thinking, and adaptability. Instead of viewing failures as signs of inadequacy, they should be recognized as opportunities to learn, re-evaluate, and develop the persistence needed for success in a high-stakes research environment. In the second part of the presentation, we take a quick look at the evolution of distributed databases research at Stony Brook and then focus on different challenges associated with distributed transaction processing systems functioning in untrustworthy environments. Byzantine Fault-Tolerant (BFT) protocols have recently been extensively used by distributed transaction processing systems to establish consensus on the order of transactions. However, the proliferation of different BFT protocols has made it difficult to navigate the BFT landscape, let alone determine the protocol that best meets application needs. Moreover, as novel applications, modern hardware, and new cloud platforms arise, distributed transaction processing systems need to be designed with full-stack adaptivity in mind. This presentation discusses our vision for a reinforcement learning (RL)-based distributed transaction processing system that adjusts effectively in real time to dynamic fault scenarios and evolving workloads.
Bio: Mohammad Javad Amiri is an Assistant Professor in the Department of Computer Science at Stony Brook University. Before joining Stony Brook, he was a postdoctoral researcher in the Computer and Information Science Department at the University of Pennsylvania. He received his Ph.D. in Computer Science from the University of California, Santa Barbara. His research mainly lies at the intersection of data management and distributed systems, focusing on distributed transaction processing, consensus protocols, and blockchains.
