Florian Suri-Payer

PhD Candidate, Cornell University




I am a fifth year CS PhD student at Cornell University where I am fortunate to be advised by Lorenzo Alvisiand Natacha Crooks(UC Berkeley). Prior to grad school I completed my undergrad in CS at TU Berlin, Germany. Outside research, I am an avid tennis player and member of the Cornell Club Tennis team.


My passion lies in analytical thinking and formal rigor as applied to computing systems. My research addresses the design of large scale distributed systems, specifically efficient Byzantine fault tolerance, transaction processing and wide area replication. I am also broadly interested in the use of Machine Learning to support distributed systems, and vice versa. I aim to pursue principled, foundational research that can actually be realized and deployed.

My current research focuses on building robust and efficient transactional systems that provide strong consistency and expressive application interfaces. More concretely, my ongoing thesis research attempts to introudce new approaches towards delivering highly peformant Byzantine Fault Tolerant (BFT) Database Systems. Broadly, my work spans the construction of low latency and high throughput distributed transactional systems, and the design of low-latency BFT consensus algorithms that achieve high degrees of parallelism and decentralization.
