I build data-intensive systems that are more scalable, more robust, and more predictable. I draw from advanced statistical models to deliver practical database solutions to real-world problems. In particular, I adapt concepts and tools from applied statistics, optimization theory, and machine learning.
Barzan Mozafari is a Morris Wellman Assistant Professor of Computer Science and Engineering at the University of Michigan, Ann Arbor, where he leads a research group designing the next generation of scalable databases using advanced statistical models. Prior to that, he was a Postdoctoral Associate at MIT. He earned his Ph.D. in Computer Science from UCLA in 2011. His research career has led to many successful open-source projects, including CliffGuard (the first robust framework for database tuning), DBSeer (the first automated database diagnosis tool), and BlinkDB (the first massively parallel approximate query engine). He has won the National Science Foundation CAREER award, as well as several best paper awards in ACM SIGMOD and EuroSys. He is also a co-founder of DBSeer and a strategic advisor to SnappyData, a company that commercializes the ideas introduced by BlinkDB.
MySQL, the most popular DB in the world, adopts our VATS algorithm as its the default scheduling strategy! Our contention-aware scheduling algorithm, known as Variance-Aware Transaction Scheduling (VATS), is now the default policy in Oracle MySQL too! With this adoption, over 2M+ servers in the world are running VATS! Congratulations to my students, Jiamin Huang and Boyu Tian, for proposing these algorithms! Read our papers in SIGMOD 2017 and EuroSys 2017.
Morris Wellman Faculty Development Assistant Professorship SnappyData Humbled and honored to be named Morris Wellman Faculty Development Assistant Professor. Many thanks to Wellman family for their generosity.
CAREER Award: Designing a Predictable Database - An Overlooked Virtue Database research has mostly focused on improving the raw performance of database systems, while neglecting the predictability of their performance. NSF has funded us to rethink this traditional architecture, and build a new class of databases that guarantee predictability.
Vehicle-aware data management for autonomous cars Testing autonomous vehicles is an extremely involved task, as an enormous amount of data is constantly collected and processed by thousands of sensors. NSF has funded us to design a smart black-box for cars that can use effective data collection strategies for maximizing the likelihood of finding various types of faults!
Big Data Summer Institute in Bio-statistics Funded by National Institutes of Health, we have launched our Big Data Summer Institute, where you can learn about Big Data, statistics and bio-informatics while getting paid! All details and how to apply, can be found here (do NOT email me about this)!
