I am an Assistant Professor in the Computer Science Department at Carnegie Mellon University, with a courtesy appointment in the ECE department. I lead the TheSys research group at CMU. I am a part of the Parallel Data Lab (PDL). My research interests lie in the broad area of computer and networked systems with a current focus on data analytics systems and live video streaming. I am interested in the fault tolerance, scalability, and performance challenges that arise in all layers of the big data stack -- storage/caching, distributed computation, networking, and applications.

Research Overview

A bulk of my past research has focussed on the storage/caching layer and in part on the application (specifically, machine learning) layer:

  • Storage/caching: My research focus here has been on fault tolerance, scalability, load balancing, and reducing latency in large-scale distributed data storage and caching systems. We designed coding theory based solutions that we showed are provably optimal. We also built systems and evaluated them on Facebook's data-analytics cluster and on Amazon EC2 showing significant benefits over the state-of-the-art. Our solutions are now a part of Apache Hadoop 3.0 and are also being considered by several companies such as NetApp and Cisco.

  • Machine learning: My research focus here has been on the generalization performance of a class of learning algorithms that are widely used for ranking. We designed an algorithm building on top of Multiple Additive Regression Trees, and through empirical evaluation on real-world datasets showed significant improvement over classification, regression, and ranking tasks. The new algorithm that we proposed is now deployed in production in Microsoft's data-analysis toolbox which powers the Azure Machine Learning product.

TheSys (theory + systems) research group


My research group is called "TheSys (Theory + Systems)" since we take a principled and holistic approach towards solving real-world problems considering both theoretical and systems perspectives. We design solutions rooted in fundamental theory as well as build systems that employ the resulting insights and solutions to advance the state-of-the-art.
