Research

Welcome to my website !!

I am a Reseach Assitant Professor in the Computer Science Department of Vanderbilt University working in the Scalable Computing Laboratory team.
I obtained my PhD in Computer Science from the University of Illinois at Urbana-Champaign whie holding a research assistanship with the National Center for Supercomputing Applications funded by the Blue Waters project.

My research interests are in the broad area of performance optmization and resiliency for High Performance Computing, Clouds and distributed computing systems and applications. My research focuses on designing new runtime systems (including scheduling policies, I/O middleware, fault tolerance mechanism and resource sharing policies) as well as analyzing and optimizing algorithms.

More recent, I have started working on computational data science in HPC, with a special focus on irregular applications. I am interested in understanding the computational needs of emerging new fields that do not follow the traditional HPC/Cloud models (like neuroscience and bioinformatics). Data-intensive computing and the HPC/Big-Data/Machine Learning convergence are also topics of interest.

For more information about projects I am involved in, my publications and open source tools I have developed, take a look at my Github page.

Feel free to check out my work and if you have any questions, or would like to work together, don't hesitate to contact me.
