About
My research aims to provide a comprehensive framework for high-performance data management, critical in extracting meaningful insights from large and complex computational systems. Broadly, I have an interest in developing scalable algorithms and data structures that can inject interactivity and performance into data- and compute-intensive applications. My core expertise is HPC, but my overall research relies on the effective use of techniques from a range of areas including databases, topology, visualization, and machine learning.
As an undergraduate at DAIICT, I was fascinated by computer graphics, ultimately leading me to join The University of Utah. While at the U, I spent a summer at Argonne National Lab, where I was exposed to the world of supercomputing. I was thrilled by the idea of using supercomputers to solve computationally massive problems. Ever since, I have worked at the intersection of HPC, analytics, and visualization, helping domain scientists extract knowledge from massive amounts of complex data.
