My Research

My lifelong passion for building intelligent computer systems—sparked by a childhood fascination with technology—has guided me through diverse areas including distributed systems, mission-critical enterprise software, and large-scale data analytics. Over time, I’ve become deeply focused on high-performance computing (HPC) and the potential it holds for solving grand challenges, especially in the post-Moore’s law era. This journey has led me to explore machine learning, sustainable supercomputing, and data-driven modeling, all aimed at making powerful systems more efficient, reliable, and environmentally responsible.

Today, my research focuses on applying HPC operational analytics and advanced modeling to optimize exascale environments. I work closely with domain scientists at HPC sites, industry partners, and academic research groups worldwide, integrating data-driven methods into real-world impact. By translating fundamental research insights into practical solutions, I help tackle key issues like energy efficiency, performance tuning, and infrastructure reliability.

I’m excited about bridging the gap between cutting-edge HPC theory and industrial-scale deployment, envisioning a future where sustainable, high-performance computing ecosystems not only drive scientific breakthroughs but also benefit society at large.
