My research is in the area of high-performance data science in support of the DOE mission in
computational and experimental science. Overwhelmed by the rapid growth in data size,
complexity and diversity, application sciences today are looking towards data sciences
for end-to-end data solutions for analysis, management, knowledge-discovery, and sharing
of data throughout the project and data life-cycle. Ultimately the goal of my research is
to enable science teams to effectively utilize their data to gain new scientific insights
not possible otherwise. I envision a future in which researchers will be able to seamlessly
integrate and utilize data from multiple user facilities, online data archives, simulations,
and other sources to seamlessly create complex, next- generation data-driven experiments in
familiar, unified analysis and collaboration environments. Users will be able to discover
new knowledge and detailed understanding of complex natural systems through the ability to
investigate structure and dynamics across temporal and spatial scales guided by smart
visualization and analysis solutions.
To address these challenges, my research to date has focused on the intersection of visualization,
machine learning, and data management for large-scale and high-dimensional data, with a particular
focus on (a) machine learning, visualization, and analytics algorithms and methods for large-scale,
high-dimensional, and multi-modal data, (b) data modeling and management for efficient data sharing
and integration, and (c) data and analysis systems to enable data sharing, reuse, and analysis.
My research interests more broadly are in the areas of: 1) FAIR data science, 2) machine learning
and feature detection, 3) computational topological, 4) high-performance computing,
5) scientific/information visualization, 6) data management and I/O,
7) bioinformatics, 8) end-to-end data systems, 9) data analysis solutions for applications in
bioscience (e.g., biomaging and neuroscience), high-energy physics
(e.g, particle accelerator modeling), climate and others.
