I am a Postdoctoral Researcher at the University of Texas, San Antonio, specializing in geometric intersection and approximate nearest neighbor similarity search within expansive geospatial polygonal datasets. Proficient in parallel and distributed computing, high-performance computing, GPU programming, and spatiotemporal data processing, my research focuses on exploiting parallel computing in heterogeneous and distributed platforms to enhance the performance and scalability of polygonal operations. My expertise lies in architecting efficient data structures and algorithms for multi-core and many-core systems, contributing nuanced insights at the confluence of computer science and geospatial data, addressing intricacies in geometric computations on large datasets.
