I am a research scientist at Sandia National Laboratories. My research interests include computational geometry (sampling methods and Voronoi tessellations), Uncertainty Quantification and Optimization. From my 50+ publications, I mostly proud of VoroCrust, an algorithm that I developed to solve the Voronoi meshing problem.
I am also the founder of, Itkan Institute of Technology, a non-profit organization that aims to inspire kids of underserved, under-represented communities, esp. Muslims, to learn more about Science, Technology, Engineering and Math (STEM) at a young age. Itkan Institute of Technology is the home of several FTC teams in the United states under the name of The Marvels.
