Elisha Sacks works on computational geometry, the branch of computer science that develops algorithms for representing and reasoning about shapes, curves, and spatial relationships. Recent work applies these methods to robot motion planning (computing collision-free paths), 3D printing quality control (detecting shape defects in printed objects), and robust handling of tricky numerical edge cases ('degenerate predicates') in geometric algorithms.
Publication output has been low and uneven over the past decade, with a burst of activity in 2018 followed by sparse, intermittent output, averaging about one paper per year over the last five years.
