About

Sahar Badri is a researcher in computational geometry and discrete mathematics, with a focus on visibility problems in grid-based environments. Her most notable contribution is the development of an optimal algorithm for geodesic mutual visibility on hexagonal grids, a problem with applications in robotics, sensor networks, and computer graphics. This work, published in 2024 and already garnering 2 citations, addresses the challenge of ensuring that multiple agents or sensors can see each other along shortest paths in hexagonal tiling—a structure that better approximates natural movement than traditional square grids. Badri’s algorithm provides a provably optimal solution, balancing efficiency and correctness, which is critical for real-time systems. Her research advances the understanding of visibility in non-Euclidean spaces and offers practical tools for coordinating autonomous systems. With a growing citation record, Badri is establishing herself as a rising voice in algorithmic geometry, and her work is likely to influence further studies in multi-agent path planning and spatial reasoning.
