About

Parna Niksirat is a researcher whose work lies at the critical intersection of terramechanics and planetary robotics, with a primary focus on how reduced gravity affects wheeled locomotion on soft, deformable terrain. Her most-cited paper, "Effect of gravity in wheel/terrain interaction models" (2019, 16 citations), makes a foundational contribution by systematically analyzing how non-terrestrial gravitational fields alter the forces and torques developed between a rover's wheels and the ground. This work is essential for designing reliable mobility systems for future lunar and Martian exploration missions, where the physics of soil interaction differs dramatically from Earth. By challenging and refining existing wheel-terrain models to account for gravitational variation, Niksirat has provided engineers with more accurate predictive tools for rover performance in unstructured extraterrestrial environments. Her research is particularly valuable for students and engineers working on planetary rovers, as it bridges the gap between classical terramechanics and the unique demands of space exploration, helping to ensure that next-generation robots can traverse alien landscapes safely and effectively.
