About

Dr. Alex Jahya is a leading researcher in the mechanics of needle-tissue interaction, a field critical to advancing minimally invasive medical procedures and robotic-assisted surgery. His work focuses on understanding the fundamental forces that arise during needle insertion—specifically, the cutting force at the needle tip and the frictional force along the shaft—to improve precision and control. Dr. Jahya’s most cited paper, “Mechanics of needle-tissue interaction” (2011), with 76 citations, provides foundational insights into these forces, offering a framework for optimizing needle design and steering. He further advanced the field through finite-element (FE) modeling of bevel-tipped needles (2015), demonstrating how computational analysis can predict needle deviation and enhance robotic steering systems. By quantifying the interplay between tissue deformation and needle behavior, Dr. Jahya’s work has direct implications for reducing tissue trauma and improving targeting accuracy in biopsies and drug delivery. His contributions are essential for researchers and engineers developing smart, steerable needles, making him a key figure in the intersection of biomechanics and medical robotics.
