About

Dr. Shivakrishna Dasi is a leading researcher in precision motion control for medical robotics, with a specific focus on enhancing the safety and accuracy of surgical systems. His primary research areas include advanced nonlinear control theory, sliding mode control, and the application of piezoelectric actuators in biomedical devices. Dr. Dasi's most notable contribution is his work on the precise control of a surgical ear robot (VTA) driven by a piezoelectric ultrasonic actuator (PUA). In his highly cited 2025 paper, he developed a novel non-singular terminal sliding mode controller integrated with a perturbation viewer. This innovative approach directly addresses the critical challenges of nonlinearity, uncertainties, and external disturbances inherent in PUA systems, ensuring robust and chatter-free motion. With 5 citations in a short period, this work is gaining rapid recognition for its potential to improve the reliability of delicate otologic surgeries. Dr. Dasi’s research is pivotal in bridging the gap between theoretical control advancements and practical, life-saving medical applications, marking him as a rising authority in surgical robotics and mechatronics.
