I published 50+ peer-reviewed articles in prestigious academic journal, and received awards from leading Human Factors association. My work focuses on understanding how drivers use vehicle technology like touchscreen and voice interfaces, and assistance systems like Adaptive Cruise Control, Tesla Autopilot-like systems, and active and passive systems and their potential unintended consequences on driver behavior and road safety. I analyze human factors like attention, inattention, multitasking, trust, complacency, drowsiness, situation awareness and their impact on safety.
