About
Mark Sagar is a pioneering researcher whose work spans the frontiers of robotics, virtual reality, and artificial intelligence, with a particular focus on surgical simulation and human-machine interaction. His early career was defined by groundbreaking contributions to microsurgery, where he developed the first teleoperated microsurgical robot for eye surgery (MSR-1), accompanied by a detailed 3D virtual environment of the eye. This work, cited over 160 times, established foundational principles for surgical robotics and simulation. Sagar’s impact extends beyond engineering into the realm of affective computing and digital health. His later research explores how artificial agents—from embodied conversational agents to chatbots—can reduce patient loneliness and improve mental health, with one study on reducing loneliness garnering 50 citations. Most recently, he has investigated whether virtual humans can enhance mindfulness and reduce stress, a randomized trial that points to new digital interventions for student well-being. Sagar’s unique ability to integrate neuropsychiatry, robotics, and virtual environments has made him a leading figure in creating lifelike, socially intelligent systems that address real-world health challenges.
