Dr. Lawrence's research centers on the theory and application of control systems. His work is driven by the needs of applications, including autonomous micro aerial vehicles, visual/haptic computer interfaces, spacecraft attitude control, and dexterous teleoperation for micro surgery. This work is highly interdisciplinary, requiring integrated development of mechanical, electronic, real-time computing, modeling, and human interface technologies, together with dynamics and control theory.
