Biography    Tommaso Lenzi received the MS degree in Biomedical Engineering from the University of Pisa in 2008, and the PhD degree in BioRobotics from Scuola Superiore Sant’Anna in 2012. He is currently an Assistant Professor in the Department of Mechanical Engineering at the University of Utah, and a Core Faculty in the Utah Robotics Center. Previously, he was Research Scientist at the Rehabilitation Institute of Chicago (2015-2016), and a Postdoctoral Fellow at Northwestern University (2013-2014). He is a member of IEEE, the Robotics and Automation Society (RAS), and the Engineering in Medicine and Biology Society(EMBS). Dr. Lenzi has co-authored more than 50 peer-reviewed scientific publications, three book chapters, and 9 patents. He serves as Associate Editor for IEEE Robotics and Automation Letters, the International Conferences on Rehabilitation Robotics (ICORR), and Biomedical Robotics and Biomechatronics (BIOROB). His main research interests include robotics, mechatronics, and rehabilitation medicine with a major emphasis on the design and control of wearable robots for human assistance and rehabilitation. Outside academia he enjoys spending time with his wife and two children, playing soccer, riding his Ducati, and playing his Gibson Studio.

Research   My research focuses at the intersection of robotics, design, control, and biomechanics. My primary research interests are related to optimizing the dynamics of human-robot cooperation within the context of physical disability. I aim to discover novel transformative design and control solutions that will allow individuals with a physical disability to recover natural movement ability at home and in the community. Rather than focusing on the impaired biological counterpart and trying to imitate its mechanics with a non-biological device, my research explores non-biomimetic solutions that can build upon the residual, non-impaired abilities of a person, while leveraging on the strengths of artificial technologies such as mechanism, sensors, and feedback control.
