Hannah Stuart received her BS in Mechanical Engineering from the George Washington University in 2011. She then completed her MS and PhD in Mechanical Engineering at Stanford University in 2013 and 2018 respectively.
Research Description:
Professor Stuart’s research interests include: Dexterous manipulation; Bioinspired design; Soft and multi-material mechanisms; Skin contact conditions; Tactile sensing and haptics.
Mobile robots face a rapidly expanding range of potential applications, including remote exploration, search-and-rescue and household assistance. In many of these cases, the focus of interaction is via the robot’s end-effectors. However, current manipulators have limited capabilities in comparison to their biological counterparts. Our group is interested in improving robot dexterity through building end-effectors with embodied intelligence and robustness, especially for challenging submerged or wet environments. This includes the design of (1) novel grippers and hands, (2) touch perception for autonomous or teleoperated interventions and (3) bioinspired manipulation strategies. This vision includes the advancement of relevant design analysis tools and the validation of concepts by applying technologies in the field.

Professor Dennis K. Lieu was born in San Francisco in 1957. He is a 1974 graduate of Lowell High School. He pursued his higher education at the University of California at Berkeley, where he received his BSME in 1977, MSME in 1978, and D.Eng. in mechanical engineering in 1982. His major field of study was dynamics and control. His graduate work, under the direction of Prof. C.D. Mote, Jr., involved the study skier/ski mechanics and ski binding function.
After graduate studies, Dr. Lieu worked as an advisory engineer in the disk file industry with IBM San Jose, where he directed the specification, design, and development of mechanisms and components in the head-disk-assemblies (HDA) of disk files. He directed the design and control of high performance DC brushless motors and control of spindle and structural vibration in the IBM 3390 disk file. In 1988, Dr. Lieu joined the Mechanical Engineering faculty at UC Berkeley. His interests include applied research in the mechanics of high speed electro-mechanical devices, and the mechanics of magnetically, electro-magnetically, and eddy current generated acoustic noise and vibration. He currently supervises approximately 6 graduate students in the Electro-mechanical Design Laboratory in 2163 Etcheverry Hall. At the University, Prof. Lieu teaches courses in Engineering Graphics and Design of Electro-mechanical Devices. He also leads a special seminar class in the design of protective equipment for sports.

Current Classes Taught
Dr. Kazerooni is a professor of Mechanical Engineering at the University of California, Berkeley, where he also serves as the director of the Berkeley Robotics and Human Engineering Laboratory. With more than 30 years of mechanical engineering experience and a doctorate degree from MIT, he is a leading expert in robotics, control sciences, exoskeletons, human-machine systems and augmentation, bioengineering, mechatronics design, intelligent assist devices, and power and propulsion. Prior to his more well-known research on lower extremity exoskeletons, Dr. Kazerooni led his team at Berkeley to successfully develop robotics systems that enhanced human upper extremity strength. The results of this work led to a new class of intelligent assist devices that are currently used by manual laborers in distribution centers and factories all over the world. These technologies are currently marketed worldwide by leading material handling corporations.
Dr. Kazerooni’s later work focuses on the control of human-machine systems specific to lower human extremities. After developing BLEEX, ExoHiker, and ExoClimber–three super-light, load-carrying exoskeletons–his team at Berkeley created HULC (Human Universal Load Carrier). It is the first energetically-autonomous, orthotic, lower extremity exoskeleton that allows its user to carry 200-pound weights in various terrains for an extended period, without becoming physically overwhelmed. The technology was licensed to Lockheed Martin and now is used for a variety of military applications. Dr. Kazerooni has also developed lower-extremity technology to aid persons who have experienced a stroke, spinal cord injuries, or health conditions that obligate them to use a wheelchair. His medical exoskeleton, Ekso, has successfully allowed those who have been paralyzed to walk, stand, and speak face to face with peers in an upright position.
In addition to his teaching work and research experience in a academia, Dr. Kazerooni is also an entrepreneur. In 2005, he founded Ekso Bionics (www.eksobionics.com), which went on to become a publicly-owned company in 2014 and now supplies medical exoskeleton (Ekso) to a great number of rehabilitation centers worldwide. He is the founder and chairperson of U.S. Bionics, a VC, industry, and government funded company that provides accessible, affordable exoskeletons for the industrial, medical, and military markets (www.usbionics.com).
Dr. Kazerooni has won numerous awards including Discover Magazine’s Technological Innovation Award, the McKnight-Land Grant Professorship, and has been a recipient of the outstanding ASME Investigator Award. His research was recognized as the most innovative technology of the year in New York Times Magazine. He has served in a variety of leadership roles in the mechanical engineering community and is notably the editor of two journals: ASME Journal of Dynamics Systems and Control and IEEE Transaction on Mechatronics. A recognized authority on robotics, Dr. Kazerooni has published more than 200 articles to date, delivered over 130 plenary lectures internationally, and is the inventors of numerous patents.
