In addition to his academic credentials, he  has been active in five main industrial areas:

 

  • Modeling and simulation of high-strength fabric: He has  worked extensively in  the computational analysis of high-strength ballistic fabric shielding. Initially, this work was funded by the FAA and Boeing as part of a 10 year (2001-2011) multi-million dollar laboratory and simulation effort to develop ballistic fabric shields for the Boeing 787. He was heavily involved in the  development of 787 Boeing designs. The work was then applied to the development of new ballistic fabric shielding armor (from 2007-present) with the Army Research Labs (ARL) and the Army High Performance Computing Research Center (AHPCRC). In summary, the combined laboratory, modeling and simulation efforts have been instrumental for the development of new types of ballistic fabric shields for the safety and betterment of society.
  • Modeling and simulation of highly heterogeneous materials: He worked extensively in the computational analysis of particulate functionalized materials in multiphysical regimes. This work has been continuously funded by a number of industries, most notably for power-generation materials in harsh environments such as thermal barrier turbine blade coating materials (CMCs: Ceramic Matrix Composites) and high-voltage electromagnetic generator (dielectric) materials, such as End Corona Protection systems. This work has been a direct industrial outgrowth of the  unique book: Introduction to computational micromechanics (T. Zohdi and P. Wriggers, Springer-Verlag: https://cmmrl.berkeley.edu/zohdi-publications/).
  • Modeling and simulation of fire-technologies: In 2018,  he founded the UC Berkeley Fire Research Group(FRG):  https://frg.berkeley.edu/,  whose mission is to serve the best interests of the State of California and society at large, by working toward the development and implementation of more effective solutions for uncontrolled wildfires. The FRG’s mission is to  develop, harness and integrate the state-of-the-art technologies across many fields in order to produce robust and affordable firefighting systems that are easy to maintain, upgrade and deploy for early detection and control of fires. The FRG has brought together engineers, scientists, technologists, first responders and firefighters to bolster research in fire science, management and emergency control.
  • Modeling and simulation of food systems: In 2019,  he  founded the UC Berkeley Center for Next Generation Food Systems: https://food-manufacturing.berkeley.edu/. The overall mission of the center is to optimize societal food production, quality, and food safety/security in the era of pandemics and beyond. These themes are central to California since its economy is the 5th largest economy in the world. The center encourages cross-collaboration and sharing of information, where possible, and through various forums to further enhance expanding opportunities. Furthermore, the center supports the research, education, extension, and economics endeavors designed to advance public knowledge and commercial interests. The center explores themes associated with (a)  pandemic driven food system security and safety, (b) improving food yield, quality, and nutrition, (c) decreasing energy and water resource consumption, (d) increasing production yield and eliminating food waste, (e) large surface-area agriculture, using energy-efficient technologies such as solar and wind and the (f)  use of autonomous systems, drones, sensors and machine-learning for detection of inefficiencies and hazards. The center is part of  a 20,000,000 dollar multi-campus NSF-USDA-NIFA funded network. Zohdi is the PI of the UC Berkeley hub/node. 
  • Modeling and simulation of advanced manufacturing processes: He has  been heavily involved in the National Network of Manufacturing Innovation (NNMI) system that has been developed over the last decade by the US Government. The goal is to add capacity to the National Network of Manufacturing Innovation, a 2014 initiative to increase the competitiveness of U.S. manufacturing by streamlining research and development and increasing collaboration among industry, academia, national labs and federal partners.  Form   2016-2021, he   was the Northern California PI for the Northern California Clean Energy Smart Manufacturing Innovation Institute (CESMII); see Whitehouse announcement: http://engineering.berkeley.edu/2016/06/california-new-headquarters-smart-manufacturing-institute  and http://www.me.berkeley.edu/about/news/president-obama-announces-winner-new-smart-manufacturing-innovation-institute-competition which is part of a 140,000,000 dollar consortium of universities, national labs  and companies geared towards smart clean manufacturing (headquartered at UCLA). The mission of the consortium, consisting of 200 partners from 30 states representing a wide spectrum of interests across industry and academia, is to help hone advanced manufacturing’s competitive edge in the United States by increasing efficiency and accelerating the adoption of technologies such as advanced sensors, data analytics and digital controls in manufacturing. Also, from  2016-2021, he was the California Principal Investigator for another successful consortium NNMI grant (the Advanced Robotics Manufacturing (ARM), headquartered at Carnegie Mellon) in which he  was appointed the coordinator of the Northern California  Branch; see announcement http://www.me.berkeley.edu/about/news/dod-announces-award-new-advanced-robotics-manufacturing-arm-innovation-hub and http://engineering.berkeley.edu/2017/01/berkeley-regional-center-new-robotics-manufacturing-consortium which is part of a 253,000,000 dollar consortium of universities, national labs and companies focused on  advanced robotic manufacturing.

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.
