In 2018, he was elevated/elected to Member-at-Large of the USNC/TAM by the National Academy of Sciences:http://www.me.berkeley.edu/about/news/me-professor-tarek-zohdi-appointed-member-large-us-national-academy-sciences-and-national. Overall, he has been a plenary speaker at each of the three major conferences in his field: (a) The World Congress for Computational Mechanics (Sao Paulo , 2012), (b) The United States National Congress for Computational Mechanics (Montreal, 2017) and (c) The International Conference on Particle-based Methods (Stuttgart 2013, Hannover, 2017) and given more than 200 other plenary, keynote and contributed lectures at conferences, universities and other research institutions worldwide. In addition to his academic credentials, Tarek I. Zohdi has been active in five main industrial areas:
- Modeling and simulation of high-strength fabric: Zohdi 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. The analysis of Zohdi 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: Zohdi has worked 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 his ground-breaking book: Introduction to computational micromechanics (T. Zohdi and P. Wriggers, Springer-Verlag).
- 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 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 institute encourages cross-collaboration and sharing of information, where possible, and through various forums to further enhance expanding opportunities. Furthermore, the institute 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: Finally, 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. In 2016, he was the Northern California Principal Investigator for the Northern California Clean Energy Smart Manufacturing Innovation Institute (CESMII); see Whitehouse announcement: https://engineering.berkeley.edu/news/2016/06/california-is-new-headquarters-for-smart-manufacturing-institute/
and https://me.berkeley.edu/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, in 2016, 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 announcements:

Professor Komvopoulos has been in the faculty of the Department of Mechanical Engineering at the University of California, Berkeley (UCB) since 1989. Before joining UCB, he was in the faculty of the Department of Mechanical and Industrial Engineering at the University of Illinois at Urbana-Champaign (1986-1989). Professor Komvopoulos is internationally known for pioneering research in surface nanosciences and nanoengineering, with important implications in several emerging technologies including communications, microelectronics, information storage, and biotechnology. He is the founder and director of the Surface Mechanics and Tribology Laboratory (1989), which in 2008 was split into two laboratories, the Surface Sciences and Engineering Laboratory (SSEL) and the Computational Surface Mechanics Laboratory (CSML), to better accommodate his research programs in different interdisciplinary fields. Professor Komvopoulos holds the positions of Professor of Mechanical Engineering at UCB, Principal Investigator at the Center for Information Technology in the Interest of Society (CITRIS), and Faculty Scientist, Materials Sciences Division, Lawrence Berkeley National Laboratory (LBNL).
The research of Professor Komvopoulos is at the interfaces of mechanical and electrical engineering, materials sciences, surface physical chemistry, bioengineering, and biology. His work is characterized by a multidisciplinary nature and the combination of analytical and experimental techniques used to analyze complex surface and interface phenomena. His research is based on the integration of fundamentals from mechanics, materials, surface chemistry, and biology, and spans a broad range of scales, from the mesoscopic down to the atomic and molecular levels.
Early research accomplishments of Professor Komvopoulos include contact deformation at submicron scales, new friction theories of surfaces interacting in the presence of physicochemically adsorbed monolayers, surface plasticity and fracture of contacting bodies, acoustic emission in surface sliding and machining, synthesis and characterization of ultrathin diamondlike and amorphous carbon films, adhesion forces in miniaturized electromechanical systems, and rheological behavior of boundary films.
In the past two decades, Professor Komvopoulos broadened his research activities, branching into the exploration of various surface microprobe techniques for atomic and molecular level surface analysis, synthesis of self-assembled organic monolayers for reducing adhesion between silicon microdevices, invention of plasma-assisted surface treatments for biopolymers (used in total joint replacements, catheters for minimally invasive treatment of diseased arteries, and cell platforms), deposition of ultrathin (a few atomic layers) amorphous carbon films by sputtering and filtered cathodic vacuum arc for ultrahigh-density magnetic recording and heat-assisted magnetic recording, phase transformations and nanomechanical properties of shape-memory alloys (both in thin-film and bulk form) for retina disks and artery stents, a surface-specific spectroscopy technique (infrared-visible sum frequency generation (SFG) 2 vibrational spectroscopy) for in-situ studies of entropically driven molecular rearrangement at various biopolymer surfaces due to in-plane and out-of-plane stretching and aging effects. His most recent work includes plasma-assisted polymer surface functionalization for controlling adhesion and growth of cells, protein secretion due to mechanotransduction in articular cartilage, cell mechanics, patterned media for single-cell growth, and cell infiltration into fibrous scaffolds synthesized by electrospinning, new electrode materials for Lithium-ion batteries, flexible and stretchable bioelectronics, skin mechanics, and transdermal drug delivery by microneedle arrays, mechanics of biological surfaces, and synthesis of scaffolds with special cues for enhanced biofunctionality.
Professor Komvopoulos research is documented in 245 papers published in peer-reviewed archival journals, 70 papers in refereed conference proceedings, 19 papers in symposium proceedings, 65 technical reports, and 10 US patents. He has also authored an undergraduatelevel textbook (Mechanical Testing of Engineering Materials) and co-authored two monographs (Long Term Durability of Structural Materials: Durability 2000 and 1999 Interface Tribology Towards 100 Gbit/in2 ). He has given 217 scholarly presentations at international conferences, academic institutions, national laboratories, and various industries, supervised the research and dissertations of 55 graduate students (31 PhD and 24 MS) and 15 post-doctoral students, visiting faculty, and industry fellows, and consulted for a wide range of industries and law firms on various litigation matters. Professor Komvopoulos is Fellow of ASME, Fellow of STLE, and recipient of several awards, including NSF Presidential Young Investigator Award (1989-1996), IBM Faculty Development Award (1990-1992), Berkeley Engineering Fund Award (1989-1990), ASME B. L. Newkirk Award (1988), and NSF Engineering Initiation Award (1987).

Professor Johnson’s research can be broadly categorized as materials characterization at the intersection of mechanical engineering and materials science. The thrust of his effort is to under-stand macroscopic material behavior in terms of its microstructure and to develop material models that accurately capture the response of a wide range of materials. His recent work falls into four areas: 1) microscopic modeling of failure modes in brittle materials, 2) understanding the failure of materials under impact loading, 3) developing macroscopic material models for the large-deformation response of metals, and 4) application of X-ray tomography with micron-level resolution to visualize the growth of damage in structural materials. Professor Johnson is also currently the Chair of the Board on Admissions and Relations with Schools (BOARS), a committee of the systemwide Academic Senate for the University of California.
