He serves on the editorial advisory boards of ten international journals. Also, he is an editor of the leading journal Computational Mechanics and co-founder/co-editor-in-chief of journal, Computational Particle Mechanics, as well as an editor of the Computational Mechanics book series, published by John-Wiley. He has organized or co-organized over 30 international conferences and workshops and been appointed/invited to the Scientific Advisory Boards of over 40 international conferences. He was elected President of the USACM in 2012, and served from 2012 to 2014. Since 2009, he has served as a representative of the USACM on the General Council of the IACM, which is the governing committee of the primary international organization in his field of research and was elected to the Executive Council of IACM in 2020 (seven were elected worldwide in 2020). In 2014, he was appointed by the United States National Academy of Science (NAS) and the National Research Council (NRC) as a member of the US National Committee for Theoretical and Applied Mechanics (USNC/TAM) representing the USACM (4/15/2014-10/31/2018): https://www.nationalacademies.org/our-work/us-national-committee-for-theoretical-and-applied-mechanics-usnc-iutam. USNC/TAM is the primary national governing body for Mechanics in the United States. This committee operates under the auspices of the US Board on International Scientific Organizations (BISO) and the Policy and Global Affairs Division of the NRC. Furthermore, he is the national coordinator for the NAS and USNC/TAM for AmeriMech Symposia, which are intended to promote interactions among researchers in an area of contemporary interest in the mechanics of fluids and solids http://sites.nationalacademies.org/pga/biso/iutam/pga_086043. These symposia are designed to encourage participation of young researchers, and to promote interdisciplinary ideas and discussions. This format allows for in-depth discussions and close interactions between participants. Such symposia are renown to help assess the state-of-the-art and chart new directions for the future. 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:
  https://me.berkeley.edu/news/dod-announces-award-new-advanced-robotics-manufacturing-arm-innovation-hub/
  and https://engineering.berkeley.edu/news/2017/01/berkeley-a-regional-center-in-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.
