ACGIH 2023 Election Results

ACGIH is pleased to announce the results of our recent Board of Directors and Nominating Committee election. Congratulations to all the 2023 election winners!

Jack Caravanos, DrPH, CIH will remain Chair for 2024, and COL(Ret.) Mary S. Lopez, PhD, CPE will become Treasurer.

Three Active Members were elected to serve on the Board of Directors for a 3-year term:

Representing Academia/Government:

Torey Nalbone, Ph.D., CIH, FAIHA. “When asked to consider service on the ACGIH Board again as a Director, I was certainly humbled.  My first tenure on the ACGIH Board was as Vice Chair Elect eventually becoming the Board Chair.  I served a second year as Chair when the governance now called for the Board to select it Chair among the board members. This was certainly a transitional period for in both its governance and its operations.  Five years later I again ran for the Board Director position and was selected to participate in a Board moving forward with those changes and learning different mechanisms to provide for the membership many were started but certainly not finished.  If elected to rejoin the Board, I would be grateful and appreciative of the opportunity to serve the membership for another term to assist in the completion of the transformation of a professional organization started over 10 years ago. As a member of the Board I am committed to protecting the principle that ACGIH service to the occupational and environmental health profession is a professional trust and in some cases clearly an agent for our members success and to make the resources of the organization available to All in the OEHS profession.”

“If elected, I bring previous non-profit board experiences in intellectual property rights management, fund raising and product delivery along with reliance in a diverse professional career to focus on four specific goals over the next three years.  The focus is to capitalize on the Association’s ACGIH plus years of organizational history, reputation, and context worldwide of getting the science in the hands of practitioners worldwide. The first goal, to continue pushing forward to define and develop a climate and culture for ACGIH to prosper as a 501(c)(3) charitable scientific organization (non-profit). Second, continue to work with leaders in the profession to develop and disseminate new knowledge and practices that support greater global participation.  A third is to promote a compelling business model for ACGIH, one that enhances the members’ experience, and embraces appreciation for the hardworking ACGIH staff as part of our overall change efforts. Finally, explore NEW and innovative opportunities to embolden the public visibility of products and services that result.  In summary, that ACGIH clearly offers an inter-connected continuum of products for exposure perception, planning and prevention which are backed by nine decades of a steadfast commitment to excellence and integrity.”

Dr. Nalbone is Associate Dean of the College of Engineering for Academics and Student Engagement at the University of Texas at Tyler.  The College offers seven different engineering degrees and currently has over 35 faculty and nearly 1000 students in undergraduate and graduate studies.  His degrees are from Baylor University, University of Texas at Dallas, and Texas A&M University where he earned his Ph.D. in Interdisciplinary Engineering (focus on Health Protection Engineering).  He has been a continuous member of ACGIH since 1985 and has practiced industrial hygiene for over 40 years in a variety of settings which field/lab work, regulatory enforcement, regulatory oversight/management, teaching, research, and consulting.

He has served on scientific committees of ACGIH in both member and leadership roles and his volunteer experience includes Director Positions on the Academy of Industrial Hygiene (AIH) Secretary Treasurer, 4 years on the American Board of Industrial Hygiene (ABIH), 2 as Chair and most recently 4 years on the ACGIH board, 2 as Chair.  He has also served on boards in his community for children’s museum and the local symphony.  For the last 15 years he has been most involved in the continuous improvement to industrial hygiene education through ANSAC-ABET. He is a member of the Executive Committee for the Applied and Natural Sciences Accreditation Commission (ABET – ANSAC).  Serving as Commission chair from 2018 to 2019.

His continued professional service includes AIHA committees, such as Engineering, Noise Control and several technical committees of ASTM.  Dr. Nalbone is an AIHA Fellow and 2017 recipient of the ACGIH Meritorious Achievement Award.

Pam Susi, MSPH, CIH. Pamela Susi has over 30 years of experience as an industrial hygienist.   She most recently worked for Pennsylvania OSHA Consultation at Indiana University of Pennsylvania (IUP). Prior to that she served as the Exposure Assessment Program Director for CPWR – the Center for Construction Research and Training for 23 years.  Ms. Susi is Board-certified with a Master of Science in Public Health from the University of North Carolina at Chapel Hill.  Prior to entering the field of industrial hygiene, Ms. Susi worked as a journeyman carpenter following a four-year apprenticeship.  It was during those years that she saw firsthand the dangers of work.   Construction not only presented serious safety hazards, but also health hazards including those found on industrial rehabilitation and maintenance projects such as the smelter and chemical plant she worked on.  Health hazards were even more of a concern, in some respects, since the exposure risk was unknown.

While at CPWR she co-chaired, with NIOSH, an Engineering and Work Practice Controls Work Group for construction for twenty-two years.  She conducted research on exposure and control of silica and hexavalent chromium in construction and participated in the preparation of comments submitted to OSHA on behalf of North America’s Building Trades Unions (NABTU) during OSHA rulemaking for the Silica and Hexavalent Chromium Standards. She has co-authored over 20 peer-reviewed publications.  She has also served as a consultant for the New Jersey Work Environment Council providing support to the New Jersey Education Association.  Ms. Susi was elected to serve on the ACGIH Board of Directors in 2020. She views the work of ACGIH as foundational to our profession; it provides the tools necessary to evaluate and control hazards in the workplace, which are always evolving.

Leading Experts Appointed Associate Editors for JOEH

AIHA and ACGIH Appoint Journal of Occupational and Environmental Hygiene Associate Editors

FALLS CHURCH, Va. (July 31, 2023)—AIHA and the American Conference of Governmental Industrial Hygienists (ACGIH) have appointed Igor Burstyn, PhD, and Qingsheng Wang, PhD, PE, CSP, as the new associate editors of the Journal of Occupational and Environmental Hygiene. Also known as JOEH, AIHA and ACGIH have jointly published the peer-reviewed journal on the knowledge and practice of occupational and environmental health and safety since 2004. The two associate editors will assist JOEH Editor-in-Chief, Mike Larrañaga, PhD, CIH, CSP, in selecting articles prior to peer review and guiding authors on manuscript development.

Burstyn is an associate professor at Drexel University and adjunct professor at Utrecht University. His research focuses on identifying the sources and health impacts of occupational and environmental exposures and has led several studies as the primary investigator. In particular, his interests concern the health effects of occupational and environmental exposures on children and pregnant people. He has published extensively on the topics of occupational hygiene, exposure assessment, and occupational and environmental epidemiology and presented his research at numerous conferences. Burstyn has received a doctorate in environmental and occupational health from Utrecht University, as well as a master’s degree in occupational hygiene and a bachelor’s degree in microbiology from the University of British Columbia.

Wang, an associate professor of Chemical Engineering at Texas A&M University, has extensive experience in occupational safety, process and reactive chemical safety, nanocomposite manufacturing, and computational fluid dynamics. An internationally recognized and widely cited researcher with over 165 peer-reviewed journal publications, Wang has been invited to review for numerous journals, serves on five editorial boards, and has received a Certificate of Excellence in Reviewing from the Journal of Loss Prevention in the Process Industries. Wang is also the subject editor for Process Safety and Environmental Protection and associate editor for the Journal of Thermal Analysis and Calorimetry.
