ACGIH® is pleased to announce new members for its 2020 Board of Directors and its 2020 Nominating Committee.

ACGIH®’s membership elected three (3) members to serve as Directors on the Board of Directors. They are:

Jack Caravanos, DrPH, CIH. Dr. Caravanos is a Clinical Professor of Global and Environmental Health at NYU’s College of Global Public Health. Prior to NYU, he worked at Hunter College of the City University of New York for 40+ years helping to develop a well-established and successful Industrial Hygiene and Environmental Health program. He guided the Hunter program through three ABET IH accreditation cycles and numerous NIOSH ERC renewals. Since 2005, he has assisted the international non-profit, Pure Earth, with its Toxic Site Inventory Program and has travelled to over 20 countries assisting partners in both the private and governmental sectors in sampling and assessing environmental and occupational health threats from hazardous waste sites and operations. Dr. Caravanos has conducted dozens of environmental and industrial hygiene health assessments of e-waste sites, backyard smelters, gold mining sites and tanneries. He has taken thousands of soil and air samples from urban areas, waste sites, and industrial parks throughout South America, Africa and Southeast Asia. He even cut his way through jungles in the Peruvian Amazon looking for workers using mercury to amalgamate gold. But most importantly, and as a result of his training and experience, he is able to bridge the gap between environmental health and industrial hygiene; usually helping communities realize and address the link between workplace hazards and personal health. Dr. Caravanos has published numerous articles covering an array of hazards in a variety of settings. However, he may be best known for his book Quantitative Industrial Hygiene: A Formula Workbook, which has helped many people on their way to certification and is used in all Fundamentals of Industrial Ventilation and Practical Applications of Useful Equations courses. Dr. Caravanos will serve a three-year term.

Michael J. Ellenbecker, ScD, CIH. Dr. Ellenbecker is Professor Emeritus of Environmental and Occupational Hygiene and Co-Director of the Massachusetts Toxics Use Reduction Institute (TURI) at the University of Massachusetts Lowell. From 1981 to 2014, first at the Harvard School of Public Health (HSPH) and then at UMass Lowell, he has taught graduate students and performed research in occupational hygiene. His research focused on aerosol science and the control of airborne contaminants. He has published more than 80 articles in the peer-reviewed literature and is co-author of two textbooks, Ventilation for Control of the Work Environment and Exposure Assessment and Safety Considerations for Working with Engineered Nanoparticles, both published by Wiley. Dr. Ellenbecker was the 2015 recipient of the AIHA Henry F. Smyth, Jr., Award. Dr. Ellenbecker retired from teaching in 2014 but continues as a Director of Toxics Use Reduction Institute (TURI), a position he has held since 2003. As Director, Dr. Ellenbecker leads a staff of 15 professionals performing research and training and providing technical assistance to Massachusetts industries in the reduction of their use of toxic chemicals. TURI is recognized worldwide for its innovative approaches to reducing toxic chemical use. For 10 years, Dr. Ellenbecker led efforts to provide health and safety support to the University’s NSF-funded Center for High-Rate Nanomanufacturing. His research team performed innovative research into methods to assess and control airborne nanoparticle exposures. Dr. Ellenbecker has served on numerous NIOSH review panels and was a member of the NIOSH Study Section for four years. He has been a peer reviewer for all of the major EOHS journals and was an Associate Editor of the Journal of Nanoparticle Research. He was Co-Chair of the 5th International Symposium on Nanotechnology, Environmental and Occupational Health, held in Boston in 2011. Dr. Ellenbecker is finishing his first term as a member of the ACGIH® Board of Directors and is its current Chair. Dr. Ellenbecker will now serve a second three-year term.

Donald D. Elswick, CIH, CSP, CHMM, CET.

Mr. Elswick has held senior roles within numerous local, state, federal, and professional organizations including the Department of Defense Employer Support of Guard and Reserve (ESGR). Mr. Elswick joined ACGIH® in 2017. He is also a member of the American Industrial Hygiene Association (AIHA), and the American Society of Safety Professionals (ASSP). Mr. Elswick has earned several performance awards and spearheaded critical HSE program turnarounds. In addition, he has experience with Department of Homeland Security Chemical Facilities Anti-Terrorism Standards and GHS, REACH, and TSCA regulations. Mr. Elswick retired as a Commander (CDR) in the United Sates Navy. During his 32 years of service as a Medical Service Corps Officer (Surface Warfare), he was the Industrial Hygiene and Hazardous Material Compliance Officer onboard the 1500-person destroyer tender. He also served as the Preventative Medicine/Environmental Health Officer with 4th Civil Affairs Group (CAG), Detachment #2 in Al Asad, Iraq during Operation Iraqi Freedom II. Mr. Elswick is the advisor to the American Society of Safety Professionals (ASSP) University of Findlay student section. Mr. Elswick will serve a three-year term.

The 2020 ACGIH® Nominating Committee includes three elected members who will serve a one-year term. They are:

James Couch, PhD, CIH, CSP, REHS/RS. Dr. Couch is an Industrial Hygienist in the Division of Science Integration, Science Applications Branch at the National Institute for Occupational Safety and Health (NIOSH). Since joining NIOSH in 2002, he has conducted diverse, impactful scientific studies including criteria document development, retrospective exposure assessments in epidemiological studies, and field-based NIOSH health hazard evaluations in emerging industries and hazards such as cannabis, hazardous drugs, and nanotechnology.

Christine Uebel-Niemeier, PhD Candidate. Ms. Uebel-Niemeier is studying in the Environmental and Industrial Hygiene program at the University of Cincinnati (UC). Her research focuses on health-related biological aerosols, including exposure to aerosolized bacteria and fungi, and traffic-related air pollution. She has presented her research at local, national, and international conferences. She has assisted in teaching both the lecture and field components of the Introduction to Industrial Hygiene graduate course at UC.

David M. Zalk, PhD, CIH. Dr. Zalk has been an ACGIH® member for over 20 years and has been an Industrial Hygienist for over 25 years.
