LSU Chemistry mourns the passing of Harold Barry Dellinger, Professor Emeritus.  He was born in Charlotte, NC, on September 14th, 1949.  Barry received his BS from the University of North Carolina, Chapel Hill, in 1971 and his PhD from Florida State University with Professor Kasha in 1975.  From 1971-1981, he served his country in the US Air Force and retired at the rank of Captain. He performed postdoctoral studies with the late Professor Robin Hochstrasser at the University of Pennsylvania.  He spent 16 years at the University of Dayton Research Institute. 


Dr Dellinger was recruited to LSU and appointed as Professor of Chemistry and Patrick F. Taylor Chair in 1998.  In the past 18 years, he has published more than 225 papers, brought extensive research funding into LSU, graduated 12 PhD students and advised several postdoctoral researchers and research associates.


He has received numerous awards for his contributions to science, including:

·         ACS Award for Creative Advances in Environmental Science and Technology (2014) for creativity in research and technology or methods of analysis to provide a scientific basis for informed environmental control decision-making processes, or to provide practical technologies that will reduce health risk factors.

·         Elected as Fellow to the Association for the Advancement of Science (AAAS) (2010). This was awarded based on is contributions to science and technology.

·         Astellas USA Foundation Award (2008) for having significantly contributed to scientific research that improved public health through his and his laboratory’s contributions in the chemical and related sciences. 


Dr Dellinger was a member of the founding organizing committee of the International Congress on Combustion By-Products and Their Health Effects and Chair of the Executive Committee until succeeded by Slawo Lomnicki and Stephania Cormier in 2013.   The photos were taken at the 12th Congress in Hanzhou, China.


After a long illness, Barry passed away in the early evening of March 9th, 2016.  Arrangements are being handled by Rabenhorst Funeral Home, Downtown, at 825 Government Street, Baton Rouge, LA 70802.  Visitation will be from 5-7 pm next Wednesday, March 16th with a service to follow at 7 pm.


Thanks to Stephania Cormier, Tina Black, Graça Vicente and Slawo Lomnicki for contributions and to Steph for the photos.



Professor Dellinger addresses the 12th International Congress on Combustion By-Products and Their Health Effects


His research has focused on thermal degradation kinetics and degradation profiles of organic compounds with a special focus on the hazardous organic pollutants. These studies included evaluation of principal organic hazardous pollutants for their destruction and removal efficiency in both pyrolytic and oxidative conditions. His work led to the development of T99 theory or temperature of 99% destruction of chemicals at a specific residence time and formed the foundation for what is used by the EPA to form their incinerability ranking (a guide in the performance tests of incinerator systems). His work has significantly contributed to the understanding of the factors determining the formation of polychlorinated dibenzo-p-dioxins and polychlorinated furans (PCDD/F) in thermal processes. He was the first scientist to propose the integrated model of PCDD/F formation including all 3 pathways of formation (gas phase, surface precursor and de novo). In the last 15 years, his research has increasingly focused on the origin, fate, and health impacts of particle-associated, environmentally persistent free radicals (EPFRs) and combustion generated nanoparticles. His work has always been recognized by industry, policy-makers, the research community and environmental groups.

Research funding has included support from NSF, EPA, tobacco companies, and more recently and substantially, Dr Dellinger was the Director of the LSU Superfund Research Center that received $15,291,598 (2011-16) to investigate the environmental and health impacts of airborne pollutant-particle systems (environmentally persistent free radicals) emitted from thermal remediation technologies or wind-blown dusts created during remediation and containment activities of Superfund wastes.
