He served as President of the Society for Free Radical Research International (SFRRI), founder and Honorary President of the Oxygen Club of California. He has edited numerous books and published research; some of the most cited articles have become classics in the field of free radical biology: Dr Packer is a member of many professional societies and editorial boards. His research elucidated - the Antioxidant Network concept. Exogenous lipoic acid was discovered to be one of the most potent natural antioxidants and placed as the ultimate reductant or in the pecking order of the "Antioxidant Network" regenerating vitamins C and E and stimulating glutathione synthesis, thereby improving the overall cellular antioxidant defense. The Antioxidant Network is a concept addressing the cell's redox status. He established a world-wide network of research programs by supporting and co-organizing conferences on free radical research and redox biology in Asia, Europe, and America.
