Biography

David A. Dixon (†) Fellow of the European Academy of Sciences (EurASc) Robert Ramsay Chair, Department of Chemistry The University of Alabama, USA Prof. David A. Dixon (1949–2026) was an internationally recognised leader in computational and theoretical chemistry , with seminal contributions spanning fluorine chemistry, catalysis, thermochemistry, heavy-element chemistry, and environmental and energy-related applications. He obtained his B.Sc. in Chemistry from the California Institute of Technology (1971) and his Ph.D. in Physical Chemistry from Harvard University (1976), where his research training included molecular orbital theory and crossed molecular beam chemistry under Nobel Laureates William Lipscomb and Dudley Herschbach. Prof. Dixon’s career combined academic excellence, industrial innovation, and national laboratory leadership. He served on the faculty of the University of Minnesota , spent more than a decade at DuPont Central Research , and later held senior leadership roles at the Pacific Northwest National Laboratory , where he led major initiatives in computational science and the development of widely used electronic structure software. Since 2004, he was based at the University of Alabama , where he led a highly productive research group and was deeply committed to undergraduate and graduate education. His research focused on applying advanced electronic structure methods and large-scale numerical simulations to problems of national and global importance, including energy conversion, hydrogen storage, catalysis, geochemistry, nuclear waste remediation, and environmental chemistry. Prof. Dixon was widely regarded as the world leader in the computational aspects of fluorine chemistry and a pioneer in the industrial application of high-level theoretical methods. Prof. Dixon received numerous prestigious honours, including the ACS Leo Hendrik Baekeland Award , ACS Award for Creative Work in Fluorine Chemistry , multiple federal and university-level awards, and Fellowships of the AAAS , APS , ACS , and European Academy of Sciences. His scientific legacy endures through his publications, software contributions, students, and lasting impact on computational chemistry worldwide.
