**CHENNAI, April 21, 2025** – Renowned theoretical physicist A.P. Balachandran passed away on April 18 in Coimbatore at the age of [age not provided in text]. A Joel Dorman Steele emeritus professor at Syracuse University, Balachandran was internationally recognized for his significant contributions to the field, particularly his work on the Skyrme Model, which describes protons and neutrons as topological solitons.
Balachandran, a graduate of Madras Christian College and the University of Madras, was the first graduate student of Matscience (now the Institute of Mathematical Sciences, Chennai). His postdoctoral work took him to Vienna and Chicago. He joined Syracuse University in 1964, playing a crucial role in establishing it as a leading research center for physicists worldwide. His accolades include the 1991 Wasserstrom Award for Graduate Teaching at Syracuse University and recognition from the American Chapter of the Indian Physics Association in 1992. He was also a fellow of the American Physical Society.
Throughout his career, Balachandran authored seven books and monographs, and contributed to over 200 publications on quantum field theory, group theory, and Hopf algebra. His research focused on quantum chromodynamics and the Standard Model, utilizing topology and differential geometry to understand the interactions of subatomic particles. He remained actively involved in research until his death. He is survived by his wife and son.
