Y. C. Fung works on solid mechanics, and has contributed to expand its frontiers bordering aerodynamics and biology. He helped to establish the fields of aeroelasticity and biomechanics. He received his BS and MS from the National Central University in China and PhD from the California Institute of Technology. He is the recipient of the National Medal of Science from the President of USA, the Founders Award of the National Academy of Engineering of USA, the von Karman Medal from ASCE. Timoshenko Medal from ASME. Poiseuille Medal from ISB. Borelli Medal from ASB. Landis Award from Microcirculatory Society, and Alza Award from BMES. He is a member of the US National Academy of Science. National Academy of Engineering. Institute of Medicine of NAS. Academia Sinica, and Chinese Academy of Science. He is Honorary Professor of 16 universities in China, and Distinguished Alumnus of Caltech Pin Tong is a preeminent developer of computational solid mechanics. He uses more and more general variational principles that admit less and less restrictive hypotheses. He received his BS degree from Taiwan University, and his MS and PhD from the California Institute of Technology. He was Research Fellow at Caltech. Assistant and Associate Professor of Aeronautics and Astronautics at MIT. Chief of Structures and Dynamics Division of US Department of Transportation. Transportation Systems Center. He is Professor of Mechanical Engineering and Founding Head of the Department at the Hong Kong University of Science and Technology. Author of over 100 papers and a book on Finite Element Method. Dr Tong is regional editor of the Int J of Fracture, and Int J Comp Mech, and President of Far East Oceanic Fracture Soc, HK Soc Theoretical and Applied Mechanics, and HK Sec ASME. Dr Tong received the von Karman Award for his outstanding contribution to structural materials, the Engineer of the Year Award, and the Award for Meritorious Achievement from the US Department of TransportationFung, Y.
