Aihua Xie is a Professor of Physics at Oklahoma State University. Her research interests are focused on biological signaling, protein structural dynamics, and infrared structural biology. Xie has more than 25 years of experience in advanced infrared study on protein structure, dynamics and function, encompassing time-resolved step-scan FTIR, time-resolved rapid-scan FTIR, temperature resolved FTIR, microfluidic rapid mixing FTIR, cryogenic FTIR, high pressure FTIR, synchrotron FTIR, as well as use of picosecond infrared free electron lasers in mid- and far-infrared. Xie is the Director of an NSF funded Advanced Infrared Biology Research Facility which is open to both users from Oklahoma State University as well as external users worldwide.
Xie was elected to Fellow of American Physical Society in 2003. She was the Chair of Division of Biological Physics of American Physical Society (2011). Currently Xie is the Chair of Commission on Biological Physics of International Union of Pure and Applied Physics (IUPAP) (2014-2017).
Xie received her undergraduate education in physics from Zhejiang University (Hangzhou, China), her PhD in Physics & Biophysics from Carnegie-Mellon University (Pittsburgh, USA) supervised by John F Nagle and Walther Stoeckenius (UCSF). After postdoctoral research with Hans Frauenfelder at the University of Illinois at Urbana-Champaign and faculty research at Albert Einstein College of Medicine in New York, she joined the physics faculty of Oklahoma State University in 1997, was promoted to Associated Professor and Professor in 2001 and 2006.
