Ann Bui

Theoretical and computational molecular science: optical tweezers, Brownian dynamics and nonequilibrium systems

​Ann Bui is a postdoctoral research fellow in theoretical and computational molecular science at the Australian Institute for Bioengineering and Nanotechnology with the Bernhardt group.  She focuses on the computational modelling and simulations of nonequilibrium optical tweezers systems to determine the nature of binding energies between cells and substrate. 

​Ann has carried out her studies at the University of Queensland. Prior to her appointment at AIBN, she was researching forces, and the calibration of forces, in optical tweezers.
