Dr. Cai, who was recently made a postdoctoral By-fellow at Churchill College, combined "nonlinear tomography" with the latest laser gas measuring techniques. This work enables the simultaneous spatial distribution analysis of the multiple parameters including the temperature, pressure, and concentration of several gas components. This work was recently published in Applied Physics Letters [1,2].
Dr. Cai is the youngest recipient this year among all the four awardees. The award represents an international recognition of excellence in the field of analytical science and technology.
