Janet Wong is a Senior Lecturer in the Tribology group, Mechanical Engineering Department, Imperial College London. She received her Ph.D. from the University of Illinois at Urbana-Champaign in 2008 with a dissertation on the physics of confined polymers and joined Imperial College right after. Janet is a specialist in interface phenomena, polymer dynamics and nano-tribology and has pioneered the application of fluorescence spectroscopy and imaging to in-situ measurements of velocity profiles, viscosity, additive interaction and phase stabilities of fluids at tribological contacts and under extreme conditions. 

The Wong Research Group focuses on establishing relationships among (1) properties of fluids in bulk, and in confinement; (2) test conditions, and (3) the resultant mechanical responsesThe Group also is interested in interfacial phenomena including corrosions, adsorption and depositions, and film formations. Her Group works closely with numerical analysts towards fundamental understanding and the development of effective and efficient strategies for the industries

Her work is funded by governmental agencies and industry from Europe, Asia and the US.
