Lingju Meng

I am a Physicist/Electrical Engineer, focusing on nanophotonics, optoelectronic devices, colloidal quantum dots, MEMS, and nanofabrication. Currently, I am a Professor at Changchun Institute of Optics, Fine Mechanics and Physics (CIOMP), Chinese Academy of Science.

Prior of joining CIOMP, I was a Marie Skłodowska-Curie Postoctoral Fellow at Aalto University, Finland, where I worked with Dr. Sami Franssila and Dr. Vladimir Eltsov, sharpening my MEMS and nanofabrication teeth. Before my European journey, I acquired my Ph.D. degree at the University of Alberta, Canada, under the supervision of Dr. Xihua Wang, focusing on colloidal quantum dot optoelectronics and flexible electronics. I am a recipient of prestigious Chinese Government Award for Outstanding Self-financed Students Abroad for my research works during my Ph.D. career.
