IntroductionDistinguished Professor. Research focuses on next-generation photovoltaic and optoelectronic technologies based on van der Waals (vdW) quantum materials, with particular emphasis on hot-carrier photovoltaics, carrier multiplication, contact engineering, and quantum nano-photonics. Held a Marie Skłodowska-Curie Postdoctoral Fellowship at the University of Cambridge in the Department of Materials Science & Metallurgy and the Cambridge Graphene Centre, working on advanced 2D semiconductor devices and quantum optoelectronics. Research contributions include the development of ultrahigh-performance 2D semiconductor devices and emerging concepts such as hot-carrier solar cells and carrier multiplication in low-dimensional quantum materials, with publications in leading international journals including Nature Reviews Physics, Science Advances, ACS Nano, 2D Materials, and Journal of Materials Chemistry A.
