Bingchen Deng

Bingchen Deng is an Assistant Professor in the Department of Intelligent Systems Engineering at Indiana University Bloomington. He received his B.S. degree in Physics from the University of Science and Technology of China (USTC) in 2014 and Ph.D. degree in Electrical Engineering from Yale University in 2020. He worked as a Postdoctoral Fellow at Harvard University from 2020 to 2024 and as a Device Engineer at Intel Corporation from 2024 to 2025.

Dr. Deng’s research explores fundamental sciences in low-dimensional quantum materials and leverages their desirable properties in microelectronic devices and optoelectronic devices. He is interested in quantum confinement effects, light-matter interactions, nontrivial topology, and strongly correlated electrons in a wide range of low-dimensional materials such as two-dimensional graphene, black phosphorus, transition metal dichalcogenides; one-dimensional topological boundaries; and zero-dimensional quantum dots. He fabricates nanodevices and through electrical transport and optical spectroscopy measurements (often at cryogenic temperatures), he uncovers exotic physical phenomena absent in classical materials. He engineers these newly discovered physical properties and seeks practical applications of quantum materials, especially in the semiconductor industry, quantum technologies, and optical sensing. He is also interested in new material synthesis for interrogation of fundamental physics and for enabling new technologies.

Dr. Deng’s research has been published in over 30 peer-reviewed papers in high-profile journals including Nature Photonics, Nature Nanotechnology, Nature Materials, Nature Communications, Science Advances, Physical Review Letters, etc., and has been cited more than 4,000 times.
