Shunbo Lei, a postdoctoral fellow who works with Ian Hiskens, Vennema Professor of Engineering, and Prof. Johanna Mathieu, received a Best Reviewer Award from the IEEE Transactions on Smart Grid.

Lei researches the impact of demand response on the energy efficiency of commercial buildings, including buildings here at U-M. Using both experimental and modelling approaches, he investigates the effects of short-term load shifting of heating, ventilation, and air conditioning systems in buildings. He also helps develop optimization algorithms to enhance the disaster recovery logistics of power grids. He’s refined methods for new grid restoration strategies, such as routing and scheduling mobile power sources to provide spatial flexibility for the grid, which enhances grid resilience.

Lei earned his B.E. degree in electrical engineering from Huazhong University of Science and Technology, Wuhan, China, in 2013. He then received his Ph.D. degree in electrical and electronic engineering in 2017, from the University of Hong Kong, Hong Kong, where he was also a Postdoctoral Fellow after graduation. He was a Visiting Scholar at Argonne National Laboratory, Lemont, IL, from 2015 to 2016.

The electrons absorb laser light and set up “momentum combs” (the hills) spanning the energy valleys within the material (the red line). When the electrons have an energy allowed by the quantum mechanical structure of the material—and also touch the edge of the valley—they emit light. This is why some teeth of the combs are bright and some are dark. By measuring the emitted light and precisely locating its source, the research mapped out the energy valleys in a 2D crystal of tungsten diselenide.

Mapping quantum structures with light to unlock their capabilities

Rather than installing new “2D” semiconductors in devices to see what they can do, this new method puts them through their paces with lasers and light detectors. | Medium Read
