Dr. Junjie Niu's Lab Website

Prior to coming to the University of Wisconsin - Milwaukee, Junjie Niu was a Postdoctoral Associate in Departments of Nuclear & Materials Science and Engineering at Massachusetts Institute of Technology. He received his Ph.D. in Materials Science in 2005. He was a faculty member at Shanghai JiaoTong University (SJTU) before joining Prof. Yury Gogotsi's group at Drexel as a Postdoc. From 2011 to 2014, he moved to Prof. Ju Li's group at UPenn and MIT, developing a new lab and leading experimental research. Dr. Niu’s interdisciplinary research includes understanding fundamental science in physics/chemistry, and engineering materials in applications of energy storage, water treatments and chemo-mechanics.

Niu has published more than 80 papers in prestigious journals including Nature sister journals--Nature Nanotechnology and Nature Communications and two book chapters; By 3/2022, his total citation was 11,500+ times with a H-index of 44 and i10 index of 102.
