Yaming LiYaming Li
Visiting Scholar
EMS Energy Institute

Yaming Li is a professor at the State Key Laboratory of Fine Chemicals, Dalian University of Technology, China. He is currently a visiting scholar at the EMS Energy Institute. Li’s research focuses on designing and evaluation of transition metal catalyzed cross coupling reactions, C-H activation, and carbon dioxide transformation and utilization. Projects relate to the conversion of carbon dioxide into chemical feedstock using late transition metal catalysts, for example the development of Ni and Cu catalysts for the coupling of Allyl chlorides with carbon dioxide into acrylic acid; mechanistic studies into the catalyzed carboxylation; and Cu catalyzed C-C, C-N, C-O and C-S Ullmann-type Coupling Reactions.

Shimin LiuShimin Liu
Assistant Professor
Energy and Mineral Engineering

Shimin Liu joined Penn State as assistant professor in 2013 after completing his doctoral degree from Southern Illinois University. His expertise is in gas storage and transport mechanism in coalbed methane reservoirs and carbon sequestration in geological formations, especially in the areas of laboratory characterization of gas-coal interaction, analytical modeling of gas transportation under in situ conditions for carbonaceous rocks, volumetric behaviors of coal with gas adsorption/desorption, carbon dioxide sequestration in coal seams, and enhanced gas production. His research interests include: reservoir assessment of unconventional gas resources, reservoir stress changes with depletion, gas drainage from coal mines, and geological carbon sequestration.
