ABOUT ME

Zhizhang was born and raised in Hunan Province, China. He earned his PhD in Geochemistry from University of Wisconsin-Madison in 2015. After graduation, he moved to Pacific Northwest National Lab for post-doctoral research. He moved back to Madison and joined the Van Lehn group in the Fall of 2018.

RESEARCH INTEREST

My research focuses on understanding the adsorption of polymer-wrapped carbon nanotubes to synthetic surfaces. I am further interested in using coarse-grained simulations to predict the disruption of lipid vesicles by adsorbed proteins.

In previous research, I applied atomistic simulations to gain molecular insights into the (bio)geochemical processes at the mineral-water interface. During my doctoral study, I combined ab initio calculations and classical molecular dynamics (MD) simulations to reveal the effects of catalysts on magnesium dehydration during dolomite growth. In addition, I have applied rare-event sampling techniques to investigate a variety of geochemical phenomena in aqueous environments, such as the effect of electrolyte adsorption on the isoelectric point of minerals, interparticle forces during nanoparticle growth by oriented attachment, elementary steps of mineral dissolution, and the diffusion of radiolytic species in aluminum hydroxides.
