Personal profile
About Me
Research:
We develop molecular theories of polymer structure and dynamics in various systems, including: polymer membranes, liquid-liquid phase transitions, elastomers, and bio-polymer networks. We seek to understand the molecular mechanisms responsible for polymer behavior and corroborate them using molecular dynamics simulations.
We explore the role of polymers in advanced materials and in biology using theory and computer simulations.
Our research interests include:
• Chain and network elasticity
• Polymer membranes for separation of small molecules
• Biopolymer networks
• Liquid-liquid phase separation
M.Sc., Ph.D., and postdoc positions are available!
Please contact Liel with a CV and a short cover letter stating your research interests and background.
