Wonpil ImThe research programs in our group focus on the applications of theoretical/ computational methods to chemical and physical problems in biology and material science.

Specific research interests and projects are

  • peptide/protein interactions with/in biological membranes
  • ion channel activities such as ion permeation, selectivity, and gating
  • NMR structure calculation and refinement 
  • protein translocation through molecular pores
  • membrane fusion with simplified lipid molecules
  • theoretical/methodological developments 

In addition, we are involved in developing the biomolecular simulation program CHARMM, and CHARMM-GUI.
