Over the past few weeks, I was in the US. From July 15-17, I participated in the CHARMM meeting, which is organized by Martin Karplus. I gave a talk about recent contributions that I have made to the CHARMM biophysics simulation package. I also visited colleagues in the chemical dynamics section at Argonne National Labs and in Fleming Crim’s group at UW-Madison. During both of these visits, I gave talks about solution phase chemical dynamics.
