Aug 2019 Open Force Field Consortium Workshop

Posted on 30 Jun 2019 by Karmen Condic-Jurkic


We are hosting the Second Open Force Field Consortium Workshop in La Jolla, CA on August 30-31, 2019. The first two days of the workshop will focus on the progress update and future planning of OpenFF efforts in Year 2. The third day (Sep 1) is reserved for OpenFF team discussions, but open to interested Industry Partners. The event will be again hosted at UCSD campus, but please note that the venue has been relocated from Jacobs Medical Center used in January to the Skaggs School of Pharmacy and Pharmaceutical Sciences building.

The meeting will be open to Consortium members and collaborators, and parts of the meeting will be recorded for posting online with accompanying slides. If you are interested to attend, but currently not involved in Open Force Field Initiative, please reach out at to check availability, as we might have a few additional seats. Remote participation will be enabled with Zoom conferencing.

Details at a glance

     Access details: The closest parking lot is right across the street from School of Pharmacy. To access the meeting area, take the     stairs down to the Health Sciences Education Center (the sign will be on your left side as you go down the stairs). Several     photos of the location are provided for easier orientation and a red arrow points to the mentioned staircase in the second      photo. The floor plan of the venue can be found here and the meeting rooms are highlighted in red.
