The OpenFF team went through some changes in the first half of 2021 – we are excited to welcome six new members to our team and to see some of our old teammates move on to exciting new roles.

We are very pleased to welcome the following new members:

• Josh Mitchell joined in February to help us improve our documentation and tutorials;
• Lily Wang joined in March as a Fulbright Fellow in the Mobley group and works on polymer force field infrastructure;
• Lorenzo D’Amore joined in March as a dedicated OpenFF postdoc with Janssen to continue David Hahn’s work on protein-ligand benchmarking;
• Iván Pulido-Sanchez joined in April as a software scientist to assist with biopolymer infrastructure for 3 months;
• Andrew Dalke joined in May as an independent consultant to assist with cheminformatics topics.
• Chapin Cavender joined in June as a postodoctoral fellow in the Gilson lab to work on biopolymer force fields.

We are also incredibly grateful to:

• Jaime Rodríguez-Guerra, who joined Quansight in May 2021, after his epic efforts to transfer the OpenFF toolkit to conda-forge;
• David Hahn, who started his permanent position with Janssen in January 2021 after workin on protein-ligand benchmarking of (open) force fields;
• Josh Fass, who graduated in the Chodera lab and moved to Relay Therapeutics in November 2020, and who contributed some interesting concepts for automated atom typing and more;
• Josh Horton, who started a postdoc position in the Cole group in November 2020, but who still actively collaborates with OpenFF on bespoke force field parameterization tools.

Thank you all for being such wonderful teammates and valuable members of the OpenFF community, best of luck in your new roles and we are looking forward to your future successes!
