Meeting Summary: This is the second of two postdoc conferences in 2017 that will bring together the James S McDonnell Foundation (JSMF) postdocs and the Santa Fe Institute (SFI) postdocs. Emphasis for this conference will be on developing the collaborations formed at the January 2017 conference and promoting new collaborations between the participants. We hope to achieve this with a combination of postdoctoral fellow science talks, research jams and discussion sessions. Major outcomes that we are seeking will be to develop a strong network, build collaborative research, establish best practices for complex systems science research and introduce many of the JSMF postdocs to the Santa Fe Institute. We will aim to prepare participants to communicate their high quality, innovative research effectively to the scientific community and become thought leaders who shape the future of science.
