The signac project was launched in 2015 by the Glotzer Group at the University of Michigan. More background on the design philosophy and implementational concepts are published in volume 146 of the Journal of Compuational Materials Science:

Carl S. Adorf is the lead developer and maintainer of the core signac and the signac-flow package. His research interests include the optimization of particle interaction models for the self-assembly of materials with complex structures and best practices in scientific computing.

Paul M. Dodd co-founded the project and contributed significantly to the early concepts and implementation of both signac and signac-flow. His research interests include the folding pathways of polyhedra and shape packing problems.

Vyas Ramasubramani joined the project in 2016 and has since provided valuable contributions both in terms of user feedback as well as development of the signac-flow package. His research interests include depletion induced self-assembly of structural matter.

Bradley Dice joined the signac development team in 2017 and has contributed the signac-dashboard package, which enables users to visualize and search data managed with signac within a web browser. Bradley is studying the self-assembly pathways of rounded shapes.

Sharon C. Glotzer is the principal investigator for the signac project and the John W. Cahn Distinguished University Professor at the University of Michigan, Ann Arbor, the Stuart W. Churchill Collegiate Professor of Chemical Engineering, and the Anthony C. Lembke Department Chair of Chemical Engineering. She is also Professor of Materials Science and Engineering, Physics, Applied Physics, and Macromolecular Science and Engineering. Her research focuses on computational nanoscience and simulation of soft matter, self-assembly and materials design, and the development of software to support the research. She is a member of the National Academy of Sciences and the American Academy of Arts and Sciences, and a fellow of the American Physical Society, the AAAS, the AIChE, the Materials Research Society (MRS), and the Royal Society of Chemistry. She is a Simons Investigator, a former National Security Science and Engineering Faculty Fellow, and the recipient of numerous other awards and honors, including the 2017 MRS Lecturer Award, the 2016 Alpha Chi Sigma Award from the AIChE, the 2014 MRS Medal and the 2008 Charles M.A. Stine Award from the AIChE. With 250 publications and more than 330 plenary, keynote, and invited lectures around the world, Professor Glotzer is one of the world’s leading computational scientists.
