Researches, develops, and applies science principles in environmental issues, Big History evolutionary trends, and particle scattering. He has a BS in Physics from CalTech, a PhD in Computer Science from DePaul, and over 30 years of experience at Argonne National Laboratory in the development of scientific analyses, software, training, and modeling. His research interests include Big History synergistic trends among energy, environment, organization, and information. He has presented at the IBHA conferences since the first in 2012 and has presented an IBHA webinar in Oct 2021. He has published articles in the Journal of Big History, the Evolution Almanac, and in 2020 co-edited a book with Andrey Korotayev concerning a Big History perspective of the singularity trend. He (along with Ken Solis) contributes to the “From the Journal” column of the newsletter and now also collaborates on the Emergence newsletter publication.  He has started a Big History Research Group for continued international virtual conferencing and online communication.

Ken Solis, MD, MA | Treasurer

Ken Solis is a retired internist and ER physician with a master’s degree in bioethics. His long trips to and from work over the years also gave him many hours to listen to lectures on other fields in the sciences, philosophy, and history. By coincidence, he was teaching “A Brief History of the Universe” to adults before he encountered David Christian’s big bistory lectures for “The Great Courses.” His special interest in big history is what thermodynamics, information theory, and complexity science might reveal about how systems have, depending on the circumstance, progressed, regressed, and diversified over time. He has also applied these disciplines to the formulation of an information-centric ethical theory that was published in JBH.

Board Members

Lowell Gustafson

Lowell Gustafson is currently a member of the IBHA Board, IBHA Treasurer, Associate Editor of the Journal of Big History, and editor of Origins: The Bulletin of the IBHA. He earned his PhD in Government and Foreign Affairs from the University of Virginia in 1984 and has been on the Political Science faculty of Villanova University since 1986.

He finds the development of an evidence based narrative of a 13.8 billion year series of developments from the big bang to present, along with reasoned expectations about the future, to be one of the great achievements of humanity. He highly values associating with others who share a fascination with integrating fields of knowledge and the meanings that a universe of knowledge offers humanity.

Heathe Kyle Yeakley | IT Director

Heathe Kyle Yeakley was born and raised in Oklahoma, where he discovered paleontology on an elementary school field trip in the early 1980’s. It fascinated him to think that Earth had existed for so long that entire ecosystems populated with strange and wonderous creatures had come into being, existed for millions of years, collapsed, and, with their demise, laid the foundation for the cycle to repeat.

In college, he pursued technology as a profession but kept paleontology as a primary hobby. In 2000, he began to volunteer and the then-brand-new Sam Noble Oklahoma Museum of Natural History. Over three years, he accrued hundreds of hours of volunteer work interpreting ancient life exhibits for the public while working full-time and working towards a technology degree.

Today Heathe holds degrees in telecommunications and network management. He is a senior Linux DevOps Engineer and provides technology services to financial companies operating on the American East Coast.

When not looking for ways to apply his technology skills to explore deep time, he can be found watching courses by the Teaching Company and playing with his dogs.

Barry Rodrigue

Barry Rodrigue (Ph.D. Université Laval 1999) is a geographer, archaeologist and folklorist, serving as Full Professor of Anthropology and Scholar-in-Residence at Symbiosis International University, Pune, Maharashtra (India). He began his career as an ethnographer and field biologist in Alaska, where he studied natural / cultural landscapes among Indigenous communities. A Fulbright Scholar, he worked as a research geographer at Université Laval (Québec) and associate professor of humanities at the University of Southern Maine (USA). His strategy of integrating local, regional and global inquiry into a unified context made him an early advocate of universal studies. This was not surprising, since he was a student of astrophysicist G. Siegfried Kutter, a developer of Cosmic Evolution and Big History. A founder of the International Big History Association (2010) and the Asian Big History Association (2014), Barry also served as their international coordinator. He was editor-in-chief of the three-volume collection, From Big Bang to Galactic Civilizations: A Big History Anthology, for which he assembled articles by 100 scholars from 25 nations with big-historians Andrey Korotayev and Leonid Grinin. Barry’s present work focuses on global human adaptation, and he is assembling a deep-time study of Southeast Asia’s agriculture and the climate crisis with Earth-scientists Shamshuddin bin Jusop and Firdaus bin Anuar. Barry is a strong proponent of engaged scholarship, where researchers work with grassroot communities around the world to resolve problems through shared ideas and networks.
