Epistemix makes software that simulates how emergent phenomena like diseases and ideas spread through populations. Modelers use our platform to forecast the social, economic, health, and political consequences of key interventions, enabling leaders to make decisions based on scientific best-practice.
Don Burke was a physician leading HIV/AIDS vaccine development at the Walter Reed Army Institute of Research, and John Grefenstette was a senior computer scientist at the Navy Center for Applied Research in Artificial Intelligence working on evolutionary machine learning methods.
Shortly after they met in 1997, Don and John joined forces to build computer simulations that yielded insight into how the HIV/AIDS virus uses evolutionary strategies to adapt and spread. Don went on to launch the first program in modeling of infectious diseases at the Johns Hopkins Bloomberg School of Public Health, and John became the founding Chair of Bioinformatics at George Mason University.
When the Pitt Graduate School of Public Health recruited Don to become its dean, he created a new Public Health Dynamics Laboratory—which quickly became a national center of excellence for MIDAS—and invited John to join as founding director. Together, they developed the FRED epidemiological modeling platform and used it to publish over a dozen scientific papers in leading journals.
In 2017, Don and John teamed up with John Cordier to build a business based on their innovations, and Epistemix was born.
Meet Our Team
Donald S. Burke, MD
After earning his BA in Chemistry at Case Western and his MD and medical residencies at Harvard, Dono spent 23 years at the Walter Reed Army Institute of Research where he developed diagnostic tests and vaccines for hepatitis A, dengue, HIV, and other diseases of global importance. Retiring at the rank of Colonel, he moved to academia to become a professor at the Johns Hopkins Bloomberg School of Public Health where he led research and teaching on vaccines and computational epidemiology.
In 2006, he was recruited to become Dean of the Graduate School of Public Health at the University of Pittsburgh (Pitt) where he was responsible for leading 170 faculty and 650 graduate students, with an annual budget of $100 million per year. As Dean he launched a unique program on computational modeling and simulation of public health dynamics that led to the creation of the FRED platform and founding of Epistemix.
In 2019 Don stepped down as Dean and is now the Jonas Salk Chair in Population Health. He has authored over 300 scientific papers and is a member of the National Academy of Medicine.
John Grefenstette, PhD
Chief Technology Officer
John is a computer scientist who has devoted his career to problems at the interface of biology and computation. He has extensive experience in leading highly productive computational science teams, including serving as Head of the Machine Learning Section at the U.S. Naval Research Laboratory, as Chair of Bioinformatics and Computational Biology at George Mason University, and as Director of the Public Health Dynamics Laboratory (PHDL) in the Graduate School of Public Health at Pitt.
He has published over 100 research articles on topics including genetic algorithms, machine learning, intelligent robotics, bioinformatics, databases, high-performance computing, visualization, and simulation models of population health in top-tier journals like Science, the New England Journal of Medicine, Machine Learning, and the Journal of Artificial Intelligence Research, and his work has been featured publications like the Wall Street Journal, the New York Times, Scientific American, and IEEE Expert.
In 2010, John was honored with the Evolutionary Computation Pioneer Award from the IEEE Computational Intelligence Society. He continues to contribute to Pitt as a professor of health policy and management and a senior scientist at PHDL.
Chief Executive Officer
John is a graduate of the Pitt School of Public Health and Joseph M. Katz Graduate School of Business where he received his MBA and MHA degrees. As a graduate student, he joined the team at PHDL to investigate opportunities for commercializing the FRED modeling platform. When customers began demanding the solutions the platform provides, he spun Epistemix out of the university and is now leading its transition from lab to market.
A native of Erie, PA, he received BS and BA degrees from Pitt while on a collegiate athletic scholarship and pursued a career in professional soccer.
John also founded a nonprofit to improve community health through a platform that addresses local health disparities and is an adjunct professor in health policy and management.
