Dr. George Chronis

CEO and Chief Technology Officer

Dr. Chronis received his PhD in Robotics and Artificial Intelligence from the University of Missouri. His work and publications are in computational intelligence and include autonomous mobile robot navigation, spatial relations, linguistic spatial cognition, programming by demonstration, fuzzy logic and evolutionary computation.

Prior to Foresite Healthcare Dr. Chronis founded CyberSense, a software solutions and development company undertaking projects with more than 100 educational organizations worldwide and with large corporations such as Monsanto, University of Arizona and University of California. Projects developed and managed span a wide variety of demanding, large scale, data and computation intensive applications such as intelligent prediction and expert system advice on industry trends based on meta-data such as customs’ import/export records, electronic manuscript management and automated peer-review for millions of users, various crop and seed optimization from planting to sales using GPS guided image processing, data mining and neural network computation and data mining algorithms for agrobiotechnology economics based on meta-data processing from the US Patent Office.

Dr. Chronis develops and commercializes technology to improve quality of life by generating early illness alerts. He was instrumental in the development of Foresite Patientcare™, Foresite Eldercare™ and Foresite Health at Home™.

Dr. Erik Stone

Director of Research and Development

Dr. Stone received the B.S. degree in electrical and computer engineering, the M.S. degree in computer engineering, and the Ph.D. degree in electrical and computer engineering from the University of Missouri in 2006, 2009, and 2013, respectively. His research interests span the areas of computer vision, machine learning and pattern recognition.

While earning his Ph.D., Dr. Stone worked as a graduate research assistant, an NSF GK-12 Fellow, and a Teaching Fellow in the Electrical and Computer Engineering Department. After receiving his Ph.D., he worked briefly as a postdoctoral fellow in the Center for Eldercare and Rehabilitation Technology. Dr. Stone’s publications have focused on the development of novel, unobtrusive technologies for measurement of physiological signals outside of laboratory settings, as well as techniques for relating these measurements to traditional instruments used by clinicians. Dr. Stone was instrumental in the development of Foresite Patientcare™, Foresite Eldercare™ and Foresite Health at Home™.

Advisory Board

Dr. Marilyn Rantz

Researcher and Healthcare Advisor


Dr. Rantz is a Professor of Nursing who has been affiliated with the MU Sinclair School of Nursing since 1992. She holds the named position of University Hospital Professor of Nursing, has an appointment as Professor in the Department of Family and Community Medicine in the MU School of Medicine, was designated as a Helen E. Nahm Chair with the School of Nursing in 2008 and was awarded the prestigious University of Missouri Curators’ Professor Title in 2010.

Dr. Rantz’s pioneering work in nursing home care quality spans thirty years, first in practice then as a leading researcher in the Midwest, and establishes her as a premier international expert in quality measurement in nursing homes and research programs to improve quality of care of older people. In late 2012, she secured a $14.8 million grant from the Centers for Medicare and Medicaid Services for their Initiative to Reduce Avoidable Hospitalizations among Nursing Facility Residents; the largest ever received across the entire University of Missouri-Columbia campus.

She has served as principal investigator on grants funded from the National Institutes of Health, the Agency for Healthcare Research and Quality, MO Department of Health and Senior Services, the Administration on Aging, among other associations and foundations. In her role as Associate Director for the MU Interdisciplinary Center on Aging, she also served as principal investigator for “Building Interdisciplinary Geriatric Health Care Research Centers,” which was funded in 2007-2009 through the Hartford Foundation. Dr. Rantz and her interdisciplinary research teams received nearly $60 million to conduct research in long-term care, new delivery models of care for older adults, and most recently, for technology development to enhance aging in place of community-dwelling elders.

At both local and national levels, Dr. Rantz’s professional contributions most recently include election to the Institute of Medicine in 2012. In 2005, she received both the MUSSON Faculty Award for Excellence in Research and the National Gerontological Nursing Association Lifetime Achievement Award. She was awarded the MU Alumni Association Faculty Alumni Award in 2006 for outstanding contributions to her profession, community, and MU; was inducted as a Fellow into the Gerontological Society of America in 2007; and her Aging in Place Project won the American Academy of Nursing Edge Runner Award in 2008. In 2010, she received the Midwest Nursing Research Society’s Distinguished Contribution to Research in the Midwest Award and was awarded the 2011 AAN Nurse Leader in Aging Award. In 2012, she became the only individual to be twice named as an Edge Runner for two different innovations, securing her second for her long-running Quality Improvement Program for MO project. Most recently in April 2013, she received the UM System President’s Award for Economic Development.

Dr. Rantz was instrumental in the development of Foresite Patientcare®, Foresite Eldercare® and Foresite Health at Home®.
