# Charles Robert Hadlock

Charles Robert Hadlock (born April 19, 1947, in Brooklyn, New York City) is an American applied mathematician, professor emeritus of mathematical sciences, and consultant in risk analysis. In 1985 he was awarded the inaugural Beckenbach Book Prize for his 1975 book Field theory and its classical problems. In July 2019 he was a George Póya Lecturer.

## Education and career

In June 1964 Charles R. Hadlock graduated from Brooklyn's Xaverian High School. In 1967 he received from Providence College a bachelor's degree in mathematics. In 1970 he graduated from the University of Illinois Urbana-Champaign with a Ph.D. in mathematics. His Ph.D. thesis Singular Perturbations of a Class of Two Point Boundary Value Problems Arising in Optimal Control was supervised by Petar V. Kokotovic. Hadlock was from 1970 to 1975 an assistant professor of mathematics at Amherst College and from 1976 to 1977 an assistant professor of mathematics at Bowdoin College. At the management consulting company Arthur D. Little, he was from 1977 to 1979 a senior consultant and from 1979 to 1990 a manager in safety and environmental risk. After 13 years in corporate consulting, he became in 1990 a professor in mathematical sciences at Bentley College (renamed in 2008 Bentley University). There he served as department chair and dean of the undergraduate college. He retired as professor emeritus in 2019. For the academic year 1996–1997 he was on leave of absence as a visiting professor of earth, atmospheric, and planetary sciences at Massachusetts Institute of Technology.
Hadlock's research in applied mathematician involves risk analysis, agent-based simulations, environmental management, service-learning, and various forms of mathematical modeling. During his years with Arthur D. Little, Inc., he worked on environmental cases such as the Love Canal toxic chemical pollution, the Bhopal disaster, and the Three Mile Island accident. His research and teaching dealt with mathematical models of stability of societal structures, economic and environmental changes, new forms of conflict, and bad leadership in the corporate and public sectors.

## Personal life

In 1967 Charles R. Hadlock married Joanne Theresa Miscione. They became the parents of a son and daughter. For many years, during every summer there were family gatherings near a lake in Michigan. After raising their two children, Joanne Theresa Hadlock earned a Ph.D. and became a licensed psychologist. She also wrote a book Yard Sale Savvy: The Ultimate Guide to Bargains, Treasures, and Fun, published in 2011. In 2021, Charles and Joanne Hadlock retired to an oceanside community in Scarborough, Maine.
