Charles Hagwood received his B.S. degree in mathematics from A&T State University, Greensboro, NC. Afterwards, he attended the University of Michigan, graduating in 1979 with a Ph.D. in mathematics, writing a thesis entitled "Discrete Nonlinear Renewal Theory", under Michael Woodroofe. Between 1979 and 1981, Hagwood was a John Wesley Young Research Instructor in the Mathematics Department at Dartmouth College. During 1981-1987, he was an assistant professor in the Mathematics Department at the University of Virginia. In 1984, he received a Ford Foundation Fellowship and spent one year at Stanford University, in the Statistics Department. He has worked at NIST since 1987, providing consulting in areas that include reliability, uncertainty, and stochastic processes.
