Alma mater	Dartmouth College, Princeton University
Known for	Geometric measure theory
Scientific career
Institutions	Oregon State University
Doctoral advisor	Frederick J. Almgren, Jr.

Parks obtained his Ph.D. in 1974 from Princeton University, under the supervision of Frederick J. Almgren, Jr.^[2] In 2012, he became a fellow of the American Mathematical Society.^[3]

He has developed and implemented a computational technique for computing parametric area minimizing surfaces. He derived an existence and regularity theory for a class of constrained variational problems. Parks has discovered, and characterized, a type of minimal surface with surprising properties, defined in terms of the Jacobi elliptic functions.
