Johnson received his Ph.D. from Cornell University in 1973 under the supervision of David Gries.[5] He took a faculty position in the computer science department at Pennsylvania State University, and later moved to the department of mathematics at Dartmouth.[5] When the Dartmouth computer science department was founded in 1994,[6] he became its first chair.[4]
Johnson invented the d-ary heap data structure,[7][8] and is also known for Johnson's algorithm for the all-pairs shortest path problem.[9][10]
