John Edwin Luecke is an American mathematician who works in topology and knot theory.
He got his Ph.D. in 1985 from the University of Texas at Austin and is now a professor in the department of mathematics at that institution.
In a 1987 paper[1] Luecke, Marc Culler, Cameron Gordon, and Peter Shalen proved the cyclic surgery theorem.
In a 1989 paper[2] Luecke and Cameron Gordon proved that knots are determined by their complements, a result now known as the Gordon–Luecke theorem.
Dr Luecke received a NSF Presidential Young Investigator Award[3][4] in 1992 and Sloan Foundation fellow[5] in 1994.
