Lisa Marie Piccirillo (born 1990 or 1991)[1] is an American mathematician who is the Sid W. Richardson Regents Chair in Mathematics at the University of Texas at Austin.[2] She works in the fields of geometry and low-dimensional topology. In 2020, Piccirillo published a mathematical proof in the journal Annals of Mathematics determining that the Conway knot is not a smoothly slice knot,[3][4] answering an unsolved problem in knot theory first proposed over fifty years prior by English mathematician John Horton Conway.[5]
From 2020 to 2024, she was an assistant professor of mathematics at the Massachusetts Institute of Technology.[6]
