Emily Riehl is an American mathematician who has contributed to higher category theory and homotopy theory. Much of her work, including her PhD thesis,[1] concerns model structures and more recently the foundations of infinity-categories.[2][3] She is the author of two textbooks[4][5] and serves on the editorial boards of three journals.[6]

Riehl grew up in Bloomington-Normal, Illinois.[7] As a high school student at University High School in Normal in 2002, she won third place in the national Intel Science Talent Search for a project in mathematics entitled "On the Properties of Tits Graphs".[8]
Riehl attended Harvard University as an undergraduate; with Benedict Gross as a mentor, she wrote a senior thesis on local class field theory. She also headed the school rugby team and played viola in the Harvard–Radcliffe Orchestra.[9] After Harvard, she completed part III of the Maths Tripos at Cambridge.[4] She defended her doctoral dissertation, Algebraic model structures, at the University of Chicago in 2011, supervised by J. Peter May.[10]
Between 2011 and 2015, Riehl held a position at Harvard University as a Benjamin Peirce Postdoctoral Fellow. Since 2015, she has been employed at Johns Hopkins University, where she became an associate professor in 2019. In addition, she teaches on edX and has hosted videos for Numberphile.[11][12] Along with Benedict Gross and Joe Harris, she developed a Harvard course on edX titled "Fat Chance: Probability from the Ground Up".[13]
In January 2020, Riehl received the JHU President's Frontier Award, a $250,000 award that "supports individuals at Johns Hopkins who are breaking new ground and poised to become leaders in their field". She is the sixth JHU faculty member to receive the award.[14]
Riehl was awarded the 2021 AWM Joan & Joseph Birman Research Prize "for her deep and foundational work in category theory and homotopy theory."[15][16] She is the fourth winner of this prize. She was named a Fellow of the American Mathematical Society, in the 2022 class of fellows, "for contributions to research, exposition, and communication in higher category theory".[17] In 2022 she was awarded a Simons Fellowship.[18]
Riehl is a host of the n-Category Café, a blog on subjects related to category theory in mathematics, physics, and philosophy.[19] She was a board member of the LGBT mathematical association Spectra.[20]
In addition to her mathematical work, Riehl has competed on the United States women's national Australian rules football team at the Australian Football International Cup,[2][21] and was vice captain of the team at the 2017 cup.[22]
While working as a postdoctoral researcher at Harvard, she played electric bass in the band Unstraight.[2][23] She has also written about "unstraightening" in her mathematical research.[24]
Riehl is the author of three books, with a fourth in preparation:
