Emily Riehl

Emily Riehl is an American mathematician who has contributed to higher category theory and homotopy theory. Much of her work, including her doctoral thesis Algebraic model structures, defended at the University of Chicago in 2011 under J. Peter May, concerns model structures and more recently the foundations of infinity-categories. She studied at Harvard, where she wrote a senior thesis on local class field theory, and completed part III of the Maths Tripos at Cambridge. After a Benjamin Peirce postdoctoral fellowship at Harvard she joined Johns Hopkins University in 2015, became a full professor in 2022 and holds the Kelly Miller professorship of mathematics. She is the author of the textbooks Categorical Homotopy Theory and Category Theory in Context, and with Dominic Verity of Elements of infinity-Category Theory. She has received the 2021 AWM Joan and Joseph Birman Research Prize, a 2022 AMS fellowship and Simons Fellowships, hosts the n-Category Cafe blog, and has played for the United States national Australian rules football team.
