Speaking/Presenting: Contact me if you want to inquire about about having me give a nontechnical public talk or an academic talk on: data science; social justice; teaching and learning; applied topology; collective behavior; patterns in nature; or any other area I work in.

Justice and the Law: Check out JUSTFAIR (the first project to make sentencing decisions of federal district judges available to the public on a broad scale) and our study of incarceration in NYC jails during the early days of COVID, which uncovers both some disturbing details and some opportunities for change.

Teaching Resources: Sometimes people come here looking for an example of my visual syllabi or for resources on antiracist teaching. If you want to discuss either with me, please get in touch.

QSIDE: I co-founded and serve as Executive Director of Research for QSIDE, the Institute for the Quantitative Study of Inclusion, Diversity, and Equity. An independent 501(c)3 nonprofit organization, QSIDE brings the vanguard of quantitative tools to bear on issues of social justice in the arts, crime and criminal justice, health care, higher education, pop culture, and more.
