After receiving a Bachelor of Arts in History from Yale University, summa cum laude, Dan worked for a public defense agency in Brooklyn, NY as an investigator in criminal and immigration cases. He later developed an interest in public history by working as an educator at the Lower East Side Tenement Museum in New York City. He is interested in 20th century American urban history, focusing on the connections between urban space and carceral space, the role of technology and bureaucracy in the development of the carceral state, and historical alternatives to mass incarceration.
Dan works as a Fellow at the Princeton Writing Center and has contributed research to the Princeton and Slavery Project, documenting Princeton's historical ties to the institution of American slavery. He is currently working with Professor Alison Isenberg on a GIS mapping visualization of the urban unrest in Trenton, NJ in 1968.
