The psychologist Susan Gelman is his older sister.^{[8]} The cartoonist Woody Gelman was his uncle.^{[9]}

Gelman is currently a professor of political science and statistics at Columbia University, where he also directs the Applied Statistics Center.^{[10]} The Applied Statistics Center conducts research with several other departments at Columbia University, as well as containing a number of individual projects.^{[11]} Gelman is a practitioner of Bayesian statistics,^{[12]} and hierarchical models.^{[13]}

He is a major contributor to the statistical programming framework Stan.

Gelman is notable for his efforts to make political science and statistics more accessible to journalists and to the public. He is one of the primary authors of The Monkey Cage,^{[14]} a *Washington Post* blog dedicated to providing informed commentary on politics and making political science more accessible.^{[15]}

Gelman also keeps his own blog which deals with statistical practices in social science.^{[16]} He frequently writes about Bayesian statistics, displaying data, and interesting trends in social science.^{[17]}^{[18]}^{[19]} According to the *New York Times*, on the blog "he posts his thoughts on best statistical practices in the sciences, with a frequent emphasis on what he sees as the absurd and unscientific... He is respected enough that his posts are well read; he is cutting enough that many of his critiques are enjoyed with a strong sense of schadenfreude."^{[20]}

He has been prominent as a critic of alleged shoddy methodological work in the replication crisis.^{[20]}
