I am a professor of Statistics and Computer Science at Columbia University. I am also a member of the Columbia Data Science Institute. I work in the fields of machine learning and Bayesian statistics.

See my CV and publications.

My research interests include:

• Topic models
• Probabilistic modeling
• Approximate Bayesian inference

Here are three recent talks:

• Probabilistic Topic Models and User Behavior
• Variational Inference: Foundations and Innovations
• The Blessings of Multiple Causes

Most of our publications are attached to open-source software. See our GitHub page.

Follow the Blei lab on Twitter.

Here is a postdoc opening, to work with me and Don Green on the intersection of large-scale field experiments and machine learning.

Machine Learning at Columbia

Columbia has a thriving machine learning community, with many faculty and researchers across departments. The Machine Learning at Columbia mailing list is a good source of information about talks and other events on campus. (To subscribe, send email to machine-learning-columbia+subscribe@googlegroups.com.)

Teaching

In Spring 2023 I am teaching Applied Causality. We are focusing on multi-environment learning.

All my courses are here.

Office hours

During the academic year I hold weekly office hours on zoom. Coming to my office hours is easier than using email to make an appointment.
