Current/Recent Teaching

Artificial Intelligence (CS 440): Fall 2021 and Fall 2020 .

Discrete Structures (CS 173) Spring 2021 and Spring 2020 .

Course Development and Materials

I focus on building materials that are easy for students to learn from. Specifically

As our class size as grown, and particularly since the pandemic lockdown, I have become increasingly interested in techniques for making instruction scale well while preserving the most valuable aspects of in-person time and human feedback

Discrete Structures (CS 173):

I've also been working on techniques for authoring and maintaining large sets of exam questions.

Artificial Intelligence (CS 440)

Fleck and Har-Peled lecture notes for Intro to Theory of Computation (CS 273) which I taught from Spring 2006 to Spring 2008.

Back in the 90's, I developed a laboratory-based computer vision course.


My recent research centers around understanding conversational speech, particularly unsupervised algorithms that learn word boundaries from transcribed speech. I am also interested in use of prosodic features (e.g. stress, duration) in language modelling and language acquisition.

I worked in image understanding for many years and retain an interest in that area. I also have a long-term interest in building better programming language support for AI and have implemented a hybrid LISP/C package for computer vision applications and a hybrid Scheme/C package for linguistic research. At HP labs and U. Illinois, I have worked on systems that provide guidebooks and collect annotated records of personal experiences.


Some useful resources:

Here are the full versions of two software releases. The world has changed too much for the code to run, but they are still useful documentation of the designs.

This is the regularly occurring prta of my schedule. Obviously, I also have one-of meetings and details may change, especially early in each term. Colored items happen every week or every two weeks; uncolored items happen only some weeks.

Due to covid restrictions, I'm rarely in my office. So dropping by won't work as well as it normally does. Please drop me email if you'd like to meet.
