I have retired from Berkeley, effective end-June 2018. However I will continue with light-duty research and professional activities. In particular I have been updating and expanding my open research problems page. But I am focussing more on my ongoing "Probability and the Real World" activities, below.

July 2018 official launch! Previously haphazard material now organized and expanded.
"Probability and the Real World" project
What aspects of the real world involve chance? What does mathematical probability tell us about those aspects? What concepts from mathematical probability can be illustrated by interesting real data? This web site records my efforts to articulate some answers to such questions. It is aimed at readers who have either read some "popular science" style account of probability, or taken a college course involving probability.

Short cut to Reviews of non-technical books relating to Probability.

Not a Blog: Essays, Musings and Observations

The link goes to an index page, mostly brief articles of mine addressed to students and faculty in probability and statistics and the mathematical sciences. A few recent blog-like observations are below.

(December 2019): Analogous to Wikipedia's nice "zooming in" demonstration of Brownian scaling, Yucheng Wang has made this MP4 demonstration of the emergence of scale-invariance when we grow a network in the plane by adding random points and using a scale-invariant rule for linking them to the existing network. See this 2013 paper amd my discrete spatial networks page for background.

(21 October 2019): The serious contender principle is working pretty well so far for the 2020 Democratic presidential nomination: maximum Predictit prices so far are

(August 2019): A coincidence question. Almost all probability-related questions on Quora are elementary or inane, but I noted a recent one (ironically, soon deleted) that was more interesting to me.

What are the odds that at least 2 players of a 128 players tournament face each other 2 consecutive years?

Here is my brief analysis.

My Research Site
Short cut to Papers and preprints and to slides from recent talks and to open research problems.


For the record, here is a complete list of courses since 2001 (only the most recent version of each course is listed).

For many years I supervised these Undergraduate Research Projects.
