I am organizing the 2018 University of Arizona Science Lecture Series titled "Humans, Data and Machines" and gave the first talk about "Problem Solving with Algorithms."
I am a co-PI of the UA-TRIPODS (Transdisciplinary Research in Principles of Data Science) NSF Center, one of 12 including MIT, Columbia, and UC Berkeley. Our research groups are studying the theory of large scale networks, data visualization and interpretation, natural language processing, and Bayesian methods for big data.
In 2015-16 I worked at Charles University in Prague as a Distinguished Fulbright Chair. In 2011-12 I worked in Germany as a Humboldt Fellow and in 2006-07 I was in Botswana as a Fulbright Scholar.
We've implemented several algorithms for semantic word clouds; see some examples from the gallery.
The algorithms that generate our maps of Bookland, TVLand, and MusicLand are now available and usable at GMap.
