In 2019 am co-chairing the The 21st ACM-SIAM Meeting on Algorithm
Engineering and Experiments (ALENEX) and serve on the PC of
the 35th Symposium
on Computational Geometry (SoCG) and the 12th IEEE Pacific Visualization Symposium (PacificVis).
In 2018 I served on the PC of the 23rd IEEE Information
Visualization Symposium (INFOVIS), the 20th IEEE Eurographics
Conference on Visualization (EUROVIS), the 11th IEEE Pacific
Visualization Symposium (PacificVis), and the IEEE Conference on Software Visualization (VISSOFT).
I organized 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.
