The National Science Foundation featured my work
on crowd modeling in a
Research Highlights: "Crowd
control based on individuals". This is the fourth time that
the project has made into their highlights (also "Exploring
crowd behavior in large cities"; "Subtle
movements in crowds lead to large-scale phenomena"; and "Beginning
scientists receive presidential awards") (June 7, 2012)

A couple of new papers on my movement modeling
work and related computing architectures have been published

The Reuters
news agency filmed an interview with me about my riot
and crowd
modeling work. Some of the new work that I have been doing on 4D physics
integraion with the agent-based modeling pipeline also
featured in the segment. This has now been picked up by a variety of
newspapers, news shows, and magazines, including
CBS,
ABC,
the Baltimore Sun,
the Chicago Tribune, and
Scientific American. (January 2, 2012)

My research on riot modeling is featured in Bill
Wasik's cover story for the January edition of Wired magazine in
the United States: "#Riot:
self-organized, hyper-networked revolts—coming to a city near you".
Wired
(see page 82). (December 18, 2011)

New
Scientist has a feature on my riot and crowd modeling work;
currently it is on the front page of their Website: "Virtual
rioters predict how crowds move". More details on the work
are available
here, and I have a paper on the model and application,
co-authored with Aaron McDaniel, forthcoming in the Annals of the Association of
American Geographers in 2012. (November 16, 2011)

I will be giving a talk at George Mason University
in Fairfax, VA on Monday, October 24 at 12. The address is Department
of Computational Social Science, Kransnow Institute for Advanced Study,
Research I, CSC Suite, Level 3, 4400 University Drive, Fairfax, VA
22030. The talk will be on the topic of: "Animating agent movement in
computer models: fusing theory, technology, big data, and
machine-learning". (October 21, 2011)

New paper accepted: Zou, Y.; Torrens,
P.M.; Ghanem, R.; Kevrekidis, I. (2012) “Accelerating agent-based
computation of complex urban systems”. International Journal
of Geographic Information Science. This paper was the
product of my collaboration with Roger
Ghanem at the University of Southern California's Departments
of Civil Engineering and Aerospace and Mechanical Engineering, and Ioannis
Kevrekidis and Yu
Zou at Princeton University's Department of Chemical and
Biological Engineering. We have been developing a meta-simulation
infrastructure for accelerating agent-based modeling, using Ioannis's
equation-free approach, Roger's methods for measuring uncertainty, and
my agent-based models. This project is sponsored by the National
Science Foundation's EAGER program; more details of the research are
available here
