New grant from the National Science Foundation's Emerging Frontiers in Research and Innovation (EFRI), via their Resilient Interdependent Infrastructure Processes and Systems program, with colleagues at the University of Southern California and UMD's College of Information Studies: "Human geography motifs to evaluate infrastructure resilience" (August 2, 2014)
New paper, with colleagues Sabya Mishra (University of Memphis) and Tim Welch (Georgia Tech) on our upcoming dashboard technology: Mishra, S.; Welch, T.F.; Torrens, P.M.; Fu, C.; Knaap, E.; Zhu, H. (2014) "A tool for measuring and visualizing connectivity of transit stop, route and transfer center in a multimodal transportation network", Public Transport: Planning and Operations (in press) (August 1, 2014)

A few new papers and chapters on my recent work in modeling acquisition of ambient geographic information and using GI to inform simulated spatial behavior in three-dimensional urban environments are being published (June 9, 2014):

  1. Torrens, P.M. (2014) “High-fidelity behaviors for model people on model streetscapes”, Annals of GIS. In press.
  2. Torrens, P.M. (2014) “Animating peoplescapes in urban models”. In GeoComputational Analysis and Modeling of Regional Systems, S. Dragićević & J.-C. Thill, J.-C. (Eds.) New York: Springer. Forthcoming.
  3. Torrens, P.M. (2014) “Geographical agents in three dimensions”. In Geocomputation: A Practical Primer, Singleton, A. & Brunsdon, C. (Eds.) London: Sage (in press; book is here)
  4. Torrens, P.M. (2014). "High resolution space-time processes for agents at the built–human interface of urban earthquakes", International Journal of Geographical Information Science, 28(5): 964-986
I am directing a new Center for Geospatial Information Science at the University of Maryland, and we are hiring tenure/tenure track faculty and lecturers (December 11, 2013)

New grant from NASA, to develop land cover indicators for the National Climate Assessment (September 12, 2013)

New grant from the National Science Foundation's Division of Advanced Cyberinfrastructure, to support our work on high-performance computing with data and network acceleration, in partnership with the Mid-Atlantic Crossroads (MAX) and their networking infrastructure (September 12, 2013)

Funding of our first NASA grant, to build geographic automata models of ice sheet dynamics. This builds on prototype work to develop physically-realistic environments for automata process models (August 30, 2013)
