1. First Responder Pathogen Detection System (FiRPaDS) Investigator: Bhaskar DasGupta, Computer Science Prime Grant Support: NSF (including a CAREER grant) Problem Statement and Motivation Technical Approach Key Achievements and Future Goals Need to identify unknown virus sequences during events such as epidemic or biological warfare We only have a database of known virus sequences Few complications of the real-world problem: Sequence has mutated (possibly maliciously) Impossibility to obtain entire DNA sequence Sample may be contaminated and/or contains mixture of sequences. Rapid amplification of the collected genetic material, e.g., via degenerate oligonucleotide primer based multiplex PCR A pathogen fingerprinting and/or barcoding component built around universal DNA tag arrays Rapid and robust computational procedures to compute barcodes that produces short signatures of sequences Two possible approaches to design FiRPaDS: Target based FiRPaDS Primer based FiRPaDS Developed efficient barcoding algorithms using combinatorial techniques Software available from http://www.cs.uic.edu/~dasgupta/professional/software.html http://www.cs.uic.edu/~dasgupta/professional/software.html Will extend barcoding approaches for more complicated scenarios such as mixture of samples Will generate an efficient solution for a combinatorial or graph-theoretic formulation for the degenerate multiplexed PCR minimization problem Will investigate applications of universal DNA tag arrays for helpful coordination with barcoding or fingerprinting steps

2. Virtual Reality and Robots in Stroke Recovery Investigators: Robert V. Kenyon, Computer Science; James L. Patton, RIC Prime Grant Support: NIH, NIDRRMission: To evaluate the utility of simple robotic devices for providing rehabilitation therapy after hemispheric stroke. The integration of virtual reality and robot technology increases flexibility in training for patients recovering from stroke. Promoting innovative techniques to train the nervous system for the recovery of functional movement. Technical Approach: Key Achievements and Future Goals: Personal Augmented Reality Immersive System (PARIS): Virtual and physical objects seen by user. Robotic systems: PHANToM, Haptic Master, WAM: These back-drivable robots provide force to the subject only when commanded to do so. Software integration: Real-time interactivity requires rapid communication between the different components of the rehabilitation system and must contain consistent representations of what the user should feel and see. The robot’s control must quickly communicate with the display control so that graphics are synchronized with the robot’s state. This system provides a platform for exploring how the nervous system controls movements, teaches new movements, explores novel strategies for training and rehabilitation, assesses and tracks functional recovery, and tests and challenges existing theories of rehabilitation. Such a system will determine the necessary levels of quality for future design cycles and related technology. Future designs will lead the way to new modes of clinical practice and to the commercialization of such systems.

3. Computational Tools for Population Biology Tanya Berger-Wolf, Computer Science, UIC; Daniel Rubenstein, Ecology and Evolutionary Biology, Princeton; Jared Saia, Computer Science, U New Mexico Supported by NSF Technical Approach Collect explicitly dynamic social data: sensor collars on animals, disease logs, synthetic population simulations, cellphone and email communications Represent a time series of observation snapshots as a layered graph. Questions about persistence and strength of social connections and about criticality of individuals and times can be answered using standard and novel graph connectivity algorithms Validate theoretical predictions derived from the abstract graph representation by simulations on collected data and controlled experiments on real populations Key Achievements and Future Goals A formal computational framework for analysis of dynamic social interactions Valid and tested computational criteria for identifying Individuals critical for spreading processes in a population Times of social and behavioral transition Implicit communities of individuals Preliminary results on Grevy’s zebra and wild donkeys data show that addressing dynamics of the population produces more accurate conclusions Extend and test our framework and computational tools to other problems and other data Problem Statement and Motivation Of the three existing species of zebra, one, the Grevy's zebra, is endangered while another, the plains zebra, is extremely abundant. The two species are similar in almost all but one key characteristic: their social organization. Finding patterns of social interaction within a population has applications from epidemiology and marketing to conservation biology and behavioral ecology. One of the intrinsic characteristics of societies is their continual change. Yet, there are few analysis methods that are explicitly dynamic. Our goal is to develop a novel conceptual and computational framework to accurately describe the social context of an individual at time scales matching changes in individual and group activity.
