Areas of Research

Research Programs and Scholarly Activity

The CIS department is strong in spatial, temporal and graph data mining as well as big data analytics with applications to biomedical databases. The bioinformatics work focuses on understanding disordered proteins and their functions. Additional work in biomedical informatics focuses on developing data management and informatics tools for analyzing large repositories of clinical data and medical images and extracting patterns and associations between anatomical structures and normal or abnormal function. We also apply data mining and machine learning to video analysis and time series analysis. Our work in pattern recognition centers around object recognition, video analysis, shape similarity and perceptual grouping with applications to robot mapping.
 
CIS has a strong research program focused on networked computing, which includes wireless networks and mobile computing, security, resource and system management and parallel and distributed systems. The wireless network and mobile computing areas focus on innovative network architecture, delay tolerant network design, protocol design, and QoS support. The security research studies key management, anonymity design, and secure routing. In the areas of resource and system management, work is centered on applying reputation-based trust models to resource selection and mapping. Parallel and distributed systems work focuses on the principles of lossless high performance systems. Research in modeling of high performance computing (HPC) is enhanced through a very significant MRI grant from NSF for a hybrid HPC environment.
 
The department also has a core research component in complexity theory, fault diagnosis, mathematical theory of computation, algorithms and their applications to molecular computing and bioinformatics. Work in the area of artificial intelligence concentrates on learning and reasoning under conditions of uncertainty and insufficient knowledge and resources.
 
The majority of our research projects have being funded by the National Science Foundation (NSF), the Defense Advanced Research Projects Agency (DARPA), Department of Defense (DOD), the National Institutes of Health (NIH), the National Institute of Standards and Technologies (NIST) and the Office of Naval Research. 
 
Much of the department’s research work is carried out by faculty and students of the Center for Data Analytics and Biomedical Informatics (DABI) and the Center for Networked Computing (CNC). The projects are interdisciplinary and involve faculty and students from departments as diverse as Engineering, Biology, Chemistry, Statistics, Mathematics, Operational Research, Radiology, Neurology, Pathology, Pharmacology, and Psychology.
