Associate professor and director, Biomedical Imaging Lab

Homepage

George Zouridakis is assistant professor and director of the Biomedical Imaging Lab with the University of Houston's (UH) Department of Computer Science. He is jointly appointed as adjunct associate professor with both the Bioengineering Department at Rice University, and the University of Texas Health Science Center at Houston.

Dr. Zouridakis' work with UH's Biomedical Imaging Lab includes the research of computational biomedicine and bioimaging, with specific emphasis on functional brain mapping and the interplay between neurophysiological signals and information processing in the brain. The Lab's goal is to develop new computational tools for the diagnosis and treatment of neurological disorders, as well as the characterization, quantification and visualization of cancerous tumors.

Mentor to a number of master's degree students, Dr. Zouridakis has written two biomedical textbooks and numerous journal articles, and has delivered guest lectures at universities and conferences worldwide. He is a member of the Keck Center for Computational Biology and sits on the executive committee of the Society of Electrical and Electronics Engineers.

Dr. Zouridakis holds a PhD in electrical engineering from the University of Houston.

Research interests

Dr. Zouridakis’ research areas include biomedical imaging, computational biomedicine, functional brain mapping, and biosignal analysis and modeling.

Research projects

Functional brain mapping

The goal of this research is to identify areas of the brain that are involved in higher cognitive functions -- such as memory and language -- in normal volunteers and patients.

Computational tracking of human learning

This project team is developing computer models of humans learning complex tasks that involve strategic and visual-motor components.

Visualization tools for MRI-guided hyperthermia

This project’s goal is the development of computational tools and graphic user interface for planning, localization, monitoring and dose verification in MRI-guided hyperthermia procedures.

Quantification of tumor parameters by PET

Focus is on the identification of parameters for monitoring tumor blood flow and glucose metabolism changes in tumors following therapy and development of methods. This will allow the medical community to measure antiangiogenic changes in human tumors.

Advanced techniques for biosignal analysis

This research explores the use of independent component analysis to obtain improved estimates of the ' true' brain response to external auditory stimuli. This will provide insights into how the healthy brain processes information, and possibly help with the diagnosis, categorization and treatment of schizophrenia patients.

Research partners

Dr. Zouridakis partners include researchers from Bonn University, Fachhochschule L--the MD Anderson Cancer Center, Rice University, the University of Crete, the University of Texas Medical School-Houston, and Yale University. His research is funded by the National Institutes of Health, the Texas Higher Education Co-ordinating Board and Shell Foundation.
