Alfonso Albano: Research Interests


Nonlinear Dynamics Group 2001-2002:

Alfonso Albano; Peter Brodfuehrer (BMC Biology Department); Paul Rapp (Medical College of Pennsylvania - Hahnemann University); Chris Celluci (BMC Ph.D. '98, now teaching at Ursinus College); Steve Hess (Ph.D. student); Erin Schwamb '02.

Alfonso M. Albano

Marion Reilly Professor of Physics Emeritus. B.S., University of Philippines; M.S., University of Iowa; Ph.D., State University of New York at Stony Brook (1969). 
Nonlinear Dynamics, Chaos.

Developments in nonlinear dynamics during the past four decades or so have made available some techniques for the analysis of complex spatial and temporal behavior. We use these techniques in the study of biomedical data. Current projects are: (1) Development and refinement of algorithms for the calculation of quantitative measures of complex spatial and temporal behavior and for the identification and classification of complex systems; (2) charaterization of human  electroencephalographic (EEG) signals in connection with studies of brain traumatic injury; and of vasomotion in monkeys in connection with studies of diabetes,  (3) studies of the feasibility of using measures of complex behavior as diagnostic tools, to characterize changes in behavior induced by pathology or changes in experimental conditions.  These projects are being undertaken in collaboration with colleagues at the Uniformed Services University of Health Sciences, the National Institutes of Health, and at Mindanao State University – Iligan Institute of Technology in the Philippines.
