Timothy W. Randolph
Ph.D., University of Oregon, Mathematics, 1990.
M.S., University of Oregon, Mathematics, 1984.
B.S., University of Puget Sound, Mathematics, 1982.
Current research focuses on processing, classification and analysis of high-dimensional and/or functional data output from protein mass spectrometry, genetic assays and a variety of spectroscopies and imaging modalities. Other interests include methods for the analysis of networks used to describe gene and/or protein interactions. Additional experience includes lead statistician on biomarker validation studies within the NIH Early Detection Research Network.
A career in mathematics began with a focus on functional analysis, spectral theory of operators and Fredholm theory. Teaching experience as an associate professor includes over 20 different course titles in undergraduate and graduate mathematics and advising for undergraduate and graduate students.
My original research evolved into the study of mathematical control theory, including the study of dynamics and stability of infinite-dimensional linear control systems (those described by system of partial differential and delay equations). An NIH career-transition award provided the opportunity to shift from a research emphasis in pure mathematics to the development of methods for analysis, computation and models of biological/biomedical data.
