Sidney Resnick is interested in inference about asymptotically defined quantities which describe models beyond the range of the data. Examples include: asymptotic sufficiency of rank transformations; tail inference and estimation; and models of dependence for nonnormal vectors and processes, especially those models which can be empirically validated. Resnick’s interests range from data analysis of Internet and finance data to abstract inference for quantities only evident after a limiting operation.
David Ruppert currently pursues research on (1) the calibration of models used by environmental engineers, (2) fitting statistical models when variables have been measured with error, (3) the use of splines in statistical modeling, and (4) Bayesian computations. He has worked on a variety of applications including estimation of the term structure of interest rates, estimation of the concentrations of pathogens in drinking water supplies, biostatistics, and the metamodeling of cluster tools used in semiconductor manufacturing.
Bruce Turnbull is interested in methodology and applications of statistics. Particular topics include statistical quality control; reliability; biostatistics; group sequential design and analysis; adaptive designs; interim monitoring of clinical trials; statistical evaluation of diagnostic procedures; survival analysis; and monitoring spatial patterns of disease incidence.
Gennady Samorodnitsky is interested in statistical analysis of stochastic models, particularly with tail estimation, both in one and several dimensions. He is also interested in estimating the length of memory, in both time domain and in spectral domain.
