Professor Hoffmann has coauthored or authored over 200 papers applying statistical methods to biomedical problems. He is an expert statistical methods for neuroimaging, connectionist neural networks for modeling addiction, time series analysis, statistical methods for epidemiology and analysis of variance involving repeated measures. He has investigated binary time series, graphical methods for identifying nonlinear binary time series, categorical nonlinear time series and models for the pulsatile secretion of insulin. He has extensive experience with the design and planning of community studies. He also is interested in cardiovascular epidemiology and has investigated the effects of mediating factors such as alcohol, body fat distribution and hormone profile on the development of occlusive heart disease.
Professor Hoffmann serves as the Biostatistician for the Medical College
of Wisconsin General Clinical Research Center and is a collaborator on
a number of NIH funded projects with investigators at the Medical College
of Wisconsin. He has been the president of the Milwaukee chapter of the
American Statistical Association. Professor Hoffmann received the Outstanding
Service Award from the Milwaukee Chapter in 1988. He is certified by the
American College of Epidemiology.
