My main research area is Statistics, ranging from theory to applications with the latter primarily in ecological and biostatistical applications. My current work is focused primarily on measurement error in time series and longitudinal data, with particular interest in population dynamics, and methods associated with misclassification (in in collaboration with colleagues at the University of Oslo Medical School). Other areas of continuing interest include estimating distributions in the presence of measurement error, estimation in two-stage models (including random coefficents and meta-analysis and regression/synchrony in spatial-temporal settings.
