I am interested in non-parametric regression and developing new techniques to analyse functional data. My PhD. was related to the study of wavelets, in particular the denoising of functions and imputation. Since then I have continued my work on regression (or drawing a curve that goes near a set of points) through collaborative work aiming to improve the method of radiocarbon dating.
