Biography Tormod Næs

I have a PhD i Statistics from University of Oslo . My experience covers both method development and applications within a large number of areas; the most important being spectroscopy, process optimisation, product development and sensory science. The most important publications I have been involved in are the more than 225 peer review papers published in journals related to statistics, chemometrics, food science, sensory science, spectroscopy and analytical chemistry. I have also co-authored and co-edited 6 books in the areas of chemometrics, statistics and sensory science. I have supervised more than 20 students to final PhD degree and have been the European editor of Journal of Chemometrics (3 years) and Associate editor of Technometrics (2 years).I have extensive experience as project leader and as chairman of international conferences.

Tormod Næs has 215 publications at Nofima:
