Kjemometri og analytisk kjemi.

Jeg underviser kursene KJEM110 Kjemi og energi, KJEM325 Multikomponentanalyse og FARM301 Farmasøytisk forskningsmetodikk. I tillegg er jeg involvert i det internasjonale masterprogrammet European Master in Quality in the Analytical Laboratory (EMQAL), der jeg underviser to kjemometrikurs.

 

Masteroppgaver gis innen kjemometri og analytisk kjemi, gjerne i samarbeid med eksterne industripartnere eller andre forskningsinstitusjoner.  Eksempler på tidligere oppgaver er
