My field of interest is to enhance scientific knowledge and application value of various natural products. I have previously worked with flavonoids and polyphenols from terrestrial plants and in recent years, my focus have been on natural products from the marine environment.

Research areas:

  • Qualitative and quantitative analysis of polyphenols and pigments from marine sources (marine angiosperms, seagrasses, algea)
  • Chemical analysis of marine sponges collected in Norway
  • Bioprospecting and search for novel compounds
  • Chemical ecology and biosystematics studies

Because of the structural diversity, characterization of natural products requires an integrated analytical approach including optimized extraction techniques, multiple steps of chromatography, High Resolutions Mass spectrometry (HRMS) and high field NMR analysis.




KJEM235 https://www.uib.no/emne/KJEM235    (10 ECTS)

Mål og innhald

Emnet skal gje ei forståing av korleis ein kan analysere organiske sambindingar ved hjelp av spektroskopiske metodar som infraraud-(IR), ultrafiolett-synlig (UV-Vis) og kjernemagnetisk resonans-(NMR) spektroskopi, samt massespektrometri (MS). Emnet er spesielt konsentrert om tolking av data, men ei grunnleggjande forståing av dei ulike analysemetodane blir også vektlagt. I kurset vil hovudfokus ligge på metodane NMR og MS.


B.Sc. and M.Sc.-projects:

- Different chemical topics within analysis and bioprospecting of marine sources (micro- and macroalgae, seagrasses, aquatic angiosperms, sponges)
