Marin ressursforvaltning, fiskeri- og oppdrettsforvaltning og utvikling i verdens fiskerier

Among the different evolutive forces, connectivity and local adaptation are two contrasting evolutionary forces highly influencing the population structure of a species above their distribution range. In my PhD I am stuttering the population structure of Cyclopterus lumpus looking at both connectivity and local adaptation in order to better define the different stocks of this species and predict the impact of translocation methods, domestication and climate change on its population structure.

Reseach Interests:

My  interest is to discover new bioactive molecules for drug discovery, mainly from marine bacteria. A crucial step in the discovery-process is the identification of known or unknown molecules which is heavily relying on HPLC-HR-MS2. Beside anti-cancer and other pharmaceutically relevant bioactivities, anti-bacterial activity and MoA is a strong interest of mine. Identified candidates are then isolated and their structure is elucidated by NMR. Another project I am working on delas with the screenig of marine rest-raw-material hydrolysates for new neutraceuticals to combat the metabolic syndrome.
