I work at the Sea Lice Research centre with a focus on the host-parasite interaction of salmon louse (Lepeophtheirus salmonis) and Atlantic salmon as a host. We identify secretory proteins that are deposited from the lice onto the salmon to dampen immune responses.

Techniques that we use includes: transcriptomics, in situ bybridization, histology, SEM, functional studies with primary leucocytes and gene knock down (RNAi) etc

I teach in the aqua medicine program: Vertebrate zoology in BIO101 and histopathology (BIO275)
