Brief biography

Dr. Janice Lawrence completed her BSc (Marine Biology) and PhD (Biological Oceanography) at Dalhousie University. Her PhD thesis investigated the source and dynamics of algal toxins in cultured shellfish. She completed a post-doctoral fellowship at UBC studying the role of viruses in phytoplankton ecology, and received an NSERC University Faculty Award to join UNB in 2003.

Janice’s current research focusses on the biological interactions that regulate toxin-producing cyanobacteria. She also collaborates with researchers at the University of Bergen studying the co-evolution of viruses and their hosts, and co-supervises students studying virus and viroid infections in crop plants at the Fredericton Research and Development Centre.

In her spare time Janice is building an off-grid cabin along the Wolastoq, and loves outdoor adventures including skiing, biking, hiking, paddling and swimming.
