Knut Woltjen (Associate Professor)Knut Woltjen

Knut grew up in rural Alberta (Canada), canoeing on the lake, or building tree forts in the forest (with a healthy dose of LEGO on rainy days). More a product of this natural environment than despite it, his curiosity in life science research grew – eventually leading to a career in biotechnology.
