Professor Blanchette is an applied mathematician primarily interested in problems involving fluid dynamics. A large portion of his research is concerned with problems related to sedimentation. The accumulation patterns, erosion potential and transport properties of such systems are of geophysical and environmental interest. He also studies systems where two immiscible fluids are present and surface tension plays a significant role, such as drops, bubbles and micro-fluidic devices. Professor Blanchette's approach is mostly theoretical and numerical, and he also values interactions with experimentalists so as to paint as complete a picture as possible of a given physical system.
