LIGHT Dr. Mark Martinez’s research activities focus essentially on the behavior of papermaking fibre suspensions. These suspensions often exhibit complex behavior not seen in ordinary fluids such as water. Dr. Martinez uses both novel visualization techniques, such as positron emission tomography (PET) and pulsed ultrasound Doppler anemometry, and computational fluid dynamics to help elucidate the mechanism by which these suspensions flow. Dr. Martinez is a member of the Institute of Applied Mathematics and has active collaborations with researchers in Mechanical Engineering, Mathematics and TRIUMF.
