On Feb. 8, Dr. Qianhong Wu at Villanova University, came to UMBC and gave the ME faculty and students a research seminar.  Dr. Wu focused the first part of presentation on his research of using lubrication theory and transport in porous media to explain how friction can be dramatically reduced in various applications from microscale level when red blood cells travelling in narrow capillaries to macroscale level of snowboarding.  The second portion of his presentation was on how the cerebrospinal fluid (CSF) transport in porous media acts as a damping component to resist external physical impacts in humans.  We all enjoyed the presentation very much.
