Professor Jonathan Morrison holds the chair of Experimental Fluid Mechanics in the Department of Aeronautics at Imperial College. He received his and PhD from the University of Durham and became a member of faculty at Imperial College in 1991. His recent work has focussed fundamentals of wall turbulence including coherent structures and their relation to changes in imposed length-scale, energy transfer and pressure fluctuations. Novel approaches to flow control involve Electro-Active Polymers (EAP) both as actuators (GR/S20994, PI), and as surface-pressure sensors (EP/C535847, PI), including ink-jet printing techniques (EP/F004435, PI). Travelling surface waves for drag reduction are being developed with support from Airbus, QinetiQ and EADS-IW. Novel algorithms have been formulated (EP/E017304, CI) for real-time feedback control using wall-based sensing and actuation. High-frequency pulsed jets are being used for the control of separated flows with support from Ferrari S.p.A., EPSRC (EP/I005684, PI) and Imperial Innovations. Recent work involves fundamental studies of the effects of large roughness on turbulent channel flow (EP/D037166, PI) and turbulent boundary layers (EP/I037938, PI) and instabilities as part of the LFC-UK Programme Grant (EP/ I037946, CI). Previously, he has been Visiting Fellow at MAE, Princeton University. In 2006, he chaired the Scientific Committee for the IUTAM Symposium, Flow Control and MEMS in 2006. He is currently a member of the Aerodynamics Specialist Advisory Group of the ATI and also sits on the advisory board of the UK Turbulence Consortium. He chairs the Management Board of the National Wind Tunnel Facility, http://www.nwtf.ac.uk/html/index.html, funded by EPSRC and the ATI. He led an exhibit at the Royal Society Summer Exhibition, 2014 "Smart Wing Design: Science Imitating Nature".
