I completed my PhD in 2014, working in Laboratoire Navier (Universit・Paris-Est, France) on the rheology of bubble suspensions in complex fluids. I then joined the Manchester Centre for Nonlinear Dynamics (University of Manchester, UK) for my first postdoctoral research position, during which I investigated viscous fingering instabilities in a channel with a compliant boundary. I am currently a postdoctoral researcher at PMMH (ESPCI, France), where I work with Anke Lindner and Sandra Lerouge on the elastic instability of polymeric solutions in curved microchannels. My short visit at OIST is part of a collaboration with the Micro/Bio/Nanofluidics Unit in which we aim at characterizing the elasticity-induced secondary flows that develop for polymeric solutions in curved microchannels. Outside work, I like swimming and walking, two perfect hobbies to enjoy beautiful Okinawa!
Joshua Cardiel – Visiting Researcher (Summer 2014)
I earned my PhD in Mechanical Engineering and Nanotechnology at the University of Washington, Seattle, USA. My PhD research focused on complex fluids and microfluidics. Currently, I'm a visiting researcher at OIST. I'm investigating how different ionic solutions interact with micellar solutions by using microfluidics. I am also studying the behavior of non-ionic surfactant solutions at different temperatures to induce the formation of biocompatible gel-like materials.
Outside my research, I spend time watching movies (I'm cinephile), working out and doing any kind of outdoor activity!
