My interests include polymer and interfacial sciences, and I look forward to branching into microfluidics and responsive particles during my tenure in the MBN unit. I have most recently spent my free time studying Japanese, practicing martial arts, and getting my swimming abilities ready for Okinawa's shores.
Sébastien Ricoult – Research Scientist II in Illumina, Cambridge
I completed a neuroengineering Ph.D. at McGill University in Montreal, Canada and joined the Micro/Bio/Nanofluidics Unit as a postdoctoral scholar in May 2015. My past work was aimed at developing micro/nanotechnologies to study axonal navigation. These included a nanopatterning-based haptotaxis assay to identify gradient geometries most apt to guide neurons to desired targets. To become a well-rounded micro/nanotechnologies engineer, I will now complement my surface patterning skills with experience in the exciting field of microfluidics.
Be it jelly giggling, rod climbing, marshmallows stretching, waves crashing on shore, clouds in the sky, the swirl of a galaxy or milk mixing into coffee...I am inspired by the flow and deformation of matter. And I would have to be because, as anyone who has used a rheometer knows, measuring rheological properties with parallel plates is relatively uneventful, but it fascinates me none the less.

Here at OIST, I use microfluidic techniques to study the flow behavior and the phenomenon of flow-induced structure formation of these self-assembling systems in extension. I am very grateful to be a part of Shen Unit and it is a great opportunity to learn new experimental methods in a unique research environment. Away from the lab, I enjoy playing squash, practicing yoga and outdoor activities such as climbing, hiking and snorkeling in beautiful Okinawa.
I am a PhD student in Physics from The University of Western Ontario in London, Ontario, Canada. My PhD research is focused on rheology and the development of new experimental tools for studying the microscale structure of complex materials. I started an internship in the Micro-Bio-and Nanofluidics unit in January 2017. My research here is focused on studying the instability that forms in certain flows for Graphene-Oxide suspensions. This is observed in large-scale flow geometries, however, we are also interested in seeing if the same instability forms in microfluidic channels and intend on fabricating microfluidic devices to study this phenomenon. This internship will introduce me to new aspects of rheology and fluid mechanics that are outside the scope of my PhD, and I am grateful to OIST and Professor Shen for allowing me this tremendous opportunity.
