Eliot Fried


Group Leader



Ryohei Seto

I am interested in particle-scale dynamics and rheology of colloidal dispersions. I joined the Mathematical Soft Matter Unit as Group Leader in January 2015. Previously, I was a research associate at the Benjamin Levich Institute of The City College of New York, collaborating with Jeffrey F. Morris and Morton M. Denn. I also worked as postdoctoral fellow at the Max-Planck-Institute for Polymer Research (Germany), Technical University Munich (Germany), Laboratoire de Génie Chimique in Toulouse (France), and Laboratoire de Physique des Solides in Orsay (France). I received my PhD in physics from Ritsumeikan University in 2006. I am the recipient of Journal of Rheology Publication Award 2015.


Postdoctoral Scholar



Giulio Giusteri

I received my PhD in Pure and Applied Mathematics in 2012 from the Università di Milano-Bicocca (Italy). I joined the Mathematics, Mechanics, and Materials Unit at OIST after postdoctoral research at the University of Washington (USA) and at the Università Cattolica del Sacro Cuore (Italy).
My research focuses on applying mathematical structures, both theoretical and computational, to describe and understand basic physical phenomena, ranging from the mechanical behavior of soft matter to the dynamics in disordered quantum networks to general systems of interactions. Answering questions like "What's the best mathematics for talking about this phenomenon?", I want to enhance our understanding of nature.



Stoffel Janssens

I’m Belgian and I obtained a Master in Physical Chemistry at the Free University of Brussels. Later I obtained a PhD in Physics at Hasselt University in Belgium where I also performed a two year postdoc. During my PhD and first postdoc I specialized in diamond growth, device fabrication and electronic measurements. After obtaining a Japanese Society for the Promotion of Science (JSPS) fellowship I worked two years as a postdoc in the National Institute for Materials Science (NIMS) in Tsukuba where I more deeply investigated diamond growth. In November 2015 I started working in the Fried Unit. At OIST I will also perform diamond growth and characterization. In parallel I’m working on non-coalescent droplets hovering on liquid substrates. A list of work I’ve been involved with can be found on google scholar.


Johannes Schoenke

I received my PhD in Theoretical Astrophysics from Heidelberg University. Before coming to OIST in 2015, I worked at the Max-Planck-Institute for Dynamics and Self-Organization in Goettingen. My interests include theoretical mechanics of continua, and dynamics of complex systems. In the last years, I worked on several theoretical problems, including planet and star formation, signal propagation in nerve fibers, hydrodynamical turbulence, diffusional growth, and frustrated magnetic systems. Recently, I investigate assemblies of magnetic balls, the analogy of point dipoles and mechanical gears, and further the mechanics of unstretchable sheets.



Yoichi Takato

My research interests lie primarily in the field of mechanics and dynamics of nanomaterials. I joined OIST in 2015 and my research here focuses on elastic properties of a Moebius band made of a 2D material. I am currently working on how a nanoscale Moebius band can be formed by bending and twisting a graphene nanoribbon using molecular dynamics.
I earned my Ph.D. in Physics in 2015 at State University of New York at Buffalo. During my Ph.D. period, I studied the solitary wave propagation in a granular chain and the mechanical interaction between colliding nanoparticles. Prior to my Ph.D. degree, I had worked as a mechanical engineer for over seven years in a vacuum pump manufacturer.

Research Technician


David Vazquez

I received my PhD in Applied Physics from the University of San Luis Potosi in Mexico, where I studied the self-assembly of semiconductor nanostructures in III-V systems, by molecular beam epitaxy technique, and its application to semiconductor devices.
I also have experience in the machining of high precision parts, by using the machines in the workshop.In general, I like to use machines. As a Research Technician in the Mathematics, Mechanics, and Materials Unit at OIST
, I have the opportunity to learn a very wide variety of exciting experimental techniques, and I am also supporting the researchers of the unit in the performance and set up of experiments.


Ph.D. Student



Vincent Chan

I have joined Fried's unit since February and am currently studying configurational forces within the context of particle systems.


Special Research Student


Vikash Chaurasia

I completed my Undergraduate and Masters degree in Department of Mechanical Engineering from IIT Kanpur, India in 2012. I joined University of Houston for my Ph.D. in 2013 and I joined Professor Fried’s group at OIST as an exchange student since September 2015. My core interest lies in continuum mechanics, variational calculus and Hamiltonian dynamics. I am keenly interested in studying interesting biological processes from mathematical perspective.


Research Intern



Ching-Hsiu Hsu (April - August 2016)

I completed my undergraduate studies at University of California, Berkeley in Molecular and Cell Biology, Neurobiology, and Physics. Before starting graduate school in the fall, I have taken up an internship in the Fried Unit to study the dynamics of liquid droplet breakup. The goal of my project is to use data from high-speed cameras and theoretical methods to characterize the fragmentation and diffusion process of ink droplets in water.
