Former Members

Postdoctoral Scholar

Stefano Olivieri (2020 May - 2022 Apr)
I was born and grew up in Genoa, Italy. I graduated in Mechanical and Aeronautical Engineering and completed my PhD in Fluid Dynamics and Environmental Engineering at the University of Genoa. My background mainly concerns with fluid-structure interactions (FSI) and particle-laden flows. In May, 2020 I joined the Complex Fluids and Flows Unit at OIST as a Postdoctoral Scholar. My current research deals with FSI and complex fluids with a particular focus on turbulent flows, investigating these problems by means of large-scale numerical simulations. Topics include the interaction of flexible fibers with turbulence and energy harvesting from environmental flows, as well as the dynamics of particle suspensions and Non-Newtonian fluids. Beside work, I enjoy hiking, playing football, watching movies and discovering Okinawa and its culture.

Alessandro Monti (2020 April- 2022 Aug)
I am a Postdoctoral Researcher at Okinawa Institute of Technology (OIST, Okinawa - Japan), in the Complex Fluids and Flows Unit. My research focuses on the study of multiphase flows, turbulent flows and Non-Newtonian fluids with the goal of characterising their basic phenomena originated by their multi-physics and multi-scale nature. Complex fluids are linked to many industrial applications ranging from pharmaceutical processes to personal care and food industries, including plastics and polymers more in general. The study is tackled via numerical simulations. A new code with novel methods to model such complex physics is written to run on CPU and GPU clusters with modern parallelisation techniques.

Rotation Students

Giulio Foggi Rota (2021 Sep-2022Apr)
During the last few years, earlier as an undergraduate and now as a graduate student, I have been enrolled at the Politecnico di Milano, located in northern Italy, my homeland. While attending the Master in Aeronautical Engineering, I have developed a strong curiosity towards fluid dynamics. I am currently working at my Master's thesis under the joint guidance of members from both OIST and PoliMi. Since it is almost time for me to make a choice concerning the Ph.D., I hope this experience will help me understand if turbulence and flow control truly are the fields I want to focus on in the years to come. When I shut down my laptop, I enjoy listening to classical music, hiking, swimming and sailing.    

Fabian Hillebrand (2022 Jan-Apr)
After completing my first year in university studying Physics at ETH Zurich, I switched to Computational Science and Engineering completing both my bachelor's and master's degree specializing in Chemistry and Physics, respectively. In my master's thesis I implemented an algorithm for simulating high-resolution scanning tunnelling microscopy (HR-STM). At OIST, I want to broaden my understanding of fluid mechanics. I hope my background in HPC will be useful for my lab rotation in the Complex Fluids and Flows unit.

Ilhem Nadia Rabehi (2022 Jan-Apr)
I am interested in sustainable and green energy generation and storage, I also like sewing and hiking.

2020 Arab Program for Sustainable Energy Youth intern , RCREEE, Egypt
2019 RE system modelling research intern, CDER, Algeria
2017-2019 Master in energy engineering, Pan African University PAUWES , Algeria

Morie Koseki (2021 Sep-Dec)
I majored in mechanical engineering at Akita University and studied the deformation of long flexible structure in the space. My current interest is the interaction of flexible structure with fluid, so working in this unit will give me some points of view for my future PhD thesis. I am also looking forward to snorkeling in Okinawa.

Jean-Paul van Woensel (2021 Sep-Dec)
I was born and raised in Nuenen, the Netherlands. I completed my master's degrees in Applied Physics and Science Communication at the Univeristy of Technology in Eindhoven. For my master thesis, I developed a tracking algorithm which I used to get statistics on the flow of droplets in dense binary emulsions. Besides this, I also did work on the electric response of superfluid helium and its reversibility. I have a broad interest in many physics topics, but I specialized in fluid mechanics in my master. I hope my time at the CFF unit will help me find what research I really want to do the upcoming years at OIST. In my spare time, I enjoy speedrunning video games and hiking.

ELuke Collyer-Hoar (2020 Sep-Dec)
As part of my Mathematics Masters at Imperial College London, my thesis focussed on finding solutions to the Dirac equation in the presence of abelian BPS monopoles using the Nahm transform. I also undertook a project in which I attempted to find solitary waves in an inviscid fluid between two horizontal plates with an electric field passed between. At OIST I hope to develop my work on fluids and as such my first lab rotation in the “Complex Fluid and Flows” unit is concerned with producing a numerical simulation of a fluid between two elastic solid boundaries with a periodic pressure difference. In my spare time I enjoy reading history and philosophy, playing and watching football, and in general keeping active.

Hideyuki Yoshimura (2020 May-Aug)
I studied computer science at the University of Electro-Communications, and my thesis was focused on computational model of neural circuits and their numerical simulation. At OIST, I hope to acquire a broader knowledge that I can use in my specialty. Although fluid mechanics is out of my field, I believe that working in this unit will give me a good experience, because physics is often related to neuroscience through several areas, such as information theory.

Patrick Clark (2020 Jan-Apr)
I studied in the University of Sheffield, with a thesis focused on modelling aneurysm formation at the terminus of the basilar artery-posterior cerebral artery junction. I looked at the formation of wall shear stress at the walls adjacent to a bifurcating flow; considering changes to the rheology of the blood mimicking fluid, the geometry of the physical model plus steady and unsteady state flow regimes. I undertook several smaller fluid mechanics project including a 2D study of airflow over a step, looking at the properties of recirculating flow in front of the step and calculating the reattachment point of the flow downstream from the step. At OIST I hope further develop my work on the mechanics of fluid flows, and as such my first lab rotation in the “Complex Fluids and Flows” unit is concerned with producing a numerical simulation of a turbulent fluid flow over an oscillating cylinder aligned perpendicular to the flow direction. In my spare time, I enjoy playing and watching football, as well as playing other sports and keeping active.
