In 2014, I moved from University of Washington to start my new lab at OIST on micro- and bio-fluidics, and anything squishy! Outside work I enjoy the beach, yoga, and exploring/learning more about Okinawa, a perfect work and living paradise. If you are interested in working with us, feel free to contact me or any unit members.
I completed my Ph.D in Physics in 2002 under the supervision of Dr. Jeff Odell from the University of Bristol (UK) and Prof. Alejandro Muller from Simon Bolivar University (Venezuela). Following postdoctoral research positions first at Bristol, then at MIT with Prof. Gareth McKinley, I obtained a Marie Curie International Research Fellowship which I carried out at the University of Porto (Portugal). I joined OIST as Group Leader for the Micro/Bio/Nanofluidics (Shen) Unit in September 2014. Away from the lab, my main activity is road cycling. In Okinawa I’m also keen to take up sea kayaking and scuba diving.
I completed my PhD in Chemical Engineering in 2020 under the supervision of Prof. John Tsamopoulos and Yannis Dimakopoulos from the University of Patras (Greece). My research was focused on the dynamic analysis of elastic and interfacial instabilities in flows of complex fluids, such as polymer solutions and melts, gels, suspensions, soft media, and biological fluids. During that time, I also worked on the development of a finite element technique (PEGAFEM-V) for the simulation of 3-dimensional non-Newtonian flows with multiple free surfaces, and the derivation of constitutive laws for thixotropic elasto-visco-plastic materials. I joined the Micro/Bio/Nanofluidics unit in 2021 as a postdoc to combine my theoretical background with novel microfluidic experiments, aiming at a deeper understanding of the rheological response of complex fluids. Away from the lab, I enjoy travelling around the world, recreational sailing, camping, and cooking.
I earned my Ph.D in Mechanical Engineering from the University of Massachusetts under the guidance of Prof. Yahya Modarres-Sadeghi. My work there centered on studying fluid-structure interactions (FSI) of multiple-degree of freedom systems for applications in the offshore wind energy sector. Topics included vortex-surface alignment for flexibly-mounted prisms, suppression of vortex-induced vibrations, and biomimetic ultrasound generation via flow-induced oscillations. During this time I also had the opportunity to collaborate with NASA Langley to investigate potential uses of their contactless SANSEC sensor technology. I joined the Micro/Bio/Nanofluidics unit as a postdoc in May 2019 and look forward to applying my FSI background to more exotic flexible and biological structures in complex flow! While at Okinawa I want to improve my drawing, pick up some languages, and get into open water swimming.
I completed both my B.Sc., in 2013, and Ph.D., in 2018, in Physics at the University of Western Ontario in London, Ontario, Canada. My Ph.D. research was supervised by Prof. John de Bruyn. My research was focused on the development and use of a novel tool – a vibrating wire rheometer – for measuring the viscoelastic properties of complex fluids at high frequencies. In 2017, I completed a 4-month research internship here in the Micro/Bio/Nanofluidics Unit where I studied a flow instability of graphene oxide dispersions. Following the conclusion of my Ph.D., in October 2018 I returned to OIST as a postdoctoral scholar in the Micro/Bio/Nanofluidics Unit. My research interests span all things related to rheology and non-Newtonian fluid mechanics. I am especially interested in developing innovative new approaches for studying complex fluids. At OIST, I will be exploiting our unique ability to construct microfluidic channels out of glass to study the flow of complex fluids around confined cylinders. Besides work, I enjoy watching and playing hockey and exploring this island, both above and below the sea.
After completion of my MSc in Food Technology at Wageningen University (NL), I moved to the University of Bath (UK) to pursue my PhD in Chemistry. The project led by Prof. Karen Edler and Prof. Janet Scott focused on the characterisation of the structural-property relationship of colloidal cellulose nanofibrils in bulk and across liquid-liquid interfaces. I also performed scattering techniques (X-rays and Neutrons) and (non)linear rheology to yield structural information of the colloidal state. I joined the Micro/Bio/Nanofluidics unit as a postdoc in January 2020 to link rheological behaviour and structural properties of complex fluids in microfluidics. Besides lab-related activities, I enjoy playing guitar, cycling, open water swimming, and exploring the tropical island.
Shivani Sathish (OIST POC Fellow)
I completed my Bachelors in Technology in Genetic Engineering at SRM University, India. I spent six months at OIST as an intern, working on my bachelor thesis in Prof. Tomoyuki Takahashi’s unit. After my internship, I joined OIST as a PhD student in January, 2015. I joined the Micro/Bio/Nanofluidics Unit to complete my third laboratory rotation in September, 2015 where my work will involve multi-composite surface patterning to create functional neural networks. Having worked on biological experiments in the past, I am excited to start my work in this new field. Outside work, I enjoy learning Japanese, exploring life underwater, hiking in Okinawan forests and experimenting with new cuisines.
Tatiana Porto Dos Santos
I completed my Ph.D in Food Engineering in 2021 under the supervision of Prof. Dr. Rosiane Lopes Cunha from the University of Campinas (Brazil) in collaboration with Prof. Patrick Tabeling from ESPCI Paris (France). My Ph.D. research was focused on the development of an emulsion stability analyzer based on microfluidics. Earlier in my MSc, I studied the digestibility of colloidal gel-like systems and built a semi(dynamic) digestive prototype. I joined the Micro/Bio/Nanofluidics Unit as a postdoctoral researcher in September 2021 to apply my current background in rheology, microfluidics and gelled systems in the development of new food structures. Outside the lab, I enjoy travelling and can’t wait to explore Okinawa.
I earned my PhD at the University of Rome “Tor Vergata” in Analytical Chemistry under the supervision of Prof. Fabiana Arduini and Prof. Danila Moscone. My research activity is mainly focused on electrochemical sensors and biosensors development for metals, ions and biomarkers detection in biological matrix such as sweat, urine and serum, or bacteriological species in water and foods. During the years I obtained specific knowledge of spectrophotometric and electrochemical techniques (i.e. impedance spectroscopy, amperometry, cyclic voltammetry and potentiometry) and skills on the use of nanomaterials (i.e. Carbon Black, gold nanoparticles), and of the screen-printing technology. I joined the Micro/Bio/Nanofluidics unit in September 2021 to increase my research activity on biosensors development combining it with microfluidics applications. Besides this I like playing tennis, football and doing interesting activities in Okinawa wonderful island such as bicycling, snorkelling, and hiking.
I am originally from Seattle where I received my undergraduate degree in Applied and Computational Mathematical Sciences from the University of Washington. Although my background is in math I am fascinated with the more tangible sciences. I recently moved to Okinawa from Hawaii and I brought a few ukuleles with me. I have a wide range of artistic and physical hobbies but my favorites are woodcarving, hiking/camping, snorkeling, bicycling, music, chess, traveling and general goofiness. OIST is quite an amazing place and I am grateful to be here.
San To Chan (
I received my BEng (Engineering Science) from the University of Hong Kong. I enjoy experimenting with different swirling flow instabilities, such as vortex breakdown and edge fracture. When I am not working, I play with the cats inside and outside my apartment, they are so cute and fluffy.
Ainash Garifullina (
I received my BSc degree in Chemistry from Nazarbayev University in Astana, Kazakhstan. During my undergraduate, I’ve been mostly interested in natural product and macromolecules synthesis, which is why I was planning to work in an organic synthesis lab. However, after my rotation in Micro/Bio/Nanofluidics unit, I got more excited about plasmonic biosensing using microfluidics. So, I decided to join this unit for my thesis project and to use microfluidics in order to address a number of fundamental issues related to plasmonic materials. Outside work, I enjoy spending time with my friends, roaming around the island, and discovering new exciting things about Japan.
I was born and grew up in this sub-tropical island. I support the unit members with administrative works and enjoy working with this very interesting group at OIST. Besides work, I like dancing and traveling. I am also interested in languages.
