Unit Members


Amy Shen
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.

Group Leader

Simon Haward
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.

Postdoctoral Scholars

Vincenzo Calabrese
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.

During my time at OIST, I look forward to discovering Okinawa and other regions of Japan.

Davide Califano
As an extroverted and peaceful character, I enjoy working in a collaborative and sharing environment. During my initial studies I have soon realised that I was interested in the relationship between chemistry and life, so I enrolled for a molecular biology MSc at Pisa University (Italy). There, I enjoyed studying life-science subjects including DNA biotechnologies, microbiology, and biochemistry. In 2017, I started a Ph.D. at the university of Bath on the development of novel cellulose/enzyme hybrid materials. My research project concerned the design of biodegradable materials for mitigating the use of micro-plastics. After my PhD I worked as postdoctoral scientist at Naturbeads Ltd (Bath - UK) where I have focused my research on the biotech applications of bio-based soft materials. Lead by the desire to work in the field of sustainable technologies, I decided to start the Proof of Concept (POC) innovation program here at OIST. My project aims at exploiting microalgae for enhancing sensory characteristics of meat substitutes. Beside work, I love cooking, hiking, taking pictures and travelling so I cannot wait to discover more about Okinawa and Japan.

Steffen Michael Recktenwald
I earned my Ph.D. in Chemical and Process Engineering from the Karlsruhe Institute of Technology in Germany under the supervision of Prof. Norbert Willenbacher. During my doctoral studies, I focused on researching polymeric and wormlike micellar solutions, specifically their behavior in strong elongational flow fields. Following my Ph.D., I worked as a postdoctoral researcher with Prof. Christian Wagner at Saarland University. Together, we investigated in vitro blood flow dynamics, employing microfluidic techniques to study red blood cells' behavior in narrow capillaries under different flow conditions. In February 2024, I joined OIST as a staff scientist in the Micro/Bio/Nanofluidics unit, where my research primarily focuses on developing experimental techniques for understanding complex fluids and flows. In particular, we want to understand how viscoelastic polymeric liquids behave in time-dependent extensional flow fields. I am grateful to be a part of the unit and OIST. Outside of work, I'm excited to explore the beauty of Okinawa, its culture, and its cuisine.
