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

Francesco Del Giudice
I received my PhD in Chemical Engineering at the University of Naples last April, under the supervision of Prof. Pier Luca Maffettone. During that period I was also a fellow at the Centre for Advanced Biomaterial for Healthcare  and visiting PhD student at University of Glasgow, working in strict contact with Dr. Manlio Tassieri. During this period I studied the effect of the fluid rheology on particle migration in square-shaped micro channels. In addition, during my period in Glasgow, I studied the use of optical tweezers in the microrheology of complex systems. Finally, we derived a novel method for measuring the fluid relaxation time through microfluidic flow. I joined this amazing group in December 2015 for my first Postdoc experience and I am currently working on the use of non-Newtonian fluids together with suspended cells for biomedical application. In addition, I am moving forward in the study of microfluidic techniques for deriving properties of complex fluids. Beside work, I like reading, travelling, meeting new people and sharing cultures. I like Salsa music and I am a piano player/composer.

Nikhil Bhalla
I completed my Ph.D. in Electronic and Electrical Engineering in 2015 under the supervision of  Dr. Pedro Estrela from the University of Bath in UK. Prior to Bath, I completed M.S. in Electronic Engineering from Chung Yuan Christian University, Taiwan in 2012 and received B.E. Honors in Electronics and Instrumentation from BITS-Pilani, India in 2010. Following Ph.D. I worked as a postdoctoral researcher at the University of Bath in UK for a period of 3 months just before joining here at Micro/Bio/Nanofluidics Unit. My research interest includes the development of sophisticated biosensing tools for the detection of post translational modification of proteins, disease detection, understanding various intra/inter cellular biochemical process on micro/nano devices. At OIST I will now work on engineering the microenvironment of cancer stem cells. Away from the lab, I ‘love’ cricket (unfortunately not much in Japan), outdoors, guitars and enjoy traveling. Okinawa is a beautiful island to work and live.

I completed my PhD at Osaka University under the supervision of Prof. Tadashi Inoue, primarily studying the effect of counter anion sizes on linear viscoelasticities for polymerized ionic liquids using rheo-optical techniques. During this period, I joined Prof. James Runt group at The Pennsylvania State University for 6 months as a visiting scholar and studied the use of dielectric relaxation spectroscopy in polyelectrolyte systems. I joined the Micro/Bio/Nanofluidics Unit as a postdoctoral scholar in April 2017. I am currently studying the flow behavior of non-Newtonian fluids around confined microfluidic cylinders as my first job at OIST. I am very glad to start my first Postdoc experience at this unit and I am looking forward to exploring the field of microfluidics. Beside work, I enjoy badminton, running, and getting abilities for fishing, Tamann (~30 cm) is one of seeking fishes at first. I also want to try sea activities during my stay in this tropical island.


Riccardo Funari
I completed my PhD in Industrial Engineering at the University of Naples “Federico II” in 2015 under the supervision of Prof. Raffaele Velotta, focusing on the design and realization of biomolecular quantification tools suitable for environmental control, food analysis and biomedical applications. More particularly, I worked on the detection of a wide range of analytes and harmful species including pesticides, mycotoxins, polycyclic aromatic hydrocarbons, proteins, biomarkers and bacteria. During this period, I had the chance to establish a fruitful scientific collaboration with Dr. Dirk Mayer group at Jülich Forschungszentrum in Germany concerning electrochemical biosensing and single protein imaging using atomic force microscopy (AFM). After receiving my PhD, I worked as postdoctoral researcher at the University of Naples for 2 years until I joined Micro/Bio/Nanofluidics Unit in July 2017. Here in OIST, I started working on the use of bacterial biofilm in optical biosensing and in the next future I wish to explore the advantages of coupling microfluidics and biosensing technology for realizing novel detection tools. Beside work, I love reading, snorkeling and learning more about this wonderful island.
