Benjamin Heidt
I completed my Ph.D. in Biosensing under the supervision of Dr. Bart van Grinsven and Prof. Thomas Cleij at Maastricht University in January 2022. My work focuses on 3D printing and biosensing with/of/around microorganisms. In my research regarding 3D printing, I specialized in creating microstructures and microfluidic channels via SLA and mSLA 3D printers, as well as creating a novel method coined Topographical Vacuum Sealing, which combines 3D printing and vacuum forming to decrease the channel size of 3D-printed microfluidic structures. My research regarding biosensing revolves around Point-of-Care diagnostics, especially their use for resource limited settings. Here I use several detection techniques from optical and electrochemical readout methods to more niche applications such as detection via thermal resistance. I joined the Micro/Bio/Nanofluidics unit as a postdoc in April 2022 to continue my research on microfluidic biosensor integration. Next to this I am the founder of Flui.Go Science, a startup that produces microfluidic building blocks to teach the next generation about science.

Igors Dubanevics

I was born and raised in Latvia, and I have spent most of my life in a small city by the Baltic Sea. After finishing high school, I flew to York (UK) to study Natural Sciences for four years. While I initially wanted to be a chemist, I eventually specialized in Physics due to its versatility and dynamic faculty. During my time at York, I worked on protein dynamics induced by thermal fluctuations, which explored the transfer of information in noisy environments. This research was entirely computational, drawing ideas from Statistical Physics.
Since then, I have undergone a slight change in direction and scale at OIST. My research question now focuses on the evolution of bacterial cells in confined geometries. This project is a continuation of a collaboration between BCU and MNBU at OIST and involves both theoretical and experimental work.
Outside of work, I find refuge in books, particularly Russian classics, and music (Bach and John Coltrane are among my favorite artists). Since arriving in Okinawa, I have enjoyed exploring the island on foot, by bike, and with swimfins, and I plan to continue doing so.
