Lars-Göran Öfverstedt, Staff Scientist

As you might recognize from my name, I’m from Sweden. I got my PhD in Biochemistry in 1983, but I soon thereafter got more interested in structural biology, especially electron tomography. I started to collaborate with Ulf Skoglund and joined his group at Karolinska Institutet, Stockholm, Sweden, in 1992.  We started to implement new software to improve reconstructed 3D maps. The successful application of these computer programs is well documented in a number of publications and the development of the software in terms of stability, accuracy and speed has continued throughout the years .

At present, my focus is, besides electron microscopy, implementation of new algorithms for 3D map improvements.

  Gunnar Wilken, Staff Scientist

I am German and joined the Structural Cellular Biology Unit in 2011.
I received my Diplom, PhD, and Habilitation in mathematics from the University of Münster, Germany. My background is mathematical logic, in particular proof theory. Before coming to OIST I was postdoctoral fellow at the Ohio State University, USA, invited researcher at Ghent University, Belgium, and researcher at the University of Münster. Here at OIST I became also interested in mathematical biology and inverse problems, in particular electron tomography.

rina  Endang Rinawati Purba, Research Unit Technician

I’m from Jawa-Indonesia. I obtained my PhD in Biomedical Chemistry (2015) at Kwansei Gakuin University of Japan. I joined OIST as a Postdoc from 2015. During that time, my focus is in membrane protein structural study of receptors protein. Now, I moved to Structural Cell Biology Unit and started to learn something totally different: Cryo-electron Tomography. My concentration for now is helping my team to visualize individual molecules, whether in tissue or purified protein to describe the dynamics of the different molecules and to support the software development projects that will enable for higher resolution. I'm also interested in membrane trafficking protein in nervous system. I believe that impossible is nothing!


hong  Hong Huat Hoh, Junior Research Fellow

Born and raised in Malaysia, I pursued medical study in Poland after high school and before moving to Okinawa to transition into research. I have recently graduated with a PhD (August 2020) in the field of molecular oncology. I am currently exploring and further expanding my interest in the world of biological molecules by studying membrane proteins using structure prediction tools as well as molecular electron tomography.


  Qingyuan Tian, Specialist

I am from China where I received both my undergraduate degree in Automation Control and my Master E. in Computer Science and Technology in Tsinghua University. In March, 2015, I joined this research unit as a programmer, to add new functions and upgrade our in house molecular electron tomography (MET) software. Before this work, I had mainly three kinds of work experience: 1, An IT specialist in the Tax Bureau in my hometown in Hubei province, China; 2, A language information processing researcher in Beijing Language and Culture University (including one year’s visiting research in the University of Tokyo); 3,  A software architect in a software development company in Japan.  Now I am enjoying the challenging and interesting work here in OIST. My hobbies are cooking, hiking, and Tai-Chi.


  Shizuka Kuda, Research Administrator

I am originally from Okinawa, but studied in Kumamoto and USA for long time.

Received BA in Business Administration from WSU-Cougars, worked as Procurement Specialist in USNH and Account Reps at Insurance Company in USA.

I’ve been with Structural Cellular Biology Unit since the Unit started in 2010 and really glad to be assisting Unit Members.
