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.

After completing my PhD in Biophysics (von Heijne Lab, Stockholm University) I moved to OIST and the SCB unit in Oct 2014. During my graduate studies I focused on the bacterial cell division and membrane protein topology using super resolution- and time resolved fluorescence microscopy.

Here at OIST I have switched gears and I am currently working on determining protein structures in native bacterial cell membranes mainly using cryo-electron tomography (cryo-ET). I’m also keen on exploring the relative new ground of cryo super-resolution fluorescence microscopy in combination with cryo-ET in a correlative approach.

Living on a Tropical Island means a lot of time hanging on the beach or snorkeling in beautiful waters, quite the change from cold Sweden. Loving it.  

Lately I have also taken up on my old hobby in playing soccer, with our very own OIST FC.

  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. I am grateful to be here. 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.
