Tolun, Gökhan

Overview

After receiving my Ph.D. and completing my postdoctoral training in the USA, I have joined UOW in December 2017 as an electron microscopy specialist, including cryo-EM.

Research Overview

Main main area of interest is studying bio-nano-machines carrying out processes involving nucleic acids, such as DNA recombination, replication, repair, and RNA transcription.

My multi-disciplinary research group utilizes
- Molecular imaging (Electron microscopy)
- Structural biology (cryo-EM)
- Biochemistry
- Molecular Biology
In addition to the state-of-the-art cryo-EM, we also use the classical EM techniques such as shadow-casting (i.e., metal shadowing) and negative staining.
