Professor Gero Steinberg

Director of the Bioimaging Unit, Professor of Cell Biology

Since 2007 I am Professor of Cell Biology in Exeter and director of the Bioimaging Centre in the School of Biosciences. Nowadays, I am most interested in how dynamic processes support the function of cells. We are using live cell imaging of proteins and organelles in fungal cells to answer fundamental cell biological questions, but also address fungicide mode of action and the molecular basis of invasive growth in fungal plant infection. Our cell biology research helps to understand fungal pathogenicity, but also reveals evolutionary conserved mechanisms of spatial organisation in eukaryotic cells.

Dr Christian Hacker

Facility Manager - Experimental Officer for Electron Microscopy

After obtaining a diploma in biology at the University of Wuerzburg, Germany, I began my PhD in the lab of Prof. Marie-Christine Dabauvalle, focussing on the formation of nuclear pore complexes after mitosis. In 2010 I started a postdoctoral position at the University of Dundee in the lab of Dr John Lucocq working on the function and biogenesis of microsporidian mitosomes. That position involved the application of various electron microscopic techniques and quantitation methods which I was trained on continuously during my research. In 2012 I followed Dr Lucocq to the University of St Andrews where I continued to work on the cell biology of microsporidia as well as being involved in the establishment of a biological transmission electron microscope. During that period I participated in numerous collaborations with various groups in St Andrews as well as UK-wide projects involving quantitative electron microscopy. Since 2013 I have been a teacher at the EMBO practical course for advanced electron microscopy for cell biology.

In March 2015 I started my position as an experimental officer for electron microscopy in the Bioimaging Centre and shortly after took over the research facility managment.

Paulina Cherek

Senior Research Technician for Electron Microscopy

In 2012 I obtained a Master degree in Molecular Biology from the University of Gdansk, Poland. From 2016 I worked as a core facility technician for the Transmission Electron Microscopy Facility at Biomedical Center, University of Iceland, Iceland. I was responsible for fixation and processing of samples embedded in resin in room temperature as well as cryo conditions and immunolabeling. I also participated in two projects involving anticancer drug testing. In the Bioimaging Centre I will be mainly responsible for operating High Pressure Freezing and Freeze Substitution machines as a new methods of sample preparation for Electron Microscopy. I will also work as a support in sample preparation for TEM and SEM. In 2022 I was appointed to Senior Research Technician for Electron Microscopy for the Bioimaging Centre.


Dr Corin Liddle

Senior Research Technician for Light Microscopy

After obtaining a degree in Environmental Biology at Plymouth University, I worked as a research assistant within the Ecotoxicology Research & Innovation Centre (ERIC), Plymouth University, where I developed my use of widefield microscopy, while imaging zebrafish. Subsequently, I undertook my PhD research at Heriot Watt University, Edinburgh, where I studied the fate and toxicity of silver nanomaterials (AgNM). I then worked as a research fellow at Exeter University, where I investigated the interaction and transfer of nanoplastics within a simple food web. During this project I extensively applied fluorescence and confocal imaging, and image quantitation and processing techniques. Since February 2020 I have been supporting the light microscopy users, within the Bioimaging center. In 2022 I was appointed to Senior research technician of light microscopy for the Bioimaging Centre.

Yasaman Taheriabkenar

Research Technician for Light Microscopy

During my Master’s degree research project in stem cell-based models of human embryo in 2022, I developed knowledge and skills in fluorescence and confocal microscopy. After obtaining my Master’s degree, I started working in the Bioimaging Centre to support the new lightsheet microscopy system and other light microscopes (Confocal laser scanning systems, and wide field microscopes).

Verena Hacker

Research Finance Administrator

In 2020 I started working as a Finance Administrator for the Bioimaging Centre. My role is to take care of all financial aspects of the Centre including setting up new projects, invoicing microscope usage, budget control and general communication with regards to all financial enquiries.

Dr Martin Schuster

Research Fellow

I previously worked as an Experimental Officer at the Bioimaging Centre in Exeter to run the light microscopy part of the Centre. In spring 2016 I became Research Fellow in Prof. G. Steinberg's group. I still support the Bioimaging Centre in imaging applications.
