Dr. Tijna Alekseeva
Imaging Core Facility (ICF) provides access and training to the imaging instruments in the GSH, currently including a small animal 7T MRI (Bruker), spinning disc confocal microscope (CQ1, Yokogawa), confocal microscope (SP5, Leica), fluorescent/light microscopes (AxioImager, Zeiss) as well as image processing stations (CQ1 off-line image analysis and CellPathFinder).
Responsible for the training, coordination and maintenance is Dr. Tijna Alekseeva. She serves as single point of contact for all questions related to the imaging equipment as well as advice on the experimental set up, development of new analytical pipelines and general enquiries related to imaging. At the MRI, Dr. Alekseeva is supported by Marco Lollies who is taking care of routine measurements for internal and external users.
All imaging instruments are primarily available to the research groups of the Georg-Speyer-Haus. However, external research groups can apply at any time.
Dr. Alekseeva received her PhD in tissue engineering from University College London (United Kingdom) and worked as a postdoctoral fellow in the group of Prof. Dr. Dr. James Kirkpatrick at Mainz University Hospital and under the supervision of Prof. Fergal O’Brien at RCSI University of Medicine and Health Sciences in Dublin (Ireland). Dr. Alekseeva joined the GSH in 2017 as lab manager in the group of Dr. Sevenich. Since October 2021 Dr. Alekseeva acts as Head of the ICF.
