Dr. Stoyan Yordanov has more than 15+ years of experience in the area of Applied Physics. He is a physicist who specialized in the area of Optical Microscopy and Spectroscopy – building sophisticated optical setups and using them for scientific studies.
After obtaining his bachelor and master degree in physics Stoyan moved to Mainz, Germany for his PhD (2007). In there he joined the group (“Physics of Interfaces”) of Prof. Hans-Jürgen Butt at Max Planck Institute for Polymer Research (Mainz, Germany) where he performed micro- and nano-fluidic studies – studying the so called boundary slip phenomenon on hydrophilic and hydrophobic surfaces with the help of optical microscopy. In particular, under the supervision of Dr. Kaloian Koynov, he learnt about and entered in the filed of FCS (Fluorescence Correlation Spectroscopy) and LSM (Laser Scanning Microscopy) as well as he built and used the so called TIR-FCCS (Total Internal Reflection Fluorescence Cross Correlation Spectroscopy) technique to investigate the so called slip velocity or slip length on hydrophilic and hydrophobic surfaces (fundamental hydrodynamic studies).
After obtaining his PhD he did few postdocs in Belgium, Germany and Italy. He obtained further knowledge and experience in variety of Optical Microscopy and Spectroscopy techniques as well as variety of fields – chemistry, biology, material science, microfluidics, plasmonics, sensing, nanofabrication, lithography etc.
Among the notable techniques he got vast experience with are the following ones:
- Fluorescence Correlation Spectroscopy (FCS)
- Optical Super-resolution STED (Stimulated Emission Depletion) Microscopy
- Light Sheet Fluorescence Microscopy (LSFM)
- Laser Speckle Contrast Imaging (LSCI)
- SERS (Surface Enhanced Raman Scattering) and Raman Spectroscopy.
Since 01 October 2023 he joined the Neurotechnology group of Asoc. Prof. Dimiter Prodanov at IICT-BAS (Institute of Information and Communication Technology – Bulgarian Academy of Sciences) to work on the VIBraTE project. He will be building the optical microscopy setup to measure experimentally biomechanical effects of viscoelastic coupling between brain implants (electrodes) and brain tissue (emulated by phantom medium).
