Biography

Klaus Suhling develops and uses advanced multidimensional fluorescence imaging techniques such as Fluorescence Lifetime Imaging (FLIM) to understand the properties and interactions of macromolecules in the life sciences. After obtaining his PhD in the field of fluorescence spectroscopy from the University of Strathclyde, he held several post-doctoral positions in biology, chemistry and physics departments, mostly at Imperial College London, working on fluorescence microscopy and the development of photon counting techniques. Professor Suhling joined King’s College London in 2003 and was a Lecturer and a Reader before being promoted to Professor of Physics in 2014.

Research

Fluorescence Lifetime Imaging, time-correlated single photon counting, photon counting imaging, time-resolved fluorescence.

Current research: Diffusion studies of labelled drugs and proteins, cells using FRAP and tr-FAIM, FLIM and FAIM of fluorescent molecular rotors, imaging of nanoparticles in cells, photon counting imaging with an image intensifier or an electron-bombarded CCD.

Self-funded PhD students

A limited number of PhD projects is offered on the understanding that a successful applicant will secure funding to cover tuition fees and living costs from external sources by himself. Prospective applicants should contact the project supervisor listed below prior to making application. The applications should be made on-line via https://myapplication.kcl.ac.uk/ quoting the name of the prospective supervisor.

Development of photon counting imaging techniques for time-resolved fluorescence microscopy

The aim of the project is to adapt photon counting imaging for Fluorescence Lifetime Imaging (FLIM) microscopy. The technological challenge is develop FLIM systems that combine a high detection sensitivity with a large spatial and temporal resolution and with a minimum of acquisition time. This project at the physics/life-sciences interface will use a novel photon counting imaging technique to address this issue. The project will provide training in a variety of fields: fast cameras and imaging techniques, image analysis, software development, fluorescence spectroscopy, optical imaging and microscopy applied to cell biology. For further details contact Dr Klaus Suhling

Fluorescence lifetime and polarization-resolved imaging of fluorescent molecular rotors

Fluorescence imaging techniques are powerful tools in the life sciences, because they are non-destructive, minimally invasive and can be applied to living cells and tissues. Fluorescence can be characterised by position, intensity, lifetime, spectrum and polarization. The project will use Fluorescence Lifetime Imaging (FLIM) and polarization-resolved imaging of fluorescent molecular rotors – these are special dyes whose fluorescence lifetime and brightness depend on the viscosity of their environment. We will use this practical and versatile approach to map the viscosity in cells and other specimen.For further details contact Dr Klaus Suhling.

Polarization-resolved fluorescence imaging of GFP-tagged proteins in living cells to study protein clustering

The project will involve setting up an inverted fluorescence microscope with a polarization-resolved imager which splits the image into two - one with vertical and the other with horizontal polarization. The set-up will be tested before it is applied to biological samples. The next step is to perform polarization-resolved imaging of GFP-tagged proteins in cells. We will study ErbB homodimers and heterodimers – the biologically important ErbB2/ErbB3 heterodimer has been purported to be a potent mitogenic and oncogenic unit for a variety of cancers including breast tumours. The multidisciplinary project will provide training in a variety of fields: fluorescence spectroscopy, optical imaging and microscopy applied to cell biology, and basic cell biology. For further details contact Dr Klaus Suhling.
