Personal profile


Kirstine Berg-Sørensen is associate professor in biological physics. Her erliest research experience dealt with quantum mechanical and semi-classical models of laser cooled atoms and the physics of such laser cooled atoms while she in 1999 changed direction to biological physics. This change was kick-started by a 6Mkr grant from the Danish Research Agencies to initiate the first optical tweezers activity in Denmark, at the Niels Bohr Institute, University of Copenhagen. Within biological physics, she has in particular been interested in analysis and models of data from single molecule experiments, both in in vitro and in vivo systems, with main emphasis on experiments conducted using optical tweezers, optical traps in microfluidic systems and also micro-particle-velocimetry measurements. The latter in connection with osmotic flows in plants, or flow near structured surfaces.

Most recently, she is actively involved in experimental work to couple biophysics and optical trapping in biological systems with quantum sensing by means of color centers in diamonds.

Apart from her research activities, she has at DTU served as Head of Studies for the MSc education in Physics and Nanotechnology.
