Søren Vrønning Hoffmann

 

My role in InterCat is to aid and design experimental instrumentation at the ASTRID2 beam lines for the center, especially with focus on VUV-UV photo-absorption and irradiation of simulated interstellar ices.  

I am a Senior Scientist at ISA, Centre for Storage Ring Facilities, a part of the Department of Physics and Astronomy at Aarhus University, where I am the head of beamlines for our synchrotron radiation source ASTRID2.

I finalized my Ph.D. in surface science in 1996, before moving on to being responsible for beam lines and optical development at ISA. I have more than 20 years of experience in synchrotron radiation optics and instrumentation, and collaborate with many other beam line scientists in optical/instrumental development around Europe and worldwide. My main research focus shifted from surface science in the early 2000s, to photo-absorption of gasses and further on to circular dichroism spectroscopy (CD) on biomolecules.

My research

 

Currently, my main interests lie in spectroscopy on bio-molecules, such as amino acids, proteins and RNA/DNA in solution, solid and gas form. Through international collaborations, I currently work and research within topics such as homochirality of life, photo-absorption in simulated comet and planet ices, RNA/DNA electronic-structure influence on radiation protection, UV-absorption in greenhouse gasses and a dash of protein properties, for example, protein and peptide stabilization of emulsions, and time resolved protein folding.

My role in InterCat is to aid and design experimental instrumentation at the ASTRID2 beam lines for the center, especially with focus on VUV-UV photo-absorption and irradiation of simulated interstellar ices.
