ITAMP fellow at the Harvard-Smithsonian Center for Astrophysics and Harvard Physics Department Since September 2007 I have been working towards a PhD in the group of Professor Bretislav Friedrich at the Fritz Haber Institute of the Max Planck Society in Berlin. Our work was mainly concerned with a theoretical treatment of molecules in electric, magnetic and radiative fields, including field-dressed molecular collisions. In April 2011 I defended my PhD thesis, and stayed as a postdoctoral fellow with Prof. Friedrich until September. Since September 2011 I'm appointed as an ITAMP fellow at the Harvard Smithsonian Center for Astrophysics.
If you are interested it details, please have a look at the summary of research projects I've been working on until now: [pdf] My Curriculum Vitae: [pdf]
