The Willitsch Group - Cold and Controlled Molecules and Ions
Welcome to the Cold and Controlled Molecules and Ions group at the University of Basel led by Prof. Stefan Willitsch and the astrochemistry subgroup led by Dr. Jutta Toscano. Our research is concerned with the preparation and control of cold molecules and molecular ions and their applications in both chemistry and physics. On this website, you can find information about our group, our research, our teaching and opportunities to join us.
Recent news
Mudit receives the Faculty Prize for the best PhD thesis from our university’s president Prof. Andrea Schenker-Wicki.
A warm welcome to our new PhD student Mikhail Popov. He obtained his master degree from Lomonosov Moscow State University, Moscow. He will work on the CryoQute experiment.
