The Sigel lab focuses on the principles of metal ion-assisted folding and the structure of functional RNAs. | This group account is managed by students |
Zurich, ZH - Switzerland
Joined April 2021
There's a joint spotlight collection on Bioinorganic Chemistry between Chemical Science and Dalton Transactions - and our paper on elucidating the structure of G4 quadruplexes ( https://t.co/x3AIBjZC7D) has been selected! Check out the collection here:

Do you want to assign solution structures of G-quadruplexes using NMR? Maybe this new approach we just published works for you. Congrats to Zhenghui and Carla for this amazing work! https://t.co/auUCkDFe7n

Roland and our PostDoc @LindlarNiko visited the EuroBIC17 in Münster last week. While Roland presented our work on the recently discovered theta ribozymes, Niko spoke about one of his projects from his Ph.D. in the @DaumannL Lab.

We scientists have a responsibility to act against climate change. Part of that is advising and educating the public and part of it is keeping our own house in order. So, we applied and got the bronze LEAF - Laboratory Efficiency Assessment Framework - medal!

We congratulate Federico Held for completing his master thesis with us. Federico introduced a heteroatom into RNA and used this to look at the BCL-2 RNA G-quadruplex. Thanks for the great time Fede!

Last friday the Sigel group traveled to Bern. Why? To learn about RNA research in Switzerland at the Swiss RNA Workshop. Besim Fazliji, a Ph.D. candidate in our group, gave a talk about " Dissecting the exon binding mechanism in group II intron splicing" - and it was great!

Two weeks ago our Ph.D. students joined the CMSZH graduate school retreat - together with all other Ph.D. students from @UZH_Chemistry! It was a great time to enjoy Swiss mountains and learn about the fascinating research done at our own Department!
