I am excited to meet a large number of amazing scientists, talk science and present our latest work.

I will also use the trip to cross one item of my bucket list by watching a Michigan Football game at The Big House.

Very excited to be traveling back to the USA for the first time since the end of my postdoc with Ben Cravatt in 2017. It is going to be a big one with 2 conferences, 4 department visits and 6 talks over the next two weeks. Looking forward to a great (and probably also exhausting) trip. (1/5)

New paper by the group of Lyn Jones. They study the amino acid reactivity and plasma stability of sulfonyl imidazole (SuDEx) and triazole (SuTEx) electrophiles showing enhanced stability and tyrosine reactivity for SuDEx.

Are PROTACs that engage target proteins in an irreversibly covalent manner viable?

A new Nature Communications paper by the groups of Jin Wang and Xiaoli Qi now convincingly shows potent BTK degradation employing an irreversible BTK ligand.

A true firework of covalent drug discovery to close out the Covalent Modulation in Drug Discovery Conference #CovModDrugDiscov!

Ed Tate presented a variety of exciting projects of his group.

Interesting talk by Michael Bodnarchuk from @astra-zeneca.bsky.social at #CovModDrugDiscov.

He talked about the use of computational tools to discover covalent, brain-penetrant KRAS G12C inhibitors.

Exciting talk by Yoav Shamir from the group of Nir London at #CovModDrugDisvov!

He talked about cofolding in Alphafold3 to identify #CovalentInhibitors with novel structures for BTK.

Interesting talk by Chloe Oxford from GSK at #CovModDrugDiscov.

She talked about a MALDI-TOF-MS-based assay to characterize the binding of #CovalentInhibitors to challenging proteins with resolution of the binding site.
