I was very pleased to have the opportunity to talk at the CBBG forum in Leicester at the Institute of Structural and Chemical Biology, very well co-organised by former Oxford colleague Richard Hopkinson. I spoke about our work on cyclic peptides binding to PHD2, as published in Chemical Science, and some more recent follow-up work. This was a great meeting; an excellent day of Chemical Biology talks and posters, as well as a chance to network, catching up with some people I already knew and making some new contacts.
