Joana Costeira-Paulo initially joined as a visiting scientist from the University of Uppsala in Sweden in 2020 and was then a postdoc after completing her PhD in October in 2021. Joana has been investigating how experimental conditions in native MS might affect the state of proteins and protein complexes. This is central for how transferable MS results are to the native cellular environment of the proteins under study. She was also developing of a new computational tool to calculate  collision cross-section (CCS) that is both accurate and fast and to convert this research-grade algorithm and code into software that can be released and commercialised. The fast high-accuracy calculation CCS compared with that of experimental CCS will enable unambiguous identification and characterisation of molecules. In her spare time, Joana is an enthusiastic watercolour artist.
