I am an active member of a number of large collaborations/consortia organised around massive stellar research. I work on projects analysing spectra within the VFTS and BLoEM collaborations which are each based on ESO large surveys obtaining multi-epoch optical spectra of large samples of OB-type stars in the LMC and SMC to understand binary statistics of massive star populations. I am leading projects within the XShootU collaboration oriented around spectroscopic analysis of the HST DDT ULLYSES programme and its community-led optical follow-up survey on ESO VLT X-Shooter which is primarily designed to understand the impact of metallicity on stellar winds. I am developing the massive star science cases and technology requirements for upcoming space telescopes UVEX and HWO. Which will obtain unprecedented surveys of massive stars at low metallicity, from an order of magnitude large samples of UV spectroscopy in the LMC and SMC with UVEX to resolving individual stars at 10Mpc in the lowest metallicity local environments known with HWO. I am also collaborating on extreme populations of massive stars at high redshift observed through gravitational lensing with JWST as part of the Cosmic Spring team.
