I am a postdoc at the University of Southampton working with Dr Manda Banerji. We are developing a package obs_vista to process VISTA data using the LSST stack. Our aim is to build joint HSC-VISTA and eventually LSST-VISTA catalogues. Our research is targeted to galaxy evolution and high redshift astronomy. However, we aim to build a general framework for multiwavelength optical to near infrared science with Rubin Observatory data.
