My research developments aim to contribute to the field of quantile-based methods in modelling and estimation. These new methods, have applications in fields such as economics and the health sciences, and also address significant issues related to the wider scientific research community. I have recently completed my PhD in Statistics with several first-author publications in this field of Robust Statistics.
