Biography
I am a Research Fellow employed in the TIDE ARC ITRH. I work as a statistician with focus on methodological developments in spectral analysis and uncertainty quantification, and applied research in the fields of oceanography and hydrodynamics. I also have experience in paleo-climate modelling, as well as offshore engineering disciplines. Please refer to my website for contact details; an up to date list of publications, presentations and code repositories; and some professional writings.
