Biography
I am a Senior Lecturer and ARC DECRA Fellow at the School of Mathematics and Statistics, University of Melbourne. I am also an Associate Investigator for OPTIMA.
My research interests are broadly in nonlinear optimization, data science, and numerical analysis, with applications to areas such as imaging and climate science. I have particular interests in derivative-free optimization and bilevel optimization.
Details of my CV, publications, talks and software are available on this website (or look at Google Scholar and Github). For general optimization resources, see my nonlinear optimization resources page.
