Short bio: I am an associate professor in operational research at the School of Mathematical Sciences within the University of Southampton where I am affiliated to the OR Group and CORMSIS. Prior to joining the University of Southampton, I was a Research Fellow at the University of Birmingham and had previously worked as a Research Associate at the Technical University of Freiberg. I am a Fellow of the Alan Turing Institute for Data Science and Artificial Intelligence, a Fellow of the Institute of Mathematics & Its Applications, and a Fellow of the Higher Eduction Academy.

13 October 2021: I was giving an online talk today at the LANS Seminar, ran by the Argonne Laboratory for Applied Mathematics, Numerical Software, and Statistics. Thank you to Jan Hückelheim and Vishwas Rao for organizing the seminar, as well as to all the participants, especially to Sven Leyffer for the very interesting discussion that followed. 04 October 2021: Welcome to Dr Lateef Jolaoso and David Benfield, joining my team from today, as Postdoc and PhD student, respectively. Lateef will be working on the EPSRC project on approximations of two-level optimal value functions, while David will be developing numerical methods for Stackelberg adversarial learning problems. 16 September 2021: Congratulations to my MSc students Tianjie Gu and Hanyu Wang, as well my Intern Adithya Madhusoodanan for their first conference presentation at OR63. All their presentations were around applying machine learning to address various issues around the COVID-19 pandemic. See copies of their posters here: Tianjie, Hanyu , and Adithya. 10 August 2021: My paper Semismooth Newton-type method for bilevel optimization: Global convergence and extensive numerical experiments (with Andreas Fischer and Shenglong Zhou) accepted for publication by Optimization Methods and Software 03 August 2021: My paper Deep learning methods for screening patients' S-ICD implantation eligibility (with AJ Dunn, MH ElRefai, PR Roberts, S Coniglio, and BM Wiles) accepted for publication by Artificial Intelligence in Medicine 01 July 2021: My interview with The OR Society's Inside OR Magazine - It can be freely accessed here.
