After his undergraduate studies at the University of Warwick, Prof. David Hilditch completed his PhD at the University of Southampton early in 2008. After postdoctoral work at the University of Jena, he won the FCT Investigator grant and moved to Lisbon, where he is now Assistant Professor at Instituto Superior Técnico. David also holds an adjunct Professor position at in Inter-University Centre for Astronomy and Astrophysics in India. David has published around 40 articles in high-impact journals, supervised 3 PhD thesis(es) and co-supervised 4 more, and supervised a number of MSc, with one ongoing at IST. He participates and/or participated as Principal investigator (or Co-PI) in 2 projects. David has given more than 60 invited talks at conferences, seminars and advanced international schools (too many to be practically listed individually). David works on the physics of gravitation, and in particular on strong-field gravity as described by general relativity. As a numerical relativist he is furthermore knowledgeable in the theory of partial differential equations, numerical analysis and high-performance computing, and related fields.
