Biography

I obtained an M.Sc. degree in Mathematics from the University Pierre and Marie Curie (Paris VI, France) in 2011. I completed my Ph.D. in the field of optimisation in the University of Paris-Est (France) in 2015, and I has been a Research Associate in Heriot Watt University from 2015 to 2018, in the EPS school. I am now an Assistant Professor in both EPS and MACS schools.
