I am currently a postdoc at the University of Sheffield, UK, with Tom Bridgeland. I completed my PhD studies at the University of Pavia, Italy, under the supervision of Jacopo Stoppa.
Research interests
Geometric structures arising from enumerative data and wallcrossing phenomena. Bridgeland stability conditions, Frobenius like structures and connections with integrable systems, representation of quivers, mathematical physics.
