Ymchwil
Mae fy ymchwil, yn y termau mwyaf cyffredinol, ar ddadansoddi hafaliadau differol rhannol aflinol a'i gymwysiadau mewn gwyddoniaeth a pheirianneg deunyddiau. Yn fwy penodol, mae gen i ddiddordeb mewn modelu ymateb materol o safbwynt clasurol yn ogystal â defnyddio'r theori cyfansoddiadol ymhlyg a ddatblygwyd yn ddiweddar. Mae gen i ddiddordeb hefyd mewn theori llif graddiant, systemau deinamig dimensiwn anfeidrol, a calcwlws amrywiadau.
