Bywgraffiad
Derbyniais y graddau B. Sc., M. Sc. a Ph.D. mewn Peirianneg Drydanol o Brifysgol Talaith São Paulo (UNESP), Campws Ilha Solteira, Brasil, yn 2012, 2014, a 2018 yn y drefn honno, gyda chymrodoriaethau a roddwyd gan São Paulo Research Foundation (FAPESP). Yn ystod y cyfnod hwn, cwblheais ddwy interniaeth ymchwil (yn 2014 a 2016) dan oruchwyliaeth yr Athro Dr. Behzad Kordi ym Mhrifysgol Manitoba (UofM, Canada) yn yr Adran Peirianneg Drydanol a Chyfrifiadurol gyda chymrodoriaethau a roddwyd gan y Rhaglen Dramor Interniaethau Ymchwil (BEPE/FAPESP). Gweithiais fel ymchwilydd ôl-ddoethurol a chydweithredwr ymchwil yn yr Ysgol Peirianneg Drydanol a Chyfrifiadurol (FEEC) - Prifysgol Campinas (Unicamp) yn y Labordy Foltedd Uchel o 2019-23 gyda chymrodoriaeth a roddwyd gan FAPESP. Ar hyn o bryd rwy'n gydymaith ymchwil yn y Labordy Foltedd Uchel. - Prifysgol Caerdydd-UK.
