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

Bywgraffiad
Derbyniodd Dr Şengül Tezel ei B.Sc. a graddau MS yn 2005 a 2006, yn y drefn honno, gan yr Adran Mathemateg ym Mhrifysgol Bilkent, Twrci. Cwblhaodd ei D.Phil. mewn Mathemateg yn y Sefydliad Mathemategol ym Mhrifysgol Rhydychen, y DU. Gweithiodd fel ymchwilydd ôl-ddoethurol rhwng 2010 a 2011 ym Mhrifysgol Coimbra, Portiwgal. Ar ôl gweithio yn Adran y Gwyddorau Naturiol a Mathemategol ym Mhrifysgol Özyeğin, Twrci, a'r Gyfadran Peirianneg a Gwyddorau Naturiol ym Mhrifysgol Sabancı, Twrci, ymunodd â Phrifysgol Caerdydd, Ysgol Mathemateg ym mis Hydref 2021.
