Uchafbwyntiau Gyrfa
Ymchwil
Prif Wobrau
Dynameg Amgylcheddol
Mae ein hymchwil yn canolbwyntio ar amrywioldeb amgylcheddol yn ystod y cyfnod Cwaternaidd ac effeithiau newidiadau yn yr hinsawdd yn y dyfodol. Ffocws ein hymchwil yw’r rhanbarthau hynny sy’n arbennig o sensitif i newidiadau yn yr hinsawdd (gan gynnwys hinsoddau trofannol ac oer a’r rheiny sy’n dioddef o danau gwyllt). Mae hefyd yn ystyried y rhyngweithio rhwng newidiadau yn yr hinsawdd, ymyrraeth ddynol a digwyddiadau trychinebus.
