Trosolwyg
Mae gen i dros ugain mlynedd o brofiad ymarferol ac ymchwil mewn ffotograffiaeth fforensig a meddygol. Yn yr Ysgol Deintyddiaeth rwy'n darparu cefnogaeth ar gyfer ffotograffiaeth ddeintyddol a llif gwaith digidol.
Mae fy niddordebau ymchwil yn cynnwys, dulliau delweddu amgen, megis Ultraviolet, is-goch, traws-polareiddio a delweddu 3D mewn ffotograffiaeth fforensig. Mae fy ngwaith mewn delweddu 3D a dulliau delwedd eraill wedi canolbwyntio ar ymchwilio i fethodolegau i leihau gwallau mewn dadansoddiad fforensig o anafiadau corfforol, fel cleisiau.
Rwyf wedi cynhyrchu canllawiau ffotograffig cenedlaethol ar agweddau ar ffotograffiaeth fforensig a meddygol. Cyflwynwyd mewn confrences a rhoddwyd gweithdai iddynt mewn llawer o gynadleddau cenedlaethol a rhyngwladol. Rwyf wedi cyhoeddi penodau mewn gwerslyfrau a gydnabyddir yn rhyngwladol ar ffotograffiaeth fforensig a meddygol.
