Trosolwyg
Rwy'n aelod o'r Grŵp Ymchwil Mathemateg Gymhwysol a Chyfrifiadurol, y Tîm Ymchwil Mathemateg Arwahanol a Gwyddor Data, a'r Rhwydwaith Ymchwil Deunyddiau.
Rwy'n mwynhau llunio a datrys problemau mathemategol i ateb cwestiynau pwysig mewn gwyddoniaeth, peirianneg, a bywyd bob dydd. Mae hefyd yn rhoi pleser i mi ddarganfod dulliau mathemategol newydd a gofyn cwestiynau pellach ar hyd y ffordd. Llinell gyffrous iawn o fy ymholiad yw sut y gellir cyfieithu model neu dechneg fathemategol o un maes cymhwyso i'r llall. Mae'r mewnwelediadau rhyngddisgyblaethol y mae hyn yn dod â hyn bob amser yn ewarding iawn.
I ddysgu am ddatblygiad gwyddorau mathemategol ar gyfer darganfod, arloesi a'r economi, gweler Yr Ymgyrch dros Wyddorau Mathemategol (CaMS).

Ymchwil
Mae gen i ddiddordebau ymchwil eang mewn mathemateg gymhwysol a chyfrifiadurol yn y rhyngwyneb â'r gwyddorau ffisegol a naturiol. Mae fy arbenigedd mewn mecaneg solet sylfaenol a'r ddealltwriaeth fathemategol o ddeunyddiau meddal, gan gynnwys modelu aml-raddfa, dadansoddi cyflwr terfyn, optimeiddio, a meintioli ansicrwydd.
Arweiniais brosiectau ymchwil a ariennir yn allanol ar solidau cellog a systemau aml-gorff gyda chymwysiadau i feinweoedd biolegol a mater meddal, a gwnaeth gyfraniadau at elastigedd stocastig, sy'n faes sy'n datblygu'n gyflym ar flaen y gad o ran ymchwil rhyngddisgyblaethol mewn mecaneg continwwm. Fy monograff ymchwil, "Stochastic Elasticity: A Nondeterministic Approach to the Nonlinear Field Theory", Springer (2022) yw'r llyfr cyntaf i gyfuno elastigedd straen mawr sylfaenol a thebygolrwydd damcaniaid. Ei nod yw gwneud y ddwy ddamcaniaeth yn hygyrch i wyddonwyr sy'n dymuno ymgorffori meintioli ansicrwydd mewn astudiaethau ffenomenolegol o ddeunyddiau meddal. Mae'n llyfr modern sy'n ymdrin â phynciau ymchwil clasurol a mwy datblygedig.
Maes pwysig o fy ngwaith yw modelu mathemategol elastomerau crisial hylif (LCEs). Mae'r rhain yn ddeunyddiau amlswyddogaethol datblygedig sy'n cyfuno elastigedd â threfn gyfeiriadol. Yn benodol, mae straen mecanyddol yn arwain at newidiadau mewn trefn grisialog hylif ac mae newidiadau yn y drefn gyfeiriadedd yn cynhyrchu straen a straen mecanyddol. Oherwydd eu hymatebion materol cymhleth ym mhresenoldeb ysgogiadau naturiol fel gwres, golau, meysydd trydanol neu magnetig, mae LCEs yn addas ar gyfer ystod eang o gymwysiadau mewn gwyddoniaeth, gweithgynhyrchu ac ymchwil feddygol. Mae'r gwaith hwn yn darparu sylfaen ar gyfer modelu mathemategol pellach o hunan-drefnu mewn mater biolegol gweithredol.

Bywgraffiad
Trosolwg gyrfa
Dechreuais fy nhaith fathemategol fel myfyriwr israddedig ym Mhrifysgol Bucharest, Romania. Yn ddiweddarach fe wnes i barhau â'm hastudiaethau gyda Rhan III o'r Tripos Mathemategol ym Mhrifysgol Caergrawnt, y DU, a ariannwyd gan Ysgoloriaeth Canmlwyddiant Shell llawn a ddyfarnwyd gan Shell Group ac Ymddiriedolaeth Prifysgol Caergrawnt. Yn 2005, enillais fy PhD am ymchwil mewn dadansoddi rhifiadol o Brifysgol Durham, y DU. Yna ehangais fy arbenigedd fel ymchwilydd ôl-ddoethurol ym Mhrifysgolion Strathclyde, Caergrawnt, a Rhydychen, gan ganolbwyntio ar fathemategwyr a mecaneg solidau, lle roedd angen i fathemategwyr arbenigo yn y maes rhyngddisgyblaethol allweddol hwn. Ymunais â Phrifysgol Caerdydd fel Darlithydd yn 2011 a symud ymlaen yn raddol i'm rôl academaidd bresennol.
