Trosolwyg
Rwy'n gydymaith ymchwil, yn gweithio ar Cosmoleg gyda'r Athro Erminia Calabrese ers mis Hydref 2020. Cyn hyn, cefais fy ngraddau Baglor a Meistr ym Mhrifysgol Leiden, gan raddio gyda fy nhraethawd Meistr ar ddisgrifiad Theori Maes Effeithiol o Chwyddiant Aml-Maes. Fe wnes i fy PhD yma yng Nghaerdydd, gan weithio ar ddadansoddiad Bayesian o setiau data CMB.
O fewn fy ymchwil, rwy'n gweithio gydag arsylwadau o'r CMB gan y Telesgop Cosmoleg Atacama (ACT) a chydweithrediad Arsyllfa Simons (SO). O fewn y cydweithrediadau hyn, rwy'n gweithio ar y biblinell ar gyfer echdynnu blaendir ac amcangyfrif paramedr cosmolegol.
Yn ddiweddar, rwyf wedi ysgrifennu tebygolrwydd WMAP a thebygolrwydd Planck ar gyfer arbrofion cyfunol (h.y. ACT + WMAP, ACT + Planck, ac ati). Rwyf wedi gwneud cyfraniadau mawr i bapurau ACT Data Release 6 (DR6), gan berfformio profion null, dadansoddi data, a dewis modelau cosmolegol.
Ar wahân i gosmoleg, mae gen i ddiddordeb bob amser mewn siarad am ieithyddiaeth, lle mae fy mhrif ddiddordeb yn ieithoedd y Dwyrain Agos yn ystod y cyfnod cyn-Glasurol (yn benodol mae Old-Persian, Ugaritic a Sumerian yn ffocws fy astudiaethau cyfredol).

Ymchwil
I am very much interested in Cosmology, both from a theoretical and observational aspect.
I am currently working within the Simons Observatory (SO) collaboration and on the observations of the CMB by the Atacama Cosmology Telescope (ACT).
