Yn wreiddiol o Lundain, mae Chris wedi bod ym Mangor ers 2002, pan ddaeth o i astudio seicoleg fel myfyriwr is-raddedig. Mae o wedi bod yn aelod gyfadran ers 2015 ac mae'n gweithio yn bennaf ar y Raglen Seicoleg Glinigol fel Tiwtor Ymchwil. Mae ei ymchwil yn edrych ar sut y gall ffactorau cymdeithasol yn siapio ein hiechyd corfforol a meddyliol. Mae gynno fo ddddordeb arbennig y modd y mae etifeddiaeth Cymru o gloddio am lo yn parhau i ddylanwadu ar iechyd.

Dyma fideo byr a wnaeth yr Academi Prydeinig am un o'm mhrosiectau ymchwil, a ariannwyd ganddynt: https://www.youtube.com/watch?v=bl8NhyS0tjg (yn Saesneg)

• PhD: Individual differences in reaction time variability: A combined psychometric and electroencephalographic approach
  2011

Mi wna i gyfiethu fy nysgu mor fuan a phosib!

Mae gen i ddiddordeb mewn sut mae ein hunaniaethau a lle dan ni'n byw yn rhyngweithio i siapio ein iechyd corfforol a meddwl. yn benodol, dwi wedi bod yn gweithio ar y pynciau canlynol:

1. Sut mae bod mewn lleiafrif ar gyfer rhan pwysig o'ch hunaniaith yn effeithio'ch iechyd meddwl?
2. Sut mae gwaddol diwydiant glo Cymru parhau i effeithio ein iechyd?
3. Pa ffactorau cymdeithasol sy'n gysylltiol â penderfyniadau dynion i ddefnyddio steroidau anabolig?

Yn bennaf, ymchwilydd meintiol ydw i, yn defynddio cymysg o ddata arolwg, gwyliadwraeth iechyd, adaeryddol; ond dw i'n mwynhau cydweithio gydag ymchwilwyr ansoddol ar brosiectau ymchwil dull cymysg.

epidemioleg gymdeithasol iechyd meddwl ac ymddygiadau iechyd, yn enwedig anghydraddoldebau daeryddol mwen iechyd meddwl, y perthynas rhwng hunaniaeth ac iechyd, a mesur yr effaith iechyd meddwl o ddigwyddiadau gwleidyddol cymdeithasol.

• BU-IIA Funded Project: Covid-19’s transition to endemicity in Wales and Kentucky

  As we move towards the endemic phase of Covid-19, personal protective behaviours are becoming optional guidance, rather than mandated rules. In this new environment, understanding people’s behaviour and how they conceptualise the balance of personal and social rewards and risks, is an important priority for public health. We aim to help shape public health initiatives through two surveys, enriched with qualitative interviews, examining people’s attitudes and behaviour in Wales and Kentucky. Like Wales, Kentucky has a large declining coalfield region, which has faced significant public health challenges before and during the Covid-19 pandemic. The project aims to identify the sociodemographic and attitudinal factors associated with how people are reacting to Covid’s transition to endemicity in the two countries.

  The project will aim to deepen our collaboration with partners in Public Health Wales and in Kentucky, while also building towards a strong REF impact case study and further grant capture. Two related outcomes are (1) to understand what factors support collective population behaviours, such as those seen during Covid-19, and might also be required for future challenges such as the climate crisis or in responding to world conflict. And subsequently, (2) a more systematic understanding of how to communicate risk to different societal groups and hence how to promote healthy behaviours (including Covid-19 PPBs) across Wales.
