About

Dr Daniel R Obaid qualified in medicine from the University of Cambridge in 2001 and completed specialist training in cardiology at the Wales Deanery. He was a British Heart Foundation Clinical Training Research Fellow at the Royal Papworth Hospital and the University of Cambridge (2009-2012) where he completed a PhD using invasive and non-invasive imaging to identify vulnerable atherosclerotic plaque, work that led to the award of the Young Investigator Prize at the Society of Cardiovascular CT, USA.

Currently he is a clinical academic working as an honorary consultant interventional cardiologist at the Morriston Regional Cardiac Centre and a clinical associate professor based at the clinical imaging facility in the ILS 2.

Taught Modules

PM-241F Doctor as a Professional 1

This module provides medical students with an introduction to professionalism - an approach that is essential for good medical practice. Based on the professional values and behaviours domain of the GMC¿s Outcomes for Graduates (2020), and in particular, professional values, fitness to practise, professional regulation, medical errors and reflection on/in practice, this module enables students to develop and manifest their professionalism within both an academic and a clinical context.
PM-266 The Cardiovascular System

Leading on from the first year Human Physiology Module (PM-154), the Cardiovascular Module will introduce and define the fundamental cellular mechanisms that regulate the physiology of healthy cardiovascular function. The Module will describe the processes that allow regular heartbeat and blood vessel function and how perturbations in the systems covered may lead to pathophysiological conditions. There will be an emphasis on experimental approaches used to study the cardiovascular mechanisms described.
PM-266C Y System Gardiofasgwlaidd

Gan adeiladu ar fodiwl Ffisioleg Ddynol y flwyddyn gyntaf (PM-154), bydd y Modiwl Cardiofasgwlaidd yn cyflwyno ac yn diffinio'r mecanweithiau cellol sylfaenol sy'n rheoleiddio ffisioleg gweithrediad cardiofasgiwlaidd iach. Bydd y modiwl yn disgrifio'r prosesau sy'n galluogi gweithrediad iach curiad y galon a'r pibellau gwaed a sut gall aflonyddiadau yn y systemau a drafodir arwain at gyflyrau pathoffisiolegol. Bydd pwyslais ar ddulliau arbrofol a ddefnyddir i astudio'r mecanweithiau cardiofasgwlaidd a ddisgrifir.
PM-344 Capstone Project

The aim of this module is to provide a capstone experience to students¿ learning, through participating in their own enquiry-based research project, with guidance from an academic supervisor. The project may be laboratory or non-laboratory based, but it will always involve a research question that is drawn from the literature, and focused on a topic relevant to the life sciences. It will ask a research question and involve the critical analysis of research findings. Students will refine their oral and written communication skills to a graduate level through an oral presentation and dissertation on their research findings and conclusions.
PMW241F Meddyg fel Gweithiwr Proffesiynol 1

Mae'r modiwl hwn yn rhoi cyflwyniad i broffesiynoldeb i fyfyrwyr meddygol - ymagwedd sy'n hanfodol ar gyfer ymarfer meddygol da. Yn seiliedig ar barth gwerthoedd ac ymddygiadau proffesiynol Deilliannau i Raddedigion y Cyngor Meddygol Cyffredinol (2020), ac yn benodol, werthoedd proffesiynol, addasrwydd i ymarfer, rheoleiddio proffesiynol, gwallau meddygol a myfyrio ar/wrth ymarfer, mae'r modiwl hwn yn galluogi myfyrwyr i feithrin a dangos eu proffesiynoldeb mewn cyd-destun academaidd a chlinigol. Hyd at 100% `Cymraeg¿ ar gael, yn seiliedig ar y lleoliadau
