Mae iâ mewn natur yn hardd, yn gyffredin, yn ddiddorol, yn newid yn barhaus ac yn fregus. Mae'n llifo, yn torri ac yn ymddwyn mewn ffordd sy'n adlewyrchu ei strwythur crisialaidd, a'i gyfaint mawr. Rwy'n bodloni fy niddordeb mewn rhewlifoedd a llenni iâ drwy eu monitro o'r gofod, gan ddefnyddio systemau delweddu lloeren i astudio sut maen nhw'n ymddwyn a sut maen nhw'n ymateb i newid yn yr hinsawdd.
Rwy'n arbenigo mewn defnyddio radar agorfa synthetig (SAR) sy'n defnyddio ynni microdon i gaffael delweddau waeth beth fo'r gorchudd cwmwl a'r noson begynol - gallu sy'n arbennig o werthfawr yn yr Arctig a'r Antarctig. Fy arbenigedd yw defnyddio delweddau sydd wedi'u caffael yn rheolaidd i gofnodi cyfraddau llif wyneb a newid deinamig.
Mae fy ngwaith wedi cwmpasu'r Himalayas, Yr Ynys Las, Svalbard ac Antarctica, ac rydw i wedi bod yn ddigon ffodus i wneud gwaith maes yn yr holl ranbarthau hyn.
Mae fy ngwaith diweddar wedi canolbwyntio ar sefydlogrwydd sgafelli iâ – estyniadau arnawf rhewlifoedd sydd ar gyrion y rhan fwyaf o Antarctica, ac ymraniad mynyddoedd iâ – y broses sy'n rhyddhau a cholli rhew i'r cefnfor. Mae digwyddiadau ymrannu'n amrywio o ddarnau bach yn disgyn o rewlifoedd i achosion enfawr, fel ffurfio Mynydd Iâ A-68 yn 2017, sy’n chwarter maint Cymru.

GEC276 Systemau Gwybodaeth Ddaearyddol
A Geographic Information System (GIS) is a computer-based technology for solving problems of a geographical nature ¿ i.e. involving spatial relationships between people, places and objects. It can be applied to a wide range of disciplines within geography and has developed to provide a means to quickly and professionally produce maps from geospatial data. This module provides a basic grounding in GIS from the nature of spatial information, through the use of GIS in social and physical geography contexts, to the application of computers to solving complex geographical problems. Most importantly, it allows hands-on experience in using Quantum GIS (QGIS), the leading open-source GIS software package, and therefore provides a valuable skill for research and the for workplace.

GEG331 Dissertation Report: Geography
The dissertation is an original, substantive and independent research project in an aspect of Geography. The dissertation research project is based on 20 - 25 days of primary research (e.g fieldwork, lab work, archive work) and several months of analysis and write-up. The end result must be less than 10,000 words of text. The dissertation offers you the chance to follow your personal interests and to demonstrate your capabilities as a Geographer. During the course of your dissertation, you will be supported by a peer-led discussion group and a staff supervisor. Lectures and guidance are delivered via this module and peer and staff led Dissertation Support Groups are delivered via GEG332. Participating in Dissertation Support Groups is vital, and is assessed and, in these groups, students will provide constructive criticism to fellow students undertaking related research projects, learning from their research problems and subsequent solutions. This support and supervision is delivered through GEG332, which is a co- requisite.

GEG332 Dissertation Support: Geography
This module provides structured, student-led peer-group support and academic staff group supervision for students undertaking the 30-credit 'Dissertation Report: Geography' module. This support and supervision is assessed through the submission of the Dissertation Outline and the Dissertation Support Group Reflection and Attendance Log. Working within a supervised Student Peer Group, students have the opportunity to provide constructive criticism to fellow students undertaking related research projects, learning from their research problems and subsequent solutions. Group sessions are the main support provision as student¿s work through their Dissertation. This module complements the 'Dissertation Report: Geography' module, which is a co-requisite.

GEG344 The Cryosphere in a Changing Climate
This module will provide you with the scientific basis to understand the physical behaviour of glacier ice in our changing climate. We will look at spatial scales ranging from individual ice crystals to continental-scale glaciation. The module core topics will include glacier mass balance, transformation of snow to ice, glacier hydrology, glacier dynamics, ice crystal structure and deformation, glacier sliding, deformation of glacial sediments, glacier flow instabilities and glacier surging. We will introduce example topics of current research interest. The module is assessed through examination, as well as group presentation on a seminar and a short individual report.

GEGM22 Geographical Information Systems
Delivery of teaching will be live. Assessment will be self-directed activities and an online test. This module is available to all postgraduate students within the Faculty of science and engineering, Medicine and Human and Health Sciences. Student should be familiar with basic computing and will benefit from numeracy skills.
