Mae fy mhrif ddiddordeb ymchwil mewn cemeg arwynebau, deunyddiau, polymerau, a choloidau a hefyd o ran datblygu a deall y gydberthynas rhwng y strwythurau a fabwysiadwyd gan wlychwyr/ gwlychwyr polymerig ar ryngwynebau a phriodweddau ffisegol y deunyddiau hyn mewn toddiannau. Bydd gan ddeunyddiau o'r fath ystod eang o ddefnyddiau ac fe'u defnyddir yn helaeth, o adferiad olew uwch (EOR) a fformwleiddiadau gofal personol i gyfryngau trosglwyddo cyffuriau.

Mae fy ngwaith presennol yn y Sefydliad Ymchwil Diogelwch Ynni (ESRI) yn canolbwyntio'n bennaf ar gemeg materol, ymarferoliad/synthesis nanoronynnau a microronynnau.

EG-101 Chemical Engineering Laboratory

This module provides practical experience of conducting bench-scale experimental studies on a variety of systems (comprised of both apparatus and contents) in order to observe, record and characterise the behaviour of these systems under specified conditions. Students are typically required to determine factors which may influence a system¿s overall response, for example, experimental results can be linked with theory (from lecture-based modules or equivalently from directed reading) to determine physical or thermochemical properties of materials, or, to evaluate how such properties influence the performance of the system. Wider analysis aims to link and develop skills in data acquisition and processing, error analysis, and interpretation of experimental results. As a component part of these studies, students will build experience of conducting experiments in a laboratory environment, documenting results, organisation and communication of experimental results and analysis through both tabular and graphical formats accompanied by written discussion; this being evidenced first through maintenance of their own laboratory notebooks and secondly through technical report writing exercises.
EGCM01 MSc Research Practice

A Masters level course to deliver knowledge and skills on how to write and submit scientific papers and reports. The course requires that the students prepare multiple reports focused on specific aspects involved in preparing a draft publication of journal quality. Research data is gathered and, subject to suitable data analysis, is used to write a draft publication. In addition to this, a graphical abstract for a highly cited paper in a relevant chosen field needs to be prepared, as does a letter to an editor. For the paper writing, data is gathered from laboratory-based work and the students must analyse the data and write up the results as a suitable manuscript. They must make a reasoned choice of journal; then follow the format required by that specified journal and its instructions. They must present results appropriately and of the correct quality and then describe and discuss these. The students must also prepare a substantial literature survey (up to 5000 words) on a topic in chemical or biochemical engineering. The course is designed as such so there are multiple smaller assignments prior to the substantial literature review so students can learn and improve through the duration of the course.

EGCM30 MSc Dissertation - Chemical Engineering

The EGCM30 research project is the major item of directed independent learning undertaken during the master¿s programme and will normally be carried out on a research topic proposed by a member of staff from the Faculty of Science & Engineering. Study for the dissertation, which may be based on practical, industrial, simulation or literature work, or any combination of these, is carried out over a period of about 12 weeks, with the dissertation submitted at the end of September.
EGDM01 Colloid and Interface Science

Students will gain an in-depth understanding of the properties of colloids and their importance in industry.
