Pynciau Arbenigol: Micro weithgynhyrchu, peiriannu rhyddhau micro drydanol, prosesu polymer, integreiddio graddfa hyd, gweithgynhyrchu main, dylunio prosesau, actifadu arwynebau, bioddynwared.

Mae fy mhrif ffocws ymchwil ym maes Technoleg Micro a Nano (MNT).

Ffocws fy astudiaethau PhD yn y Ganolfan Peirianneg Gweithgynhyrchu, Prifysgol Caerdydd oedd Micro Weithgynhyrchu. Yn benodol, peiriannu rhyddhau micro drydanol i'w gymhwyso wrth gynhyrchu offer mowld micro-chwistrellu a gweithgynhyrchu micro gydrannau.

Rwyf wedi ymgymryd ag ymchwil MNT o dan raglenni ariannu FP6, FP7, EPSRC, TSB, WEFO ac A4B yr UE. Mae fy ngweithgaredd ymchwil wedi'i gyplysu ag 8 mlynedd o brofiad diwydiannol yn y sectorau modurol a dyfeisiau meddygol a diagnostig.

O ganlyniad, mae gennyf gefndir technegol ac ymarferol cryf o fewn meysydd dylunio/gweithgynhyrchu offer mowldio chwistrellu, actifadu arwynebau a gweithgynhyrchu main.

Yn ogystal, rwy'n Beiriannydd Siartredig (FIMechE) ac yn Uwch Gymrawd yr Academi Addysg Uwch.

EG-3080 Engineering Management (Aero, EEE, Mech)

The goal of this course is to provide the skills for professional engineers to meet the challenges of their future careers, whether they be in academia, industry, or as an entrepreneur. Irrespective of future careers engineers will be involved in projects, management and business organisations and an awareness of these issues is important for all team members. It should be recognized that the topics included in the course are not limited to scientists and engineers, they are useful for people in any careers. This course is not aimed at making you a certified project manager, but to provide the skills that will allow you to be a more effective project team member and also when you start to take on the role of project manager. With respect to business management aspects, the course will cover the basic concept of entrepreneurship before breaking down the essential elements of a business plan. The course will give the more entrepreneurial students guidance about how to go about commercialising their ideas and the less entrepreneurial students an understanding of what makes some of their colleagues tick. The learn by example approach adopted for this module guides the student through the complexities of financial and human resource management and encourages students to develop their own business plans. Students will also be introduced to the subject area of ethics, liability and responsibilities within business. This module will also provide support on careers services with students creating CVs and Linked-In accounts.
EG-365 Manufacturing Optimisation

The module provides an introduction to the philosophy and tools used within the Lean Six Sigma methodology. The module will provide an overview of the Toyota Production System (TPS) and the quality systems applicable within manufacturing.
EG-M106 Polymer Processing

The module will provide a deeper understanding of the technology of plastics processing. The material covered will cross cut the engineering disciplines of advanced manufacturing technology and polymer science to broaden the technical and industrial context of polymer processing. Within the content of the module simulation software will be applied to industrial case study examples for critical evaluation. In addition, the application of polymer replication technologies within the emerging field of micro manufacturing will be presented, focusing on the advantage and limitations of size effect and length scale integration. The module will include practical demonstration laboratories and also include industrial visits.
