Mae Dr Jesús Javier Ojeda yn Athro Cyswllt yn y Coleg Peirianneg. Mae ei brif ymchwil yn canolbwyntio ar fiofaeddu a biogyrydiad, a phwysigrwydd cyfansoddiad celloedd/arwyneb ac amodau amgylcheddol (fel pH, maetholion neu gryfder ïonig) ar ffurfiant bioffilmiau. Mae ei ymchwil yn cynnwys defnyddio offer potensiometrig a sbectrosgopig modern (fel ToF-SIMS, micro-FTIR, XPS, EXAFS) i ddisgrifio'r systemau hyn.

Hefyd, mae arbenigedd Dr Ojeda yn cynnwys ymddygiad micro/nanoronynnau mewn cyfryngau cymhleth, yn ogystal ag adlyniad micro-organebau i arwynebau’r gronynnau. Diolch i gyllid NERC a ddyfarnwyd iddo’n ddiweddar mae wedi datblygu prawf o gysyniad ar gyfer adnabod, mesur a meintioli microplastigau yn gyflym yn y broses trin gwastraff dŵr (HEFIN/K007521). Arloesodd yr ymchwil hon y defnydd o fethodolegau sbectrosgopig newydd ar gyfer monitro'r llygryddion hyn sy'n datblygu mewn ffordd awtomataidd, heb ragfarn a heb fawr o ymyrraeth ddynol.

Mae Dr Ojeda wedi sicrhau cyllid fel Prif Ymchwilydd a Chyd-Ymchwilydd gan sawl corff ariannu, gan gynnwys NERC, EPSRC, InnovateUK, Y Gymdeithas Frenhinol ac Ymddiriedolaeth Leverhulme. Mae hefyd wedi gweithredu fel cynghorydd arbenigol yn ETCBrunel, gyda mwy na 100 enghraifft o waith ymgynghori ar gyfer y sector preifat mewn nodweddion arwynebau, biogyrydiad, diraddio plastigau a methiant deunyddiau. Cyn dod i'r DU, bu Dr Ojeda yn gweithio mewn catalyddu, nodweddiadu arwynebau a rheoli ansawdd ar gyfer y diwydiant olew.

Mae Dr Ojeda yn aelod o'r pwyllgor Dulliau Cemegol a Biocemegol Ffisegol (EH/003/02) yn y Sefydliad Safon Prydeinig (BSI), ac arbenigwr a enwebwyd y DU i'r Sefydliad Safoni Rhyngwladol (ISO) ar gyfer y safon o ran dadansoddi microblastigau gan ddefnyddio sbectrosgopi dirgrynol.

Oes gennych chi ddiddordeb mewn gwneud PhD?

Os oes gennych frwdfrydedd a diddordeb mawr mewn ymchwil PhD ar ryngweithio bacteria/arwynebau, cymhlethiaethau metel bacterol, catalysis, neu wyddoniaeth arwyneb gyda chymwysiadau mewn peirianneg biocemegol, cysylltwch â mi.

EG-203 Biochemical Engineering I

To provide an understanding of Biochemical Engineering as a sustainable activity concerned with the safe economic processing of biological materials and feedstocks, to make products for a healthy and prosperous quality of life. Topics will cover biochemical reaction kinetics, fundamentals of enzymatic and microbial processes, reactor design principles for enzyme and fermentation systems, recovery and purification of products, sterilisation techniques.
EG-M11 Biochemical Engineering II

This module builds up from EG-203 (Biochemical Engineering I) and describes more advanced topics in the production and optimisation of biological materials and processes. Optimisation methods of bioprocesses are described, and how these are exploited in the commercial situation. Topics such as mixed cultures, allosteric enzymes, genetically modified micro-organisms, biofouling and biocorrosion, specialised biological separation processes (e.g. chromatography), biosafety, quality control, and Hazard Analysis and Critical Control Points (HACCP) are discussed in detail. The principal products of such processes are investigated to illustrate the current and future technology of these systems with an emphasis on modern biotechnology methods. The impact of the use of such techniques on quality management, safety assessment and regulatory environment are reviewed.
EGC401 Industrial Engineering and Research Practice

This module aims to give students practical experience in either the industrial setting or the research environment.. Either two day placements in industry or two day research placements within the School are conducted. The industrial placements are determined by interview with the companies involved or departmental staff. A range of research projects will be offered by the staff.
EGCM89 Chemical and Environmental Engineering MEng Design Project

This module aims to advance and broaden the design practices learnt at Level 3. This project will necessitate the students to adapt the design methodologies learnt previously to an unfamiliar molecule in order to generate a novel manufacturing process. The project itself requires the students to develop an innovative design for a plant to make a molecule for which no large scale production facility exists. The molecules to be produced need to be selected on the following characteristics: they should not be manufactured on a large capacity production facility (there may however be small scale production) and an outline of a manufacturing process including basic chemistry exists somewhere. The project will require the students to make choices and judgments on: the production capacity, time of operation, raw materials to use, production process, and benefit of the molecule to the company (ie economic, extending the knowledge base etc). Design is a team exercise throughout and working well as a team is critical to successfully completing this project.
