About

Dr Jesús Javier Ojeda is an Associate Professor in the Department of Engineering. His main research focuses on biofouling and biocorrosion, and the importance of cell/surface composition and environmental conditions (such as pH, nutrients or ionic strength) on biofilm formation. His research includes the use of modern potentiometric and spectroscopic tools (such as ToF-SIMS, micro-FTIR, XPS, EXAFS) to describe these systems.

Dr Ojeda’s expertise also includes the behaviour of micro/nanoparticles in complex media, as well as the adhesion of microorganisms to the particle surfaces. Recently-awarded NERC funds allowed him to develop a proof-of-concept for the rapid identification, sizing and quantification of microplastics in the wastewater treatment process (NE/K007521). This research pioneered in the use of novel spectroscopic methodologies for the monitoring of these emerging pollutants in an automated way, without bias and with minimal human intervention.

Dr Ojeda has secured funds both as a Principal Investigator and Co-Investigator from several funding bodies, including NERC, EPSRC, InnovateUK, The Royal Society and The Leverhulme Trust. He has also acted as an expert adviser at ETCBrunel, with more than 100 consultancy works carried to the private sector in surface characterisation, biocorrosion, plastic degradation and materials failure. Before coming to the UK, Dr Ojeda worked in catalysis, surface characterisation and quality control for the oil industry.

Dr Ojeda is a member of the Physical Chemical and Biochemical Methods committee (EH/003/02) at the British Standard Institution (BSI), and UK-nominated expert to the International Organization for Standardisation (ISO) for the standard regarding the analysis of microplastics using vibrational spectroscopy.

Taught Modules

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.
