Dr Jesús Ojeda

Jesús Javier Ojeda graduated from the Department of Chemistry, Simon Bolivar University, Venezuela, where he gained a degree in Chemistry in 2000. Since 1998, he has been participating in research activities and then working full-time on surface characterisation, catalysis and analytical chemistry in the oil industry. In 2003, he became an Associate Specialist in Analytical Chemistry at Chemiconsult C.A. and in January 2004, he moved to the University of Sheffield in order to study sorption of organic pollutants in soils.

In April 2005 he was appointed as a Research Associate in Spectroscopy at the Laboratories of Environmental Sciences, Kroto Research Institute, The University of Sheffield, and later was made responsible for the Institute’s Surface Analysis Centre (XPS and ToF-SIMS).

In February 2010, he was appointed as a Lecturer in Surface Analysis at ETCbrunel.

Dr Ojeda’s PhD work was a study the nature of interactions between biological materials and surfaces using potentiometric and spectroscopic techniques (such as imaging-FTIR, ATR-FTIR, XPS, EXAFS, and potentiometric titrations).  This work is reflected in his current research interests, which also include:

· Detection, quantification and monitoring of the interactions between cells, colloids and engineered nanomaterials in complex environmental media.

· Sorption and complexation of radionuclides by bacterial cell walls, and their potential application for the treatment of nuclear waste.

· Design and characterisation of coatings for the inhibition of bacterial growth, and biocompatible coatings for medical applications.
