Dr Khaled H Assi obtained his BSc in the Sciences of Chemistry in 1994 and was awarded the PhD in pharmaceutical analysis by the University of Bradford, in 1999.

He then took up a post doctoral post at university of Bradford between 1999-2001 working on the inhaled therapies.  His post doctoral program was extended for one more year through an awarded grant from Glaxo SmithKline joint with Professor H Chrystyn .

In 2002, he was accepted a research fellowship at Bradford School of Pharmacy. Dr Assi was appointed as a Lecturer at the Bradford School of Pharmacy, in July 2004 and has continued developing his research in the inhaled therapies area. In this position he is teaching the pharmacy and pharmaceutical management students at different levels.  The modules he delivers cover the area of pharmaceutical analysis, Quality assurance and quality control of pharmaceuticals.

He is also active in the research. His research interests cover the inhalation therapies and developing of pharmaceutical and bioanalytical assay methods for the determination of inhaled drugs in biological fluids to measure the lung deposition.

He has published over 35 Conference and Journal papers. He supervised 4completed PhD projects and currently supervising 2 PhD students. He was an internal examiner for many PhD theses and also he is a reviewer for several international journals
