Future directions Continue existing research collaborations Bioinformatics – HIV data, Gene identification Software Engineering – Analysis of code Optimisation – adaptive parameters, representations Recently secured funding from Zeis Meditech in conjunction with Moorfield’s to generate substantial data on visual fields and retinal images EPSRC first grant Optimisation with adaptive parameters BBSRC new investigation scheme Combining databases (GO ENSEMBL) into coherent models of the human genome EPSRC advanced fellowship?

Summary Record of working within Brunel over 4 years Multiple projects and collaborations with a number of institutions Good publication record including several “grade A” journals Keen to build upon my research record
