Senior Lecturer in Chemical Engineering

Background:

Gül heldseveral positions at BHR Group (1995-2015) prior to becoming a Senior Technical Consultant. During her time at BHR Group, Gul set up and\or managed and worked on several R&D and consultancy projects, including large, multi-partner projects, such as the Fluid Mixing Processes (FMP) Consortium (40+ industrial member companies, an annual budget of over £600K), Dispersion of Micro and Nanoparticles in Liquids (DOMINO) consortium (7 industrial members, annual budget of £120K), PROFORM (EC project nb. 505654; 3.5 M euros budget): Transforming nano-particles into consumer care products through advanced product and process formulation; AddNano (EC Contract nb 229284; 12 M euros budget): Scale up and formulation of new lubricants with improved tribological properties. She has extensively lectured in the field of mixing and dispersion processes, during the annually held Improved Mixing Processes (1996 onwards) and Dispersion of Nanomaterials in Liquids (2008 onwards) courses or courses held at clients’ site. She co-supervised PhD students during her time at BHR Group.

Prior to BHR Group she worked as a Senior Research Fellow (1993-95) at the University of Birmingham School of Chemical Engineer on a project titled Development of an improved impeller design (sponsored by SERC, DTI and APV Baker Ltd.). She co-supervised undergraduate and MSc students for their design and research projects. Gül also worked as a Research Associate at the University of Cambridge Department of Chemical Engineering (1992) on oscillatory flow reactors.
