She received her PhD degree in 2000 on the "Evolution of Structural Hierarchy in Uniaxially Deformed Polylactic Acid Films as Followed by Spectral Birefringence Technique and Others" under the supervision of Dr. Miko Cakmak and Dr. Erhan Piskin from the Polymer Engineering Department, University of Akron, USA.
She joined the Clean Technology Research Group as postdoctoral research assistant, working on the optimisation of processing conditions for instrument development and preparation methods of biomaterials in scCO2. Gulay left the group in 2001, moving to the Institute of Polymer Engineering, University of Akron, Ohio, USA.
Dr Paul Christian
Paul was the first PhD student in the Howdle group (1996-1999). Having obtained a BSc at Nottingham, his PhD focused upon dispersion polymerisation in scCO2.
He then moved on to work as an RCUK Research Fellow at The University of Manchester.
Dr Steve O'Connor
Dr Steve O'Connor was the first postdoc in the group. He came to Nottingham from the group of Prof Harry Allcock (Pennsylvania State University (1993-1996)) and brought expertise in polymer synthesis.
Steve left in 1997 to work with Cambridge Display Technology Ltd.
Additional former group members include:
