Biography

Rile Ristic is currently a Reader in Crystal Science and Engineering at the University of Sheffield, Sheffield, UK. He received his Ph.D in Physics at Belgrade University. He began his academic career as a Research Fellow at the Institute of Physics at Belgrade University. In 1989, he moved to Strathclyde University, Glasgow, where he worked as a Senior Research Fellow in two research areas: (i) crystal growth and characterisation of large single crystals for non-linear optical devices, and (ii) growth and characterisation of small crystals (< 1 mm), an area which covers a wide range of industrially important materials concerning speciality chemicals and pharmaceuticals. He joined the Department of Chemical & Process Engineering at the University of Sheffield as a Lecturer in September 1998, rising through the ranks to become Reader in 2005. Prior to this, in 2001/2002, Dr Ristic spent some time at Hiroshima University, Japan, as a Visiting Professor. In 2002 he was elected as a Fellow of the Institute of Physics (FInstP) for “his very high level of achievement in physics and outstanding contribution to the profession”.

Dr Ristic's primary area of research is solid state physical chemistry, which he has used to create many of the basic techniques for understanding fundamentals of crystallisation processes and their application to industrial practice.
