Professor Roel Dullens

  • Professor and Tutorial Fellow in Chemistry

Profile

I obtained my MSc in Chemistry from the University of Utrecht in 2001. In 2005 I completed my PhD in Physical and Colloid Chemistry at the same university, under the supervision of Professor Willem Kegel. After that I joined the group of Professor Clemens Bechinger at the University of Stuttgart as an Alexander von Humboldt Research Fellow to work on optical tweezing in colloidal systems. In August 2007, I was appointed as a University Lecturer at the Physical and Theoretical Chemistry Laboratory at the University of Oxford, combined with a Tutorial Fellowship in Physical Chemistry at Lincoln College. In 2014, I became Associate Professor and, in 2016, I was promoted to my current position of Full Professor of Chemistry. I have been the recipient of an ERC Starting Grant in 2011 and an ERC Consolidator Grant in 2016, and I was awarded the 2019 Corday-Morgan Prize and the 2019 McBain Medal from the Royal Society of Chemistry.

College teaching

I teach Physical Chemistry to the Lincoln chemists in the first, second, and third your of the undergraduate course. I also lecture on various courses in the Department of Chemistry ('Liquids and Solutions' and ‘Introduction to the Liquid State’) and supervise fourth year MSc (Part II) projects. Finally, I am the advisor of several Lincoln graduate students.

Research

My research interests cover a wide range of topics in soft condensed matter, with an emphasis on colloidal systems. In particular, I combine the development of novel colloidal systems using synthetic colloid chemistry with state-of-the-art optical manipulation and imaging techniques to study fundamental problems in condensed matter science. My current research topics include the synthesis and characterisation of new colloidal model particles, two-dimensional colloidal systems, grain boundaries and other defects in colloidal crystals, manipulation of interfaces in colloidal systems, and driven colloidal systems.
