Stefan Roesner

Assistant Professor

Portrait of Stefan RoesnerStefan Roesner received his Diploma in chemistry from Philipps-University Marburg, Germany in 2010. He moved to the UK and completed a Ph.D. in organic chemistry with Prof. Varinder Aggarwal at the University of Bristol in 2014. After postdoctoral studies at the Massachusetts Institute of Technology under the supervision of Prof. Stephen Buchwald, he returned in 2016 to the UK to become Senior Research Fellow in the Shipman group. In October 2021 he was promoted to become Assistant Professor.

Groups at Warwick


  • 2010, Dipl. Chem. from Philipps-University Marburg, Germany
  • 2014, PhD from University of Bristol, UK
  • 2015-2016, Postdoctoral Research Associate, Massachusetts Institute of Technology, USA
  • 2016-2021, Senior Research Fellow, University of Warwick, UK
  • since 2021, Assistant Professor, University of Warwick, UK

I am working on the following projects at the moment:

  • Functionalisation of cyclic hydrazines
  • Synthesis of carbolines and related heterocycles

I am currently interested in the following areas:

  • Continuous-flow synthesis
  • Metal-catalysed cross-coupling reactions
  • Synthesis of functionalised heterocycles

I am module lader for CH161 Introduction to Organic Chemistry, and teach the third part of this course

Get in touch if you consider applying for PhD studies. The University of Warwick offers several schemes to fund home and international students.
