I am a PhD candidate in Economics funded by the Economic and Social Research Council.

My full CV and ongoing research can be found in my personal website

My PhD project is in collaboration with the Office of Manpower Economics who provides an independent secretariat to the Pay Review Bodies of the British public sector. As such, my thesis is concerned with the gender pay gap among public sector doctors with a focus on changes over time and over the lifecycle. In specific, the thesis investigates how the gender pay gap changes over time and how these changes compare to other highly skilled and paid occupations. In light of a complex pay structure, I also investigate how gender gaps in doctors' pay progression evolve over the lifecycle and the influences of employment transitions on these differences.

My supervisory team are Professor Melanie Jones and Dr Ezgi Kaya.



Work in progress:

  • Trends of the gender pay gap among public sector doctors in the UK
  • The gender pay gap in occupations of the UK public cector
  • Gender differences in wage growth along a doctor's career


Research interests:

  • Applied microeconomics
  • Labour economics
  • Gender economics
  • Microeconometrics


  • Job mobility and maternity.
  • Wage variation across the public and private sector, across firms and within-occupations.
  • Pay centralisation.
  • Gender differences in labour supply.
  • Programme evaluation.
