Biographical Details 
Photo of Menelaos Pavlou

I am a Lecturer in Medical Statistics at the Department of Statistical Science since April 2019. I am also leading a Mentoring and Support program for Postgraduate Teaching Assistants. I collaborate with the National Institute of Cardiovascular Outcomes Research (NICOR), where I am part-based, and I provide statistical oversight of the analytical team.

I completed a degree of Mathematics in 2004 at the Aristotle’s University of Thessaloniki, Greece, followed by an MSc in Statistics (2005) at the Department of Statistical Science, UCL. After having worked for a consulting company, I pursued a part-time PhD in Medical Statistics in the Department of Statistical Science, UCL (2007), while working as a Medical Statistician at the Centre of Sexual Health and HIV Research, UCL. I was awarded with a PhD in 2012, and until 2016 I was employed as a post-doctoral research associate in the Department of Statistical Science, UCL. 

Research Interests

I am interested and currently working on topics in the following areas:

  • Risk Prediction Modelling
  • Prediction-oriented variable selection in low-dimensional settings
  • Penalised Regression method (Ridge, Lasso etc.)
  • Comparison of Institutional Performance and Detection of Outliers
  • Analysis of Clustered Data and Informative cluster size
  • Missing data

I also have an interest in software development (e.g., see R package ‘sampsizeval’ for sample size calculations for validation of risk models).

Prospective PhD students

If you are interested to have a PhD related to the topics above, contact me at m.pavlou@ucl.ac.uk for an informal discussion. Keep an eye for departmental teaching assistantships and other funding opportunities here, and please get in touch well before the deadline to discuss/develop your research proposal.
