Menelaos has been working as a Lecturer in Medical Statistics at the Department of Statistical Science, UCL since April 2019. He also has the role of the Mentor for Postgraduate Teaching Assistants. He collaborates with the National Institute of Cardiovascular Outcomes Research (NICOR) at Barts Health NHS Trust, where he is part-based, and provides statistical oversight of the analytical team. Menelaos completed a degree of Mathematics in 2004 at the Aristotel's University of Thessaloniki, Greece, followed by an MSc in Statistics (2005) in the Department of Statistical Science, UCL.
After having worked for a consulting company, he pursuit 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. He was awarded with a PhD in 2012, and until 2016 was employed as a post-doctoral research associate in the Department of Statistical Science, UCL.
