  • PhD in Applied Mathematics, University of Cambridge, 2008.
  • DEA (Masters) in Theoretical Physics, Université Paris VI, 2002.
  • BA (Hons) in Mathematics, University of Cambridge, 2000.


Alexandra Tzella studied at the University of Cambridge, where she obtained a Bachelor's degree in Mathematics and at the Ecole Normale Supérieure (ENS) in Paris where she obtained a Master’s degree in Theoretical Physics.  In 2003, she returned to the University of Cambridge to complete a PhD at the Department of Applied Mathematics and Theoretical Physics. She was then awarded Marie-Curie and ENS fellowships to undertake research at the Laboratoire de Météorologie Dynamique. In 2011, she became an EPSRC post-doctoral research assistant at the University of Edinburgh before moving to the University of Birmingham in 2013.
