Dimitris was awarded a Bsc in Applied Mathematics and Physics from the National University of Technology in Athens (Greece) before completing his Msc in Applied Mathematical Sciences with Biological and Ecological Modelling at Heriot-Watt University in Edinburgh, Scotland. During his studies, he learned a broad range of topics in the areas of mathematical modelling, mathematical ecology, mathematical biology and medicine, dynamical systems, applied linear algebra, numerical analysis, regression analysis, linear models and designs, computer science along with their applications in physics and engineering.

In late 2012 Dimitris joined the University of Dundee and The James Hutton Institute to undertake a PhD in mathematical modelling of plant root systems funded by the European project EURoot (

Research Interests

My interest in mathematical modelling of branching structures of biophysical systems and their interactions with the environment stems largely from my research during my postgraduate studies in mathematical neuroscience and my work on models of molecular movement in neurons.

PhD Studentship

The project involves the development and application of novel mathematical and computational methods in modelling of plant root systems. Innovative mathematical techniques in numerical simulation, model parameterisation and model sensitivity analysis were used to calibrate the root growth density-based model on various genotypes in a range of reference environmental conditions. Results from this work aim to uncover key biological factors and plant traits that can be targeted by breeding.

Key research points: PDE modelling, numerical analysis, optimisation, application of PDEs to image analysis, image analysis pipelines, computer programming, plant image analysis software.

Supervisors: Dr Lionel Dupuy (James Hutton Institute), Dr Glyn Bengough (James Hutton Institute / University of Dundee and Dr Mariya Ptashnyk (University of Dundee)

I was responsible for the supervision of undergraduate students doing course projects at University of Dundee and Duncan of Jordanstone College of Art and Design. I mentored final year undergraduate Engineering students and regularly assisted the preparation and delivery of undergraduate Mathematics lectures, tutorials and computer lab workshops and workshops on “Mathematics modules and different approaches to teaching mathematics at school” for undergraduate students studying for education degrees.

I am also really interested in different approaches to teaching Mathematics. Being a teaching assistant, STEM ambassador, volunteer, fundraiser and participant in public engagement events and activities events speaking about science and interdisciplinary research in Mathematics to students and to the public performing interactive events led to my personal projects:

  • Rootie, the Robin Root on the m-aRt-hS Planet
  • Be a Scientist or Sci-artist
  • LEMMAs: Language - Etymology - Mathematics Meanderings through Art and Science
