We are a young group funded by the European Research Council, based in the Centre for Theoretical, Atomic, Molecular and Optical Physics, School of Mathematics and Physics, Queen’s University Belfast. We are a family and diversity friendly group. Join us!


Group leader: Dr Dermot Green

Dermot is a Reader in Theoretical Physics (permanent faculty member) at Queen’s University Belfast, where he holds a European Research Council grant.

He has broad interests in theoretical and computational physics that include:
* Diagrammatic many-body theory
* Theory of positron and positronium interactions with matter
* Theory of atomic and molecular collisions
* Quantum chaos
* Ultra-intense laser plasma interactions/strong-field QED.

Research Fellows 

Dr Brian Cunningham,
(04/2019 —)

Brian graduated MSci and PhD from Queen’s University Belfast. He has expertise in computational condensed matter physics, notably incorporating vertex corrections in the Questaal code.

Dr Charlie Rawlins
(10/2019 —)

Charlie obtained a BSc in nanotechnology and his PhD in theoretical physics from Curtin University in Perth, Australia. His PhD in the theoretical physics group headed by Igor Bray, Alisher Kadyrov and Dmitri Fursa concerned positron and positronium scattering on atoms with a focus on anti-hydrogen formation. He has expertise in theoretical atomic physics and positronium.

Dr Andrew Swann

Andrew graduated MSci Mathematics (receiving the Royal Irish Academy “Hamilton Prize” for the best mathematics students in Ireland, in addition to numerous QUB examination prizes) and PhD in Theoretical Atomic Physics from Queen’s. He has expertise in theoretical and computational atomic and molecular physics, including positron and positronium interactions with atoms and molecules.

PhD students

Jaroslav Hofierka
PhD student (10/2019 —)

Jaroslav obtained a BSc in Physics and Masters degrees in Theoretical physics at the Charles University, Prague, Czech Republic. He is developing ab initio methods for positron-molecule interactions, as well as more general computational methodologies for diagrammatic many-body theory.

Jack Cassidy
PhD student (10/2020 —)

Jack was born and raised in Belfast, graduating 1st class Applied Mathematics and Physics at Queen’s (2020), receiving the William Blair Morton Prize and the Philip Burke Memorial Award. He began his PhD developing theoretical and computational methods for positron-molecule interactions in October 2020

Sarah Gregg

Sarah graduated MSci Mathematics from QUB in 2021. She will be joining the group in autumn 2021!

Honorary group members

Radha Green (born 2018)
Oisin Green (born 2019)

Radha and Oisin are currently developing a theory of everything. Radha has expertise in roaring like lions and dinosaurs. Oisin is conducting numerous thought experiments, and will share his insights when he can talk.
