• Mathematical modelling of cancer progression and treatment strategies
• Drug delivery, optimal sequencing and scheduling of cancer therapies
• Discrete and hybrid computational models in cancer growth
• Modelling inter- and intra-cellular dynamics
• Studying radiation and radiation bystander effects
• Radioecology

 My research is very much interdisciplinary and some of the main highlights of my research include:

• Development of Multiscale Modelling Framework: I am currently developing an individual-cell based multiscale modelling framework to study the growth and progression of cancel cells and their reposes to therapy. This is framework is currently being used by several external research groups to study Tuberculosis, 3D cell printing and cancer treatment response. The model and the framework is continuously being updated.
• Involvement in Radioecology: I am currently involved in a focussed radioecology subgroup supported by International Union of Radioecology. The overall aim of the subgroup is to understand the effects of radiation (primarily low dose radiation) in an ecological context. 
• Clinical and Industrial Collaboration: I work closely with clinical and experimental groups with an aim to develop a biologically and clinically relevant mathematical and computational models. My collaborators include South West Wales Cancer Centre and Institute of Cancer Research. Recently, I started working with AstraZeneca to study the effects of an anticancer drug and GSK to study HIV treatment modelling.
