Urban dynamics and policy

“The ballet of the good city sidewalk never repeats itself from place to place, and in any one place is always replete with new improvisations.”

Jane Jacobs

About me

Originally from Dublin, I am currently a Senior Research Fellow at the Mathematical Institute at the University of Oxford. My research focuses on economic development and the emergence of complexity for urban systems.

I was previously a Fulbright Scholar and Postdoctoral Research Fellow at the Center for International Development at the Harvard Kennedy School following my PhD (mathematics) at Imperial College. I am also founder and Editor in Chief of Angle – a journal based at Imperial College focusing on the intersection of policy, politics and science – since 2009. More …

PEAK Urban

PEAK Urban is a 4 year international multidisciplinary programme funded by the Global Challenges Research Fund (RCUK GCRF) involving researchers at the University of Oxford, Peking University, University of Cape Town, the Indian Institute for Human Settlements, and EAFIT University (Colombia).

The team from the Oxford Mathematical Institute will focus on studying cities as complex social, spatial and economic systems, with particular themes including knowledge diffusion, skills and agglomeration economies, industrial complexity and urban form. We will use a broad range of analytical tools from network science to machine learning. 

The Bo-Kaap or Malay Quarter in Cape Town, a former township that has been rejuvenated due to government support.


My research lies at the intersection of a number of fields including urban systems, economic complexity and economic geography, development, and network science.
