Link to my CV: Download

I am an Associate Research Scientist in the Quantitative Viral Dynamics group at the University of Maryland. I use mathematical and computational methods to investigate and solve ecological and environmental problems. In this sense, I like to term myself a computational ecologist. Overall, my approach is inherently interdisciplinary and focuses towards translational research backed up with open-source coding practices. My current research interests lie in investigating the ecology of aquatic microbial communities; and advancing the integration of infectious disease dynamics and human behaviour.

Previously, I graduated with a BSc (Hons) in Geography and Mathematics from the University of Leeds in 2010, an MRes in Mathematics in the Living Environment from the University of York in 2011 — during which I completed a research internship with the Computational Science Lab at Microsoft Research in Cambridge. I earned my PhD in Biological Sciences from the University of Exeter in 2015. Following this, I made a transatlantic move to the School of Biological Sciences at Georgia Tech. where I was a Postdoctoral Fellow (2015-2019), Research Scientist I (2019-2022) and Research Scientist II (2022-2023) before moving to the University of Maryland.

I believe one step towards making science more available in general, is to provide free and open access to research materials. I do not agree with the predominantly expensive open access options provided by many publishers, but am a strong advocate of making pre/post-prints of my research available. If I write a paper, I would sure like to make it as easy as possible, for as many people as possible, to be able to read and use the information discovered! Specific journal policies on this matter can be found using SHERPA/RoMEO.

In my spare time I enjoy being in the great outdoors, especially on the coast. Some of the other things I like to do are playing the harmonica (badly), reading books and playing computer games. Chances are, I am thinking about the sea right now.

Quantifying Microbial Mortality

There are estimated to be over 10³⁰ viruses of prokaryotic bacteria, known as bacteriophage or just phage, in the worlds oceans (Suttle, 2005) which makes them an important component of the global marine ecosystem and ocean biogeochemistry. However, there are diverging estimates of virus-induced mortality relative to grazing-induced mortality in marine microbiology. My research focuses on better quantifying microbial mortality processes – with a particular interest in cyanobacteria – as differing mortality pathways have different biogeochemical consequences. In general, a goal is towards improving understanding and representation of mortality processes in marine microbial populations, and in larger ecosystem models.

Ecological Dynamics and Community Structure

Ecological communities are composed of multiple types of organisms and interactions. Emergent dynamics of these communities are a function of the ways in which these interactions are organised and structured within a community. A particular interest is considering surface marine microbial communities where day-night cycles and life-cycle oscillations of photosynthesisers tend to synchronize. How does the community organise around such constraints? Additionally, microbial systems tend to be those in which (co)evolutionary dynamics can occur on ecological timescales.

Pandemic Response and Preparedness

Behavioral feedback is a critical component in understanding transmission dynamics of communicable diseases, including COVID-19, and can be influenced via policy and individual decision making. My research focuses on how leveraging data can lead to improve understanding of pandemic-associated risks, and aid decision making and outbreak mitigation.
