Our research on evaluating responses to COVID-19 informational social media adverts is now published online at the Journal of Applied Research in Memory and Cognition.
I participated in the Serrapilheira/ICTP-SAIFR Training Program in Quantitative Ecology in São Paulo, teaching a mix of undergraduate and masters students from different backgrounds about principles and modelling in predator-prey dynamics, evolutionary ecology and epidemiology. I also gave talks on "Applying quantitative principles to develop public facing tools for COVID-19" and "How does code and science get published?".
The Journal of Open Source Software published our paper describing the localcovid19now R package. The package provides functions to download and map recent localised COVID-19 case data in an effort to improve the understanding of localised COVID-19 transmission.
Slate featured an op-ed, written with Joshua Weitz, about reporting lags and the interpretation of case data, and the possibility of epidemic plateaus in Georgia.
Our paper modelling the potential of "serological shielding" is now publsihed in Nature Medicine.
Press: WABE covers our intial COVID-19 projections in Georgia using MAGE.
We released an executive summary report for Georgia on the potential for COVID-19 to return if physical distancing interventions are lifted too soon using a metapopulation age-structured epidemiological model (MAGE).

I gave the Microbial Dynamics seminar at Georgia Tech on our work on estimating mortality in marine microbial communities.
I presented our work on modelling microbial populations in the North Pacific Subtropical Gyre at Ocean Sciences Meeting 2020 in San Diego.
I gave the Physics of Living Systems seminar titled: "Quantifying the ecological relevance of grazing and viral lysis in marine microbial communities".
Our new paper describing how biogeochemistry relates to changes in sea surface height at Station ALOHA is now published in the Journal Of Marine Research.
Our new paper about size-dependent encounter rates between microbes and their predators is now published at Frontiers in Marine Science. I wrote a summary here.
Was on hand to discuss the Science.Art.Wonder project today (and on 23/03/2019 at the Atlanta Science Festival) with Emily Madsen. One piece "Submerged" explores the capacity for viruses to affect marine ecosystems; whilst the second, "Through a different Model" focuses on the process and art of modelling using a size-structured phytoplankton model I am developing as an example.
Curated the @biotweeps twitter account for a week where I enthused about modelling and marine viruses!
I have been promoted to Research Scientist I at Georgia Tech.
Hosted Emily Madsen in the WeitzLab to discuss communicating my research through art as part of the Science.Art.Wonder project.
I gave a talk at the SCOPE annual meeting titled: "Diel with it: Data-model comparisons of diel ecological oscillations around station ALOHA".
I volunteered with Habitat for Humanity in Atlanta.
I presented "Viral Lysis vs. Grazing: perspectives on phytoplankton mortality” at the 5th Georgia Tech Postdoctoral Research Symposium.
Our new paper on modelling the robustness of dilution based estimates of rates of viral-induced mortality is now published in Frontiers in Microbiology. I wrote a summary here.
I am a Visiting Associate Research Scientist in the 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. My current research interests lie in investigating the ecology of aquatic microbial communities. 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.
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.
