Dann Mitchell (Professor of Climate Science and Met Office Chair in Climate Hazards)

In 2016 I joined the University of Bristol faculty and established the Bristol Climate Dynamics group. Before joining Bristol I undertook 4 years of postdoctoral research in the University of Oxford’s Department of Physics (AOPP), having already completed a PhD in the University of Reading’s Meteorology department.

At Bristol, I hold the Met Office Chair in Climate Hazards, and coordinate the partnership between our two institutes. My research interests are focussed around weather and climate extremes, and how they impact society. I look into the future at climate projections, but also into the past, at climate attribution. My research starts with atmospheric circulation patterns, especially those relating to extreme weather, and ends with impacts. I have a strong focus on climate and health, for instance the health hazards from, heatwaves, flooding, or tropical cyclones. I also like to dabble in the atmospheres of other planets, especially Mars.

Rachel James (Associate Professor in Climate Science, UKRI Future Leaders Fellow)

My research focuses on African climate systems. I’m trying to find out more about how climate is changing now, and what further changes we can expect in the coming years and decades. This work is designed to inform climate change policy and planning. Before joining Bristol in 2020, I worked at University of Oxford and University of Cape Town. I’ve recently been awarded a UKRI Future Leaders Fellowship, and over the next 4-7 years I’ll be working with my team to improve climate information for climate change adaptation, bringing together new climate science analysis with insights from psychology and risk communication. Read more about the SALIENT project here.

Peter Watson (Senior Lecturer, NERC Independent Research Fellow)

The main focus of my work is understanding the risks posed to society by extreme climatic events and how these are being affected by climate change. In particular, I work on producing, evaluating and applying physically-based simulations of the atmosphere and climate, with a focus on understanding extreme atmospheric weather systems. One of my partnerships is with climateprediction.net, who use distributed computing to produce very large simulation datasets containing thousands of examples of possible weather systems, facilitating the study of extremes (you can even volunteer your own computer’s time for this, if you would like). Past work of mine has included leading the scientific development of a high-resolution global atmospheric model (by the standards of typical models) to use in that system. Before joining Bristol, I did my PhD and postdoc work at the University of Oxford.

My work also includes improving our climate and weather simulators and post-processing of their output by using machine learning approaches. This is cross-disciplinary work with partners in computer science and industry.

GROUP Postdocs

Eunice Lo

I am interested in climate variability and change, and their impacts on human health. The goal of my research is to generate scientific evidence to inform climate adaptation and mitigation policies, so that fewer people will be adversely affected by climate change. Since joining the Bristol Climate Dynamics Group in 2017, I have been investigating the impacts of extreme temperatures (e.g. heatwaves) on human mortality. I have recently joined the wider university research institutes as a Research Fellow in Climate Change and Health. I am keen to expand my research to other climate exposures and form new collaborations with researchers from health sciences.

Ailish Craig

My research explores climate services in southern Africa. A key focus of my work is to bridge the gap between climate model data and decision makers. This work will ensure decision makers have access to understandable and accurate climate information that can be used to inform national climate adaptation plans. The research is interdisciplinary, taking theories and methods from geography, risk communication and environmental psychology. Read more about the SALIENT project here.

Before joining Bristol in 2023, I undertook my PhD at the University of Southampton. My thesis explored social capital in Malawi and how it is used to alleviate hunger whilst also considering differences over time and between genders.

GROUP PhD & MScR Students

Emily Vosper

I am currently studying for a PhD which draws together ideas from the fields of Artificial Intelligence and Climate Change Science. Last year I undertook a Master’s by research project where I investigated the future impacts of hurricane rainfall on the Caribbean and found that as extreme hurricane rainfall events will be less likely if global temperatures are stabilised at 1.5°C compared to 2°C above preindustrial levels. I am currently looking at using machine learning to estimate heat-related mortality in countries with sparse data.

Henry Addison

I’m a PhD student in Interactive Artificial Intelligence at the University of Bristol. I have spent time in both academia and industry, including degrees in Mathematics and Computer Science and working for many years as a software developer. I joined the group for my PhD as I am interested in applying AI to climate science. I’m currently looking at ways of using machine learning to produce high-resolution precipitation projections more cheaply and ensuring the work benefits producers and consumers of projection datasets.

Daniel Cotterill

I joined the Climate Dynamics Group as a PhD student, whilst working at the UK Met Office as a Climate Scientist in the Climate Detection and Attribution team. My main research interests are focussed on climate change extremes, in particular extreme precipitation changes over the UK and the translation of these into Flooding Impacts. I am also interested in changes in weather patterns over the European region and their implications for different weather hazards.

Dan Green

My interests lie in changes to extreme weather and climate in Africa, with my PhD research examining tropical cyclones in the Mozambique Channel. I am keen to investigate their representation in climate models, what changes we could expect to the characteristics of these events in the future and the impacts this could have for southern African communities. My Master’s by Research project focused on a pan-African assessment of mean and extreme temperature, and I remain eager to expand my research in this area. I am excited to engage with the public about climate science and change through my role as a Climate Outreach Ambassador, and have enjoyed working on the development of net-zero policies with local organisations in Bristol. I am passionate about biscoff & bagels, trying to avoid running up hills and live music.

Regan Mudhar

I am a PhD student at the University of Exeter, having graduated from the University of Bristol in 2019 with a MSci in Physics with Astrophysics. Will Seviour and Dann Mitchell co-supervised my masters project (with Zoë Leinhardt) on building a climate model of Titan’s atmosphere, and are now two of my current PhD supervisors. As part of the ArctiCONNECT project, I am using the modelling framework Isca to study the impacts of Arctic amplification on the stratosphere.

Sofia Samoylova

I am currently pursuing my PhD, focusing on the impact of maternal heat exposure on preterm birth rates. My research utilises both human data and Diploptera punctata as a model organism. Having obtained a background in Biochemistry (BSc) and Medical Biosciences (MSc), my research interest developed into investigating the effects of the maternal environment on progeny and understanding the mechanisms at play.

Abi Jones

I am a current PhD student in the School of Geographical Sciences. My research focuses on future changes in intense storms across Africa in new km-scale climate scenarios. I will be working with the Met Office’s Convection-Permitting 4 Africa (CP4A) model to determine how the characteristics of intense storms are likely to change in the future, and what this might mean for extreme rainfall events.

Having pursued degrees in Geography (BA) and Climate and Society (MA), as well as working at both research institutes and humanitarian organisations, my interests lie more broadly at the intersection between climate science, climate services, and humanitarian action, specifically in relation to extreme events.
