Profile

My research centres around interdisciplinary statistics tackling challenges by science and engineering, often with the aim to achieve impact through collaboration with industry. I am Deputy Directory of the Centre for Applications of Mathematical & Computing Sciences (CAMaCS).Link opens in a new window I am a member of the core team of the Health SpotlightLink opens in a new window, one of six recently launched Interdisciplinary Research Initiatives,Link opens in a new window and I lead the Health & Technology team. I am a Senior Fellow of the Higher Education Academy (SFHEA) and a Fellow of the Warwick International Higher Education Academy (WIHEALink opens in a new window).

Research

My passion lies in interdisciplinary, project-oriented work, collaborating with scientists and engineers from fields such as infrastructure, genomics, biochemistry, microscopy, neuroscience, ecology, public health, and medicine. As a statistical data scientist with a foundation in probability and ergodic theory, I see each data analysis challenge as an opportunity to develop general methods applicable to similar situations.

I am particularly interested in modeling uncertainty in novel high-throughput measurement processes, such as spatially distributed structural monitoring sensors (in bridges or train tracks), genome-scale transcriptomics, and wearable devices. Insights from these technologies can support health monitoring—of both engineered structures and people—and drive scientific discoveries.

Methodologically, my recent research projects have involved spatial statistics, extended regression models, high-dimensional data capture, quality assessment and normalisation, topological data analysis, decision algorithms, and subjective and objective approaches to risk and uncertainty.

I have also been leading I am leading the WIHEA-funded WUSTLink opens in a new window project. We develop an online toolbox facilitating students taking more control of their academic success while simultaneously providing learning-by-applying opportunities for a wide range of skills.

Supervision

I currently have the capacity for PhD supervision and welcome inquiries about research projects. I tend to design projects linked to real-world applications and select methodologies that best fit the challenges defined by the data and the research objectives.

11 of my PhD students have graduated and I am currently (co-)supervising 3. I have supervised about 60 Master level projects primarily at Warwick (MMORSE, MMathStat, MSc Statistics) and a few in other institutions (Masters in Statistics, Masters in Epidemiology). I have also supervised 7 third-year Data Science projects.

Previously supervised topics have spanned a wide range of domains, including behavioral decision-making under risk and uncertainty (e.g., medical treatment, financial investment, admissions), genomics, image data (e.g., X-ray, microscopy, brain imaging), medical statistics (e.g., cancer screening, survival predictors, trial design), and infrastructure projects (e.g., project data analysis, health monitoring of engineered structures).

Short biography

I am a Professor at the Department of Statistics at the 神马福利影片 where I previously worked as a Reader (2021-2025), Associate (2010-2021) and Assistant Professor (2007-2010). I am an Alumna Fellow of the , the UK's National Institute for Data Science and AI.

Previously, I held a joint appointment as an Assistant Professor at the Departments of Math/Stats and of Community Health/Epidemiology & Cancer Research Institute, Queen's University, Canada. I was a visiting Assistant Professor and Research Statistician at the Department of Statistics at the University of California at Berkeley, USA. I held a Postdoctoral Fellowship in Computational Biology at Eurandom at the TU Eindhoven in the Netherlands.

My PhD (2001) was in Mathematics, with a thesis on large deviations in statistical mechanics models, supervised by Prof. H. F枚llmer, Humboldt University Berlin, Germany. I got a Master's degree in Mathematics with a thesis about measure-valued diffusions and quasilinear Dirichlet problems supervised by Prof. H. F枚llmer and minor qualifications in Computer Sciences and Psychology, at the University of Bonn, Germany.
