My work in pure mathematics focuses on Homological Algebra over commutative rings:
Commutative Algebra of Singularities, Local Cohomology, Tight Closure and Positive Characteristic Methods.

Having conducted research in both Mathematics and Statistics, I am currently interested in the interactions between these fields, and in particular, in the applications of spatial statistics and of machine learning to Health research. My research in Mathematics focuses on Homological Algebra over commutative rings.

Before taking up my MRC SDF fellowship I was an NIHR Research Methods Fellow in Statistics. During my NIHR fellowship I worked on identifying measures of hospital performance and quality of care, based on the analysis of large routine observational datasets.

As an MRC Skills Development Fellow, I'm interested in the spatial epidemiology of alcohol availability, consumption and harm. Alcohol misuse has been one of the major public health concerns in the UK as a significant source of health and social problems. Much research has gone into identifying, qualifying, and quantifying factors that lead to alcohol misuse, and their impact on health. Nonetheless, the extent of the impact of some of these factors, is still not fully understood, the geographical availability of alcohol being one of them.

My MRC Skills Development Fellowship project proposes to understand the public health impact of geographical alcohol availability in the UK. It proposes to investigate the spatial relationship between availability, harm, and consumption, and in particular, to characterise the spatial aspects of the relationship between demographics and outlets that are responsible for harm and problematic consumption. During my fellowship, I will acquire new skills in spatial statistics, mathematics, geographical data science, and machine (deep) learning algorithms. My plan is to develop new methods where current methods are lacking and then apply these to address real public health problems.

I joined the University of Sheffield in 2012 as an EPSRC Research Associate working on
Commutative Algebra of Singularities, Local Cohomology, Tight closure and Positive Characteristic Methods.
I received my PhD from the University of Nebraska-Lincoln under the advising of Luchezar Avramov.
