I am an epidemiologist, with an interest in using statistical and mathematical methods to gain an understanding of infectious disease prevalence, distribution and spread. Currently I am a Research Fellow at the London School of Hygiene and Tropical Medicine.

Research Interests

Seroepidemiology of Klebsiella pneumoniae

My current research focuses on the global distribution of capsule and O types of Klebsiella pneumoniae as a causative agent of neonatal sepsis. Sepsis is a leading cause of newborn deaths globally, with around 20% being caused by K. pneumoniae. Capsular polysacharrides are ideal vaccine targets, however in K. pneumoniae this is notably very diverse (> 100 K loci). Using Bayesian statistical methods, I have been exploring the potential composition required for a maternal 20 valent vaccine to protect against 70% of capsular types seen in neonates in Africa and South Asia. The initial phase of this work has been recently published, and there is ongoing follow ups exploring how these estimates can be weighed to ensure a more equitable vaccine coverage, based on a range of factors such as population, birth rates, case fatalities and more.  I am also exploring the impact of study design across multiple spatial scales with the goal of understanding the impact of number of study sites and heterogeneity of study sites on national and regional estimates. A key consideration is ensuring that monitoring cases in done in the most effective manner possible in resource limited areas. 

Antimicrobial Resistance in African Animal Trypanosomiasis (AAT)

At the University of Glasgow, I worked on mathematical models exploring the spread of antimicrobial resistance in Trypanosoma congolense, which causes African Animal Trypanosomiasis in cattle. I built deterministic models (ODEs) to simulate how different treatment strategies — both therapeutic and prophylactic — influence resistance dynamics across Tanzanian farms. This work remains close to my interests in agricultural disease systems and policy-relevant modelling, and is still ongoing.
