Dr Tahania Ahmad

Profile

I am a Postdoctoral Research Fellow at the Centre for Cancer Screening, Prevention and Early Diagnosis, QMUL. My research focuses on using large-scale routinely collected health data to investigate cancer risk, diagnostic pathways, and inequalities in cancer outcomes, with a particular focus on socioeconomic deprivation and ethnicity.  I am currently working on an international breast cancer risk prediction project (B2Risk), which aims to improve risk stratification by incorporating hormonal and biological markers into existing risk prediction models. Additionally, my focus extends to understanding the risk factors associated with oesophageal cancers and elucidating variations across different countries. 

I completed a PhD at QMUL on multimorbidity in cancer survivors in the UK, using linked primary and secondary care data to examine long-term health outcomes, multimorbidity patterns, and healthcare utilisation across multiple cancer types. This work developed into a broader research focus on ethnic and socioeconomic inequalities across the cancer pathway, including differences in survival, comorbidity burden, and healthcare use before and after cancer diagnosis. 

Prior to my PhD, I worked for seven years as a medical statistician in NHS clinical trials and academic units, with experience across intensive care, surgery, and maternity research. I hold an MPH in Public Health (Epidemiology) from Imperial College London and a Diploma in Advanced Statistical Methods in Epidemiology from the London School of Hygiene & Tropical Medicine. I supervise MSc students on their dissertations, contribute to peer review for international journals, and have presented my research at national and international conferences. My overarching research aim is to generate evidence that improves early cancer detection and reduces inequalities in cancer outcomes through better use of routinely collected data.

Research Interests:

My research focuses on cancer epidemiology, early detection, and diagnostic pathways using routinely collected primary care data. I also have interests in developing cancer risk models and risk-stratification.
