About Tahir Taj

I am an epidemiologist with expertise in environmental and chronic disease epidemiology, focusing on diet, urological cancer risk, and environmental exposures. My work involves register-based research and large-scale epidemiological studies, where I analyze complex health data to better understand the role of environmental and lifestyle factors in disease development.

Currently, I work as an epidemiologist at Örebro University Hospital, supporting various medical and public health research projects by providing expertise in study design, data analysis, and statistical modeling. In addition to assisting other researchers, I am actively conducting my own research on the association between diet and the risk of urological cancers, as well as exploring the health effects of environmental exposures, including air pollution and chemical contaminants.

Research Focus
My research aims to improve public health by identifying and understanding modifiable risk factors for chronic diseases. Key areas of focus include:

• Diet & Cancer Risk: Investigating how dietary patterns and nutritional factors influence the development of urological cancers.
• Environmental Exposures & Health: Studying the long-term impact of air pollution, PFAS, endocrine disruptors, and other chemical exposures on human health.
• Chronic Disease Epidemiology: Examining risk factors for kidney disease, cardiovascular disease, and cancer through register-based studies.
• Epidemiological Methods & Data Science: Utilizing Swedish national health registers to conduct population-based epidemiological research.

Teaching & Mentorship
I am passionate about education and have taught courses in epidemiology, environmental health, and public health research methods at both the undergraduate and graduate levels. I also provide mentorship to Master’s and Ph.D. students, particularly in register-based research, statistical analysis, and causal inference techniques.
