Research interests:

My research interests are in Environmental sciences, public health, environmental epidemiology, demography methods, ethnic inequalities, mortality, and migration.

Career history:

Before my PhD, I did my masters in Environmental Sciences with a focus on Environmental Health at the American University of Beirut, Lebanon. My masters dissertation was on the topic of solid waste management in Lebanon and its policy implications. I also worked for one year as a research assistant after my masters studies in the field of public health and epidemiology.

Currently, I am in my final year of PhD where I investigate the effect of ambient air pollution on health and mortality by ethnicity in the UK. I am also working as a research fellow in the MigrantLife project where I investigate the family, employment and housing dynamics among immigrants in Europe.

Active research projects:

The title of my thesis is as follows: Air Pollution, Health, Mortality, and Ethnicity: Analysis of Longitudinal and Census Data from the United Kingdom with High-Resolution Spatial Data

In this PhD project, I investigate the impact of multiple air pollutants on health and mortality by ethnicity using individual-level census and longitudinal data linked to high-resolution air pollution data from the UK.
