Haykanush Ohanyan

Haykanush was a PhD candidate at the department of Epidemiology and Data Science at Amsterdam UMC and Institute for Risk Assessment Sciences at University of Utrecht University. The main focus of her thesis was related to adapted machine learning approaches to study relationship between the factors of general external exposome and cardiometabolic diseases.

Decoding the exposome

Decoding the exposome

The environment we live in has a dominant impact on our health. It explains an estimated seventy percent of the chronic disease burden. Where we live, what we eat, how much we exercise, the air we breathe and whom we associate with; all of these environmental factors play a role. The combination of these factors over the life course is called the exposome. There is general (scientific) consensus that understanding more about the exposome will help explain the current burden of disease and that it provides entry points for prevention and ...
