Peggy Ler

I completed a PhD at the Department of Medical Epidemiology and 
Biostatistics in November 2024. Using data from the Swedish Twin Registry and US Health Retirement Study, my doctoral thesis examined body mass index and metabolic health factors from midlife to late life, and their 
potential impact on biological aging.

Since 2021, I am an affiliate of the National Graduate School on Ageing and
Health (SWEAH).

I have a master’s degree in medical science with a major 
in global health from the Karolinska Institutet. I also have a Bachelor’s 
degree in Science, with a major in Respiratory Therapy from The 
Ohio State University completed under a four-year overseas scholarship
granted by Singapore General Hospital.
