Current PhD projects:

Epigenetic signatures of early-life events

MSc Weilong Li

The proposed project is the first large epigenomic study focusing on early life events and later life health. The project will be based on an existing collaboration network of Danish and Chinese scientists with expertise in studying complex diseases, genetic epidemiology, bioinformatics and public health.

Supervisors: Qihua Tan (EBB/SDU); Jan Baumbach (IMADA/SDU)

Epigenetic biomarkers as predictors of late-life mortality in the elderly

MSc Jesper Lund

The older section of the population increases at a steady pace especially in the western world including Denmark. Identifying risk factors that would allow improvements in population health and life expectancy is challenging issue in promoting healthy aging and longevity. 
A unique epigenomic data measured longitudinally on large Scottish old birth cohorts will be used for training and testing the models through collaboration in combination with a longitudinal Danish old birth cohort as an external validation.

Supervisors: Qihua Tan (EBB/SDU); Jan Baumbach (IMADA/SDU)

Female sex hormones and cognition in middle-aged and elderly Danish twins

MD Laura Ekstrøm Løkkegaard

Women have higher lifetime risk of developing AD than men. Additionally, women with AD tend to have lower cognitive function compared to men with AD. These sex differences raise the question of female sex hormones’ influence on cognition and risk of dementia. To study the association between female sex hormones and cognition in mid- and late life in Danish twins.

Supervisors: Kaare Christensen and  Jesper Hallas (SDU); Merete Osler (Copenhagen University)

Multivariate genome-wide association analysis of complex disease phenotypes

MSc Afsaneh Mohammadnejad

Current genetic association studies on complex phenotypes, e.g. cognitive function, metabolic syndrome, are based on association with each individual domain (test) separately or with a total score which is a simple sum up of all test scores on different domains. Multivariate association analysis that takes into account pleiotropic genetic effects jointly on the different domains with increased statistical power is actually missing.

Supervisors: Qihua Tan (EBB/SDU), Jan Baumbach (IMADA/SDU), and Tanja Maria Sheldrick-Michel (Dept. of Psychiatry/SDU)

Development and Sex-Disparity in Health Adjusted Life Expectancy in the European Population

MPH Camilla Riis Nielsen

Population ageing, the result of lower fertility rates and increasing life expectancy, is a global phenomenon and considered to be one of the greatest challenges of this century.
The aim of the project is to estimate the development in health adjusted life expectancy in the European Population using data collected from several European countries over 11 years (2004-2015) in SHARE (Survey of Health, Ageing and Retirement in Europe).

Supervisors: Rune Lindahl-Jacobsen, Kaare Christensen, Bernard Jeune, and Linda Juel Ahrenfeldt (EBB/SDU)

Cross-Cancer Relationships and Risk Factors of Hematologic Malignancies - a Twin Study

MSc Signe Bedsted Clemmensen

The aim of the project is to characterize hematologic malignancies in terms of genetic, environmental, and cross-cancer risk relationships varying in time using the population based Nordic twin cohort. To identify possible epigenetic markers of hematologic malignancies in a matched case co-twin study using epigenetic data from Danish twins. And to initiate a matched case co-twin study of risk of “ink-related cancers” using questionnaire exposure data.

Supervisors: Jacon v.B. Hjelmborg and Jonas Mengel-From (EBB/SDU); and Henrik Frederiksen, Odense University Hospital.
