Discovery of phenotypes influenced by the season of birth

Background: It has been evidenced for model organisms, e.g. mouse, that the perinatal photoperiod can have long term influence on behaviour and regulation of the Circadian clock genes.

Goal: The goal of this project is to use the Cohorte Lausannois (CoLaus) data to discover phenotypes with statistical evidence of being influenced by the season of birth of the individual. Special emphasis will be on psychological traits.

Mathematical tools: Statistics. The students will learn how to use Matlab to read in large data sets, conduct linear and logistic regression analysis.

Biological or Medical aspects: The effect of imprinting on complex human traits is poorly understood, we aim to elucidate a special aspect of it.

Supervisors: Zoltan Kutalik & Diana Marek

Students: Loic Spinazza & Charles Lehmann
