Research & Current Projects


I work on the evolutionary ecology of ageing and senescence, sex differences, and nutritional effects, using experimental and theoretic approaches to study these questions on the phenotypic and genetic level.

Information on my previous projects and ongoing involvements can be found on my website: felix.zajitschek.net
