Christian received both his MS degree in Molecular Genetics and his PhD in Neuroscience from the University of Bonn in Germany. During his PhD he identified microRNAs that regulate expression levels of genes involved in migration of cerebellar granule cells in mice. At Rockefeller University he switched from murine cerebellar development to human embryonic stem cell (hESC) research to understand the inherited neurodevelopmental disorder known as Huntington’s disease (HD). Now at the Lub Lab Christian looks forward to integrating his knowledge from human ES cell signaling to create human complex skin with appendages.
