After studying biochemistry, pre-clinical medicine and neurosciences in Germany, Jonny joined Greg Jefferis' group at the MRC Laboratory of Molecular Biology in Cambridge, UK, for his PhD. There, he worked on sexually dimorphic pheromone processing in Drosophila and developed novel strategies for ultra-fast labelling of tissues. He was awarded the Max Perutz Prize for his PhD work.
He subsequently joined Catherine Dulac's lab at Harvard as a postdoc – supported by fellowships from EMBO, HFSP and the Wellcome Trust – where he focused on deconstructing the neural circuits underlying parental behavior in male and female mice. He has been continuing this work in Tiago Branco's group at the Sainsbury Wellcome Centre for Neural Circuits and Behaviour, supported by a NARSAD Young Investigator Grant.
From early 2019, he will head the newly established State-dependent neural processing Laboratory at the Francis Crick Institute.
