PhD studentship: Songbird Neurogenomics


Supervised by Prof. David F. Clayton

This 3-year studentship is available from October 2013. The award will cover student fees and a tax-free stipend starting at 15,590 GBP per annum. Applications due by 31 January, 2013. A major research challenge in biomedicine and psychology is to work out the molecular and cellular processes that mediate long-term, experience-dependent changes in brain function. New techniques in genomics are revealing that natural experiences can trigger surprisingly complex and robust changes in gene expression in the brain. The general goal of Clayton’s research program is to understand the significance and function of these genomic changes, using a powerful animal model for high-order perception and cognition, the zebra finch. Zebra finches live in dense colonies and learn to recognize individuals through their vocalizations or songs” (reviewed in Clayton et al., 2009). Young zebra finches learn to produce vocalizations through a process of song tutoring by one or more older birds. Studies over the last 20 years have shown that song playbacks and other social interactions trigger complex gene expression changes in the auditory forebrain. This changing genomic response to song has been documented using microarray technology (Dong et al., 2009; Drnevich et al., 2012), extended to include analysis of microRNAs (Gunaratne et al, 2011) and further replicated using RNAseq techniques. These findings motivated sequencing of the zebra finch genome by Clayton and a large international group of collaborators (Warren et al., 2010). 

The student will begin by helping to design a project that will build on published and unpublished data describing changes in brain gene expression associated with social interactions and song learning in the zebra finch. The research will incorporate a mix of techniques, potentially including: behavioural manipulation and observation; bioinformatic and statistical analyses of Next Generation Sequencing (NGS) data; basic molecular biology (RNA purification, gene amplification and sub-cloning); neuroanatomical analysis of gene expression using in situ hybridisation and related techniques. The student will have opportunities to interact
with other investigators studying epigenetic mechanisms in neural and behavioural plasticity.

Location
Clayton’s lab recently moved from the University of Illinois (USA) to the School of Biological
and Chemical Sciences at Queen Mary, University of London, as part of a major effort to build
a unique environment for research in genomics, behavioral neuroscience and comparative
psychology. Queen Mary is located in London’s vibrant East End (10 minutes bicycle ride to
Tower Bridge; 10 minutes walking to Victoria Park), with easy access to the rich cultural and
scientific opportunities that London offers.
