Sanjay Srivatsan is completing his dissertation research in the laboratory of Dr. Cole Trapnell in the Department of Genome Sciences. In collaboration with the laboratories of Drs. Jay Shendure in Genome Sciences and Kelly Stevens in Bioengineering, his research has focused on developing high throughput single cell RNA sequencing technologies, employing “sequential combinatorial indexing.” In an initial application, Sanjay used this approach to perform a massively multiplex assay to quantify global transcriptional responses to drugs in individual cells. More recently, he has developed a new method for sequencing mRNA transcripts at near single cell resolution in developing embryos. His research has led to an atlas of gene expression that has the potential to revolutionize the understanding of mammalian development with attendant clinical implications for birth defects and other developmental disorders.
