In addition, he is the Associate Director for Novel Technologies at the JP Sulzberger Columbia Genome Center. Dr. Sims completed his graduate and postdoctoral studies in the laboratory of Prof. Sunney Xie at Harvard University, where he developed tools for making single molecule measurements in individual cells and a novel, microfluidics-based platform for next-generation sequencing. His laboratory at Columbia specializes in single cell analysis and uses cutting-edge microscopy, sequencing techniques, and microfluidics to conduct large-scale single cell studies in malignant tumors and developmental systems.
