About Dr. Navin
Dr. Navin is an associate professor at the M.D. Anderson Cancer Center, with a joint appointment in the Department of Genetics and the Department of Bioinformatics. He is also the co-director of the Sequencing and Microarray Core Facility at MD Anderson. I conducted my graduate training and postdoctoral training at the Cold Spring Harbor laboratory under the mentorship of Dr. Michael Wigler. During this time, he invented the first single cell DNA sequencing method (Single-Nucleus-Sequencing) for sequencing the genome of a mammalian cell (Navin et al. 2011, Nature.). This work played a pivotal role in establishing the field of single cell genomics. The Navin laboratory continues to be at the forefront of the single cell cancer genomics field, where they have discovered a punctuated model of copy number evolution in triple-negative breast cancer (Gao et al. 2016, Nature Genetics) and elucidated the role mutator phentoypes and subclonal mutations in breast cancer evolution (Wang et al. 2014, Nature). Dr. Navin’s group continues to pioneer the developing novel technologies for performing single cell DNA and RNA sequencing, in addition to innovative computational and statistical methods for analyzing the resulting large-scale datasets. These methods are being applied to study cancer evolution in the context of invasion, metastasis and therapy resistance. His laboratory works closely with leading oncologists and pathologist at MD Anderson to translate these technologies into the clinic, where they are poised to make a major impact on reducing the morbidity in human patients. Dr. Navin has been the recipient of many prestigious awards in recognition of his work, including the Damon-Runyon Innovator Award, AAAS Wachtel Award, ACS Research Scholar Award, Wilson Stone Award and the Randall Innovator Award.

Single-cell sequencing Genome Evolution in cancer Intratumor Heterogeneity Cancer Genomics Computational Biology and Bioinformatics
My goal is to understand genome evolution in human cancers. As tumors evolve from a single cell, they acquire complex somatic mutations and diverge to form distinct lineages and subpopulations. This intratumor heterogeneity confounds basic research and clinical diagnosis, because tools do not exist to resolve it. To address this problem, we developed a single-cell sequencing method to profile genomic copy number in individual tumor cells ( Nature 472:90-4, 2011). I used this method to profile hundreds of single cells in two breast cancer patients to delineate clonal diversity and infer patterns of genome evolution. The data revealed multiple clonal subpopulations that shared a common evolutionary lineage. In contrast to the gradual models of tumor progression, the data suggest that these breast tumors grew by punctuated clonal expansions, in which hundreds of genomic rearrangements were acquired in short bursts of evolution. We have also recently developed a powerful new method to perform whole-genome sequencing on single tumor cells. This will enable us to study the evolution of many different classes of somatic mutations (point mutations, indels and structural variants) at base-pair resolution in single cells. In addition to single cell sequencing, my laboratory also uses many genomic and cytological methods to study how cancer genomes evolve. We are also actively developing new computational methods to quantify tumor heterogeneity and understand if these measures correlate with clinical parameters such as survival and resistance to chemotherapy. One method developed is called Ploidy-Seq to deep-sequence intratumor subpopulations and infer mutational chronology and ancestral tumor genomes.
