  • Ingolf Bach

    Ingolf Bach, PhD

    Our research investigates molecular and epigenetic mechanisms of gene expression during cell fate specification. We use mouse embryogenesis as model system applying molecular, biochemical and genetic methods.

  • Jennifer Benanti

    Jennifer Benanti, PhD

    Our laboratory is interested in the molecular mechanisms that control how cells grow and divide. We are using genetics, biochemistry and cell biology, in both yeast and mammalian cells, to study how protein degradation by the ubiquitin proteasome system controls cell cycle and metabolic transitions.

  • Michael Brodsky

    Michael Brodsky, PhD

    We use Drosophila melanogaster as a model organism to study how cells distinguish between normal and dysfunctional chromosomes. We are particularly interested in how p53-dependent and p53-independent signaling pathways regulate apoptosis in response to DNA damage and unprotected telomeres.

  • Lucio H. Castilla

    Lucio H. Castilla, PhD

    Our laboratory studies how leukemia oncogenes alter cellular programs to transform hematopoietic stem and progenitor cells into a leukemia initiating cells. We combine genetic, biochemistry, and molecular biology approaches in transgenic mice and human cells to identify and characterize pathways deregulated by mutations in the members of the CBF gene family that redefine survival, self-renewal, and expansion of pre-leukemic progenitors. Recent efforts use this knowledge to develop high throughput small-molecule screens to identify inhibitors of oncoproteins that may be used as new drugs for improved therapies.

  • Thomas Fazzio

    Thomas Fazzio, PhD

    Our lab is focused on the identification of regulatory networks controlling gene expression in stem cells. In particular, we are interested in the roles of chromatin regulators in stem cell self-renewal and differentiation, and we take molecular, genomic, and biochemical approaches to understand these processes.

  • Heinrich Gottlinger

    Heinrich Gottlinger, PhD, MD

    The laboratory focuses on the late events in human immunodeficiency virus (HIV-1) replication, in particular on an endosomal budding machinery that HIV-1 co-opts to promote its egress from infected cells, and on the molecular mechanism by which the viral accessory protein Nef enhances the intrinsic infectivity of newly assembled virions.

  • Michael Green

    Michael Green, PhD, MD

    My laboratory is interested in understanding the molecular basis of human diseases—in particular cancer and certain rare genetic disorders—and identifying factors and regulatory pathways that can be therapeutically targeted to treat these conditions. In general our research focuses on identifying new factors and regulatory pathways that promote or prevent cancer, and modulating gene expression as a therapeutic approach. To pursue these interests we use transcription-based approaches, functional screens (such as genome-wide loss-of-function RNAi- and CRISPR-based genetic screens) and proteomics methods to identify new genes, proteins, and regulatory pathways that are the cause of or contribute to the disease state. In addition, we are interested in developing new gene therapy approaches for cancer and other diseases. 

  • Anastasia Khvorova

    Anastasia Khvorova, PhD

    Develop and characterize novel RNA chemistries to promote efficient oligonucleotide internalization and tissue distribution.

  • Nathan Lawson

    Nathan Lawson, PhD

    We are interested in how blood vessel identity is programmed. To investigate this process we take advantage of the zebrafish as a model system. We utilize genetic and molecular approaches to identify genes important for endothelial differentiation, while in vivo time lapse analysis allows us to visualize blood vessels as they form in a live embryo. Since this process is evolutionarily conserved, what we learn about blood vessel formation in the zebrafish will be relevant to human disease.

  • Brian Lewis

    Brian Lewis, PhD

    Primary pancreatic and liver cancers are deadly malignancies characterized by the rapid decline of patients after diagnosis. Work in the Lewis lab aims to elucidate the molecules and signaling pathways involved in tumor initiation, tumor progression and metastasis, and response to therapy in these tumors, using genetically engineered mouse models, cultured primary cells, and cancer cell lines.

  • Craig Mello

    Craig Mello, PhD

    Our lab uses the nematode worm C. elegans as a model organism to investigate how embryonic cells differentiate and communicate during development. In addition, we are investigating the mechanism of RNA interference, a form of sequence-specific gene silencing triggered by double-stranded RNA.

  • Erik Sontheimer

    Erik Sontheimer, PhD

    Biology and mechanism of RNA-based gene regulation; CRISPR interference; RNA-directed genome editing and gene control.

  • Heidi Tissenbaum

    Heidi Tissenbaum, PhD

    Our work in focused on understanding the molecular mechanisms involved in the aging process using a combination of genetics, molecular biology and biochemistry. Our long term goal is to increase the healthspan (the number of active, productive years before the onset of age-associated decline) of individuals; redefining middle age.

  • Eduardo Torres

    Eduardo Torres, PhD

    Our research interests are focused on understanding how aneuploidy affects cellular physiology and metabolism, and how aneuploidy influences cell evolution leading to further gross genomic alterations. Utilizing Saccharomyces cerevisiae as a model organism, we generated a series of aneuploid strains, each carrying an additional copy of 1 of the 16 yeast chromosomes and characterized their effects on cell physiology.

  • Yong-Xu Wang

    Yong-Xu Wang, PhD

    Our focus in the lab is to dissect the functional roles of nuclear receptor PPARs and their co-regulators in glucose and fatty acid metabolism and metabolic diseases, and to understand their molecular mechanisms of action. A combination of tools, including molecular biology, mouse genetics, physiology and genomics, will be employed.

  • Wen Xue

    Wen Xue, PhD

    "Our lab uses mouse models of cancer to investigate cancer genetics and treatment. We use CRISPR genome editing to functionally dissect cancer mutations in liver and lung cancer. Projects are ongoing to develop CRISPR tools to speed up cancer gene discovery and disease gene repair."
