BioThe Abu-Remaileh Lab is interested in identifying novel pathways that enable cellular and organismal adaptation to metabolic stress and changes in environmental conditions. We also study how these pathways go awry in human diseases such as cancer, neurodegeneration and metabolic syndrome, in order to engineer new therapeutic modalities.
To address these questions, our lab uses a multidisciplinary approach to study the biochemical functions of the lysosome in vitro and in vivo. Lysosomes are membrane-bound compartments that degrade macromolecules and clear damaged organelles to enable cellular adaptation to various metabolic states. Lysosomal function is critical for organismal homeostasis—mutations in genes encoding lysosomal proteins cause severe human disorders known as lysosomal storage diseases, and lysosome dysfunction is implicated in age-associated diseases including cancer, neurodegeneration and metabolic syndrome.
By developing novel tools and harnessing the power of metabolomics, proteomics and functional genomics, our lab will define 1) how the lysosome communicates with other cellular compartments to fulfill the metabolic demands of the cell under various metabolic states, 2) and how its dysfunction leads to rare and common human diseases. Using insights from our research, we will engineer novel therapies to modulate the pathways that govern human disease.

Current Research and Scholarly InterestsWe examine how cells communicate and function during fetal development. The work in my laboratory focuses on the establishment of specific cell fates using genomics to decipher interactions between chromatin and developmental signaling cascades, between genomes and rapidly evolving cell types, and between genomic copy number variation and gene expression. In recent years we have focused on the vastly understudied biology of the trophoblast lineage, particularly how this lineage evolved.
Associate Professor of Genetics
Current Research and Scholarly InterestsOur lab studies how intricate control of gene expression and cell signaling is regulated on a minute-by-minute basis to give rise to the remarkable diversity of cell types and tissue morphology that form the living blueprints of developing organisms. Work in the Barna lab is presently split into two main research efforts. The first is investigating ribosome-mediated control of gene expression genome-wide in space and time during cellular differentiation and organismal development. This research is opening a new field of study in which we apply sophisticated mass spectrometry, computational biology, genomics, and developmental genetics, to characterize a ribosome code to gene expression. Our research has shown that not all of the millions of ribosomes within a cell are the same and that ribosome heterogeneity can diversify how genomes are translated into proteomes. In particular, we seek to address whether fundamental aspects of gene regulation are controlled by ribosomes harboring a unique activity or composition that are tuned to translating specific transcripts by virtue of RNA regulatory elements embedded within their 5’UTRs. The second research effort is centered on employing state-of-the-art live cell imaging to visualize cell signaling and cellular control of organogenesis. This research has led to the realization of a novel means of cell-cell communication dependent on a dense network of actin-based cellular extension within developing organs that interconnect and facilitate the precise transmission of molecular information between cells. We apply and create bioengineering tools to manipulate such cellular interactions and signaling in-vivo.

Current Research and Scholarly InterestsWe are using Saccharomyces cerevisiae and Human to conduct whole genome analysis projects. The yeast genome sequence has approximately 6,000 genes. We have made a set of haploid and diploid strains (21,000) containing a complete deletion of each gene. In order to facilitate whole genome analysis each deletion is molecularly tagged with a unique 20-mer DNA sequence. This sequence acts as a molecular bar code and makes it easy to identify the presence of each deletion.

Assistant Professor of Genetics
BioLivnat Jerby is an Assistant Professor of Genetics at Stanford University. Her research focuses on multicellular dynamics, as a disease driver and therapeutic avenue, particularly in the context of cancer immunology. In her work, she aims to identify the drivers, molecular underpinnings, and causal structure of multifactorial immune evasion mechanisms, and use this information to identify new and more effective ways to augment and unleash targeted immunity via combinatorial interventions. To address this challenge at scale, she develops integrative approaches, fusing single-cell sequencing and imaging with machine learning, genetic and environmental perturbations.
Thus far, her research provided new perspectives to key facets of tumor biology, encompassing metabolism, genetics, and immunology. As a postdoctoral fellow at the Broad Institute of MIT and Harvard, she identified regulators of T cell exclusion and dysfunction with Levi Garraway and Aviv Regev. She holds a B.Sc. in Computer Science and Biology and obtained her PhD in 2016 from Tel Aviv University, where she worked with Eytan Ruppin and developed new ways to interrogate cancer metabolism and genetics.
This fall Livnat joined Stanford Genetics to establish a multidisciplinary lab that will harness machine learning in combination with clinical data and extensive functional testing to dissect and target immune dysregulation in cancer, aiming to leverage the versatile, interconnected, and non-linear function of genes, cells, and tissues for disease detection, prevention, and treatment.
Her research has been generously supported by the Schmidt Family Foundation, Rothschild Foundation, the Cancer Research Institute (CRI), the Burroughs Wellcome Fund (BWF), and Chan Zuckerberg Biohub initiative.

Jin Billy Li
Associate Professor of Genetics
Current Research and Scholarly InterestsThe Li Lab is primarily interested in RNA editing mediated by ADAR enzymes. We co-discovered that the major function of RNA editing is to label endogenous dsRNAs as "self" to avoid being recognized as "non-self" by MDA5, a host innate immune dsRNA sensor, leading us to pursue therapeutic applications in cancer, autoimmune diseases, and viral infection. The other major direction of the lab is to develop technologies to harness endogenous ADAR enzymes for site-specific transcriptome engineering.

Professor of Epidemiology and Population Health, of Biomedical Data Science and, by courtesy, of Genetics
BioDr. Witte joined the Stanford community in July 2021. In addition to serving as Vice Chair and professor in the Department of Epidemiology & Population Health, and as a professor of Biomedical Data Science and, by courtesy, of Genetics, he will also serve as a member of the Stanford Cancer Institute.
Dr. Witte is an internationally recognized expert in genetic epidemiology. His scholarly contributions include deciphering the genetic and environmental basis of prostate cancer and developing widely used methods for the genetic epidemiologic study of disease. His prostate cancer work has used comprehensive genome-wide studies of germline genetics, transcriptomics, and somatic genomics to successfully detect novel variants underlying the risk and aggressiveness of this common disease. A key aspect of this work has been distinguishing genetic factors that may drive increased prostate cancer risk and mortality among African American men. Providing an avenue to determine which men are more likely to be diagnosed with clinically relevant prostate cancer and require additional screening or specific treatment can help reduce disparities in disease prevalence and outcomes across populations. Dr. Witte has also developed novel hierarchical and polygenic risk score modeling for undertaking genetic epidemiology studies. These advances significantly improve our ability to detect disease-causing genes and to translate genetic epidemiologic findings into medical practice.
Dr. Witte has received the Leadership Award from the International Genetic Epidemiology Society (highest award), and the Stephen B. Hulley Award for Excellence in Teaching. His extensive teaching portfolio includes a series of courses in genetic and molecular epidemiology. He has mentored over 50 graduate students and postdoctoral fellows, serves on the executive committees of multiple graduate programs, and has directed a National Institutes of Health funded post-doctoral training program in genetic epidemiology for over 20 years. Recently appointed to the National Cancer Institute Board of Scientific Counselors, Dr. Witte has been continuously supported by the National Institutes of Health.
