Dr. Julius mentors Dr. William Arnold joint with Dr. Yifan Cheng, as well as Dr. Eric Figueroa.


Natalia Jura, PhD, Cardiovascular Research Institute (CVRI). The Jura Lab, currently focuses on understanding how membrane-associated kinases, such as receptor tyrosine kinases, assemble into functional complexes and interface with the plasma membrane.

Targeted, region specific or random substitutions are introduced recombinantly to create variants that provide insight into the structure and activity of the target protein. Dr. Craik mentored Alegra Eroy-Reveles.

Grae Davis, PhD, Department of Biochemistry and Biophysics. There are two major research objectives in Davis Lab. They are interested in understanding at a molecular level how individual cells, neurons or muscle, achieve stable levels of activity during development and throughout life.

Work in McMahon laboratory focuses on the role of RAS-activated signal transduction pathways in the aberrant physiology of melanoma, pancreas and lung cancer using in vivo mouse model systems and in vitro cell culture based systems. The RAS-family of GTP binding proteins transmit signals into the interior of the cell via activation of a number of cytosolic signal transduction pathways. Prominent among these is the RAF-MEK-ERK MAP kinase and the PI3'-kinase-PDK-AKT signaling pathways. Components of both of these pathways are linked to the initiation and progression of human cancer both by their association with human RAS oncogenes and by evidence of somatic mutations in BRAF, PIK3CA, AKT and PTEN that occur in a wide range of human malignancies. Dr. McMahon mentored Jillian Silva.

Melanie Ott, MD, PhD, Department of Medicine, UCSF, and Senior Investigator, Gladstone Institute of Virology and Immunology. Research in the Ott lab focuses on two pathogens—the human immunodeficiency virus (HIV-1) and the hepatitis C virus (HCV)—and how these viruses interact with the cells of a host. More specifically, her lab studies the molecular mechanisms by which HIV infects and replicates in CD4 T cells, wreaking havoc on a segment of the body’s immune system. In HCV research, they are examining ways in which HCV viral particles assemble within liver cells—in an attempt to understand the interactions between viral proteins, fat metabolism and mitochondria in these infected cells. Dr. Ott mentored Olivia Sims.

The lab is looking at two key questions: First, how do cells sense temperature and make a developmental switch from the soil to the host program. And second, how does H. capsulatum, which is thought to be the most prevalent cause of fungal respiratory infections in the world, defy the innate immune response to take up residence in immunocompetent hosts? Dr. Sil mentored Chris Villalta.

Jeroen Roose, PhD, Department of Anatomy. The Roose lab studies how different Ras signals drive normal developmental processes of various cell types and organ systems and how (and why) perturbations of Ras-kinase signals cause human disease. Dr. Roose mentors Dr. Saikat Banerjee.


Dean Sheppard, MD, Department of Medicine, Lung Biology Center. Research in the Sheppard lab focuses on the molecular mechanisms underlying pulmonary (and other organ) fibrosis, asthma and acute lung injury. One aim of the research is to identify new therapeutic targets to ultimately improve the treatment of each of these common diseases. The work begins with basic investigation of how cells use members of the integrin family to detect, modify and respond to spatially restricted extracellular clues and how these responses contribute to the development of common lung diseases. The lab has identified important roles for these integrins in models of each common lung disease and key steps upstream and downstream of the integrins that provide potential therapeutic targets. Dr. Sheppard mentored Daud Cole.


Elliott Sherr, MD, PhD, Department of Neurology. Dr. Sherr and his collaborators at UCSF are studying the genetic causes of disorders of cognition and epilepsy, as well as the brain malformations associated with these disorders. Their focus is on polymicrogyria (PMG), Dandy-Walker malformation (DWM), and disorders of brain development that affect the corpus callosum (ACC/DCC).  They are studying the clinical features of these disorders to better understand the problems faced by individuals with these disorders. The goal of their research is to use a better understanding of the underlying genetic causes as a foundation to develop better treatments for these groups of patients. Dr. Sherr mentored Dorothy Jones-Davis.

Jack Taunton, PhD, Department of Cellular and Molecular Pharmacology, and HHMI Investigator. Research in the Taunton laboratory follows two intersecting trajectories: 1. a cell biology trajectory, in which they pursue a biochemical dissection of the signals that control actin assembly and force generation on the surface of cellular membranes; and 2. a chemistry trajectory, in which they synthesize small molecule tools to perturb and thereby illuminate cellular functions. They have used a structural bioinformatics approach to design ultra-specific protein kinase inhibitors. In addition, they have synthesized cotransin, a macrocyclic depsipeptide with potent anti-inflammatory activity. Biochemical and cell biological experiments have revealed its molecular target and mechanism of action. Dr. Taunton mentored Yazmin Carrasco.


Thea Tlsty, PhD, Department of Pathology. Dr. Tlsty's lab is studying the epigenetic and genetic alterations that confer genomic instability and fuel cancer initiation and progression. Recently the lab identified a variant subpopulation of human mammary epithelial cells (vHMEC) that express properties of premalignant lesions without any exposure of the cells to carcinogens. These variant cells exist in vivo in disease-free women. We have also demonstrated that stromal changes extend beyond a supportive role and play key functional roles in facilitating tumorigenesis. They are studying the ability of carcinoma-associated fibroblasts from human tissues to facilitate the transition to tumorigenicity in an otherwise non-tumorigenic cell population. Dr. Tlsty was mentor to past scholars Luis Estevez-Salmeron and Dr. Carlos Rodríguez.


Erik Ullian, PhD, Department of Opthalmology and Physiology. The Ullian laboratory is interested in the interactions between neurons and glia that are required for the proper development and function of the nervous system. To study these interactions they use a variety of techniques including purification of neurons and glia for cell culture, patch clamp recording from neurons both in culture and in slices, and gene chip and molecular techniques to look at genes and proteins that are regulated by neurons and glia. Using these techniques we have begun to identify both extrinsic signals produced by glial cells and intrinsic signals produced by neurons that regulate synapse number and function. Dr. Ullian mentored Tigwa Davis.

Valerie Weaver, PhD, UCSF Institute for Regeneration Medicine. In the Weaver lab, research focuses on several areas: (1) The role of physical force in human embryonic stem cell fate.

Researchers are currently using a combination of mouse genetic, physiologic and real-time imaging approaches to address the following questions: 1. What are the leptin and insulin target neurons in the hypothalamus, and what are the functions of these neurons in energy balance and glucose homeostasis? 2. What are the intracellular signaling mechanisms utilized by leptin in hypothalamic neurons? 3. What are the mechanisms of hypothalamic leptin and insulin resistance? Dr. Xu mentored Jamila Newton.
