Integrative systems physiology
Johan Auwerx is a professor at the École Polytechnique Fédérale in Lausanne, Switzerland. Dr. Auwerx has been using molecular physiology and systems genetics to understand mitochondrial function and organismal metabolism in health, aging, and disease. Much of his work has focused on understanding how diet, exercise, and hormones control mitochondrial metabolism through changing the expression of genes by altering the activity of transcription factors and their associated cofactors. His work was instrumental for the development of several compounds that are currently used to treat high blood lipid levels, fatty liver, and type 2 diabetes. He was elected as a member of the European Molecular Biology Organization in 2003 and has received many international scientific prizes. Dr. Auwerx received both his MD and PhD in molecular endocrinology at the Katholieke Universiteit in Leuven, Belgium. He was a postdoctoral research fellow in the Departments of Medicine and Genetics of the University of Washington in Seattle. Photo courtesy of the École Polytechnique Fédérale de Lausanne.

Small RNA silencing pathways in genome defense
Julius Brennecke is a senior investigator at the Institute for Molecular Biotechnology of the Austrian Academy of Sciences (IMBA) in Vienna. After studying biology at the University of Heidelberg (Germany) he joined the group of Steve Cohen at the European Molecular Biology Laboratory (EMBL) for his PhD training. There, he became interested in small RNA silencing pathways and studied the biology of microRNAs in Drosophila. For his postdoctoral studies, he moved to Cold Spring Harbor Laboratories and worked with Greg Hannon on the gonad-specific Piwi–piRNA pathway that silences transposable elements in animal germ cells. In 2009, Dr. Brennecke started his independent research group at IMBA, an institute dedicated to basic research in molecular biology. His team studies the ancient arms race between transposons and the host genome in gonads with a focus on Drosophila ovaries. Here, the Piwi–piRNA pathway acts as a small RNA based genome immune system by suppressing the deleterious activity of selfish genetic elements during gametogenesis.

Nika N. Danial
Cellular fuel preferences and metabolic control of cell fate and function
Nika Danial is an associate professor of cell biology at the Dana-Farber Cancer Institute, Harvard Medical School. She obtained her PhD from Columbia University, and subsequently trained with the late Stanley J. Korsmeyer as a postdoctoral fellow at the Dana-Farber Cancer Institute, where she identified a novel role for the BCL-2 family protein BAD in glucose metabolism independent of its apoptotic function. The broad goal of the research in her laboratory is to determine how alternate fuel sources (carbohydrates, fatty acids, and ketone bodies) modulate cellular stress responses. Toward this goal, her group uses contemporary tools of mouse genetics, chemical biology, proteomics, and metabolomics to determine both the molecular mechanisms and biologic consequences of reprogramming cellular fuel preferences. This line of investigation has provided molecular insights into cellular adaptation to nutrient availability, metabolic control of seizure responses, and metabolic heterogeneity in tumors.

Cell division and nuclear biogenesis
Jan Ellenberg heads the Cell Biology and Biophysics Unit at the EMBL in Heidelberg, Germany. Over the past 20 years Dr. Ellenberg has been interested in cell division and nuclear biogenesis, including systems analysis of mitosis, nuclear pore complex assembly, and formation of mitotic chromosomes.

Scott Keeney is a member of the Molecular Biology Program, Memorial Sloan Kettering Cancer Center (MSKCC), and Howard Hughes Medical Institute investigator. He is also a professor in the Louis V. Gerstner Graduate School of Biomedical Sciences (MSKCC) and the Weill Cornell Graduate School of Medical Sciences.

Research in his lab aims to understand the mechanism and regulation of homologous recombination during meiosis. His group studies meiosis principally in mouse and in S. cerevisiae, using molecular genetic, biochemical, genomic, and cytological approaches. As a postdoc, he discovered that Spo11 is the protein that generates the double-strand breaks that initiate meiotic recombination. As an independent researcher, his lab discovered a pathway for endonucleolytic processing of covalent protein-linked double-strand breaks; devised novel strategies for mapping the genome-wide distribution of breaks; demonstrated a mechanism that maintains crossover numbers when double-strand break numbers are decreased (a phenomenon we call crossover homeostasis), and dissected negative feedback pathways that control break numbers.

Stem cells and asymmetric cell division
Juergen Knoblich is a senior scientist and deputy director at IMBA, Vienna. He obtained his PhD from the Max Planck Institute in Tübingen. After a postdoctoral period in the laboratory of Yuh Nung Jan at the University of California, San Francisco, he joined the Institute of Molecular Pathology in 1997 as a junior group leader. In 2004, he moved to IMBA, where he is now senior scientist and deputy director. His laboratory is interested in the biology of neural stem cells. In the fruit fly, they have identified the molecular mechanism that allows neural stem cells to divide asymmetrically and segregate protein determinants into only one daughter cell during mitosis. They have demonstrated that defects in this mechanism lead to brain tumor formation. More recently, they have extended their interest to analyzing mammalian neural progenitors and their contribution to brain development. To analyze those processes in humans, they have established a 3D culture system that recapitulates the early steps of human brain development in cell culture allowing brain pathologies and human-specific developmental events to be studied in unprecedented detail.

Axonal transport of mitochondria, endolysosomes, and synaptic cargoes
Zu-Hang Sheng is a senior investigator and chief of the Synaptic Function Section at the National Institute of Neurological Disorders and Stroke, National Institutes of Health, in Bethesda, MD. He received his PhD in biochemistry from the University of Pennsylvania with Roland Kallen and Robert Barchi. He completed his postdoctoral research with William Catterall at the University of Washington. His laboratory focuses on mechanisms regulating axonal transport that are essential for the maintenance of synaptic function and axonal homeostasis. Using genetic mouse models, his group is addressing several fundamental questions: (1) how mitochondrial transport is regulated to sense changes in synaptic activity, mitochondrial integrity, axon injury, and pathological stress; (2) how neurons coordinate late endocytic transport and autophagy-lysosomal function to maintain cellular homeostasis; and (3) how impaired transport contributes to synaptic dysfunction and axonal pathology in neurodegenerative diseases. These studies have led to the identification of several motor adaptor and anchoring proteins that regulate axonal transport of mitochondria, endolysosomes, and synaptic cargos.
