Scott Keeney


Meiotic recombination

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.

Juergen Knoblich


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.

Zu-Hang Sheng


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.
