D. in Biology/Zoology from Cambridge University / Kings College in 1988, before moving on to a postdoctoral fellowship at the University of California at San Francisco. His lab seeks the mechanisms by which microtubules perform a number of morphogenetic processes, such as spindle assembly and membrane traffic, making use of a wide range of genetic, biochemical, cell and molecular approaches in three main model systems: the budding yeast S.cerevisiae, the African clawed toad, Xenopus laevis, and the free-living nematode, Caenorhabditis elegans.








Yuh Nung Jan 
Dr. Yuh Nung Jan is a Professor of Molecular Physiology at the University of California San Francisco, an Investigator of the Howard Hughes Medical Institute, and a member of the National Academy of Sciences. Early in his career he focused on neuronal function, performing some of the key studies on the role of neuropeptides in synaptic transmission and the cloning and functional characterization of voltage-gated ion channels. More recently he has made major contributions to our understanding of the development of the nervous system. He has used Drosophila genetics to identify key molecules controlling neuronal cell fate, to elucidate the cellular mechanisms underlying asymmetric cell division and inheritance, and to discover the molecular processes regulating the pattern of dendritic branching.




David Ish-Horowicz 
David Ish-Horowicz is head of the Cancer Research UK Developmental Genetics Laboratory at the CR-UK Lincoln's Inn Fields Laboratories in London, and studies the molecular mechanisms that regulate patterning of invertebrate and vertebrate embryos. He studied at the MRC Laboratory of Molecular Biology, Cambridge, and researched with Professor Walter Gehring in Basel, Switzerland, before establishing his own research group at the (then) Imperial Cancer Research Fund in London. His earlier work dealt mainly with the molecular genetics of Drosophila segmentation genes, with a particular interest in the pair-rule genes whose striped expression establish metameric (repeated) pattern. During this time, his lab identified the Hairy bHLH protein repressor and demonstrated that Hairy and related repressors act via the Groucho transcriptional corepressor. His group currently studies mechanisms of intracellular RNA localisation in Drosophila, using in vivo assays to characterise the RNA signals and motor machinery that underlie selective RNA transport. He also analyses segmentation in vertebrates, with an emphasis on the molecular oscillator ("segmentation clock") that appears to drive somitogenesis. His lab has identified transcriptional regulatory elements that drive cyclic transcription prior to segmentation, and is studying their regulation in order to understand the molecular basis of the clock. He is a member of the European Molecular Biology Organisation, an Honorary Research Professor of University College London, and a Fellow of the Royal Society.



Hiroshi Hamada 
Hiroshi Hamada received his M.D. from Okayama University, Medical School in 1975, and a Ph.D. from Okayama University, Graduate School in 1979. After 5 year as a post-doc in the NIH, he became an Assistant Professor at Memorial University in Newfoundland, Canada, and started working on the regulation of EC cell differentiation. Since 2002, Hiroshi has been a professor at the Graduate School of Frontier Biosciences, Osaka University. His research interests have focused on the genetic dissection of mouse embryogenesis. In particular, his current interests include 1) early embryonic patterning events such as anteroposterior patterning and left-right patterning, 2) regulation of organogenesis by retinoic acid, and 3) maintenance of pluripotency. His major achievements are 1) establishment of enhancer-trap method with cultured cells, 2) identification of Oct3/4, a transcription factor required for maintaining pluripotency, 3) dissection of genetic pathway for left-right patterning.





Edward M. De Robertis 
Edward M. De Robertis grew up in Montevideo, Uruguay where he received his M.D. degree in 1971. After completing a Ph.D. in Chemistry with H. N. Torres in Argentina, he trained in Xenopus embryology under John B. Gurdon in Cambridge, England. His work in developmental biology has contributed to the realization that antero-posterior and dorso-ventral patterning genes have been conserved throughout animal evolution. His work on Chordin, a secreted antagonist of ventral BMP signals that is regulated by proteolytic cleavage, has provided a new paradigm for intracellular signaling. He joined the UCLA School of Medicine in 1985, where he is the N. Sprague Professor of Biological Chemistry and Investigator of the Howard Hughes Medical Institute. He is a member of the European and Iberoamerican Molecular Biology Organizations, of the American Academy of Arts and Sciences, and of the Latin American Academy of Sciences. Dr. De Robertis serves as President of the International Society of Developmental Biologists (ISDB).



Olivier Pourquie 
Dr. Olivier Pourquie received his PhD from the National Institute for Agronomy in France and his advanced training in Developmental Biology from Nicole Le Douarin at the Institute d'Embryologie du College de France at Nogent sur Marne. He was a group leader at the Developmental Biology Institute of Marseille (France) for six years and in 2002 he relocated his lab to the Stowers Institute for Medical Research in Kansas City (USA).
Pourquie is widely recognized as an international scholar of Vertebrate Developmental Biology. He is known for the discovery of a molecular oscillator, called the Segmentation Clock, involved in the metamerization of the vertebrate body axis. He is a member of the European Molecular Biology Organization and until this year was president of the French Society for Developmental Biology.
Pourquie's research is aimed at understanding the molecular basis of vertebrate body axis segmentation and patterning during Development. His work has relied heavily on the use of the chick embryo as a model system, but it also largely involves mouse genetics.



Elaine Fuchs 
Dr. Elaine Fuchs received her B.A. in Chemistry from the University of Illinois, her PhD in Biochemistry from Princeton University and her advanced training in skin biology from Howard Green at MIT. She was a Professor at the University of Chicago for 20 years, before relocating her laboratory to Rockefeller University in New York City in 2002.
Fuchs is widely recognized as an international scholar of skin biology. She is known for her unconventional use of "reverse genetics" in her research, where she typically begins with a protein and works her way to the underlying basis of a human genetic disorder. She is a member of the National Academy of Sciences (NAS), the Institute of Medicine, and the American Academy of Arts and Sciences. In the past year, she has been the President of the American Society of Cell Biology, the recipient of the Richard Lounsbery Award by the NAS, and elected to the Council of the NAS.
Fuchs' research focuses on understanding the molecular mechanisms underlying development and differentiation of the mammalian skin epidermis and its appendages, and how these processes go awry in various human diseases of the skin, including genetic diseases and skin cancer. She utilizes mammalian stem cell cultures and gene-knockout technology as model systems.

Her research on the development of the visual system focuses on cell fate decisions in the retina and axon guidance.



Hajime Fujisawa 
My scientific interest is focused on cellular and molecular mechanisms that guide axons with a high degree of precision to establish fairly stereotyped neuronal connections. From the end of 1970th to the beginning of 1980th, I performed anatomical studies on amphibian and avian retinotectal projection system. I labeled retinal axons with neuronal tracers, and showed how individual developing and regenerating axons from different parts of the retina recognize discrete regions within the tectum to give raise to a fairly organized retinotopic neuronal connection. I then started the screening of molecules that would be involved in the establishment of the retinotectal projection in Xenopus tadpoles, by hybridoma techniques, and identified two molecules named as neuropilin and plexin. Nowadays, 2 neuropilins and more than 10 plexins have been identified in various animal species and assumed to serve as receptors for semaphorins, a large family of axon guidance molecules with repulsive and attractive nature. Currently, my works are focused on how semaphorins and their receptors regulate axon guidance and neuron network formation in vivo.



Mu-ming Poo 
Mu-ming Poo is currently the Class of 1933 Professor and Head of Division of Neurobiology at University of California, Berkeley. Poo was born in China, received his B.S. degree in physics from Tsinghua University in Taiwan in 1970, and his Ph.D. in biophysics from Johns Hopkins University in 1974. After two years of postdoctoral research at Marine Biological Laboratory, Woods Hole, and Purdue University, he joined the faculty of University of California at Irvine in 1976. Since 1985, he has held faculty appointments at Yale University, Columbia University, and University of California at San Diego before assuming his current position at U.C. Berkeley. His research interests have covered many areas of developmental neurobiology, including axon guidance, synaptogenesis, and synaptic plasticity. In recent years, he has made important contributions in our understanding of signal transduction mechanisms underlying axon guidance and the role of electrical activity and neurotrophic factors in regulating synaptic functions and the assembly of neural circuits. For his work on axon guidance, he was awarded the Ameritec Prize for Paralysis Research in 2001. He is currently a member of the editorial board of Neuron and Journal of Neuroscience.
