Lillie Fund.
Gregg G. Gundersen, Ph.D. is a Professor in the Departments of Anatomy and Cell Biology and Pathology at Columbia University, New York, New York. The title of his research project is “The role of microtubule capture in cytokinesis.” He will use sea urchin eggs for these studies because of the ease of triggering synchronous cell division, of introducing molecules into eggs, and of imaging cellular events by microscopy. These studies will shed light on a basic process important to all cells and have implications for cancer where abnormal cell division can contribute to chromosome instability. Dr. Gundersen is funded by an award from the Universal Imaging Corporation.
Yosef Gruenbaum, Ph.D., is Head of the Department of Genetics at the Institute of Life Sciences at The Hebrew University of Jerusalem, Jerusalem, Israel. His research project is titled “Molecular and functional dissection of the nuclear lamina in the surf clam.” The nuclear envelope is a selective barrier between the nucleus and the cytoplasm composed of outer and inner nuclear membranes, nuclear lamina, and nuclear pores. It is involved in nuclear organization, cell cycle regulation, nuclear migration, transcriptional repression, cell differentiation and apoptosis. Mutations of the lamina give rise to a range of inherited diseases. Dr. Gruenbaum is here this summer to produce an EST (Expressed Sequence Tags) database as part of the Clam Mini-Genome Project. Dr. Gruenbaum is funded by the Frank R. Lillie Fund, the Herbert W. Rand Fellowship, the Elisabet Samuelsson Director’s Discretionary Fund, and the William T. Golden Fund.

Nevin Alan Lambert, Ph.D. is an Associate Professor in the Department of Pharmacology and Toxicology at the Medical College of Georgia, Augusta, Georgia. The title of his research project is “The role of RGS proteins in regulation of slow synaptic transmission in the CNS.” Dr. Lambert studies the mechanisms of slow synaptic transmission in the central nervous system. He is funded by the MBL Associates and The Stephen W. Kuffler Fellowship Fund.
Matthew E. Larkum, Ph.D. is a Junior Professor in the Department of Physiology at the University of Bern, Switzerland. The title of his research project is “Characterization of the active dendritic properties of the pyramidal cells of turtle cortex.” The turtle cortex has many features in common with the human cortex but is a much simpler system. The most important principles of cortical function have been conserved across the eons because the same cells and principles of architecture can be found in brains from turtles to people. He injects fluorescent dyes into pyramidal neurons to observe and measure functionally relevant intradendritic interactions and their role in cortical information processing. He will use a sensitive high-speed video camera attached to a microscope to quantify calcium changes in the dendrites that affect synaptic plasticity and other mechanisms in the cortex. Dr. Larkum is funded by The Stephen W. Kuffler Fellowship Fund, the Baxter Postdoctoral Fellowship Fund, the M.G.F. Fuortes Memorial Fellowship Fund, and the MBL Associates.
Roland Lill, Ph.D. is a Professor of Cell Biology at the Institute of Cell Biology, Philipps-Universität Marburg, Germany. The title of his research project is “Studies on mitochondrial iron metabolism in yeast and mammals.” Dr. Lill is interested in how iron is metabolized in mitochondria. Defects in iron metabolism are associated with anemia, myelodysplastic syndrome, and Parkinson’s Disease. Dr. Lill received the Leibniz Award in 2002—the most prestigious prize awarded a scientist in Germany. He is funded by the Herbert W. Rand Fellowship.
Christopher Lowe, Ph.D. is a postdoctoral fellow in Dr. John Gerhart’s lab at the Department of Molecular and Cellular Biology, University of California, Berkeley. The title of his research is “Early deuterostome evolution and the origin of chordates: Insights from hemicoradate development.” Dr. Lowe works on the characterization of the development of a direct-developing enteropneust species of hemichordate, Saccoglossus kowalevskii. His goal is to compare the role of conserved developmental regulatory genes during the development of this species and to compare these genes to their orthologues in chordates. Dr. Lowe is funded by The Laura and Arthur Colwin Endowed Summer Research Fellowship.
Issei Mabuchi, Ph.D. is a Professor in the Division of Biology, Department of Life Sciences, Graduate School of Arts and Sciences at the University of Tokyo, Tokyo, Japan. The title of his research project is “Mechanism of determination of the cleavage plane in sea urchin eggs.” Animal cells undergo cytokinesis by virtue of contraction of the contractile ring formed in the cell cortex at the division plane. The contractile ring contains myosin and actin filaments, which are considered to assemble at the division site by signaling pathway(s) that are geometrically controlled by mitotic apparatus. He will investigate how the cleavage plane is determined in animal cells using sea urchin eggs and a centrifuge microscope. Dr. Mabuchi is funded by the Robert Day Allen Fellowship Fund.
Yair Manor, Ph.D. is an Associate Professor in the Life Sciences Department at Ben-Gurion University, Beer-Sheva, Israel. The title of his research project is “Neuromodulation of neuronal networks that produce rhythmic activity.” Neuromodulation affects both intrinsic properties of neurons, and the dynamics of synapses that connect them. Dr. Manor will study the influence of dose-dependent neuromodulation on the pyloric rhythm in the stomatogastric nervous system in crustaceans, via the combined effects on intrinsic properties and synaptic strength and dynamics. Insights obtained from his studies in a small neuronal network will apply to larger vertebrate circuits. Dr. Manor is funded by The Gruss Lipper Foundation.
Christian Tschudi, Ph.D. is an Associate Professor in the Department of Epidemiology and Public Health and the Department of Internal Medicine at Yale University School of Medicine, New Haven, Connecticut. The title of his research project is “Do gene silencing pathways operate in Giardia lamblia?” Gene silencing pathways that function as defense mechanisms against nucleic acid invaders, such as viruses and mobile elements, are present in all eukaryotic organisms and can be thought of as adaptive immune responses at the genome level. Dr. Tschudi is studying RNA interference or RNAi in Trypanosoma brucei, the causative agent of African sleeping sickness. His focus will be to test whether RNAi or RNAi-related mechanisms exist in Giardia lamblia through a combination of molecular and bioinformatics approaches. Dr. Tschudi is funded by the Baxter Postdoctoral Fellowship Fund, The Erik B. Fries Endowed Fellowship, The John O. Crane Fellowship Fund, and the H. Burr Steinbach Memorial Fellowship Fund.
Elisabetta Ullu, Ph.D. is a Professor of Internal Medicine and Cell Biology at Yale University School of Medicine, New Haven, Connecticut. The title of her research project is “The role of gene silencing pathways in trypanosome biology.” Her research focuses on RNA interference or RNAi in Trypanosoma brucei, the causative agent of African sleeping sickness. The interest in T. brucei as a model system to study RNAi stems primarily from its evolutionary position and its biology. Her studies should elucidate whether RNA silencing targets different sets of genes during the life cycle of this organism. Dr. Ullu is funded by the Baxter Postdoctoral Fellowship Fund, The Erik B. Fries Endowed Fellowship, The John O. Crane Fellowship Fund, The Charles R. Crane Fellowship Fund, the H. Burr Steinbach Memorial Fellowship Fund, and the James A. and Faith Miller Fellowship Fund.
Herman Wolosker, M.D., Ph.D. is a Senior Lecturer in the Department of Biochemistry at the Technion-Israel Institute of Technology, Haifa, Israel. The title of his research project is “Neurobiology of D-amino acids.” D-amino acids are present in bacteria and invertebrates, but recently were identified in mammalian brain. Dr. Wolosker will study the neurobiology of D-serine and D-aspartate in primary cultures of mammalian neurons and in tissues of the squid Loligo pealei and other marine invertebrates. These studies may shed light on schizophrenia and stroke. Dr. Wolosker is funded by The Gruss Lipper Foundation.
Dejan P. Zecevic, Ph.D. is a Research Scientist in the Department of Cellular and Molecular Physiology at Yale University School of Medicine, New Haven, CT. The title of his research project is “Signal integration in dendrites of individual vertebrate neurons.” Dr. Zecevic investigates information processing in single neurons by monitoring the activity in different parts of the same cell simultaneously. The information obtained about how normal nerve cells function may help investigators understand mental disorders in humans. Dr. Zecevic is funded by the Herbert W. Rand Fellowship, The Stephen W. Kuffler Fellowship Fund, and the H. Keffer Hartline Fellowship Fund.
