New postdoc fellow joins KI group to study roles of p75NTR signaling in neuron survival and differentiation

Shounak Baksi obtained his PhD at the University of Calcutta, India, in September 2009. His thesis work focused on studies of alterations in Growth Factor Receptor Protein Binding Protein 2 (Grb2) signaling in Huntington’s disease cell model. His postdoctoral studies in Case Western Reserve University, Cleveland, OH, under the direction of Dr. Neena Singh,  focused on the role of Parkinson’s disease protein alpha synuclein in retinal and brain iron homeostasis.

Carlos Ibanez appointed as Wallenberg Scholar

The Knut and Alice Wallenberg Foundation has today appointed Carlos Ibanez as a Wallenberg Scholar. The award includes a research grant of 15 million Swedish crowns over 5 years. Quote from the Foundation’s website: “The Foundation’s purpose is to support Swedish research and thereby strengthen Sweden as a research nation. Since 2009, we have appointed a total of 46 Wallenberg Scholars. The appointed researchers all belong to the international research forefornt in all areas of science, with an emphasis on medicine and the natural sciences, says Peter Wallenberg Jr., vice chairman of the Knut and Alice Wallenberg Foundation.” Read the text of the announcement (in Swedish) HERE and press release from Karolinska Institute HERE.

Thesis nailing


PhD student Carolyn Marks nailed her thesis at the KI library this week. Tradition obliges, and the golden nail went into the wooden slab one more time.

The event marks the final count-down for her thesis defense, to take place on December 7. Attracted by the prospect of champagne and refreshments, fellow lab mates joined in for the occassion.

Carlos Ibanez starts new laboratory at the Life Sciences Institute of the National University of Singapore

Starting in the Fall of 2012, a new laboratory dedicated to neurotrophic factor research will be established at the Life Sciences Institute (Neurobiology Programme) of the National University of Singapore. The research actitivies of the NUS lab will run in parallel to and complement with those ongoing at the KI lab. The initial focus of the NUS group will be on genetic studies of death receptor signaling and physiology, as well as the identification of novel, mechanism-based receptor inhibitors. Follow developments in the NUS lab at carlosibanezlab.se/NUS.

PhD student Carolyn Marks to defend doctoral thesis in December

PhD student Carolyn Marks is set to defend her thesis, entitled “Regulatory mechanisms in olfactory system assembly and function”, on December 7, 2012. Her external examiner will be Professor Charles Greer from Yale University. Faculty members in the thesis committee will be Professors Ole Kiehn (KI), Jonas Muhr (KI), Tibor Harkany (KI) and Anders Lansner (KTH).
