Two new Research Fellows join NUS group

Ee-Soo Lee obtained a PhD from the University of Groningen, The Netherlands, under the direction of Prof. Martin Harmsen. Her doctoral studies were based on investigations of the interplay between TGF-β and fluid shear stress in regulation of endothelial cell phenotype and functions, in the context of oxidative stress and cellular senescence. Ee-Soo is joining our nascent metabolism team to focus on studies at at understanding the signaling mechanisms by which teh action receptor ALK7 regulates catecholamine sensitivity in adipocytes.

Chang Liu defended her thesis at the University of Sydney, Australia, under the direction of Prof. Jürgen Götz. Her doctoral studies were aimed towards addressing  the distribution and physiological function of tau isoforms using tau isoform-specific monoclonal antibodies. Liu is joining our NUS group to lead a new line of research aimed towards the elucidation of the roles of neurotrophin signaling in cerebrovascular disease, focusing on their actions on cellular elements of the brain microvasculature under normal conditions and following cerebrovascular damage and AD-related neurodegeneration.

New Senior Research Fellow joins NUS group to launch metabolism programme

Raj Kamal Srivastava obtained his PhD in 2008 at the Department of Zoology, Faculty of Science in Banaras Hindu University, Varanasi, India. He did postdoctoral studies at the Institute for Physiological Chemistry and Pathobiochemistry, Johannes Gutenberg University of Mainz, Germany. His studied the role of central and peripheral CB1 receptor in obesity and behavioral disorder using transgenic mouse lines deleted for CB1 receptor in adrenergic and noradrenergic neurons, CamK2a expressing neurons, and adipocytes. CB1 receptor deletion from adipocytes revealed a significant role of the brain-sensory-adipocyte axis in obesity. The data highlight the role of CB1 receptor in sympathetic activity, food intake and stress induced obesity. At the NUS lab, Raj will lead studies on the roles of activin receptors ALK4 and ALK7 in adipogeneiss, adipose tissue homeostasis and obesity.
