Anila Kanchan Madiraju

Research Associate

Anila Kanchan Madiraju earned her Ph.D. in Cellular & Molecular Physiology from Yale University, where she studied the role of redox and mitochondrial energetics in whole body physiology and metabolism. As a part of her thesis work in the lab of Dr. Gerald I. Shulman, she investigated the mechanism of the widely used diabetes drug metformin. Additionally, she discovered signaling mechanisms that integrate ureagenesis and amino acid catabolism with glucose metabolism and energy homeostasis in the liver. In January 2015, she joined the Montminy lab where she currently studies signal transduction pathways involved in adipocyte differentiation, and is continuing her work on amino acid metabolism and ureagenesis. Outside of the lab, Anila is an active member of the Society for Research Fellows at the Salk Institute, and is a community science educator. She was named the 2016 Jonas Salk Fellow.

Research Associate

Jelena Ostojić studied biology at Universities of Trieste in Italy and Paris 7 in France, where she obtained her Bachelor and Master degrees, respectively. She obtained her PhD in September 2013 from the University of Evry Val d’Essonne in France. She worked on the assembly and interactions of OXPHOS complexes in the yeast Saccaharomyces cerevisiae, in the group of Dr. Geneviève Dujardin (Center for Molecular Genetics, Gif sur Yvette, France). Jelena joined the Montminy lab in May 2014 where she is working on the post-translational regulation of CREB activity and its downstream effects, in particular on mitochondrial biogenesis.

Pagkapol (Yhew) Pongsawakul

Research Associate

Pagkapol (Yhew) Pongsawakul is a postdoctoral research associate who joined the lab in September of 2013. He obtained his Ph.D. in Biology from the Division of Biological Sciences at the University of California, San Diego under supervision of Drs. Steve Kay and Marc Montminy. He earned his B.S. in Biology and B.A. in Chemistry from the University of Virginia. At Montminy lab in collaboration with the Kay lab at USC, Yhew is studying the molecular mechanism of Cryptochromes and their mechanism in repressing cAMP signaling.

Dorothea Portius

Research Associate

Dorothea Portius studied Nutritional Science at the Martin-Luther University Halle-Wittenberg in Germany. She performed her Diploma Thesis at the Else-Kröner Fresenius Institute, TU Munich, where she investigated metabolic profiling during adipogenesis in mouse and human. After, she moved to Switzerland and started her PhD in the lab of Prof M.Foti at the University of Geneva, Department for Cell Metabolism and Physiology. Her main interest was to understand the distinct contributions of hepatic insulin and IGF-1 receptor signaling in hepatic metabolic disorders induced with PTEN deletion in mice. In May 2017, Dorothea joined the Montminy lab and started to work on the physiological and transcriptional role of the long-non coding RNA LINC00374 in β-cells.

Tim Sonntag

Research Associate

Tim Sonntag studied biology at the Philipps-University Marburg, Germany. After earning his Diploma in Biology, he moved to the TU Dortmund University and started to work on his thesis in the group of Dr. Henning Mootz. In 2010 he received his Dr. rer. nat. after working in the field of chemical biology with a focus on the application of split inteins, protein domains that self-catalyze their excision from a precursor protein, for protein functional control and segmental isotopic labeling based NMR approaches. In June 2011 he joined the lab of Dr. Steve Kay at UCSD and studied molecular interactions of circadian proteins, in particular mammalian cryptochromes. After joining the Montminy lab in December 2012 he shifted his research focus towards mechanistic studies involving CREB and specific interaction partners.

Sam Van de Velde is a postdoctoral research associate who joined the lab in June 2007. He obtained his Ph.D. in biochemistry from the KU Leuven in Belgium. He previously studied glucose and sucrose induced signaling mechanisms in yeast in the laboratory of Dr. Johan Thevelein. Currently, he is investigating TORC2 function in pancreatic beta cells. He aims to understand the mechanism by which TORC2 regulates glucose homeostasis and beta cell function by using animal models, cultured insulinoma cell lines and his first love, yeast.
