I was born in India and after completing MSc, moved to Germany where I received a PhD in Physiology at the Medical Faculty of the University of Saarland under the mentorship of Prof Dieter Bruns where I worked on SNARE-mediated fusion of vesicles with the plasma membrane.
I joined in the Department of Reconstructive Neurobiology, University of Bonn, Germany as a postdoctoral fellow in May 2008 where I differentiated neurons and glia from human induced pluripotent stem cells (hiPSCs) and set up and managed electrophysiology and functional imaging rigs and implemented in vitro functional assays using hiPSC-derived neurons and glia.
In October 2018 I moved to Dublin, Ireland and currently working as a postdoctoral researcher at RCSI in Engel group.
One of my current projects is aimed at understanding the role of human P2X7 receptors in normal and epilepsy-affected primary human neurons and glia. I am also interested in the differentiation of neurons and glia from human iPSCs and assessing the phenotypic alterations in neurons and glia differentiated from normal and epilepsy-affected individuals using electrophysiology, imaging and molecular biology.
