Research Focus

My research focuses on understanding how ion channel signaling steers physiological and pathophysiological processes within and between cells. My research is focused on identifying the molecular components that regulate the spatial and temporal dynamics of calcium signals between the plasma membrane and organelles, and the resulting physiological consequences (e.g. regulation of transcription, reprograming the cell fate including cell deaths). One of my main areas of research is to understand these processes and their contribution to the malignant progression of Neuroblastoma and also to the development of multi-drug resistance in Neuroblastoma. Another area of research that I am interested in investigates the dynamic signaling cascades that are induced by pathogens and pathochemical stimuli in the cells of the innate immune system. Recently, I have been working on the pathways that are shared among the two fields, pediatric oncology and innate immunology, and thereby study the interplay of innate immune cells in the tumor microenvironment.

The laboratory uses a combination of high-content imaging, genomic analysis, as well as molecular, biochemical & biophysical techniques.
