Heike Rebholz is currently working as a research associate in the laboratory of Professor Eitan Friedman at the Sophie Davis School  of Biomedical  Education, City College New York.  She received her Master’s degree in biochemistry from the Freie Universitaet Berlin, Germany. After a few years working as a science journalist for German public television, WDR, and for the BBC in London, she earned a PhD in biochemistry at University College in London. Her work focused on signaling pathways involved in cellular growth and division. Dr. Rebholz is interested in dopamine signaling, in particular in trying to define the molecular mechanisms by which modulations and adaptations occur in response to the lack of dopamine, as is the case in Parkinson’ s disease. Of particular importance in this respect is the dopamine 1 receptor pathway which appears to compensate the lack of dopamine by becoming hyper-responsive. Defining the molecules that underlie these physiological and pathological changes is the major goal of her work. Dr. Rebholz has received scholarships from the Carl-Duisberg-Stiftung, Glaxo Smith Kline as well as the Women and Science fellowship of Rockefeller University.
