Rodrigo Pacheco, PhD, studied biochemistry at the Pontifical Catholic University of Chile from 1995 to 2001. From 2001 to 2006, he worked toward his PhD at the University of Barcelona, Spain, where he studied the role of neurotransmitters -- chemical means of communication between brain cells -- as modulators of immune cell function. Later, he returned to the Pontifical Catholic University of Chile for his postdoctoral training to continue his studies of the immune system from 2006 to 2008. Since 2009, Dr. Pacheco has been leading the Laboratory of Neuroimmunology of the Science for Life Foundation (Fundación Ciencia & Vida), a Chilean nonprofit that performs basic and applied biomedical research. Dr. Pacheco's team has been studying how neurotransmitter dopamine regulates immunity in inflammatory disorders, including Parkinson's disease (PD). His team has published several scientific articles and received funding to study why and how dopamine controls inflammation.
