Siavash Vaziri is the scientific program manager for the translational component of the Stimulating Peripheral Activity to Relieve Conditions (SPARC) program, an NIH Common Fund initiative aimed at catalyzing the development of more effective and safer device-based neuromodulation therapies. He works with NCATS’ Associate Director for Special Initiatives Danilo A. Tagle, Ph.D., M.S., to help establish partnerships with device companies by facilitating academic-industry collaborations to develop new interventions or enhance existing therapies. Vaziri also provides programmatic management of SPARC translational awards that span both preclinical studies focused on generating safety and efficacy evidence in animal models and early-stage clinical studies that explore the therapeutic potential of neuromodulation in a wide range of conditions (e.g., gastroparesis, atrial fibrillation and incontinence).

Before joining NCATS, Vaziri was a postdoctoral fellow at Johns Hopkins University’s Zanvyl Krieger Mind/Brain Institute, where he conducted research on the neurophysiological mechanisms of cortical visual processing. He obtained a master’s degree and a doctorate in biomedical engineering from Johns Hopkins University.

Research Topics

Vaziri’s research interests cover systems neuroscience and device-based neurotherapeutics.
