Space radiobiology

Research Interests

The overall goal of Dr. Vazquez’s current research is to assess the effects of the space environment on neuronal cell functional integrity at the molecular and cellular level. Currently, the team is examining the effects of HZE particle exposure using neural explants, established and primary neural cell lines as a paradigm for space radiation neurotoxicity. The study of the cellular and molecular alterations associated with heavy ion neurotoxicity and how changes in LET and projectile fragmentation modulate the biological response are critical parts of this research.
