Dr. Marcelo Vazquez

Dr. Marcelo Vazquez is an Associate Professor at the Radiation Medicine Department, Loma Linda University, CA. Currently Dr. Vazquez directs several educational programs on radiation biology as well as develops translational research projects related to radiation therapy using protons. He is also an independent consultant in space radiation, space radiobiology and radiation risks. Dr. Vazquez worked for 11 years at the Brookhaven National Laboratory (BNL) supporting the NASA Space Radiation Health Program as a principal investigator, scientific liaison and program manager of the long-term support facility for NASA’s particle accelerator users. Dr. Vazquez created, directed and managed the NASA Space Radiation Summer School at BNL from 2005 to 2006. After his work at BNL, Dr. Vazquez was hired by the National Space Biomedical Research Institute (NSBRI) at Baylor College of Medicine, to serve as the institute’ space radiation liaison to NASA as well as an advisor and senior scientist. He also serve as a project manager for the NSBRI’ sponsored Lunar EVA Dosimetry project as well as the NSBRI’ Center for Acute Radiation Research. Representing NSBRI, Dr. Vazquez was Field Research Participant at the NASA/Mars Institute/Haughton Mars Project station at Devon Island, Canada performing several experiments for NSBRI and NASA. Scientific Interests: assess the effects of the space radiation environment on human health, develop medical countermeasures for deep space exploration, radiation oncology and first responders in case of a radiological accidents as well as the use of particle radiation to treat cancer.

Broadcast 541 (Special Edition)

Dr. Marcelo Vazquez was the special guest for this Space Show program. This program focused on cosmic radiation, how to shield for it to protect astronauts, what it is, what it does, what is the state of the art in handling cosmic radiation, what does the future hold for long term space flight or settlement and much more. Dr. Vazquez answered many listener questions, compared radiation on the Moon with Mars and in deep space as well as LEO. We also talked cosmic radiation versus other types of radiation, the use of radiation for medical treatment, Ozone shielding, etc.
