Parag Vaishampayan

As a staff scientific I am providing support to a multifunctional, multidisciplinary, biotechnology–based laboratory. My major emphasis is on characterizing the microbial diversity of communities associated with spacecraft outbound from Earth and the clean-room facilities in which they are assembled. I have applied my scientific expertise and bioinformatics knowledge to decipher the microbial ecology of diverse and extreme environmental niches encompassing spacecraft assembly clean rooms, stratospheric air samples, high altitude caves, hydrothermal vents and human gut to name few. I am the main bioinformatician for our group at JPL for the generation and curation of a comprehensive sequence database. A significant advantage of this database is its application to industries and disciplines outside of astrobiology in particular, and NASA in general.
