Chemist by Training, Explorer by Heart | Q&A with NASA Materials Chemist

ACS CHEMMATTERS MAGAZINE

Yajaira Sierra-Sastre is always looking for new worlds to explore. As a young girl growing up in Puerto Rico, she gazed at stars through a clear night sky. “My first passion was for anything related to astronomy and planets and stars and space,” she says. Sierra-Sastre fell in love with science during childhood, and went on to study chemistry at the University of Puerto Rico, Mayagüez.“I could see chemistry all around me,” Sierra-Sastre says. After graduating, she started on a path to connect her studies with the real world in as many new ways as possible. “I had this desire of just going out on an adventure.”

In the 20 years since, she has used her degree to teach high school chemistry; earn a PhD making nanomaterials for space experiments; help create new types of textiles and batteries; spend months living in a Mars simulation; and oversee the research projects that keep printed money secure.
