A: Katherine Calvin is an American earth scientist, mathematician, and computer scientist. She is known for leadership roles at U.S. research institutions and for serving as NASA Chief Scientist from January 10, 2022, to March 10, 2025. ### Q: What positions has she held? A: Calvin has worked at the Pacific Northwest National Laboratory (from 2008), was affiliated with the Joint Global Change Research Institute, worked at the Energy Information Administration from 2001 to 2003, and held the position of NASA Chief Scientist (2022–2025). ### Q: What is her educational background? A: She was educated at Stanford University and the University of Maryland, Baltimore. ### Q: Does she have published research? A: Yes. Calvin appears in scholarly databases and author identifier systems such as Scopus (author ID 26640190700), Dimensions (author ID 0753113656.07), and ResearchGate (contributions ID 74598652), indicating published research, though specific papers are not listed in the provided material. ## Why They Matter Katherine Calvin’s significance derives from a sustained career at the intersection of earth science, mathematics, and computing, combined with senior leadership appointments in major U.S. research organizations. Her long-term employment at the Pacific Northwest National Laboratory and affiliation with the Joint Global Change Research Institute link her work directly to climate-change research infrastructure in the United States. Serving as NASA Chief Scientist placed her among the agency’s senior scientific appointees during 2022–2025, a role that associates her name with national-level science leadership. Calvin’s presence in major scholarly identifier systems (Scopus, Dimensions, ResearchGate) documents a research record that supports those leadership positions. Without her documented contributions and appointments, the specific combination of scientific, computational, and institutional leadership she provided to those organizations during her tenures would have been undertaken by others; her record remains part of the institutional and scholarly history of contemporary U.S. earth and climate science. ## Notable For - Serving as NASA Chief Scientist from 2022-01-10 to 2025-03-10. - Long-term employment at Pacific Northwest National Laboratory (start year 2008). - Affiliation with the Joint Global Change Research Institute, a U.S. climate change research lab. - Early-career role at the U.S. Energy Information Administration (2001–2003). - Presence in major research author identifier systems (Scopus author ID 26640190700; Dimensions author ID 0753113656.07). ## Body ### Identity and Names - Full name: Katherine Calvin. - Aliases: Kate Calvin; Katherine V.
