Tessa Fisher

Education: 

• Ph.D. in Geological Sciences, ASU (2023)
• M.S. in Environmental Science, Washington State University (2013)
• B.A. in Astronomy, University of Virginia (2010)
• B.A. in Biology, University of Virginia (2010)

Research Interests: 

I'm interested in applying ecology and complex systems science to astrobiology and search for life beyond Earth, with a specific focus on chemical reaction network topology as a biosignature for exoplanets
