Brook Nunn is the director of the Environmental Proteomics Center at the University of Washington and is also on the Steering Committee for the NASA Network for Life Detection (NFOLD) Research Coordination Network. She has a wide range or specialties in the life sciences and in chemistry. While her training is in analytical chemistry, she has focused her recent research on using and developing state-of-the-art tandem mass spectrometry technology to analyze and decipher how organisms or communities of organisms, such as a microbiome, adapt to a changing environment. She collaborates with a range of researchers allowing her to explore unique ecosystems such as coral, hydrothermal vents, the open ocean, and microbiome. She recently was given the honor of being on the NASA steering committee to help decide how to detect life on other planetary bodies. Her area of research focusses on peptide and amino acid based life forms. She has expertise in crime scene investigations and forensic chemistry. She has developed a curriculum that teaches students how to critically think and use forensic chemistry to provide court-accepted facts to solve crimes.
