WHAT DO WE STUDY?
Using protein chemistry to solve biochemical mysteries in the environment
Proteins are the biochemical machines of the cell and can provide a seasoned chemist with a wide range of information on the status or plans of a cell. We use state-of-the-art tandem mass spectrometry technology and bioinformatic tools in order to analyze and decipher protein expression from a variety of samples from the environment. Our focus is the marine environment. Be it particles floating in the ocean, sediments on the ocean floor, phytoplankton adapting to climate change, or bacteria surviving on hydrothermal vent plumes or in Arctic ice channels, we are interested and excited to tackle the project.

2024 NASA Simulated Mission to detect Extant Life on Mars
In November 2024, Prof. Nunn directed the NASA Mission Ideation Factory (MIF) Phase 2 Simulated Mission, a groundbreaking live-action role-playing (LARP) experience designed to simulate two fully developed science payloads for missions to Mars aimed at detecting extant life. This innovative project spanned three months of development and was supported by her exceptionally talented Mars Mission Simulation Team. The team included UW Astrobiology graduate students Pete Wynn (Lead Geologist), Yuk Chun Chan (Lead Atmospheric Chemist), Andrew Shumway (Lead Mars Expert), Megan Gialluca (Lead Python Coder and Communications Expert), and postdoc (now NASA Johnson Space Center Scientist) Ardith Bravenec (Lead Physical Chemist). Additionally, Felisa Wolfe-Simon, a renowned astrobiologist from the Monterey Bay Research Institute known for her expertise in unique metabolisms and adaptations, co-led the experience with Prof. Nunn.... read more here... See our NEWS page!! Emma Timmins Schiffman went to Antarctica to do the first snow metaproteome! Her Blog is excellent.
August 21 2023: Dr. Nunn was invited to speak at National Academy of Sciences panel on Continental Scale Biology- See her talk HERE!

ABOUT THE LAB
Brook Nunn joined Michael MacCoss' lab in the Department of Genome Sciences to run the environmental division in 2015 as a Research Assistant Professor. Historically, the Nunn lab has focused our efforts on proteomic profiling. Proteomic profiling allows the investigator to catalog all the proteins expressed at the time of harvest in an unbiased manner and is a very thorough hypothesis-generating method. This method allows us to figure out how the organism is adapting to a unique environment by globally assaying the organism's response or to find out which protein functional groups are common in preserved organic matter.
Since joining the MacCoss lab group, the focus of the lab has shifted. We now include more targeted and quantitative methods. It is an exciting time to be in the proteomics field!

This lab is a division of the MacCoss lab of Biological Mass Spectrometry at the University of Washington Department of Genome Sciences. It is currently funded independently by Dr. Brook Nunn through the generous grants provided by the National Science Foundation, the National Institute of Health, and NASA.
