Irina Leaf
Scientist I


Irina has a broad background in immunology and developmental & stem cell biology.
At the University of Minnesota, Irina studied the role of Lim1 in head formation, as well as kidney and heart development in the Bill Shawlott lab. In 2003, Irina moved to Seattle to work on understanding the renewal/differentiation decision in germ stem cells in the Bob Braun lab at the University of Washington. She later joined the Alan Aderem lab (Institute for Systems Biology, Seattle BioMed) in 2007, focusing on the mechanisms of inflammasome activation in immune cells.
Irina has a strong interest in utilizing integrative approaches to understand the factors and mechanisms that regulate the inflammatory response and applying this knowledge to the development of novel therapies.

In her spare time, Irina enjoys learning new things, meeting new people, traveling, spending time with her family (including her dog, Cowboy), running, and playing tennis.
