Dr. Willis X. Li received his Ph.D. from Columbia University and is currently Professor of Medicine in the Biomedical Sciences Graduate Program at the University of California, San Diego. He is a prolific author and his more recent works include two books for Springer's Methods in Molecular Biology/Protocols series. His investigative interests are JAK/STAT signaling and innate immunity, epigenetic mechanism of tumor suppression and tumorigenesis, and the role of heterochromatin in aging and stem cells.Dr. Louis Silver-Morse received her Ph.D. from the State University of New York at Stony Brook.  She did research in genetics as a postdoctoral fellow in the Department of Biomedical Genetics at the University of Rochester Medical Center.  She has published research articles and reviews in premier scientific journals.  She is currently a freelance writer/editor.
