Dr. Marikki K. Laiho is a Professor of Radiation Oncology and Molecular Radiation Sciences and Oncology at the Johns Hopkins University School of Medicine. Her laboratory has made several important findings on the regulation of p53 tumor suppressor protein in DNA damage and applied these to discovery screens and development of cancer therapeutic molecules.
Dr. Laiho serves as the Willard and Lillian Hackerman Professor of Radiation Oncology and director of the Division of Molecular Radiation Sciences. She co-directs the Cancer Chemical and Structural Biology Program and the Experimental Irradiators Core at the Johns Hopkins University Sidney Kimmel Cancer Center.
She received her bachelor of medicine, licentiate of medicine (M.D.), and Ph.D. degrees at the University of Helsinki. She performed a postdoctoral fellowship in biochemistry at the University of Massachusetts Medical Center and Sloan-Kettering Institute. Dr. Laiho joined the Johns Hopkins faculty in 2007.
Prior to joining Johns Hopkins, Dr. Laiho was a research associate in the Cell Biology and Genetics Program at Memorial Sloan-Kettering Cancer Center. She was also Director of the Molecular Cancer Biology Program at the University of Helsinki.
Her research interests include cancer biology and DNA damage biology.
Dr. Laiho serves on the School of Medicine Research Council at Johns Hopkins and several other institutional committees. Her work has been recognized by national and international awards, including the 2015 Harrington Scholar-Innovator Award. She has published over 100 peer-reviewed articles on cancer biology and the relevance and implications of cellular DNA damage response in cancer. Dr. Laiho holds a part-time position as Professor of Pharmaceutical Cell and Molecular Biology at the University of Helsinki, Finland.
