Adam J. Krieg, Ph.D.

  • Assistant Professor of Obstetrics and Gynecology, School of Medicine
  • Adjunct Assistant Professor, Oregon National Primate Research Center


Dr. Adam Krieg is an Assistant Professor of Obstetrics and Gynecology in the division of Gynecologic Oncology. He holds an adjunct appointment with the Oregon National Primate Research Center in the Division of Reproductive and Developmental Sciences.

Dr. Krieg’s research team studies the role of reduced tissue oxygen (hypoxia) as a factor in tumor progression and normal physiological processes. Dr. Krieg is investigating how various hypoxia-regulated genes contribute to therapeutic response and resistance in gynecological cancers, especially high-grade serous ovarian carcinoma, the most common and deadly of ovarian cancers. Many hypoxia-regulated genes, such as the class of epigenetic regulators called histone demethylases, are also highly expressed in normal reproductive tissues and may contribute to human fertility. To that end, Dr. Krieg is also investigating the role of oxygen, hypoxia-regulated genes, and histone demethylases in influencing normal ovarian processes and infertility.

Dr. Krieg received his Ph.D. in Biochemistry from the University of Illinois, Urbana-Champaign in 2003. As a postdoctoral fellow in the department of Radiation Oncology at Stanford University, he conducted research in hypoxic gene expression mechanisms. In 2010, he continued his studies as an assistant professor of OB/GYN at the University of Kansas Medical Center. He joined the faculty of Obstetrics and Gynecology at OHSU as an assistant professor in 2016.
