Channing

Channing Paller ’97 

Channing is a translational researcher and associate professor of oncology at Johns Hopkins where she treats patients and focuses her research on developing more effective and less toxic therapies for prostate cancer and other solid tumors. To translate laboratory discoveries into new treatments, she developed a portfolio of investigator-initiated clinical studies involving immunotherapy, precision therapy, and natural products. She has published more than 60 articles and book chapters and was recently named associate director of oncology for the Johns Hopkins Clinical Research Network.

Channing has long had an interest in determining whether dietary supplements, vitamins, and other natural products, on which Americans spend more than $14 billion dollars each year, are helpful or harmful for cancer patients. Her studies in this and other areas have earned her honors throughout her career including the Young Investigator Award from the American Society of Clinical Oncology, the ECOG Paul Carbone Award, and a multi-year clinical research training grant from NIH.  She is currently the national principal investigator for a randomized placebo-controlled phase III clinical trial, accruing patients at 12 cancer centers around the country, that seeks to determine whether popular antioxidants delay cancer growth in the 25% of cancer patients who carry a specific germline genetic profile. 

Channing recognizes how much her career has been shaped and enhanced by excellent mentors at Sidwell and all through her undergraduate years and medical training. To “pay it forward” she mentors trainees from the high school level through junior faculty at Johns Hopkins.

While she was a student at Sidwell, and through her college years at Bowdoin, Channing interned at the National Institutes of Health. During her medical studies at Harvard, she spent time at the Weizmann Institute in Israel’s Department of Biological Regulation, Massachusetts General Hospital’s Endocrine Unit, and McCord Hospital in South Africa, where she participated in the Harvard AIDS project. During her oncology fellowship at Johns Hopkins, Channing spent time at both the US Food and Drug Administration and the National Cancer Institute’s Cancer Therapy Evaluation Program.

Channing and her husband, Brian Toll, live in Chevy Chase, Maryland with their sons, Alex and Teddy.
