Dr. Berndt is currently involved in a large pooling project of genome-wide scans to examine genetic variants associated with anthropometric traits, such as obesity and height. Other research interests include analyzing claims-based data and exploring dietary risk factors for cancer.

Dr. Berndt is involved in several consortium efforts, including the Breast and Prostate Cancer Cohort Consortium (BPC3), the Genetic Investigation of Anthropometric Traits (GIANT) Consortium, and the International Lymphoma Epidemiology Consortium (InterLymph). She is also a member of the International Genetic Epidemiology Society, the Society for Epidemiologic Research, and the American Pharmaceutical Association.

Building on her background in nutrition, her Ph.D. dissertation at the University of Washington furthered her interests through evaluating the interplay between nutrition and genetics in relation to cancer risk: “Genetic variation in calcium and vitamin D related genes and colon cancer”. Other research she conducted while at the Fred Hutchinson Cancer Research Center included conducting a review of meta-analyses and pooled analyses of genetic polymorphisms and cancer risk, and investigating the association between dietary factors in a cohort of individuals with Barrett’s esophagus.

Linda joined OEEB as a Sallie Rosen Kaplan post-doctoral fellow. The work she is doing here is with Wong-Ho Chow, Ph.D., and Lee Moore, Ph.D., evaluating both genetic and lifestyle risk factors from two large case-control studies of renal cancer conducted in the U.S. and Europe. In addition, she is involved in studies on upper gastrointestinal cancer (esophageal and gastric) within several consortiums. During her time in OEEB, Dr. Dong has received several awards, including a DCEG Molecular Epidemiology Research Award and an NIH Fellows Award for Research Excellence (FARE).

She has published in the Journal of the American Medical Association (JAMA), Lancet Oncology, International Journal of Behavioral Nutrition and Physical Activity, Nutrition and Cancer, and Cancer Epidemiology Biomarkers and Prevention.
