Biography

With more than 25 years at Kaiser Permanente Washington Health Research Institute (KPWHRI), Laura Ichikawa, MS, is known for her analytical skills, attention to detail regarding study design and data management, and expertise in data visualization. Her experience includes observational studies, randomized controlled trials, case-control studies, and multisite analyses.

Ms. Ichikawa is primarily focused on breast cancer and women’s health. She is involved in two large, multisite National Cancer Institute-funded projects: the Statistical Coordinating Center for the Breast Cancer Surveillance Consortium (BCSC) and a colorectal research site for Population-based Research to Optimize the Screening Process (PROSPR). Much of her work with the BCSC has been evaluating mammography performance and use of other imaging modalities such as MRI, or magnetic resonance imaging, especially after a breast cancer diagnosis. Ms. Ichikawa also participated in collaborative research through the Cancer Research Network, including a widely publicized 2004 study that linked not having screening mammograms to late-stage breast cancer. More recently, this work examined the association of chemotherapy use with peripheral neuropathy. Ms. Ichikawa is excited to continue her work in breast cancer research, including in screening, treatment, surveillance, and survival.

Ms. Ichikawa's research with retired KPWHRI Senior Investigator Delia Scholes, PhD, includes studies examining bone loss associated with the injectable hormonal contraceptive Depo-Provera in 2002 and 2005 and oral contraceptives in 2011. She continues to work in areas of women’s health and contraceptive methods.

Ms. Ichikawa is a member of the American Statistical Association and its Puget Sound chapter.
