As a research center embedded within Kaiser Permanente’s large and dynamic health care system, our investigators have a unique opportunity to apply scientific expertise to real-world clinical problems, translate findings into practice, and share what we learn with the broader community.
Dr. Lei Qian is a collaborative biostatistician research scientist and the biostatistician lead in the Division of Epidemiologic Research for the Department of Research & Evaluation. Her methodological research focuses on bias assessment for observational data, propensity score analysis, sequential analysis, self-controlled study design, linear and non-linear trends analysis with applications in vaccine and cardiovascular disease research.
Dr. Qian has extensive research experience ...
Being active can lower your risk of getting seriously ill with COVID, regardless of your race or the chronic conditions you may have, according to research published last year in the American Journal of Preventive Medicine.
The Kaiser Permanente Southern California findings were important, impactful, and influential. As a result, the journal editors chose the research article, “Associations of Physical Inactivity and COVID-19 Outcomes Among Subgroups,” as the American Journal of Preventive Medicine 2023 Article of the Year.
A behavioral and public health scientist, Taynara Formagini, PhD, MSc, is a postdoctoral research fellow in the Department of Research & Evaluation. Her work focuses on preventing cardiovascular and chronic diseases among racial and ethnic minorities and socioeconomically disadvantaged populations through a combination of intervention research and epidemiology. What inspired you to pursue research? I’m ...
Kaiser Permanente research found that breast cancer survivors have a higher risk of developing other cancers if they have other preexisting health conditions, such as high blood pressure and diabetes. “Preexisting health conditions are common in people diagnosed with cancer and what we’ve learned with this study is that comorbidities — experiencing multiple illnesses or ...
Maheen Humayun, PhD, MPH, is an infectious disease epidemiologist and postdoctoral research fellow in the Department of Research & Evaluation. Prior to joining Kaiser Permanente, Dr. Humayun worked as an HIV Cluster Detection and Response Fellow at the Centers for Disease Control and Prevention. In that role, she analyzed national HIV surveillance data to detect rapid ...
About 16% of breast cancer survivors continued to use opioid pain medications after their cancer treatment was complete, a new Kaiser Permanente study showed. The study also found that risk of death was 84% higher among these survivors who continued to use opioids. The study was published in June 2025 in JNCI Cancer Spectrum. “The ...
Growing numbers of patients are diagnosed with cancer between the ages of 15 and 39. These younger cancer patients can have complex health needs after their cancer treatment and should receive health care that includes screening for new cancers, addresses potential issues related to their treatment, and emphasizes general preventive care. Researchers at Kaiser Permanente ...
The latest IMPACT newsletter, which focuses on research from Kaiser Permanente Southern California, is now available! It features 11 stories on our groundbreaking research, links to over a dozen media stories, and a Q&A with a health economics investigator.
Investigators with the Division of Biostatistics Research collaborate closely with scientists from the department’s other scientific divisions, as well as physician researchers at medical centers across Kaiser Permanente Southern California. They provide expertise and guidance on study design, power and sample size calculations, data management, data analysis and interpretation, and statistical methodology.
Investigators from the division have expertise in study design and data analysis for observational studies and clinical trials to address study questions. Their expertise spans standard and modern methods that deal with complex and big data for population and causal inferences as well as disease prediction.
Each division has at least one dedicated collaborative biostatistician research scientist assigned to provide statistical guidance on its research studies. In addition, one of the collaborative biostatistician researcher scientists leads the Regional Research Statistical Support team, which supports medical center-based researchers.
