He has a particular interest in mobile-health tools that are being used with increasing frequency in health care and biomedical research. As a biostatistician, Dr. Di focuses on the analysis of functional and longitudinal data, statistical inference for complex models, and their application in physical activity epidemiology and other mobile-health studies. Motivated by ancillary studies of the Women\u2019s Health Initiative, Dr. Di and his colleagues have been developing cutting-edge statistical methods for accelerometer-measured physical activity data, including novel metrics for activity intensity, frequency and duration, as well as flexible functional data analysis and compositional analysis tools for quantifying dose-response relationships between activity patterns and health outcomes. He has also been involved in other mobile-health studies that utilize mobile apps and wearable devices for improved measurement, monitoring and intervention, including smartphone-based behavior interventions and a wearable electrocardiogram monitoring patch for assessment of cardiac rhythm abnormalities.<\/p>\n","protected":false},"featured_media":457,"menu_order":0,"template":"","group":[8],"class_list":["post-538","persons","type-persons","status-publish","has-post-thumbnail","hentry","group-faculty"],"job_title":["Faculty"],"email":["cdi@fredhutch.org"],"last_name":"Di","_links":{"self":[{"href":"https:\/\/depts.washington.edu\/uwbirch\/wp-json\/wp\/v2\/persons\/538","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/depts.washington.edu\/uwbirch\/wp-json\/wp\/v2\/persons"}],"about":[{"href":"https:\/\/depts.washington.edu\/uwbirch\/wp-json\/wp\/v2\/types\/persons"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/depts.washington.edu\/uwbirch\/wp-json\/wp\/v2\/media\/457"}],"wp:attachment":[{"href":"https:\/\/depts.washington.edu\/uwbirch\/wp-json\/wp\/v2\/media?parent=538"}],"wp:term":[{"taxonomy":"group","embeddable":true,"href":"https:\/\/depts.washington.edu\/uwbirch\/wp-json\/wp\/v2\/group?post=538"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
