His studies have examined health care for adults with chronic conditions, efforts to improve quality by increasing access to care in integrated delivery systems; managed care and physician referrals; managed care and patient-physician relationships; cost-effectiveness of preventive services for older adults; fluoridation effects on oral health and dental demand; financial incentives and dentist adoption of preventive technologies; effects of dental insurance on dental demand, and the link between mother and child access to dental care.
