Research interest focus on occupational and environmental epidemiology including exposure assessments for epidemiological studies. Exposure assessments involve the development of new and innovative exposure assessment methods and application of these methods to cohort and case-control studies of exposed populations. Research topics include occupational lung diseases and occupational and environmental carcinogens such as asbestos fibers, man-made fibers, and benzene. Epidemiological studies involve the development of quantitative risk estimates for occupational diseases among cohorts of workers exposed to substances such as asbestos. Other ongoing occupational lung disease studies include assessments of exposures and lung diseases among construction workers at Department of Energy nuclear facilities. The objective of this research is to identify possible occupational and personal factors related to the risk of lung diseases such as asbestosis, silicosis,and COPD.

Construction industry health and safety research is another area of research focus. This research includes development of epidemiological surveillance methods for work related diseases and injuries using existing data sources such as medical claims and worker compensation data. Work related musculoskeletal diseases among carpenters are currently being studied in collaboration with the United Brotherhood of Carpenters.

Other ongoing research includes the development and implementation occupational safety and health surveillance systems for health care workers. The objective of this research is to develop, implement, and evaluate a model surveillance program which can be implemented in other health care settings. This project involves both population-based and case-based surveillance strategies. Surveillance and prevention programs for workplace violence experienced by health care workers is a research interest,

Prevention and management of diabetes and cardiovascular diseases among workers participating in multi-employyer health funds is a current area of research interest.
