Professor Domyung Paek's research lab focuses on environmental health and preventive medicine, with a strong emphasis on understanding the health impacts of airborne exposures—particularly from household products like humidifier disinfectants and environmental pollutants. The lab investigates dose-response relationships, respiratory deposition patterns of inhaled particles, and the physiological and psychological benefits of forest-based therapeutic interventions. It also explores risk cognition and policy responses to hazardous substances such as asbestos, integrating epidemiological, physiological, and public health perspectives.

Dose-response analysis indicated that development of humidifier disinfectant lung injury and death were associated strongly with recurrent, intense, acute exposure without sufficient recovery time between exposures, more so than long-term cumulative exposure. These findings may explain some reversible or clinically unapparent cases among coexposed family members.
The level of ventilation attained and breathing patterns adopted during activity have important implications for the distribution and deposition of particles that are inhaled. However, breathing patterns and levels of ventilation adopted during specific physical activities are unknown. We used a noninvasive means of measuring ventilation in subjects performing a variety of activities (bicycling, arm ergometry, lifting, and pulling) during unencumbered (no mouthpiece) breathing and while breathin
Risk cognition is a complex process, but the presence of well-functioning health infrastructures, as well as the increased social cost of mesothelioma, that can make the plight of asbestos victims visible to the eyes of public and policy makers, may have contributed to this process. Asbestos ban policy from adjacent countries might have facilitated the adoption of alternative solutions.
Various effects of forest healing on health have been reported, but a certification system to assess the effectiveness of forest healing programs does not exist. In this study, a systematic review (SR) on the "health benefits of forests" and "meta-analysis of forest therapy" was conducted after analyzing the status and level of evidence of 75 forest healing programs that were conducted post-certification in South Korea. The SR for "health benefits of forests" distinguished between activities and
