The development and application of the Environmental Relative Moldiness Index (ERMI)
(JOURNAL) [Published : Mar 01, 2025]
The prevalence of asthma in the United States (U.S.) has doubled since 1970, coinciding with the increased use of gypsum-drywall in home construction. Mold growth is promoted when gypsum-drywall gets wet. Since asthma is linked to mold exposures, accurate quantification of mold c...
Effects of simulated smoke condensate generated from combustion of selected military burn pit contents on human airway epithelial cells

Community Health: Air Pollution in West Oakland, California
(PRESENTATION) [Presented : Aug 16, 2024]
We present this work as a presentation and a white paper that can be shared with community partners. In this work, we conducted a preliminary analysis of air pollution data (including criteria air pollutants and air toxics), demographics, and health outcomes in the community of W...
Mild allergic airways responses to an environmental mixture increase cardiovascular risk in rats
(JOURNAL) [Published : Jan 01, 2023]
Recent epidemiological findings link asthma to adverse cardiovascular responses. Yet, the precise cardiovascular impacts of allergic airways disease alone have been challenging to disentangle from the potential cardiovascular effects caused by asthma medication. The purpose of th...
Animal models and mechanisms of tobacco smoke-induced chronic obstructive pulmonary disease (COPD)
(JOURNAL) [Published : May 14, 2023]
Chronic obstructive pulmonary disease (COPD) is the third leading cause of death worldwide, and its global health burden is increasing. COPD is characterized by emphysema, mucus hypersecretion, and persistent lung inflammation, and clinically presented with chronic airflow obstru...
Editorial: Climate change is a children's health hazard
(JOURNAL) [Published : Oct 24, 2024]
