Our research aims in understanding the coupling between particulate pollution, climate change and human health
Organic aerosol and NMR
Understanding how atmospheric particles afffect our health is limited by the largerly unknown composition of the organic carbon. We utilize 1-D and 2-D nuclear magnetic resonance coupled with GC/MS, HPLC/MS and factorial analysis to identify the functional groups and molecular characteristics of organic aerosol
Public safety workers (police officers, firefighters, emergency medical personnel) are exposed to many physical, chemical and phychological hazards while on-duty. Our research aims in developing better methods to assess exposures to chemical and physical hazards and link them to specific biomarkers of disease.
A major source of air pollution around the world with direct links to changing climate. We are working on understanding the chemical composition of smoke, how smoke influences air quality, respiratory and cardiovascular function and metabolites, mobidity and mortality.
Air quality and GIS
Air quality is locally important but regionally controlled, as air masses moves around tranferring pollutants from one place to another. Having the ability to examine air quality on a regional scale by big data analysis is essential in understanding and solving problems.
Electronic cigarettes are devices designed to deliver vaporized nicotine with flavor additives to users. This heating process can lead to to chemical transformations generating the production of harmful compounds. Our research attempts to characterize the chemical composition of vapors with emphasis on heating byproducts.
Climate and health
Climate change is happening and directly affects our health. Outbreaks of rare diseases, extreme weather, severe air pollution are some of the outcomes. We study how environmental and human factors are changing in response to climate change and the links with morbidity and mortality.
