We investigate heterogeneous reactions occurring on ice, environmental particle and nanoparticle surfaces to better understand the atmospheric pollution processes and their impact on human health using spectroscopic techniques.
We focus on method development of radiochemical analyses for use in routine and emergency response scenarios.
We conduct multidisciplinary research to understand water and indoor and outdoor air pollution and their impact on human health.
We study the immunological aspect of the system biology effects from genetic susceptibilities and environmental stress defined as the exposome on autoimmune diseases, immune deficiencies, and neurodegenerative and neurobehavioral illnesses.
We study human exposure to toxic metals/metalloids (biomonitoring) and long-lived nuclides (radiobioassay); and develop novel speciation methods by coupling LC and GC to ICP-MS, while using portable XRF for field-based studies.
We develop analytical methods to identify unknown chemicals in foods and environmental samples including toxic compounds and chemical terrorism agents, thus providing national surveillance of the food supply.
