Ricardo Cisneros is an assistant Professor of Environmental Public Health. He received a PhD from the University of California at Merced in Environmental Systems.  He also completed a two year postdoctoral appointment in exposure science from the University of California Davis, Department of Public Health Sciences.

His research interests are the effects of air pollution on public health and the environment, and the use of GIS (Geographical Information System) and spatial analysis in exposure assessment and environmental epidemiology. As an environmental scientist with specialization in environmental health and exposure science, he conducts research that recognizes the interdependence of ecological and human health with special interests in Air Pollution Research and exposure assessment. He has conducted several environmental research studies, including determining the impacts of forest fires on air quality.  He was also the first scientist to determine the current PM2.5 background in the Sierra Nevada Mountains and mountain communities in the area. The findings of his research have being used to stimulate policy suggestions and changes by non-profit groups as well as government agencies (both state and federal). He is considered an authority when it comes to the topic of Forest Fires and air quality impacts.

Currently He is working on three projects. One related to two mega fires in California (Rim and Rough fire) and their impact to air quality and human exposure. The second project is about air quality and human attitudes and perceptions. The third is in regards to the intersection of asthma, diet and air pollution.
