Grieshop Atmosphere and Environment Lab [GAEL]

Welcome to the research group website of Dr. Andrew Grieshop, in the Department of Civil, Construction and Environmental Engineering at North Carolina State University, in sunny Raleigh, North Carolina (not pictured above...).

Our research focuses on understanding the sources, atmospheric evolution and impacts of aerosols (airborne particulate matter) and other air pollutants. Projects include work measuring in-use emissions from stationary and mobile combustion sources and developing a more complete understanding of how they evolve once in the atmosphere. I am also interested in developing simple modeling tools to quantify the impacts that air pollution emissions can have on personal exposure, urban air pollution and climate change.

I am interested in conducting research in both domestic and international settings - the latter is where the impacts of environmental pollution are often most drastically felt. For example, the header photo shows the skyline of Delhi, India, where air pollution levels are typically far higher than are ever experienced in the US. To see this in another way, check out this map of global fine particulate matter (PM2.5), showing levels all over the world that are well above those allowed by standards in the US. The photo above also gives you a sense of the air that people in Delhi breathe daily... My group is doing work to help clear skies all over the world.

I am also the Faculty Advisor for the NC State Chapter for Engineers Without Borders (EWB-NCSU), find out more about the chapter here!

The Energy Poverty PIRE in Southern Africa project is underway! GAEL has a key role in this interdisciplinary, international program evaluating the effectiveness of energy interventions in providing energy services and environmental benefits in Malawi, Zambia and Zimbabwe!
