4/27/2022: the latest publication from our research in Science of the Total Environment Neighborhood characteristics of low radon testing activities: A longitudinal study in Atlanta, Georgia, United States. Using 25 years of indoor radon screening data, the research highlighted the need in residentially segregated communities to increase radon educational and testing campaign. The article can be access freely before 6/16/2022 by clicking here or through Contact us page.

4/25/2022: our team member Eunhee Kim successfully defended her thesis: Exploring the impact of geology, housing characteristics and season on indoor radon. Thanks to the committee members Dr. Paulo Hidalgo (Geosciences) and Dr. Christine Stauber (School of Public Health). She also received admission to University of Texas at Dallas for her doctoral program in Geospatial Information Sciences. Congrats Eunhee.

4/22/2022: our team member Laurel won second place in GSU Undergraduate Research Conference in the area of Applied Research and Entrepreneurship. Way to go Laurel!

3/5/2022: our team started the pilot survey on a beautiful Saturday in the community. This is the project funded by the Robert Wood Johnson Foundation to test indoor radon collaborating with our community partners. From left to right: Dr. Dai, Ryan, Stephen, Mali, Gwen, and Dr. Osborne-Jelks.

  • 1/26/2022: Dr. Dai gave an invited talk on the neighborhood characteristics of low radon testing activities at the Big Data Health Science Center at University of South Carolina.

  • 1/20/2022: Our lab welcomes two undergraduate research assistants: Laurel Sparks and Daniel P. Prendergast, who will work on the projects funded by the USGS and RWJF, respectively. Welcome Laurel and Daniel!

  • 11/13/2021: Dr. Dai's grant on indoor radon ($359,000) funded by the Robert Wood Johnson Foundation held the first ethnic training to community researchers. The radon test kits have arrived and we will excitedly start the recruitment soon.

  • 10/2/2021: Our student Antwi Opuni recently received 2021 National Association of the Black Geoscientists (NABG) Scholarship in the superior category! Congratulations Antwi!

  • 8/16/2021: We have started the second phase of Geology Mapping of the Southern Half of Chamblee Quadrangle on 8/16/2021. This is the second grant funded by the United States Geological Survey ($49,943) to combine drone mapping and field studies and train next-generation geoscientists using cutting-edge technologies.

  • 7/1/2021: Dr. Dai recently received an internal grant ($50,000) collaborating with public health researchers from GSU School of Public Health and Augusta University School of Medicine. The work will use GIS technologies to study geographical disparities in healthcare access and living conditions on mental and cardiovascular health. This is a longitudinal analysis of 30-year effort in the Central Savannah River Area.

  • 3/30/2021: Dr. Dai recently received $1.1 million support from National Science Foundation as a co-Principal Investigator to study soil radon radiation. This is a collaboration with colleagues from GSU computer science, geologists, and soil scientists. The grant is titled “SitS: A Novel Large-Scale Radon Measurement Wireless Testbed for Spatio-Temporal Study of Radon in Surficial Soil”

  • 6/30/2020: Our lab received $359,000 from the Robert Wood Johnson Foundation as Interdisciplinary Research Leaders to establish a REMOVE program. It is a community-based program to study Radon Evaluation, Mitigation, and Ventilation, and to empower communities to improve environmental literacy and build community capacity.

  • 3/9/2020: Our lab received an EDMAP grant from the United States Geological Survey ($35,097) to build 3D visualization model and geology maps in the Northern Half of Chamblee Quadrangle. We will use drone mapping techniques and field mapping to study the environment and train next-generation geoscientists using exciting technologies.
