update on 15 Jul 2024

A very warm welcome to Dr. Seigi Karasaki! He is joining us as a Postdoctoral Research Fellow supported by the National Cancer Institute T32 Training Program on Cancer Health Disparities (T32 CA094880). Dr. Karasaki received his PhD and MS from the Energy and Resources Group at the University of California, Berkeley. He brings expertise in environmental justice, community-based research methods, machine learning, and geospatial science. We are so excited to work with Dr. Karasaki!

update on 7 Mar 2024

Published the methodology paper for our new geospatial light exposure model for solar jetlag - or the mismatch between the sun clock and the social clock. We developed a scalable geospatial workflow that enables the development of a light exposure model at a 30 m spatial resolution for any spatial extent, temporal resolution, and temporal extent to conduct epidemiologic studies. This model incorporates data on time zone position, sunrise times, sunset times, and elevation by leveraging Google Earth Engine and geemap. This model was validated using LYS Button wearable light sensors. More information on model development and collaborations can be found on our ArcGIS StoryMap: www.fredhutch.org/lightmodel

update on 6 Feb 2024

Published a conceptual framework that illustrates how geospatial science is applied to environmental epidemiology in practice and through the lens of the exposome research paradigm. This paper was inspired by our 2023 Geospatial Science Methods Workshop at the American Association for Cancer Research (AACR) Annual Meeting in Orlando, FL. More info on the workshop can be found here: bit.ly/aacrgeospatial

Named one of the 2024 Geospatial World Rising Stars, an initiative to highlight the exceptional accomplishments of individuals under 40 who are applying geospatial science tech to positively impact the environment, economy, and society

HAAPI CC Fred Hutch

update on 14 Sep 2023

Serving as Chair of the Social & Environmental Working Group to provide expertise in geospatial science, environmental epidemiology, and social determinants of health for a new prospective cohort called the Multi-ethnic Observational Study in American Asian and Pacific Islander Communities (MOSAAIC). Fred Hutch will serve as the Coordinating Center for 5 sites across the US that will recruit at least 10,000 Asian American, Native Hawaiian, and Pacific Islander persons to better understand risk factors for cardiovascular disease and other health outcomes.
