Identifying Exposure Risks from Common Household Chemicals in Durham Homes

The Hsu-Kim group will be helping to start-up a new project in Durham, North Carolina to examine exposures to chemicals derived from materials inside the home and evaluate mitigation strategies to reduce exposures for families.

Vesicle Project Website

The Hsu-Kim group is part of an interdisciplinary team investigating extracellular vesicles (EVs) in the environment. EVs are cellular secretions packaged in a nano-sized phospholipid envelope and are generated by organisms for a variety of reasons,...

Bridging Policy, Research, and Implementation in ASGM

Artisanal and small gold mining (ASGM) typically entails the use of liquid elemental mercury to extract gold from soils and sediment. This practice occurs in more than 70 countries around the world and collectively contributes the largest source of...

Dr. Faye!

Congratulations to Dr. Faye Koenigsmark for successfully defending her PhD dissertation titled "From Source to Surveillance: An Assessment of Liquid Elemental Mercury Mobilization in Soil, Downstream Reactivity, and Biomarkers of Exposure". Well done!

New Year, New Building!

We've finished moving to our new lab in the Pratt School's new Wilkinson Building!       And to the Hudson Hall labs, we bid you a bittersweet farewell. Thanks for the great memories and heartaches! We've finished moving to our new lab in the Pratt School's new…
