This research investigates how microplastics and nanoplastics affect human cells. Using laboratory models that mimic the digestive system, it examines how particle size and concentration influence toxicity. The findings show that smaller particles are more harmful, providing evidence that can inform safety regulations and reduce human exposure to plastic pollution.

Iowa’s prairies are nearly gone, but restored prairies may cool local climates through evaporative cooling. Deep-rooted, structurally diverse plants increase water transfer to the atmosphere, reducing surface and air temperatures. Using drones, LiDAR, and flux towers, the researcher quantifies prairie cooling as a climate-mitigation tool.

Antifreeze chemicals are toxic. This research tests new ice-recrystallization inhibitors that enter embryos easily, cause minimal developmental effects, and prevent damaging ice-crystal growth. These findings could enable long-term genetic preservation and support future ecosystem restoration.

My research tackles PFAS (polyfluoroalkyl substances) or “forever chemicals,” found in everyday products and linked to serious health risks. Blood testing shows 95% contamination rates. The project identifies specialised bacteria capable of breaking PFAS down nearly completely within days, offering a promising biological solution to reduce environmental and human exposure to these persistent toxic chemicals.
