The speaker shows that using simple hand gestures helps students make abstract fraction concepts concrete. After analyzing fourth and fifth graders’ problem-solving, they found that gestures representing fraction size predicted higher performance. Gesture-based instruction is free, equitable, and effective across demographic groups, offering a powerful tool to improve math learning.

This talk highlights the lack of ADRD resources and care access for capital-D Deaf communities despite their elevated risk. Through community engagement, sign-language translations, and caregiver-informed guidelines, the research seeks to improve equitable aging and end-of-life support for Deaf individuals until a cure for Alzheimer’s becomes reality.

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.
