Robotics and Intelligent Machines
Autonomous drone navigation in GNSS-denied environments is challenging because conventional systems rely on rigid spatial representations, require environment-specific training, or are too c…
ISEF · 2026
Earth and Environmental Sciences
Access to safe drinking water remains a pressing global challenge, with millions exposed to heavy-metal contamination each year. At the same time, fertilizer runoff degrades water quality th…
ISEF · 2026
Physics and Astronomy
Black hole X-ray binaries contain a black hole that accretes gas from a companion star, producing bright X-rays. By fitting the X-ray spectra with astrophysical models, we can estimate key p…
