Earth and Environmental Sciences Third Award
The chemical class, Per- and Polyfluoroalkyl Substances (PFAS), first used in the 1940s for ScotchgardTM and TelfonTM has grown to be a chemical class of 12,039 variants. Recently, health co…
ISEF · 2025
Earth and Environmental Sciences
My project focused on the effect of fire mitigation on avian biodiversity as measured through bioacoustics, to ultimately understand forest health. It was inspired by the controversy that oc…
ISEF · 2025
Earth and Environmental Sciences
Acres burned by U.S wildfires have increased since the 1980s, due to warmer temperatures. Over 7 million acres have burned per year in the past 20 years (NOAA). Wildfire plays an integral ro…

Earth and Environmental Sciences
Tornadoes have various wind speeds throughout their life cycles and are usually warned by the National Weather Service to protect life and property. I analyzed data on select tornadoes (2011…
ISEF · 2025
Earth and Environmental Sciences
Approximately 3.5 million people die annually due to inadequate water resources. More than 90% of pollution-related deaths occurred in low-income and middle-income countries. Although resear…
ISEF · 2025
Earth and Environmental Sciences
Greenhouse gases, with carbon dioxide (CO2) being the most significant contributor, are the primary causes of climate change. Atmospheric CO2 levels have risen dramatically from pre-industri…

Earth and Environmental Sciences
This project assessed whether pine tree ring growth could be used to track rates of saltwater intrusion by analyzing pine tree growth ring response to surface water specific conductance leve…
AJAS · 2025
Earth and Environmental Sciences (inferred)
Global warming is rapidly melting glaciers, causing sea levels to rise and shorelines to encroach on communities and animal habitats. This results in coastal erosion, increased storm surges,…
ISEF · 2025
Earth and Environmental Sciences
Coronal Mass Ejections alter space weather, causing geomagnetic storms, atmospheric density disruptions, and ionospheric turbulence, damaging over 2 trillion dollars of satellites and power…
ISEF · 2025
Earth and Environmental Sciences
A healthy stream is vital to the local ecosystem for many reasons. The stream helps regulate floodwaters, filters pollutants, serves agricultural purposes, and maintains a balanced ecosystem…
ISEF · 2025
Earth and Environmental Sciences
California experiences reoccurring earthquakes along its fault lines; however, since 1906, the southern region of the San Andreas Fault System has not produced a 6.5 or higher magnitude (M)…
ISEF · 2025
Earth and Environmental Sciences
Coral reefs support over 25% of marine life and play a critical role in producing 50% of the oxygen we breathe. Scientists predict that by 2030, 90% of coral reefs will be endangered due to…
ISEF · 2025
