Jeremiah Shuster investigates one of science’s most profound questions: How did life begin on Earth, and could it exist elsewhere in the universe? His research focuses on extremophiles—microbes that thrive in environments most life cannot, such as boiling hot springs, hypersaline lakes, and acidic systems. These organisms often leave behind microscopic traces in rocks, preserving structures and chemical signatures that act as clues to early life. By studying these biomarkers, Jeremiah works to reconstruct how life originated, evolved, and influenced Earth’s biogeochemical cycles.

To analyze these ancient traces, Jeremiah employs advanced imaging techniques, including high-resolution scanning electron microscopy (SEM) and transmission electron microscopy (TEM). These tools allow him to visualize fossilized microbes and their nanoscale features, providing insights into how life was preserved over billions of years.

Jeremiah’s work also extends beyond Earth. Because extremophiles thrive under conditions similar to those found on other planets (e.g., Mars), they serve as analogues for potential extraterrestrial life. His research helps guide the search for biosignatures on planetary surfaces and informs future space missions. Jeremiah's research integrates geology, microbiology, and planetary science to explore life’s origins and its possibilities beyond Earth. His work reflects a deep curiosity about our place in the cosmos and contributes to advancing astrobiology on a global scale.
