Research Themes
Early Earth
Around 4.5 billion years ago, the early Earth was characterized by high volcanic activity, a thin atmosphere dominated by nitrogen and carbon dioxide, and a primordial ocean. Over millennia, harsh conditions gradually gave way to the birth of life and shaped the planet's geological and atmospheric evolution.
Extreme Environments
Extreme environments, from dry and cold deserts to deep-sea hydrothermal vents, challenge the limits of life on Earth. Micro-organisms, known as extremophiles, thrive in environments with high temperatures, acidity, salinity, and pressure. Studying such ecosystems provide valuable insights into the potential habitability of other celestial bodies and expands our understanding of the diversity of life in the universe.
Origin of Life
The origin of life is an enigma, eluding a definitive explanation. Theories such as abiogenesis propose life emerging from non-living matter, while panspermia suggests extraterrestrial origins. This mystery fuels scientific exploration, as researchers seek clues in the cosmos and delve into the intricate biochemical processes that define life's inception on Earth.
