DESCRIPTION:Exoplanet detection surveys over the last twenty years have re
 vealed a\nsurprising diversity of planets orbiting other stars -- this rev
 olution is\nfueled by fundamental questions about the place of the Earth a
 nd the Solar\nSystem in the Universe. How do planets form? What range in a
 rchitectures of\nplanetary systems exist? How does our Solar System fit in
 to this context? \nThe study of exoplanet atmospheres is the next step in
  leveraging\nexoplanetary detections. This is because a planet’s atmosph
 ere provides a\nfossil record of its primordial origins and controls its f
 ate\, size\,\nappearance\, and ultimately its habitability. In this contex
 t\, I present\ncomparative exoplanetology programs that aim at characteris
 ing planetary\nsystems transiting nearby stars through the observations of
  their\natmospheres. Our findings on the atmospheric composition and physi
 cal\nproperties provide insights into the formation and evolution of plane
 tary\nsystems and enhance our understanding of our own Solar System’s fo
 rmation.\nFinally\, I also present strategies for probing habitable exopla
 net\natmospheres in the quest for bio-signatures.\n
