Lecturer

Bio

Dr. Maria Valdes is currently a Stewardship Manager and Research Scientist at the Field Museum of Natural History. After completing an undergraduate degree at the University of Chicago, she completed a master’s degree at Washington University in St. Louis, a Ph.D. at the University of Brussels, Belgium, and a postdoctoral position at Cambridge University in the UK—and after seven years of traveling, she was very happy for a Chicago homecoming! She studies the history and evolution of the Solar System through the chemistry of meteorites, which she considers windows into our ancient past. Her Fall 2023 course, "The Universe: Its Contents, History, and Evolution" explores the formation of matter in stars, the accretion of that matter into planets and other bodies in our Solar System, and the processes that affected the matter's composition over geological time.

Description

About 9 billion years after the Big Bang, our Solar System's sun ignited from the gravitational collapse of a molecular cloud. This course explores the 4.6 billion years of subsequent chemical evolution of the Solar System. Our tool of study, cosmochemistry, lies at the crossroads of chemistry, physics, geology, astronomy, and biology. As such, we can use it to help us answer some fundamental questions, including: What are the elemental and molecular building blocks of our Solar System? Under what conditions, and by which processes, did these building blocks assemble into planets, asteroids, moons, comets, meteorites, and interstellar dust? What is the Earth made of, how did it evolve over time, and why do we need to study extraterrestrial materials to understand our home planet? Where did water come from and what led to the rise of life on Earth? How can we use this knowledge to guide future space exploration?
