Speaker: Zunli Lu, PhD, Associate Professor, Director of Graduate Studies, Department of Earth Sciences, Syracuse University

Overview: Oxygen is an essential gas for many life forms on Earth today, but it did not exist in the atmosphere during early episodes of Earth history. Geochemists invested great amount of effort to study how trace level of oxygen first appeared at about 2 billion years ago and then rose to its concentration of modern atmosphere. Even when the atmosphere was rich in oxygen, global oceans experienced catastrophic oxygen losses in the last 100 million years. Last but not least, on-going global climate change and nutrient pollution are leading to the expansion of marine dead-zones and more frequent hypoxia. This talk will explore the Earth history of oxygen, addressing causes and evidences for changes in oxygen levels.

Biography: Zunli has been with Syracuse University since 2011 after obtaining his PhD at University of Rochester and completing post-doctoral research at University of Oxford (England). He is interested in using chemical analyses and computer simulations to solve puzzles in the Earth system at different time scales. He is in charge of a clean lab and mass spectrometer to measure trace elements in water, rock and fossil samples. Climate change and oceanography are his main areas of teaching at SU. Other than research, writing and teaching at university, Zunli plays volleyball, table tennis, and particularly enjoys fishing. He’s also learning skating and skiing with his 5 year old boy.

TACNY Junior Cafe Scientifique

TACNY Junior Cafe Scientifique, a program for middle-school students founded in 2005, features discussions about topics in the fields of science, technology, engineering and mathematics in an informal atmosphere and seeks to encourage students to consider careers in these areas. Students must be accompanied by an adult and can explore the MOST at no cost after the event.
