Postdoc Spotlight: Cosmochemist Nan Liu

Nan Liu

After receiving an offer from the University of Chicago to study cosmochemistry, DTM postdoctoral fellow Nan Liu packed up and moved to the States. While at Chicago, Liu discovered her passion for studying presolar grains, or interstellar dust grains derived from dying stars dating back to before the formation of our Solar System. To her, the coolest thing she could imagine doing for a career was to hold tiny, interstellar fragments of dying stars in her hands every day. We talked to Liu about what she likes most about her field of research, and where she sees her career going in the future following her postdoc at DTM.

Matthew Scott Reveals Why We Should Care About Jumping Genes at His Neighborhood Lecture

Matthew Scott

Carnegie Science President Matthew Scott revealed to a sold out Neighborhood Lecture crowd in the Greenewalt Lecture Hall last week how genes that jump from one place in a chromosome to another, or jumping genes, may have influenced early life on Earth and why exactly we should care about them now. The lecture kicked off our Spring 2017 Neighborhood Lecture Series on Thursday, March 16.


Earth's First Example of Recycling—Its Own Crust!

Richard Carlson

Rock samples from northeastern Canada retain chemical signals that help explain what Earth’s crust was like more than 4 billion years ago, reveals new work from DTM’s Richard Carlson and Jonathan O’Neil of the University of Ottawa. Their work is published by Science.  


Visualizing Debris Disk "Roller Derby" to Understand Planetary System Evolution

Erika Nesvold

New work led by DTM’s Erika Nesvold looks at how a disk is affected by a planet that exists beyond its outermost edge and demonstrates that the disk’s shape can indicate whether the planet formed beyond the disk or initially existed inside of the disk and moved outward over time. The work is published in The Astrophysical Journal Letters.
