Higher education institutions like Duke are gateways to opportunity and success for many low-income and first-generation college students. They are also home to professors who once stood in those students’ shoes and used their education to get into academia. Here are some professors from Duke who were low-income, first-generation (LIFE) college students.

If you ask Duke assistant professor Dan Scolnic what amazes him about cosmology, he’ll say, it’s “really the only field in all of science where you could stand in front of people and say, ‘we understand 5% of what’s going on,’ and still think we’re kind of smart.”
That’s because all the stars, planets and galaxies that scientists see today make up just 5% of the universe. The other 95% is made of mysterious stuff called dark matter and dark energy that scientists can’t see or detect directly.
Scolnic says scientists may be… read more about Prestigious Packard Fellowship Supports Duke Cosmologist in Answering Questions About What Makes Up the Universe »
Graduate student Yiqiu Zhao and colleagues have been featured in an APS Viewpoint. Zhao summarizes: Granular matter can behave like solid or liquid. A phase diagram that predicts the behavior of granular matter based on control parameters is important but not well established. Part of the difficulty is, granular matter develops spatial heterogeneity known as shear band under shear, making it hard to build connections between state variables since a well-defined “state” should be homogeneous. In this work,… read more about Grad Student Zhao and Colleagues in APS Viewpoint »

The early 1990s were heady times for Duke physicists Al Goshaw and Mark Kruse.
They belonged to one of two rival teams racing to discover an ephemeral building block of nature called the top quark.
The final missing piece in a puzzle, the top quark was the last undiscovered quark of the six predicted to exist by scientific theory. “This was one of the major discoveries in our field,” said Goshaw, James B. Duke Professor Emeritus of Physics.
In 1995, the two 450-person teams working on a machine near Chicago called the… read more about Duke Physicists Share Prize for Discovery of the Top Quark »
