ScienceMatters:The Podcast of GT College of Sciences Georgia Tech College of Sciences

The new dean of the Georgia Tech College of Sciences, Susan Lozier, is continuing her physical oceanography research as she takes the reins of her administrative duties in Tech Tower. She talks about her studies of “the global ocean conveyor belt,” her plans to get back to the ocean in 2020, and her commitment to mentorship.  

 Cosmologists use computers simulations to recreate the birth of stars and black holes. James “JC” Gumbart, an associate professor in the School of Physics, goes in the other direction: He uses powerful hardware and software to chart the possible paths of molecules like proteins in hopes of finding solutions to problems like antibiotic-resistant bacteria.    

Gardeners love peat moss; it’s great for growing. But Joel Kostka, professor in the School of Biological Sciences and the School of Earth and Atmospheric Sciences, wonders if it serves as a warning sign for the impact of climate change on plants and microbes. He travels to a unique experimentation site in Minnesota to find answers to his questions.  

Georgia Tech science powers the technology behind TV and smartphone screens, thanks to breakthroughs in physics, chemistry, and materials science. Carlos Silva is adding to that legacy with his research into the next generation of semiconductors for electronic devices.
   

School of Biological Sciences Associate Professor Lewis Wheaton uses his Cognitive Motor Control Lab to research the neurological processes involved when people cope with the loss of a limb, a stroke, or a traumatic brain injury that can impact motor skills.

Sally Ng is one of the top experts in the world on aerosol science, the study of tiny particles in our atmosphere and what they mean for our climate, and our health. Ng, an associate professor in the School of Earth and Atmospheric Sciences, describes her work testing air quality in the field, and in a special indoor lab that she designed.
