Graphene attracted a great deal of public interest because of its novel electrical characteristics, structural integrity, high electron mobility, and most important for my work, it was shown to be a room temperature ballistic ...
• #### Transforming the preparation of physics graduate teaching assistants ﻿

(Georgia Institute of Technology, 2019-12-02)
Graduate Teaching Assistants (GTAs) are key partners in the education of undergraduate students. In large-enrollment intro physics classes, students spend roughly half of their in-class hours in labs and recitations under ...
• #### Molecular transport into the outer membrane of gram-negative bacteria ﻿

(Georgia Institute of Technology, 2019-01-15)
This thesis details novel insights gleaned from the application of molecular dynamics (MD) simulations to two protein systems, the $\beta$-barrel assembly machinery (BAM), and the lipopolysaccharide transport machinery ...
