My name is Ross Wang, and I am a PhD candidate
at Georgia Tech.
Roads in the United States are in bad shape
and they are getting worse.
We need to decide when and how we’re going
to repair these roads so we don’t have more
serious problems later.
I’m using 3D sensors to understand how pavement
deteriorates so state DOTs have better data
to make maintenance decisions.
That will improve our roads, and make the 
best use of taxpayers’ money.
