How do you think your research will impact society in a positive way?

I hope that the insights we gain from probing the nanoscale electronic properties of applied materials will lead to improvements in their performance. This could include better surface acoustic devices from ferroelectrics with application to wireless communications, better phase change memory for computing, and of course better photovoltaics.
