I was part of Amazon's speech group that works on speech and language solutions for revolutionalizing how customers interact with Amazon's products and services. Projects such as Echo, Dash, Fire TV and the Mobile Shopping App are illustrative use cases.

I am an author on two pending US patent applications submitted by Amazon.
