I work as an engineering consultant in the areas of audio/image signal processing, machine learning, information retrieval, and data mining.

I was an NSF-sponsored postdoctoral fellow and research engineer at iZotope, maker of Emmy Award-winning audio production and enhancement software.

Before that, I was a research engineer at Imagine Research, acquired by iZotope in 2012.

I live and work in San Francisco, USA.
