About: My research interests are at the intersection of audio signal processing, machine learning, and human-computer interaction.
I received my PhD and MA from CCRMA, Stanford University and MS in Electrical Engineering, also from Stanford. During my graduate studies, I was advised by Prof. Ge Wang with additional work with Prof. J. S. Abel and J. O. Smith III. I received my Bachelor of Music and BS in Electrical Engineering at the University of Miami-FL. Before joining Adobe, I worked on audio algorithms at Apple for 4.5 years.
