I work as a Deep Learning Algorithm Engineer at Apple. Previously, I worked for Intel Corporation and Motorola/Lenovo.

I received my PhD from The University of Texas at Austin, where I worked with Alan Bovik and Paola Passalacqua.

I make educational videos on machine learning, computer vision, and image processing on my YouTube channel.

I use artificial intelligence and creative algorithms to create art. Check out my artwork on Instagram and SuperRare!
