Within the Prototyping group, I manage a small team to design and prototype experimental interface and interaction concepts across all of Apple's products.

Not much of what I make at Apple is directly public. My company has filed patents and patent applications on my work.

Some of the things I’ve been a small part of: iPhone X, True Depth, Touch Bar, True Tone Display, iPad Pro, Apple Pencil, Smart Keyboard, tvOS, Siri Remote, 3D Touch, Force Touch, Taptic Engine, Continuity, Magic Trackpad, Multi-Touch trackpad gestures.

For an overview of my prior work history, here is a single-page résumé.

Open Source


Some of my old work is archived on Github.

I was quite involved with the creation of an instant messaging system called Jabber / XMPP. I designed, built, and (open-source-style-) managed a Linux / Gnome client for it.

Carnegie Mellon

Cognitive Science + HCI

I graduated from Carnegie Mellon University with a Master of Human-Computer Interaction degree. Prior to that I earned a B.S. in Cognitive Science with an additional major in Human-Computer Interaction.
