I create experiences from ideation, through development and into testing

About
I work to ideate, design, develop and test novel solutions and techniques for creating pleasant and streamlined end-user experiences. From mobile technologies, to web, to cross-reality experiences, I've worked in a number of domains to develop new ways for people to interact with information in a more intuitive manner. My experience as a research scientist and systems engineer has allowed me to experience and touch the product lifecycle at all points, and it's my belief that efficient, quick iteration lets products flourish. I'm looking for opportunities that would allow me to work closely with a team and end-users to build technologies that improve and simplify everyday life experiences.

Projects
XR-COP

XR-COP

DEVCOM Army Research Labs

A virtual reality command and control application for the Army which supports distributed collaboration using 3D terrain maps. I've supported developing, evaluating, and conducting field test of the XR-COP with soldiers out in the field.

Eye-Gaze AR Information Mediation

Eye-Gaze AR Information Mediation

DEVCOM Army Research Labs & UT Austin

A collaboration between ARL and UT Austin. We constructed an AR system and ran a study showing how eye-gaze in Augmented Reality (AR) can help reduce cognitive burden by hiding unnecessary information in a congested environment.

Fuse

Fuse

Carnegie Mellon HCII

Based on my thesis work, Fuse allows users to manage, and compile their messy browser tabs in to a structured workspace. It's available now as Skeema, a chrome extension from my collaborators at CMU.

Meta

Meta

Carnegie Mellon HCII

A core part of my thesis work, Meta is a tool that allows users to extract and compare entities (in this case products) across websites. From a search, it would collate the most recommended products from a variety of sources into a single view. See more in my linked thesis.
