March 10 - Present

General Technical Director
Olaf’s Frozen Adventure (2017), Moana (2016), Zootopia (2016)
  
Led technology initiatives between Disney, Pixar, Lucasfilm, and ILM to share processes and techniques between our studios. Prioritized software tasks based on risk vs reward for production needs. Designed asset conversion process to support older data from previous productions. Mentored other Technical Directors to complete pipeline/support tasks.

Effects Technical Director
Big Hero 6 (2014), Frozen (2013), Wreck-it Ralph (2012), Tangled Ever After (2012)
 
Product Owner of effects’s code repository, handled code reviews and design decisions for new contributions. Automated fx templates to run based on certain conditionals from front-end departments (animation/layout), saving hundreds of hours. Developed tools in Houdini/Maya to support heavy fx datasets for lighting.

Lighting Assistant Technical Director

Prep and Landing: Naughty vs Nice (2011), Tangled (2010)
Pipeline data management between lighting and effects. Developed publish process for lighting to pick up GL visualization of procedural elements. Rendered lighting shots and composited stereoscopic shots.

Stereo Artist / General Assistant Technical Director

Lion King 3-D (2011)
Stereoscopic compositing. Created depth maps in the original artwork layers to final shot.

Projects

  • Maya Plug-in
    Wrote a Maya Plug-in that automatically rigs a biped character. Based on Baran’s SIGGRAPH 2007 Pinnochio paper [Automatic Rigging and Animation of 3D Characters].
  • Motion Capture
    Experience with UPenn’s SIG Motion Capture Lab. Captured various self-motions in VICON Nexus and used the exported BVH data to design a character controller.
  • Rigid Body System
    Wrote an impulse-based rigid body system, including broadphase and narrowphase collision detection/resolution, contact resolution, gravity, and friction. Narrowphase collision detection based on SIGGRAPH 2003 paper [Nonconvex Rigid Bodies with Stacking].
  • Curve Editor
    Wrote a curve editor for Bezier curves, Hermite curves, and B-splines. User can edit/drag control points to see how it affects the interpolated points accordingly.
  • Automatic Guitar Tuner
    Designed and invented an automatic guitar tuner that twists the pegs of a guitar to the correct pitch when plucked.
