Director of Engineering at eBay in the Innovation & New Ventures Group, working on integrating technology into the retail experience, both online and in store.

Founder and CEO at PhiSix Fashion Labs, a Bay Area technology company helping apparel e-tailers increase sales and reduce returns through the application of innovative 3D modeling and physical simulation technologies. Acquired by eBay Feb, 2014.

Research interests including rigid body and fluid simulation, as well as other aspects of physical simulation and computer graphics in general. In particular, exploring their real-time and interactive applications.

Research on developing a high-fidelity multiphysics simulator, with a focus on scalable, efficient, and stable algorithms. Investigating phenomena such as cloth, compressible and incompressible flow, solid-fluid coupling, and rigid bodies, and how MPI, multithreading and scalable algorithms can enhance these simulations.Publications:http://physbam.stanford.edu/~fedkiw/papers/stanford2012-03.pdfhttp://physbam.stanford.edu/~fedkiw/papers/stanford2009-02.pdfhttp://physbam.stanford.edu/~fedkiw/papers/stanford2008-04.pdfhttp://physbam.stanford.edu/~fedkiw/papers/stanford2008-01.pdfhttp://physbam.stanford.edu/~fedkiw/papers/stanford2007-06.pdf

Development of the Classroom Presenter presentation software advised by Prof. Richard Anderson, in collaboration with Microsoft Research’s ConferenceXP project. Investigating methods for recognition of annotational marks (circles, underlines, etc.) to extrapolate key points from lecture content. Also, implemented mechanisms for real-time student-instructor interaction using TabletPCs.Publications:http://www.cs.washington.edu/homes/jonsu/CG_2005.pdfhttp://www.cs.washington.edu/homes/jonsu/AAAIFS_2004.pdfhttp://www.cs.washington.edu/homes/jonsu/ACMMM_2004.pdfhttp://www.cs.washington.edu/homes/jonsu/ITICSE_2004.pdf

Explored problems in the intersection of graphics and systems, studying z-buffer precision loss considering all operations in the graphics pipeline. The results can be used by systems designers to understand the effective precision their systems will have, as well as by application developers to get a tight estimate of minimum separation distance needed for correct rendering.Publications:http://www.eg.org/EG/DL/WS/EGGH/EGGH06/027-030.pdf.abstract.pdf;internal&action=paperabstract.action
