Portfolio

I have had the opportunity to conceptualize and develop designs in both the physical realm of product design and the digital realm of human-computer interaction (HCI). There is a surprising congruence between the design processes in both realms: I start with design sketches, select and refine ideas based on discussions with the team or the customer, and finally prototype and refine the design over time. On this page, I have some select examples of this design process in HCI and product design.


HCI & Data Visualization


Most of my HCI projects listed here are part of my research on making sense of design collaboration through multimodal data. They prominently feature visual analytics, i.e. the use of interactive visualizations to facilitate analytical reasoning. More recently, I have started to include personal/fun projects to this list.


Real-Time Map of the San Franscico Muni Transit System


sf muni map

A real-time visualization of the San Francisco Muni Transit, created using D3.js and the NextBus XML Feed. Bus locations update every 15 seconds.

Design & Prototyping


My design projects listed below are mostly part of graduate courses in design and prototyping. As in the case of my research projects, these are also the result of teamwork, many late nights, and tremendous fun.


Autonomous Can-Collecting Robot

Insufflator Trocar Redesign


insufflator teaser

A redesign of an insufflator: a device for inflating the abdominal cavity in preparation for laparoscopic surgery. This was done mainly as an exercise in (re)design for manufacturability and assembly.
