I am a research scientist at Intel Research
Berkeley. Briefly, the facts of my life as are follows:
And before that I attended Monta
Vista High School in Cupertino, CA, which has since gained an
oddly iconic status in the discourse around the excesses of Silicon
Valley suburbia but seemed pretty ordinary to me at the time.
Research Interests:
I work in the areas of human-computer interaction and
data management systems. I'm basically a systems guy.* On
the HCI side, I design and build systems (including interaction
design) and help out with the fieldwork. On the DB side, I work on
middleware and server technology.
* Admittedly, given what I've been doing recently, I'm saying
this with some degree of irony.
Human-Computer Interaction and Computer-Supported Cooperative Work
My work in HCI has been highly interdisciplinary, mostly sitting in
the intersection of mobile computing and
human interaction.
I am part of TIER, a
project in which Intel is
collaborating with U.C. Berkeley on the design of
appropriate technology
for emerging regions. Various TIER sub-projects have connections with
Intel's Emerging Markets Platforms Group (EMPG) and
Digital Health Group (DHeG).
I am working on a project on mobile participatory
sensing called Common Sense. We are
necessarily exploring some technical issues in sensing environmental
air quality using mobile phones, but the key problem of interest for
us as HCI researchers is to understand how and why people become
engaged in citizen science and environmental activism.
I have collaborated for several years with PARC researchers in the sociological
discipline of conversation analysis; their detailed understanding of
human conversational structure have helped us understand how
(technologically) minor differences in a system can have dramatic
effects on interaction.

is a system we nicknamed Mad Hatter, a mobile
audio space designed for use by small gelled social groups. |
| ... | As part of this work, Allison Woodruff and I
analyzed some fieldwork on young
adults using push-to-talk cellular radios, drawing on several
perspectives in computer-mediated
communication. |
| ... | An earlier example is Sotto Voce, a
networked electronic guidebook system that delivers audio information
in a way that facilitates face-to-face human interaction instead of
inhibiting it. |
All of this work on interaction has also lead to a renewed interest in
wide-area collaborative systems. I spent a lot of my
time at
sea sitting in front of networked tactical command-and-control
consoles.
Finally, I have background in visualization:
information display technology, information visualization techniques
and visualization system architectures. This came through
working
with members of the Tioga
DataSplash database visualization project at Berkeley.
Data Management
|
I consulted on the PARC CSL security group's project (2002-2003) on
privacy-preservation in distributed repositories of personal data.
The Harland project at PARC
has explored the programming affordances of data modelling constructs
that lie between the semistructured and (dynamic) object-oriented data
models. Another consideration is how such constructs can be
supported efficiently. Harland was an outgrowth of the Placeless Documents project
on property-based data stores.

At Berkeley, I worked for Mike
Stonebraker in the database
research group on a variety of topics:
- Database extension technologies
Parallel and distributed information systems
