<H1> Welcome to UNC Colab group's home page! </H1>

<H2> About Distributed Collaboration </H2>

If you are the average computer scientist, ``distributed collaboration''
is a buzzword to you and you probably do not know much about
this field.
That is because it
is an emerging area not associated with
a large body of knowledge or even a text book!
While this might be bad news if you are a practitioner,
it is actually very good news if you want to be a researcher,
since interesting open problems are easier to find in a new area.
Moreover,
it is not an entirely brand new field -
it is as an interdisciplinary area giving new angles to
several traditional fields.
Traditional computer science has assumed that a single user
interacts with a computer program at any one time.
A whole range of issues emerge when you decide to violate
this fundamental assumption by allowing multiple,
distributed users to simultaneously
communicate with a program.
Research in operating and distributed systems,
programming environments,
user-interface frameworks,
software engineering,
and transaction models has started to study some of these issues,
but there is much left to do.
So if you have an aptitude in any of
these fields (and specially in more than one of them),
then this might be the area for you.


<H2> The People </H2>

This group was started by
<!WA0><a href = "http://www.cs.unc.edu/~jbs">
John Smith,
</a>
when he introduced
<!WA1><a href = "http://www.cs.unc.edu/~jeffay">
Kevin Jeffay
</a>
and 
<!WA2><a href = "http://www.cs.unc.edu/~smithfd">
Don Smith
</a>
to the idea of CSCW (Computer Supported Cooperative Work).
They have not since looked back, using collaboration
as a driving problem for much of their research.
This initial group
developed the ABC collaboration framework,
which includes
a distributed, hypermedia file system and a distributed
shared window system.
ABC was supported by a special
<!WA3><A HREF = "http://www.cise.nsf.gov">
National Science Foundation
</a>
program to investigate collaboration technology.
This program also funded collaboration systems developed by
<!WA4><a href = "http://www.cs.unc.edu/~stotts">
Dave Stotts
</a>
and
<!WA5><a href = "http://www.cs.unc.edu/~dewan">
Prasun Dewan,
</a>
who were then at Maryland and Purdue,
respectively,
but soon saw the light and joined UNC.
They,
in turn,
have contributed to the spreading of the word,
specially to
<!WA6><a href = "http://www.cs.unc.edu/~prins">
Jan Prins
</a>
and
<!WA7><a href = "http://www.cs.unc.edu/~nyland">
Lars Nyland,
</a>
who are the newest members of the group.
<!WA8><a href = "http://www.cs.unc.edu/~wahab">
We expect
<!WA9><a href = "http://www.cs.unc.edu/~anderson">
Jim Anderson
</a>
and
<!WA10><a href = "http://www.cs.unc.edu/~sc">
Sid Chatterjee
</a>
to soon start looking seriously at this area.
Hussein Abdel-Wahab
</a>
has been working with the group
since its inception
as an adjunct faculty member.
Some of the faculty members at other universities we collaborate with are
<!WA11><a href = "http://bush.cs.tamu.edu/~furuta">
Rick Furuta,
</a>
<!WA12><A HREF = "http://www.cs.pdx.edu/~mchugh">
John McHugh,
</a>
and
<!WA13><A HREF = "http://www.cs.umn.edu/~riedl">
John Riedl.
</a>
We are also working with Bill Oliver of AFIPS,
who plans to be a client for much of the software we develop.
The diversity of this group has put it in a unique position
to comprehensively address the broad agenda of this interdisciplinary
area.

Some of the Ph.D. students who have been led into working in
this area are

Jaime Navon.
