Krishna is a PhD student in the 
<!WA0><A HREF="http://www.cc.gatech.edu/gvu/gvutop.html">
   Graphics, Visualization, and Usability Center
</A> of the <!WA1><A HREF="http://www.cc.gatech.edu/Computing.html">College of Computing</A>
at the <!WA2><A HREF="http://www.gatech.edu/TechHome.html">
Georgia Institute of Technology
</A>.
His research advisor is 
<!WA3><A HREF="http://www.cc.gatech.edu/gvu/people/Faculty/Scott.E.Hudson.html">
Scott Hudson</A>. <b>He expects to graduate in June 1996 with a Phd in Computer
Science</b>. His thesis topic is "<i>Supporting the Construction of Distributed, Interoperative,
 User Interface Applications</i>".<P>

His research is directed towards finding new and intelligent ways to
build interoperative, multi-user GUI
applications.  During the last two summers, while at 
<!WA6><A HREF="http://www.research.digital.com/SRC/home.html""> Digital
, Systems Research Center</A>
in <!WA7><A HREF="http://www.city.palo-alto.ca.us/setting/maps/map-bay-area.html"> Palo Alto</A>,
 he developed a direct manipulation application builder for multi-user applications called Visual Obliq
<!WA8><A HREF="http://www.cc.gatech.edu/gvu/people/Phd/Krishna/visualobliq.gif"><!WA9><A HREF="http://www.cc.gatech.edu/gvu/people/Phd/Krishna/visualobliq.gif"> (screenshot)</A> 
with 
<!WA10><A HREF="http://www.research.digital.com/SRC/people/Marc_Brown/bio.html"> Marc H. Brown</A>
and <!WA11><A HREF="http://www.research.digital.com/SRC/people/Luca_Cardelli/bio.html"> Luca Cardelli </A>. 
The Visual Obliq environment now supports the creation of
 Migratory Applications (<!WA12><A HREF="http://www.cc.gatech.edu/gvu/people/Phd/Krishna/Migration.ps.Z">UIST '95, postscript</A></A>)
 (aka Interactive Mobile  Agents), 
a new genre of network-aware applications that can transport themselves to new machines
with the state of their UI intact.
Also,<!WA13><A HREF="http://www.cc.gatech.edu/gvu/people/Phd/Krishna/IWHD.html"> Visual Obliq has been integrated with the World Wide
Web</A>, allowing applications to copied over and executed within a "safe" interpreter
by clicking on a web-link. 
<P>
He is currently working on parallelizing and distributing constraint 
maintenance algorithms.
As a first step in this direction he developed Doppler (<!WA14><A HREF="http://www.cc.gatech.edu/gvu/people/Phd/Krishna/Doppler.ps.Z">UIST '95 -- postscript</A>),
an algorithm for supporting concurrent writes, reads and mutations to
a distributed one-way constraint graph, with
<!WA15><A HREF="http://www.cc.gatech.edu/gvu/people/Faculty/Scott.E.Hudson.html">
Scott Hudson</A>. Doppler delivers Causal Consistency, and provides provably
optimal concurrency for any algorithm that respects causal relationships. He has also
done some work on supporting
<!WA16><A HREF="http://www.cc.gatech.edu/gvu/people/Phd/Krishna/sharedobject.ps"> Persistent, Shared Objects
with Active Fields  in C++</A>,  
with  <!WA17><A HREF="http://www.cc.gatech.edu/gvu/people/Phd/Jeyakumar.Muthukumarasamy.html">
Jeyakumar</A>. Active fields support notification before/after reads/writes and are
a convenient way to maintain constraints and other dependencies between data-fields,
without requiring explicit annotations by the programmer.
