His major was mathematical sciences with anemphasis in computer science.For his honors project he helped designand implement <!WA8><A HREF=http://www.cc.gatech.edu/grads/m/Scott.McCrickard/pgoms/>PGOMS</A>,an interface for creating GOMS models.<P><!WA9><A HREF=http://www.epm.ornl.gov/~mccricks>Scott</A> has worked at<!WA10><A HREF=http://www.ornl.gov/>Oak Ridge National Laboratories (ORNL)</A>with <!WA11><A HREF=http://www.epm.ornl.gov/~rowan>Tom Rowan</A> as a memberof the <!WA12><A HREF=http://www.epm.ornl.gov/vis/>Visual andInformation Sciences Group</A>.

If you wish todiscuss any of these topics,please <!WA16><A HREF="#Contact">get in touch</A> with Scott.<P><A NAME="IIMD"><B>Internet Information Monitoring and Display</B></A> is an important area considering the constantly growingand changing nature of the Internet. Resources such as Email, Usenetnews, and the World Wide Web provide a continuous flow of information.While users can access this information using any of a number of readersand browsers, it is difficult to determine when and if a resourceneeds to be accessed. In addition, the large amounts of informationthat accumulate can be difficult to assimilate at a glance.<P>Visualizations are needed that will provide an overview of these resourceswith a detailed look at recent changes. As a result, information aboutthe names and content of the messages and documents must be encoded ina small number of pixels through the use of color, intensity, size,and shape. These techniques are reflected in<!WA17><A HREF=http://www.cc.gatech.edu/grads/m/Scott.McCrickard/irwin/>Irwin</A>, a tool thatmonitors resources and provides various alertswhen changes occur. A multi-layer view of the resourcessimultaneously provides a broad overview of all resources plusa narrow look at recent changes without losing context.<P>Recently, Scott was also part of a team that developed<!WA18><A HREF=http://www.cc.gatech.edu/grads/m/Scott.McCrickard/sqwid/>SQWID</A>, a Java tool for visualizingthe results from an Alta Vista search. SQWID providesa stress-based graph view of the search result sitesthat will hopefully help users identifyinteresting Web sites.<P><B>Program Visualization</B> examines methods for visualizinginformation about a computer program. For years programmers have drawnpictures such as flowcharts or control-flow diagrams to help otherprogrammers and users better understand their programs.Unfortunately, these pictures will not provide theexact desired perspective for every user.Clearly, methods are needed for automatically generatinggraphical representations of programs.<P>Existing code formatters, profilers, and analysis systems provideadequate static and post-mortem views of a program. However,debugging and understanding is aided if the program executionis shown in conjunction with the program code. By visually connectingthe code and execution, the user can identify elements in the programthat otherwise would not be visible.Scott is working on <!WA19><A HREF=http://www.cc.gatech.edu/grads/m/Scott.McCrickard/runview/>RunView</A>,a runtime-based code analysis systemthat incorporates these and other ideas. He is also exploring howRunView can be used to decompose software architectures in a projectwith <!WA20><A HREF=http://www.cc.gatech.edu/fac/Gregory.Abowd>Gregory Abowd</A>.<P><B>Software Visualization</B> is the use of graphics,visualization, and animation as an aid in the understanding ofalgorithms, architectures, and software. Software visualizationscan be constructed using toolkits like<!WA21><A HREF=http://www.cc.gatech.edu/gvu/softviz/algoanim/xtango.html>Tango</A>and <!WA22><A HREF=http://www.cc.gatech.edu/gvu/softviz/parviz/polka.html>Polka</A>.With these toolkits, a programmer creates objects and programs themwith actions that occur over a number of frames.<P>With the advent of improved hardware, the number of frames displayedper second is sure to decrease. Thus, a natural evolution is to specifyactions not in frames but in real time (seconds and milliseconds).This concept is central to Polka-RC (Polka Real-Clock), an evolution ofthe original Polka system with the added capability of time-basedanimation activations and durations. In addition, Polka-RCprovides more natural ways to describe actions and their relationshipto objects. Tech report<!WA23><A HREF=file://ftp.gvu.gatech.edu/pub/gvu/tech-reports/95-21.ps.Z>GIT-GVU-95-21</A> discusses these ideas in detail.<P><B>Wait-Free Consensus</B> reflects the ability of <I>N</I>distributed objects to ``agree'' in the presence of <I>N-1</I> failures.A number of object parameters can impact on this ability to agree. See<!WA24><A HREF=file://ftp.cc.gatech.edu/pub/coc/tech_reports/1994/GIT-CC-94-04.ps.Z>GIT-CC-94-04</A> for a discussion of these parameters and a look at theproperties of some distributed objects.<P><HR><H2>Teaching</H2>Scott has TAed a number of courses at both the graduate andundergraduate levels, including <!WA25><A HREF=http://www.cc.gatech.edu/computing/classes/cs6751_95_fall/>CS 6751</A>(Human-Computer Interaction), CS 1155 (Understanding and Constructing Proofs),CS 4753 (Human Factors in Software Development), andCS 6152 (Theory of Automata). His TA position has required that hecreate and grade homeworks and projects, assist students, maintainWeb pages, and teach classes on occasion.<P><HR><H2>Personal</H2>In his free time, Scott plays tennis for an ALTA team,with its best finishes city runner-up at B5 and division champsat A6. He also (less regularly) plays other sports,including softball, basketball, and fencing.He even took up golf recently in an effort to better understand<!WA26><A HREF=http://www.cc.gatech.edu/gvu/people/Faculty/john.stasko/golf/>his advisor</A>. (It didn't work, and Scott sank still furtherinto debt.)For the past two summers while in the Oak Ridge area,Scott got to ski, skurf, slalom, disk, and do other water activitiessince he had a lake in his backyard.He spends too much time on the Web, as evidenced by the size ofhis <!WA27><A HREF=http://www.cc.gatech.edu/grads/m/Scott.McCrickard/hotlist.html>hotlist</A>.Scott is tired of writing about himself in the third person.<P><HR><A NAME="Contact"><H2>Contact information</H2></A><ADDRESS>D.
