Bio

I am a Professor in the Department of Computer Science and Engineering at the University of South Carolina. My principal research interests are the algorithms and architectures for performing computations, such as those in discrete mathematics and text/string processing, for which traditional computer architectures oriented toward floating-point computations normally perform at a significantly reduced efficiency. One class of such problems are those computational problems in number theory for which fast integer arithmetic, often multiprecision arithmetic, is necessary. Another broad class of problems are those for which "custom computing machines" were devised. These include bit-oriented computations such as those done in string processing, and image processing computations, for which one often needs substantial parallelism, but for which 8-bit or 12-bit arithmetic is often sufficient accuracy.

In past lifetimes I was an instructor in mathematics at Carleton University in Canada (1976-77), a faculty member in computer science at Bowling Green State University (1977-1979) and Louisiana State University (1979-1985),and most recently a member of the research staff at the Center for Computing Sciences of the Institute for Defense Analyses (1986-2000). Among other things at IDA/CCS I directed the Splash 2 project building a custom computing machine that used Xilinx FPGAs as the compute elements and whose applications were programmed in VHDL. Commercialized versions of and variations on Splash 2 are available from several vendors, including Annapolis Microsystems, Inc. (with whom I have no financial connections whatsoever). As part of popularizing the concept of custom computing machines, we created a conference, held annually since 1993, now called the IEEE Symposium on Field-Programmable Custom Computing Machines (www.fccm.org).

Some comments and links elsewhere

I have been involved in various ways since the the beginning of the the FCCM conference in reconfigurable computing. This is one of two major U.S. conferences on the use of programmable gate arrays in computation.

Last year I was a keynote speaker at the Reconfigurable Systems Summer Institute at NCSA in Urbana. This year's RSSI is scheduled for 12-14 July, and I am scheduled to speak again.

As someone who cares very deeply about the principles of governance laid down by Jefferson and Madison as well as the development of technology that outstrips the ability of law and society to keep pace, I am concerned with the use of electronic voting machines whose evaluations of quality and security are not open to public scrutiny. I therefore point the interested reader to various links on electronic voting. am also concerned with U.S. education in the STEM (science, technology, engineering, and mathematics) fields, and I have been involved as it seemed necessary for more than 25 years in defending science education against attacks from supporters of nonscience, pseudoscience, and the occasional downright fraudulent dishonesty. In that spirit I commend to the reader the award-winning website of the National Center for Science Education, the Talk dot Origins website and its award-winning subsite Panda's Thumb, the almost unbelievably clear prose of the Kitzmiller decision, the website information from the American Association for the Advancement of Science, the National Science Teachers Association, the National Academies, the Federation of American Societies for Experimental Biology, and from South Carolinians for Science Education. The science standards in South Carolina require that students learn how it is that scientists go about a "critical analysis" of that which is to be considered science. These websites can provide that information. As is indicated by the recent press release and position statement by the Interacademy Panel on International Issues representing many of the world's science academies, that critical analysis has clearly been done and the conclusions (at least at the level of K-12 science education) are clear as to what students need to learn.

I grew up and went to high school on the north shore of Lake Pontchartrain. Much of my family still lives there, so I have a strong personal interest in the effects of Hurricane Katrina and the attempts to rebuild New Orleans in such a way that a colossal failure of "the system" could not happen again. In the spirit of laissez les bon temps roulez encore, I point to the plan and the map from the Bring New Orleans Back Commission

In addition to the above, I update from time to time some other links of possible interest.
