James Tisdall has worked as a musician, a programmer at Bell Labs (where he programmed for speech research and discovered a formal language for musical rhythm), and as a bioinformaticist at Mercator Genetics in Menlo Park, California, and at Fox Chase Cancer Center in Philadelphia. He has a B.A. in mathematics from the City College of New York and an M.S. in computer science from Columbia University; he is working towards a Ph.D. in computer science at the University of Pennsylvania. In his spare time, Jim teaches computer music at the Settlement Music School in Philadelphia. He is also the author of O'Reilly's Beginning Perl for Bioinformatics.
