William "Velvel" Kahan was born in Canada and attended the University of Toronto for both his undergraduate and graduate studies in mathematics, and was eventually hired there as a professor. He joined the Berkeley faculty in 1968 with a joint appointment in the Math Department and as a member of the new Computer Science Department in the College of Letters and Science–before it merged with the EECS Department in the College of Engineering in 1973. He retired from the University in 2008. Kahan was instrumental in creating the IEEE 754-1985 standard for floating-point computation in the late 1970s and early 1980s. He developed a program called "paranoia' in the 1980s to test for potential floating point bugs and developed the Kahan summation algorithm which helps minimize errors introduced when adding a sequences of finite precision floating point numbers. Kahan won the ACM A.M. Turing Award in 1989.
Sherry Li is a Senior Scientist in the Computational Research Division, Lawrence Berkeley National Laboratory. She has worked on diverse problems in high performance scientific computations, including parallel computing, sparse matrix computations, high precision arithmetic, and combinatorial scientific computing. She is the lead developer of SuperLU, a widely-used sparse direct solver, and has contributed to the development of several other mathematical libraries, including ARPREC, LAPACK, PDSLin, STRUMPACK, and XBLAS. She earned Ph.D. in Computer Science from UC Berkeley and B.S. in Computer Science from Tsinghua Univ. in China. She has served on the editorial boards of the SIAM J. Scientific Comput. and ACM Trans. Math. Software, as well as many program committees of the scientific conferences. She is a Fellow of SIAM and a Senior Member of ACM.
