Mei Kobayashi graduated from Princeton University with an A.B. in Chemistry and the University of California at Berkeley with an M.A. and Ph.D. in Pure and Applied Mathematics. She has been a Researcher at IBM for over 20 years, during which she worked on developing algorithms to solve inverse problems, simulations in low-end DASDs, wavelet analysis for speech synthesis, data hiding, information retrieval, data mining, and web log analysis. Recently, Mei was a Technical Assistant to the Director.

While at IBM, Mei has taught courses on Matrix Computation and Wavelets at the University of Tsukuba, Hiroshima University and the University of Electro-Communications, and has given lectures on data mining at the Waseda University Digital Campus Consortium and the Kyoto University Global Center of Excellence. She was a Visiting Professor at the Graduate School of Mathematical Sciences at the University of Tokyo for three years. Mei's research interests include computational chemistry, numerical analysis, matrix computations, signal processing, wavelets, information retrieval and data mining.

She has served on Technical Program Committees of SIAM International Conference on Data Mining and Text Mining Workshops, IAPR International Conference on Pattern Recognition (ICPR), ACM International Conference on Knowledge Management (CIKM), IEEE COMPSAC, and ACM KDD Knowledge Discovery and Data Mining Conferences and recently Chaired the Big Data Track at IEEE COMPSAC 2012 in Kyoto. She is a Senior Member of the ACM and a Member of the Editorial Board of the Communications of the ACM.

Prior to joining IBM she worked at Lawrence Berkeley Laboratories as an undergraduate and graduate student intern in the biochemistry and math/physics divisions and as a Teaching Assistant/Grader for the Chemistry, Astronomy, and Mathematics Departments at the Graduate School of Arts & Sciences of Harvard University and the College of Letters and Sciences at the University of California at Berkeley.
