Eyal Rozenman is currently a member in the Institute for Advanced Study, Princeton. He grew up near Tel Aviv, Israel, went to Tel Aviv University for his B.Sc. degree, and received his Ph.D. from the Hebrew University under the guidance of Nathan Linial. Eyal's research interests include groups, expanders, and their interaction, and pseudorandomness in general. He loves to read and write papers which are elementary, but he likes them better if they contain fancy mathematical notions. Eyal's non-research interests include hiking, reading, and avoiding driving.

Aner Shalev was born in the previous century in a kibbutz on the sea of Galilee. His first love (at 10) was experimental chemistry, which proved too dangerous when a test tube full of hydrogen exploded in his hands. He wisely moved to pure mathematics and writing fiction.

In 1988 he finished his Ph. D. in mathematics at the Hebrew University of Jerusalem, supervised by Shimshon Amitsur and Avinoam Mann, and published his first book, Opus 1 - a collection of stories with a musical structure. Other literary works followed: Overtures (1996) - seventy openings of stories without ends, and the recent novel Dark Matter (2004), a complex love story with astrophysical parallels, alternating between prose and email, which will also appear in some European languages.

The mathematical work of Aner Shalev is in algebra. He enjoys studying groups using other disciplines, such as Lie methods and probabilistic methods. He was an invited ICM speaker (1998), and chaired the Institute of Mathematics at the Hebrew University (1999-2001). He used to enjoy playing chess with his daughter Ariella until he started losing.

Avi Wigderson was born in Haifa, Israel in 1956, and received his Ph. D. in 1983 at Princeton University, under Dick Lipton. He enjoys and is fascinated with studying the power and limits of efficient computation, and the remarkable impacts of this field on understanding our world. Avi's other major source of fascination and joy are his three kids, Eyal, Einat and Yuval.
