Raised in Germany and in Ethiopia, Dr. Hasselblatt came to the US on a Fulbright Scholarship. Since earning a Ph.D. from Caltech, he has been a Professor of Mathematics at Tufts, with occasional research appointments in Marseille, Paris, Tokyo and Zürich. He publishes extensively and has served as Department Chair and as Associate Provost of the University. Born on the North Sea coast, his travels as lecturer, researcher, singer, tourist, and faculty host have taken him from 66˚ North to 55˚ south: to Africa, Asia, the Middle East, the Americas, and across Europe. On this trip he will discuss how language, religion and migrations divide and connect the parts of this region and other areas of Europe.
