1970

He was a Putnam Fellow at MIT in 1970.

1972

He completed an S.B. and S.M. in Mathematics at the Massachusetts Institute of Technology in 1972.

The title of his thesis was "Evaluation of certain character sums".

1974

He received his Ph.D. in Mathematics from MIT for his thesis "The 4-part of the class group of a quadratic field", in 1974.

His advisor for both his masters and Ph.D was Harold Stark.

In 1974, he joined AT&T Bell Laboratories and eventually became a member of technical staff.

2004

In 2004, he moved to the University of Michigan as a professor of mathematics.

Lagarias originally worked in analytic algebraic number theory.

His later work has been in theoretical computer science.

Lagarias discovered an elementary problem that is equivalent to the Riemann hypothesis, namely whether

for all n > 0, we have

with equality only when n = 1.

Here Hn is the nth harmonic number, the sum of the reciprocals of the first n positive integers, and σ(n) is the divisor function, the sum of the positive divisors of n.

He disproved Keller's conjecture in dimensions at least 10.

Lagarias has also done work on the Collatz conjecture and Li's criterion and has written several highly cited papers in symbolic computation with Dave Bayer.

2012
