Some academic and mathematical indices:

h-index: A researcher is said to have h-index N if they have written N papers that have been cited at least N times. My h-index is 59. (Jens Palsbergh maintains a list of Computer Scientists with h-numbers 40 or more.)

Other indices and citation counts: My google scholar page with other indices is at ( includes other indices such as the i10-index)

Erdos Number: The Erdos number of a mathematician is a measure of the "collaboration distance" from the mathematician Paul Erdos. People that have co-authored papers with him have Erdos number 1. My Erdos number is 2 via a paper I co-authored with Ron and Fan Graham. (The Erdos Project maintains a list, I am listed under Ron Graham.)

Acaademic Lineage: Mathematicians and theoretical computer scientists trace their family tree with their advisor as their parent. The Mathematics Genealogy Project traces my lineage via Nancy Lynch to Hartley Rogers, Alonzo Church, Oswald Veblen, E.H. Moore, Simeon Poisson, and Joseph Lagrange. They go even further and with some fudging (since Lagrange never wrote a thesis) reach Euler, the Bernoullis, and finally Leibniz himself. A number of CS professors share the connection to Church.
