My wife, Hennie Nijland, was born in Holland, and has lived in California with me since 1981. She teaches third grade, plays the flute, enjoys hiking, reading, and classical music, and is a good cook, conversationalist, and companion.

Daughter Amanda, born May 24, 1981, graduated from MIT in 2003, with a B.S. in Mathematics with Computer Science. She worked in Stuttgart, Germany, in summer 2001, in a Bosch research lab, on numerical fluid mechanics. In summers 2002 and 2003, she was a counselor at the PROMYS math progam for gifted high school students, which allowed her to stay in Boston. In fall 2003, she moved to La Jolla and began working towards a Ph. D. in mathematics at the University of California, San Diego. She is working on a Ph. D. thesis in number theory. You can visit Amanda's web site at UCSD. She enjoys surfing, photography, glassblowing, and the violin. She plans to complete her Ph. D. in 2009 and has accepted a job teaching mathematics at Williams College, starting in August, 2009.

Daughter Helen, born July 18, 1984, graduated from UC Berkeley in May, 2007, with a degree in Integrative Biology. She then worked until Januray, 2009, as a botanist for Stillwater Sciences, whose head office is in Berkeley, but Helen often worked in the country. She enjoys photography, backpacking, and jumping off cliffs into water. She is full of life and fun, and believes in living life enthusiastically. The photo you see here is her high-school graduation picture, taken in early 2002. She and her friend Lauren are (as of April 2009) traveling in India for four months.
