Education:
Ph.D., Colorado, 1983
Research Interests:
Professor Haan has professional interests
in theoretical atomic physics and in elementary-school science education.
He is interested in photoionization--in which laser light removes electrons
from atoms--and in the reverse process of photorecombination. Most recently
he has been doing computer modeling of double ionization of atoms by intense
laser light. He has received continuous NSF support for his research since
1986, and has involved students since 1987. Professor Haan also spends
professional time working in K-8 science education, and much of his teaching
is in elementary-education science courses.
