Lorrie received her Ph.D. from the University of Iowa in 1981.

A perpetual student of college and life, Lorrie has put in time at many institutions of higher education and has seen alot of the world (mostly FIRST CLASS, having worked for the airlines) and has sampled a varied menu of employment options. She likes to get the word out about new discoveries via publications in the area of statistical theory and applications. Check out the next conference she is speaking at. Lorrie puts lots of novel course notes and stuff on the web. Check out some of the people you can meet .

Education

Educated in the hotbed of statistical excellence - the Midwest at Moraine Valley Community College; Chicago State University; Western Illinois University; University of Illinois and University of Iowa

Employment

As for the school of hard-knocks (also known as the real world), gainful employment occured at such prestigious places as Illinois State Water Survey (counting raindrops); University of Illinois Research Resources Center (analyzing comfort levels of various positions for birthing mothers); TransWorld Airlines (keeping those hard drives spinning for the travel agents); United Airlines (efficiently getting those food trucks to your planes); AT&T (learning the difference between EPROM and RAM), at the illustrious (can't beat the weather) institution called University of Central Florida and now at Armstrong Atlantic State University  in historic Savannah, Georgia.
