Finally, our seminar instructors possess superior communication skills and excel at conveying technical information to non-statisticians.

Allise Wachs, Ph.D.

Allise WachsDr. Wachs has 20 years of experience in the application of statistical methods to optimize product designs and manufacturing processes—and to assess product liability risk. Her research includes the development of mathematical models to reveal optimal decision sequences. She is the President of Integral Concepts, Inc. where she assists engineers and scientists in the application of statistical and optimization methods to reduce the time and cost to develop new products. She also helps to resolve complex engineering and manufacturing problems quickly and thoroughly.

Her areas of expertise include designed experimentation, reliability analysis, general statistical methods, statistical process control, measurement system assessment, and stochastic optimization. She has been an adjunct professor in the College of Engineering at the University of Michigan, and she provides expert testimony in product liability litigation.
