John Liechty

Professor of Marketing and Statistics
John Liechty


John Liechty is a Professor of Marketing and Statistics at Penn State.

Liechty received his Ph.D. in Mathematical Statistics from the University of Cambridge in 1998. He received his MS in Statistics from Brigham Young University in 1993, and his BS in Applied Physics from Brigham Young University in 1991.

Most of his research is divided between developing statistical methods and models and applying these methods to problems in Marketing and Finance. In Marketing, he has made important contributions by providing methods that help improve the quality of data coming from marketing research studies. In Finance, Liechty has made contributions with regards to both providing better mathematical methods for approximating the price of options, assuming a complex underlying stochastic price process, as well as creating models that provide better asset allocation (e.g. better strategies for purchasing and holding stocks). In Statistics, he has focused on Markov Chain Monte Carlo approaches to inference, and on selectively reducing the size of a dataset while maintaining a high level of the information content. Liechty's recent work has focused on issues related to broader problems in society. Some of this led to establishing better data and analytic capacities for the U.S. Financial regulatory infrastructure. Future work will focus on how society can best organize capital to produce public goods; finding incentive aligned approaches to both reduce Health Care costs; and model large scale (distributional) phenomics based on the geometric structure of the biology of life as revealed through high-resolution images.
