Kent M. Eskridge

Areas of Expertise: Design of Experiments, Biological modeling, Statistical consulting

Research Interests:
Design of Experiments:  I am interested in the design and analysis of experiments. Recently I have been most interested in the properties and applications of (1) supersaturated split-plot designs and (2) confounded factorial conjoint choice experiments in consumer preference. I am also quite interested in working with researchers in other disciplines in developing and applying new ideas of design and analysis to their research. My most recent teaching duties in this area are (1) Advanced Design of Experiments (Stat 902) and (2) Theory of Design of Experiments (Stat 904).

Biological modeling:  I am interested in development of statistical and mathematical approaches in modeling complex biological systems. Recently I have been most interested in the properties and applications of (1) spline-enhanced differential equations as applied to pharmacokinetics and pharmacokinetics and (2)  structural equation modeling as applied to composite interval gene mapping and in the analysis of gene-environment interaction. My most recent teaching duties in this area are (1) Applied Multivariate (Stat 873) Statistics and (2) Theory of Multivariate Statistics (Stat 973).

Statistical consulting:  I aid researchers from a wide range of fields with the design and analysis of their experiments. The majority of work is in the biological sciences.
