Matt Wheeler, Ph.D., is a staff scientist that develops statistical models for dose-response analysis and novel Bayesian non-parametric methodologies. His research includes methodological, applied and translational components. As a biostatistician, he develops novel methodologies from applied problems seen in a wide array environmental health data. The translational component flows from the concept of findability, accessibility, interoperability, and reusability (FAIR) in science. Here Dr. Wheeler’s researches and develops software platforms enabling other scientists’ easier access to his methods research. This also allows reproducibility of applied research problems.
- BMDS 3.x / ToxicR
This is the premiere dose-response software for dose-response analysis. Dr. Wheeler wrote the dichotomous and continuous module subroutines, which includes the Bayesian model averaging components. Currently ToxicR is under active development to include all of the functionality of BMDS in R as well as utilize common routines used by the National Toxicology Program.
This software is under active development and was used in “The COVID-19 pandemic vulnerability index (PVI) dashboard: monitoring county level vulnerability.” It builds upon the work of K Moran to approximate Gaussian Process regression within machine precision. Here all computations are near linear as opposed to the traditional cubic time complexity seen in Gaussian Process regression.
