I have a Bachelor’s degree in Physics with a minor in Mathematics. I have over sixteen years’ experience industry with substantial experience performing mathematical, and statistical modeling of various physical processes. This experience has enabled me to gain diverse operational experience in several different nvironments. Most notably, ARIMA time series analysis and forecasting, various regression methods, uncertainty analysis, pattern detection using smoothing kernel estimation, correlation analysis, stochastic process modeling, and others. In addition, strong programming expertise in R and associated tools such as Rstudio,
Shiny, and multiple R libraries.
