He has made significant contributions to the field of multivariate statistical analysis, particularly in the context of gas chromatography and mass spectroscopy. With a total of 3 patents to his name, Kotula's work has advanced the methodologies used in analyzing complex data sets.

Latest Patents

Kotula's latest patents include a "Method for factor analysis of GC/MS data" and a "Method of multivariate spectral analysis." The first patent provides a fast, robust, and automated multivariate statistical analysis of gas chromatography/mass spectroscopy (GC/MS) data sets. This method involves the systematic elimination of undesired, saturated peak masses to yield data that follow a linear, additive model. The cleaned data can then be subjected to a combination of Principal Component Analysis (PCA) and orthogonal factor rotation, followed by refinement with Multivariate Curve Resolution-Alternating Least Squares (MCR-ALS) to yield highly interpretable results.

The second patent outlines a method for determining the properties of a sample from measured spectral data collected from the sample. This method includes generating a two-dimensional matrix containing measured spectral data, providing a weighted spectral data matrix, and factoring it into the product of two matrices through constrained alternating least-squares analysis. This innovative approach can be applied to analyze X-ray spectral data generated by operating a Scanning Electron Microscope (SEM) with an attached Energy Dispersive Spectrometer (EDS).
