Chemometric Workflow for Forensic Investigations
Chemistry Matters’ Mike Dereviankin and Dr. Court Sandau will be teaching a short course at Pittcon 2021. The one day course, Data Analytics and Statistics in Quantitative Chemical Analysis – Chemometric Workflow for Forensic Investigations, is targeted to intermediate data scientists interpreting complex quantitative chemical data sets. This course will also provide unique approaches to using modern programming languages and workflows to organize the workflow of their data analytics. Possible attendees include students, researchers, industry scientists, and data science consultants.
The rapid advancement and increased ability to resolve chemical components has superseded the common procedures for forensic data analysis. Chemometrics is a disciplined blended in data science that aims to efficiently extract information from the expanding inventory of measurable chemicals. A methodological workflow rooted in big predictive analytics will be presented for statistically modelling changes in complex collected chemical data for applications in forensic consulting. After completion of this course, attendees will gain familiarity with concepts involving data pre-processing, statistical correlation, and multivariant statistical analysis. Case studies will be presented for the application of modern data science computer science techniques and creating supporting visuals using R and Python programming.
