My Work Experience

Where I've interned and worked during my career.

Medtronic | Jan 2020 - Present

Senior Principal Data Scientist

Support development, validation, and transfer to manufacturing of micro- fabricated glucose biosensors with machine learning and predictive modeling. • Apply machine learning to model the relationship between sensor signals and process variables. Select the best models among linear, kernel ridge, support vector machines, nearest neighbors, Gaussian process, decision trees, multiclass and multioutput, neural network, and ensemble method algorithms. • Organize integrated DOEs to generate data for predictive modeling. • Work with the algorithm team in modeling the relationship between sensor output and body glucose levels. • Coach engineers on statistics and Six Sigma. • Work with manufacturing to transfer R&D technology to manufacturing.

Hexion Inc. | Jan 2014 - Jan 2020

Business Analytics Manager

Pioneered machine learning to improve business performance. Trained and coached engineers on advanced statistics. Conducted extensive data analytics and machine learning for product and process improvement. • Led a machine learning H.R. project to reduce employee churn. • Instituted machine learning for supply chain analytics, sentiment analysis on customer surveys, market segmentation, and financial forecasting. • Trained 38 scientists and engineers on advanced statistics. Taught and mentored dozens of Six Sigma belts and certified eight belts. Prepared the training materials. • Improved quality and won back an $8MM customer. Identified key independent variables using machine learning techniques such as regression and multivariate analyses and reduced variation to improve product quality. • Led multiple product development projects and successfully launched five new epoxy and phenolic products that generated $3.2MM in revenues. Used statistical techniques such as MSA, process capability analysis, hypothesis testing, regressions, DOE, and control charts to ensure project success.
