• Build process simulation model to identify optimal critical process path using both chaotic dynamic and stochastic process simulation such as Hidden Gauss-Markov and Monte-Carlo Simulation. 
• Develop anomaly detection models such as iForest, Local Outlier Factor, GMM, one class SVM, etc. to identify anomalous behavior in critical process inputs for both batch and stream processing. 
• Manage machine learning model life cycle through documentation, version control, model presentation, model audit, back testing, forward testing, benchmarking with the help of performance metrics. 
• Communicate and democratize model findings very clearly and precisely with stakeholders such as market leads, metallurgists, R&D and senior business leaders.   
• Drive the collection, cleansing, processing, and analysis of new and existing data sources 
• Report findings through appropriate outputs and visualizations tailored for the intended audiences 
• Learn and stay current on analytics developments in one or more business domains: Internet of Things, Manufacturing, Supply Chain, Forecasting, Marketing and Sales, Pricing, etc. 
• Learn and stay current on developments in one or more analytics domains: Operations Research, Machine Learning, Deep Learning / AI, Simulation, etc.  
• Generate innovative ideas, establish new research directions, and shape the information strategy in support of technical projects and new product developments 
• Collaborate with new, cross-functional teams on accelerated projects to scale data architecture, build digital products, and execute data science solutions 
• Perform all other duties and special projects as assigned.
