• Developed a quarterly forecast model to predict sales of Tableau using a probabilistic time-series model GluonTS hosted on AWS Sagemaker, which improved error by 10% as compared to existing models
• Created a model factory (generating 50+ unique models) using DataRobot to provide guidance on territory evaluation during the annual sales planning process, speeding up time to decision by 2x
• Prototyped a discounting model to provide recommendations for optimal discount on a given deal based on account history and deal size. Additionally, the model predicts likelihood of a deal to be won and key features.

• Detected and quantified anomalies in time series of surface displacements measured via GPS using a variety of techniques including Principal Component Analysis and Kalman filtering in MATLAB and Python.
• Modeled tectonic plate motion using GPS surface displacements and a combination of linear regression and Tikhonov regularization.
• Quantified biases introduced by hyperparameters in the filtering method by performing sensitivity tests.
• Implemented a density-clustering algorithm DBSCAN to automatically create a catalog of tiny earthquake locations.
• Increased the signal to noise ratio of small GPS signals by stacking time series and performed common mode filtering to remove large regional biases in spatial data.
