Experience

Machine Learning Researcher - Chevron Center of Research, Texas A&M University (TAMU), 9/2020 – 5/2021
• Developed a scalable method for lithofacies identification from well log data using unsupervised models (KMeans, Hierarchical
clustering). Assessed model performance using intrinsic metrics like silhouette score, Davies-Bouldin Index, Dunn Index.
• Reduced processing time by 15 minutes per well by building an automated data consolidation workflow to integrate log, well
inventory and surface topography data for approximately 200 wells.

Graduate Research Assistant - Texas A&M University (TAMU), 8/2019 – 8/2020
• Designed 2 novel statistical metrics for quantification of 3-D fluid connectivity during various Enhanced Oil Recovery (EOR) stages
for a dataset of 4050 HI-RES µCT images of carbonate core. The metrics exhibit correlation coefficient >0.8 for all stages.

Graduate Research Assistant - University of Oklahoma, 8/2018 – 8/2019
• Programmed scalable supervised learning models for image segmentation of SEM maps of organic-rich shales into 4 solid
components with an accuracy of ~95%. Evaluated model performance using precision, recall, F1, confusion matrix & ROC curve.
• Engineered 16 features to be extracted from the SEM image data to build a robust model for segmentation (Random Forest).
• Improved the performance of the classification model by 16% by implementing hyperparameter optimization methods.

Research Intern (solar cell) - Indian Institute of Engineering Science & Technology, Shibpur (IIEST), 1/2018 – 4/2018
