Summary

* ***** ********** ** **********/Data science/Machine learning applications in pre- dictive analysis.

Self-starter, passionate learner, experienced working on diverse domains.Trained in data scrapping, wrangling, feature engineering, training models, cross-validation, reg- ularization, model optimization in Python, scaling in Spark, querying in SQL.

Strong organizational, leadership and communication skills. Mentor and teach courses to students from diverse background. Designed course curriculum with hands-on exercises, which ensued increased student participation and good feedback. Projects (coding in Python, Spark, R, Matlab)

Exposure studies: Temporal trend’s variation of phthalate biomarker concentra- tions, with respect to physical and socio-demographic factors of women, using multivariate regression models in R, Matlab.Paper presented at ISES-ISIAQ 2019, Lithuania.

Health exposure study: Statistical modeling to predict and compare the risk of exposed group living near mines and control group living away from mines. Published chapter in book

Used Random Forest on ApacheSpark to scale big healthcare datasets, predicting customer churn on hospital admissions, for mental or physical health problems, based on diverse socio-demographic parameters.

Developed Image classi cation technique using particle’s form factors, to correlate an- thropogenic input across di erent lake cores.Conference paper at AGU, 2019, San Francisco

Developed multi-layer perceptron neural network for classifying regions of prof- itable oil production, based on di erent input borehole parameters, for UK-CS basin

Experienced in NLP- Developed machine learning model for classi cation of text from humans and from machines. Word Cloud maps for feedback survey data through period of 8 years for temporal variation in Sentiment analysis

Employed K-means clustering to segment neighborhoods based on venue preference of public transits, public places, private restaurants etc, for exploratory BI

Used LSTM neural network for Time-Series forecasting used to predict future stock prices and alpha, beta risk patterns

Spatial imagery analysis and tracing of surface lineaments from Digital elevation models in ArcGIS.Conference paper at IGU 2013
