Varian Medical Systems, Data Science Intern Palo Alto, CA May 2017 - Sept 2017

• Achieved an accuracy of 78% by predicting the volume of voids in ‘Targets’ using statistical modelling and Machine Learning techniques to prevent damage to the ion chamber.

• Improved accuracy of MLC leaves to 0.01 mm by using (image recognition) object detection techniques R- CNN, Fast R-CNN in Tensorflow (Python).

• Mined massive amounts of data (~500 GB) and performed large-scale data analysis to derive useful production/engineering insights into the product behavior and present it to a non-technical audience.

• Analyzed different machines quantitatively and qualitatively by plotting patterns (data visualization) of their usage using ggplot2 to understand their respective behavior. Northeastern University, Teaching Assistant (Statistics) Boston, MA Sept 2017 - Present

• Guided a class of 44 students during tutoring hours; graded assignments, quizzes in a timely manner.

• Explained several topics in Descriptive Statistics, Inferential Statistics and Probability (Probability Distributions, Hypothesis Testing, Multiple Linear Regression, ANOVA). Projects
