Data Analyst

Chicago, United States


Much of my past data analysis experiences have been in academia, so I am well-versed in independent learning and producing professional results. With more than six years' worth of Python experience, I'm always trying to learn the latest packages pertaining to my research interests. After graduating with my MS degree in Applied Math with a Statistics concentration, my new focus is programming to solve problems in machine learning and probabilistic modeling.

Favorite Python Packages:

Pandas, TensorFlow, numpy, matplotlib, sklearn, networkx
