  - Developed NLP-based approaches to detect medically-relevant events from clinical notes. Applied neural networks implemented in Keras and feature engineering using XGBoost of concepts extracted from unstructured English text. - Work resulted in models with superior detecting power (sensitivity 0.87, PPV >0.3) to manual review by nurses. - Developed NLP-based approaches to detect medically-relevant events from clinical notes.

  - Built a corpus of annotated operation notes for use in classifying surgeries based on quality of outcome. Developed an applet in JavaScript that facilitated fast annotation by physicians of notes at the word and sentence level for positive-negative sentiment. - Trained neural networks on corpus and demonstrated superior loss minimization during learning to networks trained on domain-nonspecific sentiment corpora. - Built a corpus of annotated operation notes for use in classifying surgeries based on quality of outcome.
