Research

The Artificial Intelligence Lab at Brown University’s Center for Biomedical Informatics works on a wide range of problems in clinical data science. Our goal is to develop machine learning techniques to assist clinical decision making, avoid medical errors and ultimately improve patient health. Some key directions of interest include:

  • Clinical Text Mining
  • Patient-centric Information Retrieval
  • Biomedical Text Understanding and Summarization
  • Diagnostic Assistance
  • Clinical Event Forecasting
  • Data-driven Prognostics
  • Precision Medicine
  • Human Computation

Precision Medicine

Speeding Up Biobanks with Approximate Data Structures

Biobanks store considerable volumes of read data, often represented in exact data structures. While storage-efficient, these structures are sub-optimal for retrieval purposes. Instead, we develop probabilistic approximate data structures such as Bloom filters and graph sketches to speed up retrieval times by several orders of magnitude.

Postoperative Care

Forecasting Complications in Intensive Care with Deep Neural Networks

The flood of concurrently incoming signals generated in intensive care environments goes well beyond the parallel reasoning capacities of the human brain. In order to ensure high quality of care as well as timely decision support, we develop machine learning techniques to forecast the likelihood of intensive care patients to develop post-surgical complications.

Representation Learning for Geo-Spatial Data

Many social network applications depend on robust representations of spatio-temporal data. This project establishes an embedding model based on feed-forward neural networks which transform social media check-ins into dense feature vectors encoding geographic, temporal, and functional aspects for modeling users, places, and entire neighborhoods.
