Current Projects

Mechanistic Machine Learning
Advisor: Lena Mamykina, MS, PhD
The overarching goal of this research is to develop new approaches to facilitating clinical reasoning and decision-making through aligning clinicians’ cognitive models of patients’ pathophysiology, mechanistic models of human physiology, and empirical patient data. Reconciling differences between cognitive and mechanistic models requires deep understanding of medical cognition and clinical work, novel computational modeling, and innovative co-design approaches that will bring together cognitive scientists, data scientists, and experts in human-computer interaction and clinical decision support.

Differences in Presentation and Treatment of Acute Myocardial Infarction based on Gender and Race/Ethnicity
Advisor: Noémie Elhadad, PhD
We aim to measure and characterize differences in presentation and treatment of acute myocardial infarction (AMI) using structured electronic health record data and free-text from clinical notes. We are using empirical distributional semantics methods (e.g., word2vec and GloVe) to identify potential biases and empirical associations based on demographics. We are also analyzing clinical notes over time prior to and after initial diagnosis to understand differences in the trajectories of sign or symptom documentation for patients, lengths of time to treatment, and resulting impact on patient outcomes.

Recognizing and Normalizing Condition Concepts with Severity Modifiers
Advisor: Chunhua Weng, PhD
The presence of qualifiers such as severity or disease stage complicate the recognition and normalization of biomedical concepts from free text. A single concept can often be mapped to a terminology in multiple ways. Our problem is motivated by inconsistent recognition of disease conditions in Criteria2Query (C2Q), a tool for exploring clinical trial inclusion and exclusion criteria. We are developing a novel two-step, ontology-aware mapping scheme that is optimized for extracting disease concepts at a high level of specificity.
