Projects

ARIES - Web-Based Bayesian Analytics for Diagnostic Support

  • Plug-and-play Bayesian network decision support with real-time update of differential diagnoses
  • Clinical mode presented at 2016 SPIE Medical Imaging conference
  • Educational mode presented at 2016 RSNA annual conference
  • Contributed to Bayes net research leading to additional oral presentations at ASNR, ACR, and SIIM.
  • Supported in part by an RSNA Educational grant with plan for open source release. Not a commercial product
  • Capricorn - Radiology Residency Analytics Tool

  • Residents: Track cases automatically for ACGME and MQSA. Discover discrepancies. Review attending changes to preliminary report. Crowdsource teaching files. (website)
  • Program Director: Curate resident performance dashboards. Identify great calls. Recognize underperformers.
  • Decreased missed PE on CTA by trainees using data-driven integrated quality improvement initiative
  • 2 peer-reviewed manuscript on usability and on statistical analysis of attending variability.
  • RSNA oral presentations on analytics and approach to crowd-sourcing teaching files.
  • Winner of the 2014 Open Source Leadership Award at SIIM. Not a commercial product.
  • Centaur - Rapid-Fire Learning Module for Basic Imaging Findings

  • Radiology education tool. Single player "video game"-like mechanics. Rapid fire cases. Instant feedback. (website)
  • Focuses on perception of normal versus abnormal features.
  • Module engine behind 2 oral presentations at the RSNA conference.
  • Peer-reviewed manuscript showing improved trainee ability to perceive abnormality after one 20-minute session.
  • RadCare - Resident-Led Radiology Consultation for General Medicine Wards

  • Created in-person consultation service for radiology residents to integrate with general medicine teams as part of normal radiology rotation.
  • 43% of all consultations led to a change in immediate clinical management decisions.
  • Radiology residents were shown to be no less productive while on consultation compared to in reading room.
  • Received 2017 AUR Research Scholars award for oral presentation.
  • Integrating natural language processing and machine learning algorithms to categorize oncologic response in radiology reports

  • Collected 9400 manually curated reports using "Code Oncology," structured reporting system at Penn Medicine.
  • Studied the effect of filter-based feature selection, N-gram tokenization, stop-word removal, word stemming, and tokenization models such as TF-IDF on classification accuracy.
  • Compared performance of 5 machine learning algorithms such as support vector machine, Bayes machine, and random decision forests.
  • Manuscript submitted.
  • Select Publications
