About

About

I am the Chief Informatics Officer at the Cleveland Clinic (CC) Imaging Institute and the Medical Director of Enterprise Radiology Informatics at Cleveland Clinic. In addition, I practice musculoskeletal radiology at the Imaging Institute. After receiving an M.D. and M.B.A. from Harvard University in 2012, I completed diagnostic radiology, nuclear medicine, MSK imaging, and informatics training at University of Pennsylvania.

Currently, I chair the American College of Radiology (ACR) Informatics Advisory Council and the Data Science Summit and am an ACR Commission on Informatics member. For SIIM Cybersecurity subcommittee, I serve as the chair. For the Radiologic Society of North America (RSNA), I am the incoming Vice Chair for Informatics Policy starting December, 2021 and a course director for the AI Implementation Spotlight Course.

My current scholarly focus is on reducing data bias and algorithmic brittleness by assessing and building imaging datasets and using cases to standardize the quality of machine learning models. For cybersecurity, my work focuses on radiology technical and operational preparedness and recovery in the context of evolving cyber threat.

You can find my profile on Twitter, LinkedIn, or follow the blog Figure Stuff Out. I am also the creator of Radiology Data Quest, a data science blog focused on radiology. I enjoy imaging informatics, healthcare innovation, and good comfort food. The content of this website and the blog are of my personal opinion and do not represent the view of Cleveland Clinic.

Projects

Natural Language Processing for Imaging Protocols

  • With Cleveland Clinic radiology resident Brian Xavier. Presenting at SIIM 2020.
  • Won New Investigator Award
  • Protocols are instruction sets for radiology modalities
  • Comparing commercial auto ML builders (Google AutoML) and manual workflows
  • Integrated Workflow Peer Learning Case Submission

  • Collaboration with Cleveland Clinic Imaging Quality. Presenting at SIIM 2020.
  • Peer Learning is the new form of Peer Review - Higher specificity for learning opportunities. Allow people to submit best cases in a nonthreatening way.
  • Voluntary case submission is the biggest problem.
  • Created a plugin for the PACS viewer - integrated case submission workflow without interruption and with auto-population of MRN and Accession.
  • Demonstrates substantially increased submission rates relative to old workflow
  • 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.
  • Published in 2019 JACR article
  • 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.
  • 2017 AUR Research Scholars award for oral presentation.
  • ARIES - Web-Based Bayesian Analytics for Diagnostic Support

  • Plug-and-play Bayesian "artificial intelligence" for diagnostic support and education, with real-time update of differential diagnoses.

  • Contributed to Bayes net research leading to additional oral presentations at ASNR, ACR, and SIIM.
  • Supported in part by an RSNA Educational grant with 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 manuscripts 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)
  • Trains perception of normal versus abnormal features.
  • 2 oral presentations at the RSNA conference.
  • Peer-reviewed manuscript showing improved trainee ability to perceive abnormality after one 20-minute session.
  • Integrating natural language processing and machine learning algorithms to categorize oncologic response in radiology reports

  • Created 9400 manually curated reports using structured reporting system "Code Oncology."
  • Studied the effect of NLP techniques (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 multiple machine learning algorithms on predictive accuracy.
  • Peer-reviewed manuscript published.
  • Unsupervised genomic and epigenetic analysis

  • Developed new techniques for probabilistic modeling of epigenetic relationships between miRNA, mRNA, and DNA polymorphism using differences between patient samples to bypass need for a priori data annotation.
  • Predictions validated by biochemical bench analysis.
  • Technique utilized in manuscripts published Science, Cell, Molecular Cell, and BMC Genomics.
  • Select Publications
