About

About

I have passion for translating cutting-edge technology into everyday patient care. At the heart of my work is a commitment to leveraging artificial intelligence and data engineering to make diagnostic services more available, accessible, and affordable.

In my current roles as Vice Chair of Artificial Intelligence for Diagnostics Institute and Medical Director for Enterprise Radiology Informatics at Cleveland Clinic, we built the Center for Intelligent Diagnostics, focusing on the translational application AI to revolutionize diagnostics and treatment planning. In my previous role as the Chief Informatics Officer for Imaging, Cleveland Clinic modernized IT systems for four new hospital acquisitions and replaced radiology PACS for the enterprise's 4 million imaging exams yearly.

Volunteering in leadership roles across key organizations has been among my most fulfilling experiences for advancing healthcare technology integration. At the ACR, I've championed AI in radiology and cybersecurity efforts through the Informatics Advisory Council and Commission on Informatics. Leading SIIM's Security Subcommittee, I've tackled healthcare cybersecurity intersections. At the RSNA, I contribute to radiology future through the Informatics Policy Committee, and as SPIE's Healthcare Informatics Program Committee past chair, I've spurred innovation. These positions have fueled my growth and impact in the field.

My research endeavors have culminated in authorship in over 70 publications in prestigious journals, abstracts, presentations, posters, and book chapters, across imaging informatics, AI, genomics, and beyond. My innovations have been recognized with a USPTO patent for an AI algorithm in CT imaging.

You can find my profile on Twitter, LinkedIn, or follow the blog Figure Stuff Out. 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.

Research Projects

Natural Language Processing for Imaging Protocols

  • Presented at SIIM 2020 and published in Journal of Digital Imaging in 2022.
  • Won New Investigator Award
  • Protocols are "instruction sets" for radiology modalities. Proper protocol assignment is time consuming, but wrong protocols cause delayed care or incorrect care.
  • Comparing commercial auto ML builders (Google AutoML), with models using random forest, boosted trees, and deep learning approaches (e.g. ULMFiT).

    • AI for Acute Aortic Syndrome Detection

  • Algorithm combines deep learning, physics, and expert insight to expedite high accuracy detection of aortic dissection detection on chest CTA.
  • Patent-pending.
  • Acute aortic syndrome has 1-3% mortality per hour over the first 24 hours. Prompt detection saves lives.
  • Integration with radiology PACS and RIS for workflow enhancement.

    • 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

    • ARIES - Deep Learning + Bayesian System for Radiology Education and Dx Support

  • Plug-and-play Bayesian "artificial intelligence" for diagnostic support and education, with real-time update of differential diagnoses.
  • Approach validated in 2021 article as a high accuracy, explanable system for education.
  • Various features presented at 2016 SPIE Medical Imaging and 2018 SPIE Medical Imaging conferences
  • 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 open-source release. Not a commercial product

    • 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.

    • 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
