Po-Hao Chen, MD MBA



Po-Hao Chen (Howard Chen) is a musculoskeletal radiologist and the Associate Imaging Informatics Officer at the Cleveland Clinic Main Campus. He is also the director of the CC Imaging Data Science Center and chairs the Imaging Institute's AI Advisory Council. Dr. Chen received his MD and MBA from Harvard University in 2012. After finishing his diagnostic and nuclear radiology residency, he underwent fellowship training in clinical imaging informatics and musculoskeletal radiology, all at the Hospital of the University of Pennsylvania. He was a finalist in an innovation challenge sponsored by UPenn, and some of his prior projects were supported by Microsoft Research and some by the Microsoft BizSpark program. He has published in imaging informatics, machine learning, and radiology process improvement.

You can find his profile on Twitter, LinkedIn, Google+, or follow the blog Figure Stuff Out. He is also the creator of Radiology Data Quest, a data science blog focused on radiology. Howard enjoys imaging informatics, healthcare innovation, and good comfort food. The content of this website and his blog are of Howard's personal opinion and does not represent the view of the Cleveland Clinic.

  • 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.
  • 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.

  • 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
