Summary
Before moving into cloud and AI product leadership, I spent a decade building patient-specific computational models of the heart from medical images - at Siemens Corporate Research in Princeton and Erlangen, and as a doctoral researcher at the Technical University of Munich.
The research question was consistently the same one: can a learned model stand in for a trusted physical computation, in a setting where being wrong is not an option? Clinicians and regulators were the audience then. The same question now sits under every discussion of physics-informed AI and simulation surrogates.
The arc runs through five connected threads:
- Patient-specific anatomical models of the complete valvular apparatus - aortic, mitral, tricuspid and pulmonary valves - estimated automatically from 4D CT, transesophageal echocardiography and MRI, covering a wide spectrum of morphological, dynamic and pathological variation.
- Physics-based simulation on top of those models: computational fluid dynamics for whole heart haemodynamics and paediatric cardiology, finite-element biomechanics of the mitral valve and subvalvular apparatus, and patient-specific material property estimation.
- Validation against physical measurement - non-invasive haemodynamic assessment of aortic coarctation validated against invasive in vivo catheter measurements, and treatment outcome prediction with clinical follow-up.
- Learned surrogates replacing iterative fits - regression-based 4D surface reconstruction and learned discriminative distance functions in place of optimisation loops.
- Synthetic-to-real transfer, demonstrated twice independently: training a device localiser entirely on synthetically rendered data and closing the domain gap to real fluoroscopy with unlabelled images and instance weighting.
The work translated into product. The valve modelling and detection methods underpin Siemens Healthineers heart-valve software, and the surgical planning line was recognised with the Thomas Edison Patent Award for System for Planning Heart Valve Surgery (Princeton, November 2015). Nine granted patents name me as an inventor.

- ~1,233-1,347 citations; h-index 19-20; i10-index 29. (OpenAlex: 1,233 / h 19 / i10 29. Semantic Scholar: 1,347 / h 20. The two indexes count venue duplicates differently.)
- Most-cited work: Patient-Specific Modeling and Quantification of the Aortic and Mitral Valves From 4-D Cardiac CT and TEE, IEEE Transactions on Medical Imaging, 2010 - 194-211 citations, first author.

- Doctorate: Patient-specific Modeling and Quantification of the Heart Valves from Multimodal Cardiac Images, Technical University of Munich, Faculty of Informatics - submitted 30 June 2010, accepted 28 September 2010. Supervisors: Prof. Nassir Navab (TUM CAMP), Prof. Nicholas Ayache (INRIA Sophia Antipolis), Dr. Dorin Comaniciu (Siemens Corporate Research, Princeton).

Record compiled 14 October 2026 from four independent sources and reconciled by DOI: OpenAlex (author A5067611389), Semantic Scholar (author 1707692), Crossref for venue, volume, pagination and author lists, and PubMed for the biomedical entries. Citation counts are as of that date and will drift.
Six records returned by the indexes are deliberately excluded: a book front-matter Contributors listing, a patent mis-filed as an article, one duplicate preprint, and three journal poster-session supplement compilations whose indexed record carries the whole session rather than an individual abstract.
