Services

Statistical Shape Modeling End-to-end SSM pipeline using ShapeWorks — from CT segmentation in 3D Slicer to landmark-free PCA-based shape variation analysis and visualization.
Geometric Morphometrics Landmark-based GM analysis in R (geomorph): Procrustes alignment, principal component analysis, group comparisons, and publication-ready figures.
Methods Review & Co-authorship Critical review of shape analysis methodology for manuscripts in preparation. Available as co-author when contributing substantially to analysis design and interpretation.
Research Collaboration Joint study design for musculoskeletal morphology research. Particularly suited for orthopedic implant R&D and clinical anatomy studies requiring surgical domain knowledge.

About

I practice orthopedic and hand surgery in Tokyo, Japan, while pursuing an active research program in computational anatomy. My work sits at the intersection of clinical practice and quantitative shape analysis — an intersection that remains rare in the global research community.

My current research focuses on three-dimensional morphological variation of the hand and wrist skeleton, using geometric morphometric and statistical shape modeling approaches to address questions that conventional measurement cannot resolve.

In Japan, I also provide medico-legal assessments of upper-limb injuries, including expert opinions and imaging review.

I welcome collaborations with researchers, clinicians, and industry partners who bring interesting anatomical questions and imaging data.

Consulting services are provided in an independent personal capacity and do not represent the views or activities of any affiliated institution.
