ExplainableAIforHumanLocomotion

Doctoral research on explainable, leakage-free machine learning for the biomechanics of human locomotion — segmented normality patterns and biomechanical pre-diagnosis.

I've been a researcher with the UNLOC (Unlimited Locomotion) group at Universidad San Jorge since 2024, and a PhD candidate in Health Sciences since 2025. My research develops explainable AI and leakage-free machine-learning pipelines for clinical gait and foot-pressure data — turning complex biomechanical signals into transparent, trustworthy support for pre-diagnosis.

Focus Areas

Research Domains

01

Explainable AI

Making ML models transparent for clinical and sports professionals. SHAP for feature contributions, LIME for local interpretability, Grad-CAM for visual attribution, and counterfactuals for actionable "what-if" reasoning.

02

Locomotion Biomechanics

Analyzing clinical gait and foot-pressure data — baropodometry, optical motion capture, OptoGait, and inertial sensors — to characterize segmented normality patterns and support biomechanical pre-diagnosis.

03

Leakage-Free ML

Reproducible, leakage-free machine-learning pipelines and per-pathology binary classification, so that reported performance reflects true generalization rather than optimistic data leakage.

04

Clinical Decision Support

AI that enhances rather than replaces clinical judgment — interfaces and explanations designed around clinician and sports-science workflows, validated against clinical standards.

Process

Research Methodology

01

Clinical Problem Definition

Frame locomotion pathologies where explainability is critical. Work with the UNLOC group and clinicians to define segmented normality and pre-diagnosis targets.

02

Data Acquisition

Clinical gait and foot-pressure data — baropodometry, optical motion capture, OptoGait, and inertial sensors — across diverse cohorts.

03

Leakage-Free ML Pipelines

Design machine-learning pipelines with rigorous, leakage-free validation so that reported performance reflects genuine generalization, not data leakage.

04

Explainable AI

Apply SHAP, LIME, Grad-CAM and counterfactual explanations to make model decisions transparent and clinically meaningful.

05

Per-Pathology Validation

Per-pathology binary classification and segmented normality patterns, assessed against clinical criteria for biomechanical pre-diagnosis.

06

Dissemination

Systematic review (PRISMA; PROSPERO) and methodological manuscripts sharing reproducible, explainable methods with the research community.

Insights

Key Findings

01

Explainability Increases Adoption

Clinicians and sports-science professionals are significantly more likely to act on AI recommendations when they understand the reasoning behind them.

02

Leakage Is the Silent Killer

Much of the reported accuracy in locomotion ML collapses under leakage-free validation. Honest pipelines matter more than headline metrics.

03

One Technique Isn't Enough

SHAP, LIME, Grad-CAM and counterfactuals reveal different facets of a decision. Combining them gives a fuller, more trustworthy explanation.

04

Normality Is Segmented

There is no single "normal" gait. Segmenting normality patterns is what makes biomechanical pre-diagnosis meaningful and fair.

From Lab to Field

Where Research
Meets Sport

My doctoral research on explainable AI and human locomotion has a natural applied home: sport. Through my innovation work with national and regional judo federations, the same methods — leakage-free pipelines, interpretable models, biomechanical pre-diagnosis — reach injury prevention, athlete monitoring, and the clinicians and coaches who support high performance.

The goal is the same in the lab and on the field: AI that the people behind human performance — sports scientists, physiotherapists, and the athletes themselves — can genuinely understand, question, and act on.
