Bioinformatics & Physics-Informed Machine Learning
Physics-grounded modelling, learning and validation for Bioinformatics
Bioinformatics develops computational methods for genomic, transcriptomic, proteomic, metabolomic, structural and systems-biology data. It supports sequence analysis, molecular modelling, pathway inference, single-cell analysis, evolution and precision medicine.
In this branch, “physics-informed” may include molecular mechanics and stochastic dynamics, but broader mechanistic priors—reaction networks, mass action, phylogeny, thermodynamics and biological topology—are often more appropriate. The prior must be explicit and scientifically defensible.
This page presents ten focused research areas, degree-level project pathways, selected publications and direct support through the PIMLS biweekly members meeting.
This Bioinformatics guide covers Physics-Informed Neural Networks (PINNs), physics-guided machine learning, scientific machine learning, neural operators, hybrid models and engineering digital twins. Explore the research and project pathways below, then join the Physics-Informed Machine Learning Society to connect with the international PIMLS community.

Why this combination matters
Why Bioinformatics Needs Physics-Informed Learning
Use available scientific knowledge to make limited data more useful, transparent and testable.
Incomplete engineering models
Learn uncertain parameters, closures or discrepancies around an inspectable mechanistic foundation.
Transfer across conditions
Test whether structured models generalize across geometries, materials, assets, operating regimes or sites.
Trustworthy evidence
Use physical residuals, independent measurements, uncertainty and conventional engineering baselines before deployment.
Ten focused directions
Major Bioinformatics PIML Research Areas
Each card connects a meaningful Bioinformatics question with suitable scientific knowledge, modelling choices and evidence needed to test it.
01
Single-Cell Dynamics
Destructive assays provide snapshots rather than trajectories. PIML opportunities: Use neural SDE/ODE and population constraints to infer continuous dynamics.
Model and evidenceGoverning equations, calibrated measurements and held-out operating conditions
02
Gene-Regulatory Networks
Many network structures fit observational expression. PIML opportunities: Combine topology, kinetics and perturbation data with identifiability analysis.
Model and evidenceMechanistic and data-only baselines, uncertainty and independent validation
03
Metabolic Flux Inference
Fluxes must satisfy stoichiometry and capacity constraints. PIML opportunities: Fuse constraint-based metabolic models with expression and isotope data.
Model and evidenceGeometry, material or system parameters, sensor data and physical residuals
04
Protein Structure and Dynamics
Geometry and interactions obey symmetry and energetics. PIML opportunities: Use equivariant networks and molecular-energy priors with independent structural tests.
Model and evidenceGoverning equations, calibrated measurements and held-out operating conditions
05
Molecular Property Prediction
Small chemical datasets invite shortcut learning. PIML opportunities: Use symmetry, units, charge and thermodynamic features with scaffold splits.
Model and evidenceMechanistic and data-only baselines, uncertainty and independent validation
06
Drug–Target Interaction
Binding depends on geometry, energetics and assay context. PIML opportunities: Combine structural physics with calibrated learning and prospective validation.
Model and evidenceGeometry, material or system parameters, sensor data and physical residuals
07
Spatial Omics
Expression is coupled to tissue geometry and diffusion/signalling. PIML opportunities: Use graph and transport priors to infer spatial processes.
Model and evidenceGoverning equations, calibrated measurements and held-out operating conditions
08
Cell Signalling
Reaction networks contain uncertain rates and hidden states. PIML opportunities: Learn residual kinetics around mechanistic pathway models.
Model and evidenceMechanistic and data-only baselines, uncertainty and independent validation
09
Phylogenetics and Evolution
Sequences are related through evolutionary trees and substitution processes. PIML opportunities: Embed phylogenetic structure and test transfer across clades.
Model and evidenceGeometry, material or system parameters, sensor data and physical residuals
10
Multi-Omics Integration
Different assays observe linked biological states with different noise. PIML opportunities: Use shared mechanistic latent states and modality-specific measurement models.

Frequently Asked Research Questions
These answers help students avoid common scope, terminology and validation mistakes.
Still have a question?
Use the biweekly meeting form for research guidance.
Request accessNo. Bioinformatics projects may use physics-guided features, hybrid residual models, differentiable simulators, neural operators, constrained architectures or data assimilation. State exactly what knowledge is incorporated.
Choose one engineering question, a measurable output and a defensible mechanistic baseline. Add learning only where data can identify an uncertainty or discrepancy.
A meaningful question, justified prior knowledge, deployment-level holdouts, strong baselines, ablation, uncertainty, reproducibility and honest limitations.
Simulation can broaden coverage, but simulation-only evidence cannot establish real-system accuracy. Use calibrated experiments, field measurements or trusted independent references appropriate to the claim.
