TMO-Net
An explainable pretrained multi-omics model for transferable oncology prediction and pathway-level interpretation.
- Transferable multi-task learning
- Pathway-level interpretation
- Precision oncology workflows
Research at FengGao Lab
AI for the full continuum of colorectal cancer care
We use colorectal cancer as a flagship clinical setting to build explainable, multimodal, and workflow-aware AI. The program connects disease biology, medical imaging, treatment response, and clinical reasoning while keeping every claim tied to the evidence that supports it.
Research map
A disease-first research program
Rather than treating models as isolated outputs, we organize the lab's work around connected capabilities that move from disease biology to clinically grounded prediction and intervention.
Program 01
Explainable Omics & Disease Mechanisms
We use biological knowledge and interpretable learning to identify reproducible disease states, molecular subtypes, and mechanisms that can support patient-level stratification.
Selected studies
- Senescence-based CRC subtyping MedComm / 2023
- TLS heterogeneity and TLSscore International Journal of Surgery / 2024
- MotifCC immune classification Cancer Letters / 2026
DeepCC
A pathway-informed deep learning framework for robust cancer molecular subtype classification.
- Pathway-informed ANN
- Single-sample prediction
- Robust to missing data
Program 02
Multimodal Foundation Models
We learn transferable representations across radiology, pathology, and molecular data so that clinically useful signals remain available when labels or modalities are limited.
Selected studies
- CRCME: pathology-guided CT representation learning Ongoing manuscript / public record pending
CRCFound
A self-supervised CT foundation model for diagnosis, staging, molecular prediction, and prognosis in colorectal cancer.
- 5137 unlabeled CT scans

Brim
An interpretable bridged multimodal fusion model that links histology and molecular data for pan-cancer prognosis.
- 12 cancer types
- Robust to missing modalities
- Histology-to-genomics bridging
Program 03
Clinical Prediction & Longitudinal Imaging
We design patient-level systems that remain stable across cohorts and platforms, with particular emphasis on treatment response, recurrence, and deployable single-sample prediction.

Program 04
Data-efficient Medical Vision & Computational Surgery
We build efficient visual models for volumetric imaging and operative scenes, reducing annotation burden while preserving anatomical and temporal context.
Selected studies
- FSA-Net for laparoscopic anatomy MICCAI / 2025
- CRC-2000 dataset and benchmark IEEE TMI / 2026
SegMamba-V2
A general 3D medical image segmentation backbone for long-range volumetric modeling across organs and modalities.
- CRC-2000 benchmark
- Tri-orientated spatial Mamba
- 4 large-scale datasets
SOUSA
A unified weakly and semi-supervised segmentation framework that learns from sparse labels and unlabeled medical images.

Clinical data engine
One disease-focused platform across the full care continuum
More than 50,000 structured CRC records connect routine CT and MR, digitized pathology, selected endoscopy and ultrasound, molecular profiling, treatment, and follow-up. ICGC-ARGO provides the molecular reference layer for a platform that keeps growing through routine clinical care.
- 10,000+
- CRC surgeries expected in 2026
- 10,000+
- patients with digitized pathology
- ~12,000
- pathology slides digitized each month
Emerging program
Medical cognitive agents for coordinated clinical reasoning
We are extending validated multimodal capabilities into a modular architecture that can coordinate evidence retrieval, perception, boundary checks, and workflow execution. This is an active research and prototyping program, not a deployed autonomous clinical system.
Decision orchestration
Break down clinical questions and coordinate specialist modules.
Multimodal perception
Connect structured records with imaging, pathology, and omics.
Evidence and safety
Retrieve guidance, grade evidence, and surface uncertainty.
Workflow execution
Support clinicians, researchers, and longitudinal follow-up.
Beyond CRC & open science
Evidence of generalization
Colorectal cancer is our flagship clinical setting, while the underlying methods are tested across cancers, modalities, and real clinical workflows.
