About

Teaching machines to analyze medical images

I am a medical imaging AI researcher working on vision-language models for 3D radiology. My current research designs token-efficient architectures that let language models reason over CT volumes, alongside multi-scale models for tumor classification on MRI.

I am an MS student in Engineering Artificial Intelligence at Carnegie Mellon University, concentrating on AI in healthcare. I build research systems end to end, from data pipeline through model architecture to evaluation, and I care most about making diagnostic imaging AI work in low-resource and African clinical settings, which I pursue through the SPARK and CAMERA MRI Africa initiative.

My first degree was in Mechatronics Engineering at the Federal University of Technology, Minna. That background still shapes how I approach systems, though my work now sits firmly in research.

ICTC: Instruction-Conditioned Token Compression for 3D CT

Ongoing research

A dual-stage token-compression architecture for 3D chest-CT vision-language models. A frozen ViT slice encoder feeds a task-agnostic Perceiver-style intra-slice stage, then a FiLM-conditioned inter-slice stage produces instruction-aware visual tokens for a LoRA-adapted language model. This cuts the token cost of volumetric input for radiology report generation.

FPN-Mamba: Multi-Scale MRI Tumor Classification

Prepared for MICCAI 2026 workshop

A Feature Pyramid Network combined with a bidirectional Mamba block for pediatric medulloblastoma subtype classification on brain MRI, reaching AUC 99.35% and F1 94.54% on a 761-image dataset. Includes augmentation and class-reweighting pipelines built to address severe subtype imbalance.

White Blood Cells as False-Positive Sources in Malaria Detection

SPARK Academy capstone

Controlled YOLOv8 detection experiments test whether white blood cells systematically drive false-positive parasite detections in Giemsa-stained thick blood smears. DBSCAN spatial clustering and a Mann-Whitney U test quantify how much WBC supervision affects diagnostic reliability.

Research

Research Interests

My research asks how AI systems generalize across domains, especially in real-world noisy environments.

Medical Vision-Language Models

Architectures that let language models reason over volumetric medical images, with a focus on token efficiency and how visual representations should be conditioned on the clinical question being asked.

3D Medical Image Analysis

Multi-scale and state-space architectures for CT and MRI, particularly for tumor classification under small, imbalanced datasets where minority-class recall matters clinically.

Efficient & Trustworthy Clinical AI

Model compression and efficiency techniques have real costs in clinical accuracy, calibration, and robustness, and those costs may not fall evenly across patient groups.

AI for Low-Resource Healthcare

Diagnostic imaging AI has to work within the constraints of African and low-resource health systems, including affordable acquisition hardware and limited annotated data.
