A clinician diagnosing diabetic macular oedema consults fundus photographs, OCT B-scans, fluorescein angiography, and the patient&rsquo;s longitudinal record simultaneously. My research develops deep learning architectures that can fuse these heterogeneous modalities into a coherent representation.</p> <h2 id="key-research-directions">Key research directions</h2> <h3 id="cross-modal-feature-alignment">Cross-modal feature alignment</h3> <p>Standard concatenation of modality-specific features often fails because different modalities live in incompatible representation spaces. I explore contrastive objectives and cross-attention mechanisms that align representations across modalities without requiring paired data at every follow-up visit.</p>
