ResearchOverall I work on multi-modal foundation models for visual understanding. I'm currently building models that can understand and reason about temporal events through visual, textual and temporal information. I have experience in creating large-scale multi-modal systems and working with unstructured data. I'm particularly interested in the interdisciplinary applications of these techniques, collaborating with researchers in archaeology, grape pathology, and other domains to address real-world challenges. |

Scale-Aware Recognition in Satellite Images under Resource Constraints
Shreelekha Revankar, Cheng Perng Phoo, Utkarsh Mall, Bharath Hariharan, Kavita Bala ICLR, 2025 paper / code / project page We introduce a new approach to scale-aware recognition in satellite imagery under resource constraints. Our approach allows one to accurately detect various concepts using a fixed budget of HR imagery, outperforming entirely HR baselines by more than 26% mAP in zero-shot techniques, and more than 8% mAP in supervised techniques using 5× fewer HR images. |
