Sharmili is currently a research fellow in ROSE lab at NTU. Her research focuses on computer vision and machine learning technologies for various kinds of detection and recognition tasks. Prior to this she was with the image analysis team of A*STAR-NUS Clinical Imaging Research Centre headed by Dr. David Townsend where her research was geared towards personalized radiotherapy for cancers of the pelvis such as cervical, prostrate and colorectal carcinoma using Positron Emission Tomography/ Magnetic Resonance (PET/MR) imaging. She finished her PhD under Dr. Michael S. Brown at the School of Computing of National University of Singapore. During her PhD she developed advanced tools for radiological reporting and biomedical image analysis using routine clinical data.

Her main research interests lie in the fields of computer vision, machine learning, pattern recognition and biomedical image analysis.
