About Me

I am Senior Imaging Scientist and lead Applied Imaging & Analytics team at Corteva Agriscience. My Ph.D. research involved designing image processing techniques and computational models that can facilitate automated cervical cancer diagnosis from histopathologic images of tissue biopsies. I have worked with various biomedical image databases like cervical histology (microscopy images), cervical cytology (microscopy images), chest X-ray scans, GI tract polyps from colonoscopy and wireless capsule endoscopy, foot prosthesis; and natural images datasets like human face images and scene text images.
