Research Scholar at IITB & Monash University | Project JRF at MIU, ISI Kolkata | MTech in Computing & Mathematics, IIT PKD | 3D Reconstruction from Projection Images (Cryo-EM) | Machine Learning
I am a Joint PhD Scholar at IIT Bombay (C-MInDS) and Monash University (ECSE), with specialization in 3D image reconstruction from projection images (Cryo-EM) and Artificial Intelligence for healthcare applications. With a strong foundation in Computing and Mathematics (MTech, IIT Palakkad) and Pure Mathematics (Visva Bharati University), my research bridges advanced image processing, biomedical signal processing, and AI/ML. Previously, I served as a Project JRF at the Machine Intelligence Unit, ISI Kolkata, where I worked on AI-driven frameworks for affordable diabetic retinopathy detection and prediction. My earlier work also includes Photoplethysmography (PPG) signal quality assessment using graph-based features and Graph Neural Networks. I enjoy working at the intersection of mathematics, AI, and healthcare to create solutions that are both scientifically rigorous and practically relevant.

Biomedical Signal Quality Assessment Using Machine Learning Classifiers On Graph Features and Graph Neural Networks.
August 1, 2023 – May 1, 2024
In Phase 1 (Aug 23 – Dec 23) of this project, we proposed a variant of the Horizontal Visibility Graph algorithm and utilized its graph features for the classification of noisy and clean PPG signals using ML classifiers. The proposed Horizontal Visibility Graph algorithm outperformed the old one significantly in terms of accuracy. Phase 2 (Jan 24 – May 24) of this project was focused on deep learning, specifically utilizing Graph Neural Networks for the classification of PPG and EEG signals.

Cultural Fit Analysis
The candidate's background is heavily academic and research-oriented, which aligns well with roles requiring deep theoretical understanding and innovation. The diversity of projects, from medical applications to graph neural networks, shows a broad interest within ML. The pursuit of multiple PhDs indicates a strong drive for continuous learning and intellectual curiosity, which can be a good cultural fit for research-intensive organizations. However, the lack of industry experience might require adaptation to a more product-focused environment.
Soft Skills & Operational Fit
The candidate's academic and research background suggests strong analytical and problem-solving skills. The teaching assistant role implies good communication and mentoring abilities. However, there is limited direct evidence of operational fit in a fast-paced industry setting or specific team collaboration scenarios outside of academic projects.
