Summary
👤
Senior🎓
Top SchoolKohulan Rajan is a project lead for AI and automation who turns cutting-edge computer vision and NLP research into production systems for cheminformatics, most notably as lead developer of DECIMER.ai — the first comprehensive open-source platform for automated chemical structure recognition published in Nature Communications and featured by Google Cloud. With 8+ years of experience and a PhD bridging chemistry and AI, he combines deep research (21+ papers, 1,600+ citations) with production engineering in TensorFlow/PyTorch, FastAPI, Docker/Kubernetes and GCP to scale ML from prototypes to global platforms. He co-developed the COCONUT natural products database, accelerating open drug-discovery workflows, and has been recognized as a Google TPU Research Cloud Fellow and CVPR demo presenter. Beyond code and papers, he mentors students, teaches AI/ML, champions open science, and brings a creative edge as a professional photographer and published Tamil poet — a background that informs his pragmatic yet inventive approach to problem solving.
