N. Ramachandran had a distinguished career in the Indian Police Service (IPS Assam Meghalaya 1978), serving in several sensitive districts of Assam, like Goalpara, Kamrup, Tezpur-Darrang, Guwahati City and Nagaon. As Special Branch Chief, he spearheaded major revamp of the State’s intelligence and special operations network. His contributions towards bringing an end to militancy and terrorism in the State are well-recognised.  Deeply involved in counter-terrorism efforts against various insurgent groups in Northeast India, he retired as Director General of Police, Meghalaya.

At the Central Government level, he served in the elite Special Protection Group (SPG), responsible for the security of the Indian Prime Minister. Over two separate stints spanning 13 years, he contributed significantly towards shaping the SPG into a world-class security organization, known for its ‘zero error’ culture and the continuous pursuit of professional excellence.

Ramachandran served as the Chairman and CEO of Cochin Port—one of India’s 12 Major Ports—from 2005 to 2011. He is credited with extensive labour reforms during this period and spearheading major infrastructure and modernization projects, leading to significant capacity expansion. By implementing a comprehensive SAP-based ERP system, he provided leadership for a digital overhaul, streamlining processes and driving a complete operational and cultural transformation.

During this period, the Government of India appointed him as Chairman of the High-Level Committee on the security of India’s Major Ports and commercial maritime operations. In this capacity, he made extensive contributions to strengthening the security framework of all Major Ports and shipbuilding facilities across the country. He also chaired various committees on the standardization of security equipment and protocols at India’s ports. He has done extensive work on national security, particularly in the areas of insurgency, terrorism, illegal immigration, and the transnational smuggling of weapons and drugs.

Ramachandran believes that public officials must uphold constitutional principles, maintain integrity, provide sound advice, and happily resist political pressures, even at the risk of falling out of favour. At the same time, being passionate and taking risks are necessary for mission success. Ardently committed to the rule of law, police professionalism and operational independence, he founded the Indian Police Foundation (IPF) post-retirement, advocating for police reforms and ethical policing. As IPF’s President, he actively engages with police organisations, universities and training institutions, contributing to research and ideation in national security, maritime security, field policing, police modernization, and governance reforms.
