J Radhakrishnan IAS Age, Early Life and Education
Childhood
Radhakrishnan was born in Madras on 16 September 1966. As of October 2026, he is 60 years old.
His father served in the Indian Air Force as a Warrant Officer. Air Force postings kept the family on the move across the country. This meant the young Radhakrishnan grew up in several cities rather than one hometown.
Schooling
He studied in Kendriya Vidyalayas in Kanpur, Chandigarh, Nashik and Deolali. Kendriya Vidyalayas are central government schools built for children of transferable employees. Changing schools often is hard for a child. It also teaches quick adjustment to new places and people, a skill that suits a civil servant well.
Graduation and College
After school, he chose veterinary science. He earned his Bachelor of Veterinary Science (BVSc) degree in 1988 from the Veterinary College in Bengaluru, and he passed in First Class.
For his postgraduate studies, he moved to Kerala Agricultural University. There he specialised in Animal Breeding and Genetics. The official DoPT civil list records his qualification as M.V.Sc. (Animal Breeding).
Academic Achievements and Civil Services Journey
After his studies, he began preparing for the UPSC Civil Services Examination. He cleared it in his third attempt and joined the IAS in 1992.

Career and Success Story
First Posts
After his training, Radhakrishnan took charge as Sub-Collector of Thoothukudi (then Tuticorin) on 9 August 1994. A Sub-Collector is a young officer’s first big field job. He looks after a revenue division and learns how government works on the ground.
He then moved to Chennai-based roles. He worked as Deputy Secretary in the Finance Department and later in the Health and Family Welfare Department. In March 2000, he became Commissioner of Land Revenue and District Administration for Chennai district.
Collector of Salem
In July 2001, he became Collector of Salem. He held the post until July 2003. During this time, he worked against female infanticide.
The Tsunami Years
His name reached national and global news in December 2004. He was the Collector of Thanjavur when the Indian Ocean tsunami struck the Tamil Nadu coast on 26 December. He organised relief work there and earned wide praise.
In January 2005, the government moved him to Nagapattinam, a district that had suffered even more damage. He served there until May 2006. He oversaw relief camps and the long task of rebuilding lives. Reports describe him as a “people’s collector” for his hands-on style.
The relief work brought him invitations from abroad. The United States Department of Education invited him to speak on tsunami issues in Washington D.C., Seattle, San Francisco and Hawaii. The Government of Sri Lanka also invited him to share his experience with its relief workers.
Work with the United Nations
From March 2009 to March 2012, he headed the Disaster Management team of the United Nations Development Programme (UNDP) in India. This role used the lessons he learned on the Tamil Nadu coast.
Health Department and Covid-19
Radhakrishnan led the Health and Family Welfare Department in more than one stint. He is best remembered for the Covid-19 period. In June 2020, he took charge as Health Secretary, and he held the post until December 2022.
Reports credit his earlier tenure in the department with progress in maternal mortality and organ donation. They also credit him with preventing disease outbreaks after the Chennai floods and with controlling dengue cases.
Chennai and the Power Sector
In May 2023, he became Commissioner of Greater Chennai Corporation, the civic body of the state capital. He served there until July 2024.
After a short stint in the Co-operation, Food and Consumer Protection Department, he took charge in February 2025 as Chairman and Managing Director of the Tamil Nadu Electricity Board and its linked companies. These included TNPDCL, TNGECL, TANTRANSCO and TNPGCL.

Dr J Radhakrishnan IAS Current Posting and Retirement Date
On 15 July 2026, the Tamil Nadu government carried out a large reshuffle of senior IAS officers. Radhakrishnan was moved from the power sector and appointed Director of the Anna Administrative Staff College. He was also named Director General of Training, replacing C Samayamoorthy, who held the additional charge. V Arun Roy took over his earlier power sector responsibilities.
The Secretariat lists his current post as Director General of the Anna Institute of Management and Training, with effect from 16 July 2026. This is the same training institution for civil servants in Tamil Nadu.
Retirement is a question many readers ask. He was born on 16 September 1966, so he turned 60 in September 2026. Under the standard rule for All India Services, an officer retires on the last day of the month in which he turns 60. For Dr Radhakrishnan, that points to 30 September 2026. The DoPT-based StockLens profile also lists his expected retirement in 2026.

On 2 February 2025, the couple solemnised Meena’s wedding to Manimaran at the Sri Nellukkadai Mariamman Temple in Nagapattinam. Meena works as a nurse. Radhakrishnan has said that he could not hold back his tears when Meena first called him “appa” during a visit in 2018.
