Lalji Singh — Indian geneticist and pioneer of DNA fingerprinting

Research and contributions

Singh made contributions across several areas of molecular biology, including the molecular basis of sex determination, methods for wildlife conservation forensics, and genetic studies that informed the understanding of human evolution and migration. His work adapted international DNA-profiling methods to India's diverse population, helping establish protocols for paternity testing, criminal identification and species identification in wildlife crime.

Institutions and leadership

Over his career Singh led major research organizations and helped build laboratory capacity for genetics research. He played a prominent role in translating laboratory science into applied services used by police, courts and conservation agencies. His public service and scientific leadership were recognized nationally; he received the Padma Shri in 2004 for contributions to science and technology policy and practice.

Practical applications and examples

• Forensic casework: DNA evidence for identity and paternity testing.
• Wildlife protection: genetic identification of ivory, horn and meat to combat poaching.
• Population studies: use of mitochondrial and Y-chromosome markers to trace ancestry and migration patterns.

Background and legacy

Born in Kalwari, Jaunpur in Uttar Pradesh (UP), Singh combined laboratory research with institutional building and outreach. He died of a heart attack on 10 December 2017 in Varanasi, Uttar Pradesh. His legacy endures in the widespread use of molecular tools in Indian forensics, wildlife conservation and human genetics research.
