Director's Message
Smt.Sharada Avadhanam M.Sc,M.A,
As all of you, I am also Interested in Forensic Science right from my childhood. The word "Forensic" is derived from a latin word "Forensis" which means belonging to courts of justice. Forensic Science broadly means application of scientific principles and techniques in the administration of justice.

The Judiciary enough evidence to convict the suspect.
