In the hidden world of forensic chemistry, miniscule molecules can tell us stories and invisible traces can provide key information for achieving justice. From fingerprints to fibres and even lipsticks, forensic chemist Baljit Thatti will explain how chemistry provides voices to silent evidence through intricate preservation techniques.
Join Baljit for an exploration into real-world cases and the role of techniques including chromatography and spectroscopy, proving just how vital chemistry is in delivery justice. She will discuss how research is ever evolving to answer crucial questions to draw conclusions from a crime scene, including how even small traces of tyre marks at a scene could lead to valuable information of what vehicle was used in a hit and run.
