Rather shyly, Ms Yu Lijie admits that these TV programmes inspired her to become a forensic scientist two years ago.
'It appeared as an exciting career and I have yet to be disappointed,' said Ms Yu, 24, who is now attached to the illicit drugs laboratory of the Health Sciences Authority (HSA).
There, she identifies and quantifies the amount of illicit substances seized by police and drug enforcement officers.
While the chemistry graduate from the National University of Singapore (NUS), was aware of what she was getting into, many of her colleagues who came into the profession a few years earlier, often had no inkling what they would be in for.
Ms Kee Koh Kheng, 28, who joined HSA in 2003, said: 'Then, forensic science was not so hot.
'Maybe because the crime scene investigation TV programmes or CSI shows had yet to capture the public's attention.'
'Only after I took up the job, did I find out that forensic science involves checking cloth fibres and bloodstain patterns .
As a member of the forensic chemistry and physics laboratory, the chemistry graduate from NUS also analyses cuts and tears in clothing and trace material found at crime scenes.
She has been to the United States thrice for training, the most recent for a two-month course in new developments in reading blood splatter patterns.
To cope with the disturbing sight of mangled corpses and blood-drenched crime scenes, she tries to stay 'emotionally detached.'
She said: 'I am a professional and cannot let my emotions get the better of me. My job is to get to the truth of what happened at a crime scene.
'Witnesses could be mistaken, memories could age but forensic evidence is for real because it has been verified by science.'
If forensic science was not 'hot' five years ago, it was practically unknown 19 years ago when Mr Michael Tay took it up.
On his return from France with a chemistry degree, he was posted to the Department of Scientific Services - the precursor to the HSA.
'I was an accidental forensic scientist as I had no idea what the job entailed and grew into it,' he said.
He grew to become the director of the forensic science division.
He said that the number of forensic scientists have more than doubled to 45 in the last 19 years and there are now more specialties.
These range from DNA profiling to identifying an individual from minute traces of blood, semen, hair or skin cells, to the use of computational fluid dynamics to simulate the spread of a fire through a building.
Another new specialty is bloodstain pattern analysis after a violent crime. Bloodstain patterns would reveal the type of weapon used in the attack, the minimum number of blows inflicted, the presence of a suspect at a scene, positioning and movements of the victim, perpetrator, and objects during events, and the sequence of events.
While the science might be the same, the TV shows stretch the truth by depicting forensic scientists carrying guns and interviewing suspects.
Said Mr Tay: 'Yes, we are called to examine major crime scenes but our work is mainly in the labs.'
This work is becoming more challenging as criminals are also learning from the CSI shows
Mr Tay said: 'In a murder case some years ago, a Filipino maid who killed a friend and dumped the body parts at Orchard MRT station and MacRitchie Reservoir Park, had washed the blood stains off the wall of her room and then put up new wallpaper.'
'But we found the evidence.'
