A Forensic Scientist is a scientific investigator who helps to solve criminal cases. They use scientific techniques, such as examining and analyzing evidence in a laboratory, in order to assign criminal responsibility and solve moral and ethical dilemmas. They analyze blood, fiber, and other types of evidence, such as fingerprints, and they also use DNA to identify criminal offenders. Forensic scientists are responsible for providing key evidence in criminal trials that can help to identify the guilty party. Many people enjoy being a Forensic Scientist because it is a highly challenging and rewarding career. Forensic Scientists often get to work on unique and interesting cases that are not available to other scientific fields. Additionally, the work allows them to make a significant contribution to society by helping to ensure justice is served. Finally, many Forensic Scientists appreciate the intellectual stimulation that comes with their work. The work also provides a sense of certainty in a field fraught with uncertainty because Forensic Scientists can rely on the facts and evidence to determine their conclusions.
