Here’s the short interview of Quiz maker:

On behalf of Sherlock Institute of Forensic Science I had a short interview with Dr. Vijay Arora Sir and here is what he says to all the student community and life time learners. 

1. Forensic Traumatology is a Branch of Forensic Medicine in India. How would you like to explain the scope of this subject in our country?

In India, Forensic Traumatology is mainly taught as a part of Forensic Medicine under the headings of mechanical injuries, injuries and its medico legal aspects, regional injuries etc. and not as a separate subject. As the knowledge of injuries and its medico legal aspects is very important for writing post mortem reports, injury reports (MLRs) etc. hence every doctor, police person , lawyer  and even judicial officer should study this subject.

2. Would you like to share your experiences in making this quiz ?

It was really a very nice experience and I would like to thank SIFS for giving me this opportunity.

3. I do understand from this short conversation that this subject is an emerging branch. So talking about the global perspective where do you see this subject in the next few years? 

Keeping in view the importance of this topic/subject especially in the process of police investigation and judicial decisions, I think this subject will definitely flourish in the next few years.

4. I really appreciate your time sir for giving us such insights into the subject and also for preparing such an engaging Quiz. What would be your message for the aspiring Forensic Traumatology students?

Study with honesty, dedication and take interest in the subject and only then you will realise that Forensic is unique.
