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.
