  Dr. Raj Kumar, Research Associate (RA) of Institute of Forensic Science & Criminology, Panjab University, Chandigarh, Indi ais going to attend an International conference which will be held at Auckland, New Zealand.He is Research Associate under the supervision of Dr. Vishal Sharma, faculty in the Institute.

Dr Vishal Sharma’s group is actively engaged in the research on Forensic applications. He said “Forensic science is continually evolving with new techniques/methods and hence helping the judicial system in legal cases where the forensic examination is necessary”. In this direction we are also evolving non-destructive, robust and smart methods to tackle high-tech smart criminals and thus enabling for effective criminal justice system.”

Raj Kumar has been invited to present his research work in 10th International Conference on Advanced Vibrational Spectroscopy, at Auckland, New Zealandw.e.f. 6th July to 14th July 2019. He is going to present the recent research of the group on“ATR-FTIR and multivariate analysis for the characterization and discrimination of writing paper types: A Forensic Application”.For presenting this work he has been selected for an International travel support award from Department of Science and Technology (DST), Govt. of India. DST is sponsoring this conference trip including return airfare, a full conference registration and visa application fee.

 In many legal cases, the paper becomes very important evidence to ascertain the connection between forged and genuine document. It is very important in some cases to determine whether two paper sheets are identical or have a common origin or not. In the current study, we have used non–destructive approach i.e. Fourier Transform Infrared spectroscopy (FTIR) combined with multivariate chemometric analysis to differentiate various types of writing/photocopying paper samples. This study will be highly useful in forensic document examination work in legal cases, where the authenticity of the document is challenged.

The results are completely analytical and, therefore, overcome the problem encountered in traditional routine light/radiation scanning methods which are still in practice by various questioned document laboratories. He further said “this technique are very simple, robust, require no sample preparations and hence saves time too.” These methods could also be extended to cultural heritage items, where such dispute cases where the heritage documents could be interchanged for the beneficiary purpose. In the future, it can be quite possible to create an FTIR database of more paper samples for the identification of unknown/suspected paper samples.
