C. Salient Research Achievements:  Dr.  Haldar has presented a Research Paper in the 18th WB State Science & Technology Congress, dated 28th Feb. to 1st March,2011, venue at Ramakrishna Mission Ashrama, Narendrapur, Kolkata-103 which has been nominated as a best oral presentation in the Congress. He has also been invited to attend the ACISNR, SUNY at Fredonia, Fredonia, USA, May 5-7, 2010. However, due to unanticipated delay in obtaining the US visa, he could not participate in the ACISNR-2010.

D. Dr. Prabir Kumar Haldar’s research priority includes High Energy Physics (Experimental).  Studied  Relativistic  Heavy ion collisions energy range from few GeV to few hundred GeV.
