Pradeep’s work is in the area of molecular materials and surfaces. In his formative years, he measured the very
first vibrationally resolved
photoelectron spectrum of Ar2 and discovered a novel transition metal ion, NiH2+. These days most of his work is on nano particles and ....
Our research group consists of PhD students, post-doctoral associates, undergraduate students, visiting students and project staff. Several students have graduated from the group and are located in various parts of the world. All of them have contributed to evolution of the laboratory.
