Naha was also Visiting Professor, University of California at Berkeley (1968) and Senior Lecturer, La Trobe University of Victoria (1975-76).

Academic and Research Achievements:Naha’s contributions relate to: (i) time of formation and kinematic significance of deformation lamellae in quartz; (ii) geometry of reclined folds; (iii) large-scale architecture of migmatites; (iv) metamorphism in relation to stratigraphy, structure and movements in eastern Singhbhum and the Simla Himalayas; (v) revision of stratigraphy and structure in the Early Precambrian terrance of central Rajasthan and southern India; (vi) methods of recognizing angular run conformity in metamorphic terraces, with groups of rocks on either side of the unconformity involved in superposed folding; and (vii) methods of recognizing coaxial refolding prior to non- coaxial deformation.

Others Contributions:Naha was the Chairman, Indian National Committee on Continental Lithosphere and Member, editorial boards of: Indian Journal of Earth Science, Indian Journal of Geology and Precambrian Research. He was Member, INSA Council (1990-92)

Awards and Honours:Naha was the recipient of SL Biswas Medal (Asiatic Society) (1958); National Mineral Award (1970); Shanti Swarup Bhatnagar Prize (1972); UGC National Lecturer (1978-79); Jawaharlal Nehru Fellow (1986-87); Professor KP Rode Memorial Lecture (Indian Science Congress) (1992); Professor HC Dasgupta Memorial Lecture (Geological, Mining & Metallurgical Society of India) (1992); Dr S Balakrishna Memorial Lecture (Andhra Pradesh Academy of Sciences) (1992). He was a Fellow, Indian Academy of Sciences, Bangalore; Life Fellow, Geological, Mining and Metallurgical Society of India (also Council Member), Geological Society of India (also Council Member).

The Indian National Science Academy has instituted the ‘Professor K Naha Memorial Medal’ in his honour.
