Dr. Ratan

Scientist-F

शोध में रूचि

Specialisation in Palynology:Has worked on a wide range of problems of varying ages and areas which involve the use of palynofossils for their resolution, such as Gondwana sediments (Permiam-Triassic), Deccan Intertrappean beds (Late Cretaceous-Early Palaeocene) and Quaternary fluvio-glacial & lacustrine deposits of the Higher Himalayas and the Polar Region.
