Devendra Lal

Primary thrust of D. Lal's work is in the fields of cosmic ray physics, nuclear physics, earth sciences and solar system physics. His early work was in fields of composition and energy spectrum of primary cosmic radiation, and elementary particle physics. He currently explores different ways in which natural processes can be utilized with an advantage to understand planetary physical and chemical processes and their rate constants. His work has emphasized studies of cosmic ray produced radioisotopes in diverse terrestrial environments, atmosphere, lakes, oceans, and sediments; and of nuclear tracks and radioactivtiy in moon, meteorites and terrestrial samples. He developed several nuclear methods in close collaboration with his students.
