Prior to his appointment at PNNL, Dr. Thallapally was a postdoctoral research fellow at University of Missouri-Columbia working with Prof. Jerry L. Atwood. During his stay at Columbia, he developed porous organic and metal organic frameworks for Gas (Hydrogen, Methane and Acetylene) storage and separation (CO2) applications. He is major contributor for DOE - EERE collaborative project with PNNL on crystalline solids for Hydrogen storage applications and played a major role in The Alliance for Collaborative Research in Alternative Fuel Technology (ALL-CRAFT) program on materials for Methane Storage Applications. His work has been highlighted in several external press including Science Editorial Choice [Science 2005], Chemical Engineering News, several highly accessed and hot articles in Angew Chem Int. Ed., and Chemical Communications. Dr. Thallapally currently is a scientist working on the development of Hierarchical porous materials for Energy and Environmental applications including gas storage, separation heating and cooling and so on.
