Biography

Dr. Deepika Malhotra joined Pacific Northwest National Laboratory (PNNL) in 2014 and currently is a Scientist in Advanced Energy Systems group in the Energy Processes and Materials Division at PNNL. Her research at PNNL is focused towards designing, synthesis and scale-up of modular solvent for CO2 capture and acid gas separations. She has extensive experience in design of new synthesis, process chemistry, scale-up, developing efficient, robust, and scalable processes for the small organic compounds and materials from grams to kilograms scale. Before joining PNNL, Dr. Malhotra worked at GlaxoSmithKline (UK), where she worked in the Immuno-Inflammation Center for Excellence in Drug Discovery (II-CEDD) developing Structure Activity Relationship (SAR) for pharmaceutical drug discovery.
