Brief Description


Dr. Kaka is presently working as an Assistant Professor in the Metallurgical and Materials Engineering department DIAT (DU), Pune. Before joining DIAT, he worked as an Assistant Professor in the Chemical Engineering department at Pandit Deendayal Energy University, Gujarat. He holds a B.Tech. Degree in first class with distinction, in Polymer Science and Chemical Technology from Delhi Technological University (Formerly Delhi College of Engineering). Further, he pursued an integrated Ph.D. from the Indian Institute of Science (IISc) Bangalore. His Ph.D. dissertation proposed a novel in-silico framework comprising a physics-based and data-science model for establishing the process-structure-property relationship in organic photovoltaics. His publication "Investigation of process-structure-property relationship in ternary organic photovoltaics" was featured on the cover of the Journal of Applied Physics as well as on the home page of AIP. Dr. Kaka was granted financial support by JNCASR from the DST-Synchrotron-Neutron project to conduct in-situ experiments at the SOLEIL synchrotron radiation facility, France, in 2020. Additionally, he has received travel grants from Tata-Trusts and Ras Al Khaimah Centre for Advanced Materials for attending international conferences.
