Deddy is a postdoctoral fellow at CSIRO Mineral Resources. His research interest is extractive metallurgy to produce and separate various metals or minerals from natural ores, wastes, and extraterrestrial planetary regolith, e.g. Mars. One of his current projects is valuable metals and minerals recovery from mine tailings.

Sanjay Singh is a Ph.D. research scholar in Geotechnical Engineering at the Indian Institute of Technology, Patna. His work focuses on sustainable mineral recovery, particularly the extraction of critical minerals from industrial wastes like red mud and fly ash and PCBs. With a background in Civil Engineering and a Master’s in Earthquake Science and Engineering from IIT (ISM) Dhanbad, he combines geotechnical modeling, GIS, and machine learning in his research. Sanjay has presented at several international conferences and authored book chapters on slope stability and environmental geotechnics. He recently received the Best Paper Presentation Award at the 3rd International Conference on Safe & Sustainable Mining Technologies. His goal is to advance environmentally responsible solutions for mineral extraction and slope stabilization.
