Dr. Rahul GoyalDr. Rahul Goyal is presently working as a Professor and Head of the Department of Mechanical Engineering at Manipal University Jaipur, India. He graduated in Mechanical Engineering from the University of Rajasthan and completed his master's from University College of Engineering, Kota in Thermal Engineering. He then pursued his Ph.D. degree from MNIT, Jaipur. His major research interests include alternative fuels in an IC engine, Waste heat recovery technology, Thermal energy storage, Combustion, Renewable Energy, etc. He has published more than 50 research publications in international peer-reviewed journals, reputed conferences, and book chapters. He also serves as a reviewer in various reputable journals. He has to his credit Invited Talks & Keynote addresses and chaired/co-chaired sessions at various conferences. He is a regular reviewer of research articles for many high-impact journals. He has supervised 3 PhDs and currently 3 research scholars are under his supervision. He is a life member of ISTE, India. Dr. Satyanarayan PatelDr. Patel is currently working as a full-time assistant professor in mechanical engineering at the Indian Institute of Technology (IIT) Indore, India. He supervises Ph.D., master, and undergraduate students; and implements a research project funded by Science and Engineering Research Board (SERB) India. Previously, he worked as a prestigious Alexander Von Humboldt Post-doctoral Fellow in the Nonmetallic-Inorganic Materials Research Group, Technische Universität Darmstadt, Germany. His research focuses on bulk lead-free ceramics (piezoelectric and ferroelectric) for energy storage, conversion, and caloric effects for solid-state refrigeration. He first demonstrated the elastocaloric and barocaloric effect in bulk ferroelectric ceramics using indirect measurements for solid-state refrigeration. He also explored an unforeseen component of the electric field-drivencaloric effect termed the inverse piezocaloric effect. Additionally, he performed work on the effect of compressive pre-stressed (mechanical confinement) for tuning ferroelectric/pyroelectric/-piezoelectric properties for energy storage/conversion and other device applications. The current research is focused on pyroelectric energy harvesting and the flexocaloric effect in ferroelectric materials. Dr. Abhishek SharmaDr. Abhishek Sharma has been working with BIT Sindri as an Assistant Professor in the Department of Mechanical Engineering. He has a total of 15 years of teaching and research experience in various reputed Indian universities. He is a graduate of Mechanical Engineering from Pt. Ravi Shankar Shukla University Raipur did his Master's in Thermal Engineering from Maulana Azad National Institute of Technology Bhopal and his doctoral degree in Mechanical Engineering from the National Institute of Technology Rourkela. In the last 10 years, he has been working in the field of waste to energy, alternative fuels for IC engines, renewable energy, air pollution, etc. He was a Principal investigator for a research project focused on the conversion of waste plastic into liquid fuel, sponsored by the Ministry of Human Resource Development, Government of India. He has to his credit around 80 research publications in international peer-reviewed journals, reputed conferences, and book chapters, which are readily available in Google Scholar and have more than 1387 citations with an h-index of 20. He has also been granted three Indian patents and registered two copyrights. Currently, 3 students are working under his guidance for their Ph.D. thesis. He has guided 10+ master's students in their dissertation works.
