🏢 Professional Experience:

Dr. Sandeep Mahajan has built a distinguished career in materials science and physics through various research and academic roles. His journey began during his M.Sc. studies at Devi Ahilya University in Indore, where he investigated the structural properties of pure and strontium-doped lanthanum orthoferrite using X-ray diffraction. This early research laid the foundation for his subsequent academic pursuits.

As a Ph.D. scholar at the Department of Physics and Astrophysics, University of Delhi, Dr. Mahajan delved deeper into the field of ferroelectric ceramics. His doctoral work focused on synthesizing and characterizing barium titanate-based ceramics, exploring novel compositions and innovative processing techniques such as microwave sintering and mechanochemical alloying. These efforts were aimed at enhancing the materials’ piezoelectric and dielectric properties, crucial for their application in electronic devices.

Following his doctoral studies, Dr. Mahajan embarked on a series of impactful research positions. At the Solid State Physics Laboratory (SSPL), part of India’s Defense Research and Development Organization (DRDO), he served as a Research Fellow from 2004 to 2009. Here, he contributed significantly to the development of microwave dielectrics, piezoelectric materials, and thin films for MEMS devices. His expertise in microwave sintering and characterization techniques, such as SEM and XRD, enabled him to optimize material properties for specific applications in advanced electronic systems.

During his tenure as a Research Associate at the Indian Institute of Technology Delhi (IITD) from 2009 to 2010, Dr. Mahajan focused on multiferroic systems. His responsibilities included operating and maintaining SQUID magnetometer systems for characterizing magnetic materials and exploring non-lead-based multiferroic compounds. This role further honed his skills in experimental physics and solid-state chemistry, contributing valuable insights to the field of functional materials research.

Earlier in his academic journey, Dr. Mahajan pursued both his M. Phill and M. Sc. degrees under the UGC-Consortium for Scientific Research (UDCSR) at Indore. His projects involved advanced techniques such as Energy Dispersive X-ray Reflectivity Measurement and the study of phase transformations in complex oxide materials. These experiences not only broadened his experimental repertoire but also underscored his commitment to cutting-edge research in materials science.

Throughout his career, Dr. Sandeep Mahajan has demonstrated a steadfast dedication to advancing the frontiers of materials science, particularly in the synthesis, processing, and characterization of functional ceramics and thin films. His contributions continue to shape the field, paving the way for innovative applications in electronics, telecommunications, and beyond.
