He has been honoured with several prestigious fellowships and awards in recognition of his outstanding academic achievements and published works. These include the CSIR Research Fellowship at IIT Delhi, the BK Plus Fellowship, and the Yonsei Postdoctoral Fellowship. Dr. Pathak actively engages in research collaborations both nationally and internationally, fostering cross-disciplinary dialogue and driving developments in spintronics. He has published approximately 34 research articles in reputed SCI-indexed journals and holds 2 patents. His unwavering dedication to scientific investigation, combined with his commitment to education and mentoring, has established him as a rising researcher and a prominent member of the scientific community.
Work Experience
Dr. Pathak pursued his Ph.D. in Physics with a focus on nanomagnetic materials at the Indian Institute of Technology Delhi (IIT Delhi), New Delhi, India. Following the completion of his doctorate, he spent three years as a Researcher at Yonsei University (QS world ranking 73), where he contributed to the advancement of magnetic memory technology, a crucial area for data storage and information processing. He later served as a Research Professor at Korea University (QS world ranking 74), Seoul, South Korea, for three years. In 2020, Dr. Pathak joined the esteemed faculty at the Department of Physics, UPES Dehradun in India. Since then, he has been actively involved in teaching and mentoring students, guiding them in their pursuit of knowledge and excellence in materials science.
Research Interests
The primary focus of Dr. Pathak's research has been on the investigation and development of nano-sized ultra-thin magnetic and spin systems. These nano-sized ultra-thin magnetic and spin systems include magnetic superlattices, MTJs, and ferromagnetic nanomaterials. In 2017, he made a significant contribution to developing high-density patterns by ion-induced phase transformation. Using low-energy proton irradiation and non-destructive interface control, he showed that magnetic patterns with a pattern size of ~8 nm may be generated in complex magnetic nanostructures (Applied Physics Letters, 111, 152401). His recent article (Advanced Science, 9, 2201749 (2022)) shows the unique pseudomorph interfacial structure of Co/Pd constructed by phase‐transformation of paramagnetic Co3O4/Pd to ferromagnetic Co/Pd superlattices by low‐energy proton irradiation making it possible to induce extraordinarily large orbital anisotropy and strongly enhance spin-orbit coupling (SOC) at the interface, which can be attributed to the strong level of structural inversion asymmetry (SIA) and the substantial in-plane tensile stress built up at the interface between Co and Pd. He also proposed a quick, affordable, and reliable in-house method based on micromagnetic modelling to estimate the characteristics of MTJs in 2017 (Applied Physics Letters, 110, 232401) and 2020 (Nature Scientific Reports, 10, 2799) in response to the challenges of tunnel junction fabrication. He has all-around expertise in growth, characterization of magnetic thin films, and nanostructure along with transport measurements. His capability to develop and measure scientific instruments such as the MOKE microscope/magnetometer (Journal of Applied Physics 115, 043906 (2014)) make him an asset to the organization.
