Introduction

The Innovation in Engineering Award recognizes researchers whose work connects fundamental mathematics with engineering applications. Sarabindu Dolui’s doctoral research at the National Institute of Technology Andhra Pradesh examined the controlled manipulation of domain wall motion in notched ferromagnetic nanostrips, strain-induced magnetization dynamics in bilayer heterostructures, and magnetization stability criteria in network systems [4]. The theoretical framework relies on the generalized Landau–Lifshitz–Gilbert equation in the ultrafast regime, where inertial effects become significant [3]. This interdisciplinary orientation spans physics, materials science, electronics, and nanotechnology, and forms the basis for the award assessment presented here [2].

Sarabindu Dolui is Assistant Professor in the Department of Mathematics, School of Engineering, Dayananda Sagar University, India. He completed a Ph.D. in Mathematics at the National Institute of Technology Andhra Pradesh in 2025, with a thesis titled Mathematical Investigation of Ultrafast Magnetization Dynamics in Ferromagnetic Nanostructures. Earlier qualifications include a Bachelor of Education from Batindra Latika B.Ed & D.El.Ed College (WBUTTEPA) in 2021, an M.Sc. in Mathematics from Banaras Hindu University in 2018, and a B.Sc. in Mathematics, Physics and Computer Science from Ramakrishna Mission Residential College (University of Calcutta) in 2015 [1]. His declared research interests include micromagnetic modeling, mathematical physics, dynamical systems, nonlinear dynamics, and machine learning [4].

Academic achievements include All India Rank 491 in IIT-JAM (2015), qualification in NET-LS in 2019 (AIR-76), All India Rank 421 in IIT-GATE (2021), and a UGC-Junior Research Fellowship with AIR-136 in 2021. He received Silver Medals in the NPTEL courses Noc21-ma56 and Noc21-ma46 in 2021 [2]. Documented recognition includes a Swami Vivekananda Merit-cum-Means Scholarship from the Government of West Bengal (2010), a SIAM Student Travel Award for the SIAM Conference on Control and Its Applications in Philadelphia (2023), a Best Poster Presentation Award at the International Conference on Perspectives in Nonlinear Dynamics at IIT Madras (2023), a MI&T Congressi travel grant for the International Conference on Magnetism in Bologna (2024), Overseas International Conference support from NIT Andhra Pradesh for the 14th AIMS Conference in Abu Dhabi (2024), International Travel Support from ANRF for the Joint MMM-Intermag Conference in New Orleans (2025), a CSIR Foreign Travel Grant for the 14th AIMS Conference (2024), and an IEEE Magnetics Society TMRC travel grant for the Magnetic Recording Conference at Tohoku University (2025) [2].

Research Contributions

The central contribution is a mathematical treatment of ultrafast magnetization dynamics in ferromagnetic nanostructures using the generalized Landau–Lifshitz–Gilbert equation with inertial and nonlinear dissipative terms. Studies have examined domain wall depinning in notched ferromagnetic nanostrips and the combined roles of inertial damping, Rashba effect, and dry-friction dissipation [5]. Related work addresses strain-induced domain wall motion in bilayer composite and hybrid piezoelectric-magnetostrictive structures [6], and strain-induced ultrafast magnetization dynamics in cubic magnetostrictive materials [3]. A further line of inquiry develops neural network frameworks for modeling Landau–Lifshitz–Gilbert dynamics, linking micromagnetics with machine learning methods [4].

Publications

The publication record comprises 11 indexed Scopus documents, including journal articles in Advanced Theory and Simulations, Engineering Applications of Artificial Intelligence, International Journal of Engineering Science, Chaos: An Interdisciplinary Journal of Nonlinear Science, Zeitschrift für angewandte Mathematik und Physik, Physica Scripta, Acta Mechanica, Acta Mechanica Sinica, and Mechanics of Advanced Materials and Structures, alongside a book chapter with Central West Publishing, Australia [1]. Representative indexed items include work on domain wall dynamics in cubic magnetostrictive materials [6], strain-induced fast domain wall motion in hybrid structures [7], and strain-induced ultrafast magnetization dynamics with inertial effects [3].

Research Impact

Scopus records 54 citations, 11 documents, and an h-index of 5, while Google Scholar reports 62 citations, 13 documents, and an h-index of 5 [1]. These indicators are moderate in absolute terms but consistent with an early-career researcher publishing in established mathematics, physics, and engineering journals. Citation activity is concentrated in micromagnetics and applied mathematics, indicating a coherent rather than diffuse research program [2]. The interdisciplinary character of the work broadens its potential readership across physics, materials science, electronics, and nanotechnology [4].

Award Suitability

In relation to the Innovation in Engineering Award associated with the Popular Engineer Awards, the candidate presents a documented record of peer-reviewed publication, competitive national fellowships, and international conference participation [2]. The research combines mathematical rigor with engineering relevance, particularly in spintronics and magnetic nanostructure applications [5]. Award criteria commonly emphasize originality, measurable scholarly output, and demonstrable contribution to an applied field; the available metrics and the interdisciplinary scope of the work are consistent with these criteria [1]. No exaggerated claims are made, and suitability is assessed solely on indexed evidence [2].

Conclusion

Sarabindu Dolui’s profile reflects an early-career mathematical researcher working at the interface of micromagnetics, nonlinear dynamics, and engineering applications. The Scopus record of 11 documents, 54 citations, and an h-index of 5, together with Google Scholar figures of 62 citations and 13 documents, provides a verifiable basis for award evaluation [1]. On the evidence presented, the profile is consistent with the scholarly expectations of the Innovation in Engineering Award [2].
