Profile Summary

I hold a PhD in Pavement Engineering from the Indian Institute of Technology Guwahati, with expertise in asphalt materials, pavement design, and performance evaluation. My research emphasizes sustainable pavement technologies, focusing on the use of waste materials in asphalt binders and mixtures, as well as rheological, chemical, and microstructural characterization of binders through advanced testing methods. I have authored and co-authored over 80 peer-reviewed international journal papers, book chapters, and conference proceedings, and actively serve as a reviewer for leading journals published by ASCE, Elsevier, and Springer Nature. Currently, I am a faculty member at the National Institute of Technology Sikkim, where I contribute to teaching, curriculum development, and the creation of online instructional content and MOOCs. My work has been presented at numerous national and international forums, and I have collaborated with industry on projects related to pavement performance and road safety. My contributions have been recognized with the prestigious Bihar PWD Medal from Indian Roads Congress (IRC, 2024), the National Road Safety Competition award (2021), and multiple best paper and presentation awards.
