Teachers guide paths, but a few illuminate and shape lives and Prof. M. F. Wani, Professor (HAG), Department of Mechanical Engineering, NIT Srinagar, is one such exemplary. He officially retired from active service on 30 November 2025.  I feel compelled to share my memories with a man who has been far more than a PhD supervisor- a true mentor, an institution builder, and a rare academic visionary; a vision that guided us,  a mission that shaped us and a memory that never fades. I am honored for having completed my PhD in Ocean Tribology under his esteemed supervision from August 2015 to June 2019. What I learned during those years will continue to define my academic, administrative, and ethical outlook today and always. Among the first echoes of my experience with Prof. Wani was accompanying him to undergraduate and postgraduate classrooms. He actively involved me in teaching and academic discussions, instilling in me the confidence to teach and guide students. More importantly, he emphasised learning beyond theory, applying knowledge to practical engineering problems. This philosophy has remained with me, and today, when I teach, I consciously ensure that students gain practical skills alongside conceptual understanding. I owe this teaching approach entirely to him. Prof. Wani exhibited exceptional work ethic and remarkable diligence.  Long working hours were routine; we often remained in the office until 7 to 8 PM. Despite frequent calls from home, he remained deeply committed to his mission, developing one of the most advanced tribology laboratories in the country and establishing a Central Research Facility Centre capable of matching global standards. Saturdays were never off, and many Sundays were spent in the laboratory. His dedication was not driven by personal gain but by a vision and mission to uplift the research culture of the institute. During my Journey, I got the privilege to assist him in many official tasks, observing how he managed academic administration with integrity and foresight. Prof. Wani held several important administrative positions, including multiple Deanships and served as In-Charge Director of the institute whenever the Director was off-station. He also served as Coordinator for national initiatives such as UBA, TEQIP-III, and PMDP. His diligence and vigour inspired me to pursue a PG Diploma in Educational Management and Administration (PGDEMA), further strengthening my administrative skills. I vividly remember a time when Prof. Wani was on the verge of becoming the Vice Chancellor of a University. His eagerness to serve society at a higher level was evident. He possessed innovative ideas for institutional governance and nation- building. Perhaps destiny had other plans. NIT Srinagar and indeed the entire research scholar community of the institute needed him more. His most enduring legacy lies in the world-class research facilities he established at NIT Srinagar. These include XRD, FESEM with EDS, Sputter Coating Machine, WDXRF, Raman Spectroscopy, Laser Surface Texturing facility, Rheometer, Zeta Potential Particle Analyzer, Nano-mechanical systems for nanocoating analysis, and high-end tribology equipment. For the first time, scholars from almost every university and research institute in the state could access advanced characterisation facilities locally, facilities that earlier required travel outside the state. While these instruments were procured through government funding and are rightfully meant for all scholars and faculty, Prof. Wani always emphasised responsibility, discipline, and a sense of belonging. Unfortunately, I witnessed occasions when sophisticated equipment was mishandled, settings disturbed, and maintenance neglected. Delays and downtime often resulted not from system failure but from misuse. Despite this, one undeniable truth remains: without Prof. Wani’s vision and effort, these facilities would not have existed at all. His contribution has permanently altered the research landscape of the institute. On a more personal note, I vividly remember my first interaction with him after securing admission to the PhD program. His first instruction was clear: avoid daily commuting and stay in the institute’s PG hostel to devote maximum time to research. I followed his advice, spending countless nights in the laboratory along with my lab mates, Dr. Jagtar Singh and Dr. Parveen Kumar. Remarkably, Prof. Wani himself visited the lab late at night on many occasions. We shared tea and discussed research ideas in the quiet hours. Such dedication from a supervisor is rare and such humanity is rarer still. As Prof. M. F. Wani has stepped into retirement from active service, he leaves behind not just laboratories and instruments, but a culture of commitment, excellence and gratitude. Generations of researchers will continue to benefit from his vision, often without knowing the effort that went into building it. For those of us who had the privilege of working closely with him, his legacy is etched not only in infrastructure, but in our professional ethics, sense of responsibility, and commitment to serve society. Beyond his role as a mentor and institution builder, Prof. Wani’s professional stature extends well beyond his home institute. He has served on national level academic and policy platforms, including membership of the National Executive Committee of Unnat Bharat Abhiyan (UBA). He has played a significant role in scholarly publishing as Editor of the reputed journal Discover Nano and as an Editorial Board Member of several leading international journals in the field of tribology and allied areas. Since 2012, he has contributed as an Advisor to the Union Public Service Commission (UPSC), Government of India. His international academic engagement includes serving as a Visiting Professor at Bournemouth University, United Kingdom, and acting as an examiner for numerous international universities, as well as premier national institutes such as IISc and IITs. Such contributions do not retire; they endure.   (The Author is Ph.D. in Ocean Tribology)
