Re-Post-My Department and our endeavors


The Department was established in the year 1970 under the Faculty of Science.  Dr. K. S. Viswanathan, eminent theoretical Physicist and student of Nobel Laureate Sir C. V. Raman, was the founder Head of the department. The Department started functioning with a UGC sponsored Post M.Sc Diploma Course in Space Physics, with 7 students and a few research scholars. From the modest beginning, it has grown into one of the largest and most bustling centres of academic activity.  The department has received support from DST under the FIST programme.  At present the department offers M.Sc., M. Phil and Ph.D programmes in Physics.


 Our Endeavors

The current focus of my research is on understanding and exploiting the dynamics of oxide ion conductivity of complex ceramic oxides. In particular, I am interested in development of dynamics of oxygen ions at micro scales of ceramic oxides.  At small scales, microstructures variations produce fantastic tailor made properties in IT SOFCs which have a very important part to play in next Generation Fuel Cells. An Impedance Analyzer features as the main characterization tool since optimization of characterization of oxide ion conductivity is mainly dine in frequency range limited to few mHz to MHz. At such frequencies, we need to pay attention to phenomena generally ignorable at macro scales. The need for realising very high oxide ion conducting electrolytes leads to careful study of power enhancement of Solid Oxide Fuel cells. In recent times, I have devoted considerable effort on advancing the current understanding of pyrochlore structured complex ceramic oxides focusing on how they behave in different atmospheric conditions. I have also initiated works related to Non Linear Optics following the legacy of my dear teacher Dr. C I Muneera. In NLO lab, we have studied several aspects of Non Linear Behaviours or organic as well as inorganic samples producing interesting results in Micro electromechanical devices (MEMs) Last but not least we continue to explore intrinsic properties of some conventional organic material using Z-scan techniques. In addition, I am also interested in astronomy, sundials, sky observations and universe modeling. In particular, I am interested in developing computational tools and techniques that help in modeling phenomena at astronomical scales.

I was delighted to deliver a talk at Sree Narayana College, Varkala, as part of the TRENDZ Seminar Series 2025 organised by the PG Department of Physics. Speaking on “2D Materials for a Sustainable Energy Future” , I had the opportunity to introduce students and faculty to the fascinating world of ultrathin materials, their role in next-generation fuel cells, and how they tie into the broader vision of sustainable development. We discussed why 2D materials are considered the future-high surface area, tunable properties, and exceptional catalytic behaviour-while also reflecting on the challenges such as large-scale fabrication, stability, and commercialization. The interaction was warm, thoughtful, and energetic, and it was wonderful to see the enthusiasm of the students during their paper presentations. Sharing a few photos from the session, grateful to Smt. Malu for the invitation and the enriching academic atmosphere. Duty Certificate Link to drive On 18 November 2025 , I had the opp...

A Moment of Grace and Responsibility In the sacred silence of a church, we often see a priest standing before the congregation. He may not always be the wisest, the most talented, or the most scholarly in the scriptures. Yet, once chosen to stand in that space, he carries a responsibility, not of perfection, but of presence. He becomes a vessel, entrusted to speak, to guide, and to serve. These words, shared by Nazeeb Sir, deeply resonate with me. Today, I stood before an august gathering that included the respected IQAC Director and faculty members from across the University, not as the most accomplished, but as one entrusted with a message. It is not position, but purpose that calls us to speak. And when chosen, we must honour that moment with humility and readiness. The occasion was the One-Day Workshop on Content Creation on SWAYAM Platform , organized by the Internal Quality Assurance Cell (IQAC), University of Kerala, held on 20th June 2025 at CLIF, Kariavattom Campus . I had the...

🌟 Kudos to Dr. Rakhi R. B., our proud alumna of the Department of Physics, University of Kerala. She has once again made it to the Stanford University-Elsevier “Top 2% Scientists of the World” list, based on the August 2025 update of the Ioannidis standardized citation database (DOI: 10.17632/btchxktzyw.8). This recognition covers both career-long impact up to 2024 and single-year citation influence for 2024, highlighting her global standing in nanomaterials and energy research. 👏 What makes this truly remarkable is that it is the 6th consecutive year she has retained her place in this prestigious global list, reflecting sustained excellence, consistent contributions, and leadership in research. Kudos to Dr. Rakhi for bringing such glory. We are all proud of her achievements and wish her continued success in her scientific journey. 🌹✨ The Stanford–Elsevier Top 2% Scientists of the World (2025 update) has once again brought pride to the University of Kerala with the inclusion of two...
