Dr. Nijo joined the Department of Physics as an Assistant Professor in December 2014. Prior to this, he served in the same capacity at Sacred Heart College, Thevara, Kochi, during 2013–14. Before that, he was a UGC Dr. D. S. Kothari Postdoctoral Fellow at Mahatma Gandhi University, Kottayam. He also worked as a Guest Lecturer at Christ College, Irinjalakuda, for a brief period during 2012–13.
Dr. Nijo obtained his Master’s Degree and Ph.D. in Physics from the Department of Physics, Cochin University of Science and Technology, Kerala, in 2006 and 2013, respectively. He received his Bachelor’s Degree in Physics from Christ College, Irinjalakuda, under the University of Calicut, in 2004.
He is a Life Member of the Academy of Physics Teachers (APT), Kerala, and served as a member of the UG Board of Studies, University of Calicut, during 2023–26.
His research interests include black hole physics, gravitational waves, and dark energy models, while his teaching interests lie in theoretical and computational physics.
Beyond his academic pursuits, Dr. Nijo is actively involved in public outreach and science popularization activities. His hobbies include astrophotography and the creation of science toys.

My areas of research interests are Black hole physics, Gravitational waves and Dark energy models. Black hole’s response to external perturbations will carry significant information about these exotic objects. This response, is dominated by the damped oscillation of the perturbations, called quasinormal modes(QNMs), followed by the tails of decay and is the characteristic of the background black hole spacetime. On the other hand, in the last three decades, several shortcomings came out in the Einstein’s General Theory of Relativity(GTR), mainly due to the observed accelerated expansion of the universe and the failure to achieve a quantum version of gravity. My studies probe the signature of new theories of gravity on the evolution of various field perturbations on the black hole spacetimes. Recently direct detection of gravitational waves from black hole binary system is realized by LIGO team. We hope the information about the fundamental theory can be obtained from the gravitational waves produced by events involving the black hole.
