Abstract In the latest 30 years the research of neutrino physics culminate with the Nobel Prize in 2015 for discovery of neutrino oscillation give us, a signal for New Physics is necessary to understand the different transitions between neutrino flavours. The more economical scenario is the existence of three neutrinos with non-zero mass differences and mixing angles. This scenario can be challenged by New Physics that are still unknown to us. If the New Physics, whether its sterile neutrinos or non-standard interactions or some other exotic model, is small enough such that their effects lie hidden within the current systematic uncertainties of neutrino experiments, then, it may be possible that they induce a bias in the precision measurements of oscillation parameters. It would be interesting to explore if incorporating the existence of New Physics in the theoretical framework along with such nuclear effects can have significant effects on the measurements of neutrino experiments. The effects due to these new features may add up or cancel each other leading to discrepant measurements. In the era of precision measurements at neutrino experiments, a sound understanding of these effects is needed. There is some crucial topics that require our attention prove important in shaping the course of future research in the field of Neutrino Physics, in particular will focus on the existence of light sterile neutrinos and the existence of non-standard neutrino interactions. The existence of light sterile states can signalled a more complex and interesting scenario for the cause of neutrino oscillations. Also non-standard neutrino interactions are not evident at the present but it should be present at some level and the use the best future high precision neutrino experiments is crucial to understand the possible scenarios of neutrino oscillation.
