Welcome from the Chair

                                                               The Physics Programme at IISER Pune is built on the twin pillars
                                                               of research and education, in keeping with the overall philosophy of
                                                               IISER. We see this as a mutually beneficial arrangement for faculty and
                                                               students alike.
                                                                 Faculty members find it invigorating to have strongly motivated
                                                               students participating in their laboratory-based or theoretical research.
                                                               Students, in turn, benefit from the strong research background of their
                                                               teachers, who bring a confident and modern understanding of their
                                                               subject to the classroom and the teaching laboratory. The involvement of
                                                               undergraduates in research work, often leading to publications, is a key
                                                               feature of IISER’s programme.
                                                                 Our programme is still youthful. It is in a phase where strengths are
                                                               being consolidated and plans starting to bear fruit. Our research goals
                                                               span all the profound and challenging questions in physical science,
                                                               from the micro-world to the cosmos. We are equally at home pursuing
                                                               fundamental principles of long-term relevance and seeking solutions
                                                               with a more immediate social impact. Rather than compartmentalising
                                                               our programme, we emphasise the unity of all of physics and encourage
                                                               research across traditional boundaries.
                                                                 Over the next decade, I am confident that we will be seen as a leading
                                                               player in Indian and global science, and a force to reckon with.
