The role of quenched disorder in condensed matter ground states has been a subject of intense research over many decades. A subclass of the general problem, commonly known as the problem of elastic media in a random potential, has found application in a variety of systems, e.g., adhesion, friction, wetting and two-fluid interface in porous medium besides many other areas. We perform a random walk in these fields. Our work in the area of soft condensed matter is currently concerned primarily with behavior of soft matter at or near internal or external interfaces. The work focuses on the study of novel systems, novel phenomena and development of novel experimental techniques to study them. Our future work builds upon the work already completed, as described above, as well as newer areas. Some examples are given below:
