Tanushree received her Master degree in Physics from University of Calcutta, India. As a graduate student, she was deeply motivated by the fascinating world of astro particle physics and decided to continue her research in this field. She pursued her research interest by moving to the Physical Research Laboratory, Ahmedabad. She later earned her doctorate degree working on the phenomenology of particle dark matter models. She is currently working as an Assistant Professor in Physics in the Department of Science and Humanities at Indus University, Ahmedabad, India. Her primary research fields are supersymmetry, physics beyond Standard model, dark matter and neutrino physics. Dr Basak has published several research papers and conference proceedings articles in peer reviewed international journals.

In the field of particle and astrophysics one of the major unresolved problems is to understand the nature and properties of dark matter, which constitutes almost 80% of the matter content of the universe. This book gives a pedagogical introduction to the field of dark matter in general, and in particular to the model building perspective. Starting from the evidence and need for dark matter, it goes into the deeper understanding of how to accommodate a dark matter candidate in a particle physics model. This book focuses on teaching the basic tools for model building of dark matter, starting from the easiest and gradually progressing to the most difficult. Although there are plenty of dark matter models available, this book concentrates on the important ones. It aims to motivate the reader to propose a new dark matter model complying with all observational constraints.
