1. Aspects of QFT with boundaries and D-branes
Abstract : Modern string theory is a rich framework which goes beyond standard quantum field theory. There is a belief that at low energies string theory reduces to the Standard Model and Einstein's gravity. In the last years we have learned that there exist different descriptions of the same physics, containing both strings and other extended objects. READ MORE

2. Going Round in Circles : From Sigma Models to Vertex Algebras and Back
Abstract : In this thesis, we investigate sigma models and algebraic structures emerging from a Hamiltonian description of their dynamics, both in a classical and in a quantum setup. More specifically, we derive the phase space structures together with the Hamiltonians for the bosonic two-dimensional non-linear sigma model, and also for the N=1 and N=2 supersymmetric models.

3. Dynamics of Discrete Curves with Applications to Protein Structure
Abstract : In order to perform a specific function, a protein needs to fold into the proper structure. Prediction the protein structure from its amino acid sequence has still been unsolved problem. The main focus of this thesis is to develop new approach on the protein structure modeling by means of differential geometry and integrable theory. READ MORE

4. Twisting and Gluing : On Topological Field Theories, Sigma Models and Vertex Algebras
Abstract : This thesis consists of two parts, which can be read separately. In the first part we study aspects of topological field theories. We show how to topologically twist three-dimensional N=2 supersymmetric Chern-Simons theory using a contact structure on the underlying manifold. READ MORE

5. Twisting it up the Quantum Way : On Matrix Models, q-deformations and Supersymmetric Gauge Theories
Abstract : The mathematical framework which quantum field theory constitutes has been very successful in describing nature. As an extension of such a framework, the idea of supersymmetry was introduced. This greatly simplified the mathematical description of the theories, making them more tractable. READ MORE
