- PD models for creep and stress relaxation using viscoelasticity and applied it to model the deformation and failure in adhesively bonded single and double lap joints.
- PD models for thermo-oxidative degradation of polymers.

During my doctoral studies at IISc Bangalore, I made significant contributions to the following areas of peridynamics (PD), phase field theory, and gauge theory of solids:
- Developed PD models for plates, shells, and axisymmetric structures to predict fracture and fragmentation.
- Formulated PD plasticity models for axisymmetric structures.
- Formulated phase field theory in the framework of PD to arrive at a continuum damage model.
- Studied delamination of composite structures using phase field based PD theory.
- Investigated inelastic response of ceramics through phase field based PD theory.
- Studied multiphysics problems, e.g. flexoelectricity using PD phase field to investigate nanoscale fracture propagation in solid dielectrics.
- Proposed a general procedure for solving discretized PD continuum and atomic systems using Hamilton-Jacobi theory and time-dependent perturbation techniques.
- Developed a sub-horizon based PD theory to eliminate zero-energy modes from the correspondence framework of non-ordinary state based PD.
- Carried out numerical simulations in PD for impact dynamic problems involving plasticity and damage.
- Formulated a conformal gauge theory of solids and shown how various electro-magneto-mechanical phenomena e.g. piezoelectricity, flexoelectricity etc. can emerge from local symmetry considerations of the Lagrangian.
- Extended the conformal gauge theory by incorporating time which led to Cauchy-Maxwell equations.

During my M.Tech. at IIT Delhi, I analyzed the performance of Chamera dam-reservoir-foundation system (located in Himachal Pradesh, India) under simulated scenario earthquakes using a 3D finite element model in ABAQUS software.
