During my doctoral thesis, for numerical model of bending (Quasi-static) on wood based eco-sandwich structure, I have used an ABAQUS (Implicit) to develop and calibrate the whole model. For dynamic Impact model of the same sandwich structure, I have used a LS-Dyna (Explicit) to develop and calibrate the numerical model for impact behaviour.

Post-doctoral work:

• MODERN METHODS OF CONSTRUCTION (MMC): Joined from 1st of August 2025 as Senior Research Fellow to work in the role of Co-investigator for the research project entitled: CREATION OF STANDARDIZED DESIGN DETAILS FOR THE MODERN METHODS OF CONSTRUCTION (MMC) BUILDS - funded by the Enterprise Ireland (Construct Innovate) - Ireland and the Sustainable Energy Authority of Ireland through University of Galway, Galway - H91 TK33, Ireland. 

• DECOST: DEVELOPMENT AND CHARACTERIZATION OF HIGH-PERFORMANCE COMPOSITE ECO-STRUCTURE - First research project as Principal investigator - funded by the Ministry of science, technology and innovation, Spain via University of Carlos III Madrid, Spain for the three years (10/2021 – 10/2024) and successfully developed project outcomes. During this project, I successfully developed numerical model using constitutive elastic-plastic material models in the form of sub-routine (VUMAT) implemented in ABAQUS-Explicit to predict progressive damage accurately in impact as well as dynamic bending response of composite eco-structure.
