baker hughes
Data Scientist in Non Destructive Testing
• Involves the creation of algorithms and models to recognise, classify and size features using near field acoustic waves. • Acquisition, processing, analysis and preparation of structured and unstructured acoustic data from inline inspection tools. • Created a tool to simulate and mitigate acoustic cross talk. • Created algorithms to quickly and automatically extract and classify acoustic data reducing manual effort by a factor of 10. • Plan and execute experimental measurements to understand acoustic phenomenon for the development of new in-line inspection techniques. • Collaborate with Quality, Operations, Analysis, Software and Mechanical teams to identify and resolve potential issues. • Involved as an Acoustics specialist in the development of Machine learning models. • Developing a Phased Array based in-line inspection tool.

cea commissariat lnergie atomique et aux nergies alternatives
PhD in Acoustic Physics
Ultrasonic guided wave simulation and defect localisation and imaging • Created an acoustic simulation tool to simulate acoustic guided wave propagation in tubular structures. • Tool reduces computation times by a factor of 15-20 and is to be implemented in an industrial acoustic simulation software (CIVA). • Developed an experimental test rig to validate the simulation tool. • Helped develop and implement a mathematical model to simulate acoustic emissive sources. • Implemented an imaging algorithm in the context of wave propagation and acoustic emissions to identify and localize simulated and real defects using concepts from SHM and NDT.

Acoustic resonance based de-icing - Master thesis
De-icing using low frequency Acoustic resonance • Research on the proof of concept of de-icing aerospace structures (metallic and carbon fibre) using low frequency acoustic resonance. • Performed modal and frequency response simulations on ANSYS to understand the behaviour of the ice-structure interface. • Utilized a specialized wind tunnel to "ice" surfaces and to perform de-icing tests. • Created a manual for the electro-mechanical multi-physics module of ANSYS to implement Piezo-actuators using APDL command snippets.

Aeroelasticity - Internship
• Performed a Validation study of the Fluid Structure Interaction capabilities of LS-DYNA using the Smoothed Particle Hydrodynamics module. • Involved a qualitative study of the concepts of Aeroelasticity and the SPH module of LS-DYNA to simulate various Aeroelastic responses.
2014 - 2014
airbus
Structural Design project - ISAE and Airbus
• Designed a detailed cross-section of a fuselage based on the Airbus A320. • Performed structural dynamics, fatigue, damage tolerance, buckling, cost and weight analysis.
2013 - 2013
aeronautical development agency
Aerodynamic optimization - Bachelor thesis
• Performed aerodynamic analysis, validation and optimization of air flow through the RAE M2129 S-duct air-intake for various Mach numbers. • Used CATIA to model the duct, ANSYS ICEM CFD for model discretization and VISP3D (An in-house solver) for simulation.
2012 - 2012
genser aerospace it pvt ltd
Structural design - Internship
• Preliminary Structural design of the VLJ-3X1. • Performed stress calculations and dimensioning of the Frames, Longerons and Bulkheads of the fuselage and the Spar design of the wing.
2011 - 2012
manipal institute of technology
University UAV Design - Team lead Structures
• Team lead of the Structures Sub-system of the University’s Unmanned Aerial Vehicle design team which took part in the SAE Aero Design competition at California. • Designed and validate the Structural framework of the UAV by numerical simulations, calculations and experiments in collaboration with Aerodynamic, Propulsion and Flight dynamics teams. • Involved in the manufacturing and assembly of the UAV.
