About

I am a Gas Turbine Combustion and CFD specialist with over 16 years of experience applying physics-based simulation to support the development, analysis, and optimization of combustion systems across aerospace and power-generation applications. Throughout my career, I have worked across product development, technology consulting, customer engagement, and simulation methodology development with organizations including Siemens, ANSYS, and Honeywell. My experience spans the use of advanced computational techniques to understand complex interactions between fluid flow, turbulence, heat transfer, chemical reactions, sprays, and emissions, enabling informed engineering decisions and improved product performance. My areas of expertise include: • Gas Turbine Combustion • Computational Fluid Dynamics (CFD) • Multiphysics Simulation • Combustion Modeling • Turbulence Modeling (RANS & LES) • Reacting Flows • Emissions & Combustion Performance Analysis • Heat Transfer & Thermal Management I have extensive hands-on experience with industry-leading simulation tools, including ANSYS Fluent and Simcenter STAR-CCM+, supporting the analysis of turbulent reacting flows, combustion systems, thermal-fluid problems, and Multiphysics applications. Over the years, I have contributed to the development and evaluation of gas turbine combustion systems by investigating critical aspects of combustion performance, operability, emissions, thermal behavior, and simulation accuracy. My work has supported engineering teams in improving design confidence, reducing development risk, enhancing simulation methodologies, and reducing dependence on costly experimental testing. In addition to technical contributions, I have experience collaborating with global engineering teams, customers, and cross-functional stakeholders. During my tenure at ANSYS, I partnered with customers to solve challenging engineering problems using simulation-driven approaches, delivered technical training programs, conducted proof-of-concept studies, and helped organizations maximize the value of engineering simulation technologies. I am passionate about applying computational science to solve challenging real-world engineering problems, mentoring engineers, developing robust simulation methodologies, and advancing the use of simulation to drive innovation in energy and propulsion systems. I particularly enjoy working on complex combustion problems where physical understanding, engineering judgement, and simulation come together to support sound engineering decisions.
