I have experience
in providing performance insights
through CFD and heat transfer
simulations/ analysis, to enable
design improvements for a wide
range of applications. My strengths
are understanding stake-holder
high-value problems, streamlining
them into simulation requirements,
and adopting Systems Engineering
principles in integrating
Computational Modeling with product
development and real-time system
diagnostics and control. I am a quick and continuous learner,
interested in exploring and adopting
innovative, hybrid modeling
techniques for application based
R&D/engineering. 

Aug 2020 - Present : Computational Modeling Engineer - Applied Materials, Bangalore, India 

• Achieved real-time system diagnostics/control & optimized prod-
  uct development cycles by building state-of-the-art Thermal Dig-
  ital Twins (DTs) for semiconductor manufacturing processes.
• Supporting hardware development through 2D and 3D CFD simulations
  to study heat transfer, flow and reactions in improving energy ef-
  ficiency, gas delivery system design and chemical deposition for
  chip manufacturing.
• Developed Hybrid Modeling techniques for DTs- Physics Based
  Network Models for Heat Transfer between different chamber
  components, Modeling Surface-2-Surface Radiative Heat Transfer
  using 3D View Factor Calculations, Statistical/Regression Based
  Models for faster real-time digital virtual simulation response. Re-
  duced Order Models for better turnaround times (In Progress). 
• Achieved within 2% accuracy using DT results in comparison with
  real-time transient on-field data. Scripting & automating data
  exchange between different hybrid models. Integrating simula-
  tions with real-time Sensor input data, to provide live actionable
  insights and improve process efficiency/yield.
