Research

My general research interests are in the broad field of artificial intelligence (AI), where I focus on machine learning (ML) and scientific computing (SC) with their applications, e.g., engineering design. My goal is to combine data-driven ML and physics-based SC to create novel hybrid methods that combine both advantages and, most importantly, bring them to solve practical problems more efficiently and effectively.

I made a video talking about my research ( [Slides] [Video]) in details. It covers the following topics:

  1. Machine Learning for scientific computing

    1. Data-driven Spatial-Temporal Field Modeling

      1. Conservational kernels

      2. Meta-learning in multi-task and spatial-temporal problems

      3. Uncertainty quantification with large spatial fields

    2. Multi-fidelity fusion

    3. Machine Learning for Design and Optimization

      1. Multi-Fidelity Bayesian optimization

      2. BO with uncertainty, e.g., yield optimization

      3. Mix-variable (Ordinal categorical continuous variables) Bayesian optimization

    4. *Reduced order model (ROM) with data-driven methods

  2. Scientific computing for machine learning

    1. Physics enhanced Bayesian models

    2. Machine-learning-injected Simulations

    3. Denoising Diffusion Probabilistic Models

  3. Machine Learning + scientific computing for Industry

    1. Digital twins

    2. Algorithm development for SPICE acceleration, thermal optimization, yield analysis and optimization in 3D integrated circuit (with EDA software industry)

    3. Signal processing and system identification algorithm development for a micrometer laser doppler vibrometer (with scientific equipment industry)

    4. Algorithm development for magneto-optic Kerr scope automatic dynamics capturing (with scientific equipment industry)
