AI & Energy expert at NVIDIA

I am an AI & Energy expert at NVIDIA, spearheading the development and implementation of artificial intelligence solutions across the energy sector.

My expertise lies in building industrial agentic AI systems and domain-adaptive Large Language Models that transform operations in oil and gas and renewable energy industries. I also spent impactful time developing HPC CUDA applications for exploration geohysics.

With a strong research foundation and industry experience, I drive end-to-end AI projects that bridge the gap between theoretical advancements and real-world impact. My work focuses on creating AI solutions that enhance decision-making, optimize operations, and accelerate the energy transition through innovative applications of generative AI and high-performance computing.

Recent research

  • Multi-task learning for low-frequency extrapolation and elastic model building from seismic data

    Acquiring low-frequency data is challenging in practice for active seismic surveys. We propose to jointly reconstruct low-frequency data and a smooth background subsurface model within a multi-task deep learning framework. IEEE Transactions on Geoscience and Remote Sensing, 2022

  • Direct domain adaptation through reciprocal linear transformations

    We proposed a general method for domain adaptation which blends features from source and target datasets by a set of linear operations such a cross-correlation and convolution. We explore the viability of the approach by transferring knowledge from training on gray-scale MNIST dataset to colored MNIST-M dataset. Frontiers of Artificial Intelligence, 2022

  • Deep Learning for Seismic Data Reconstruction: Opportunities and Challenges

    Research project from my internship in CGG, Crawley, UK. Under supervision of Song Hou I explored benefits and pitfalls of using GANs for seismic data reconstruction. In the nutsell, high perceptual realism of reconstructed seismic data is not sufficient for real-world application. Physics also should be constrained. First EAGE Digitalization Conference and Exhibition, Nov 2020

  • Extrapolating low-frequency prestack land data with deep learning

    In synthetic framework we explore capability of a simple neural network to reconstruct low-frequency components of land data. SEG Technical Program Expanded Abstracts 2020

  • Style transfer for generation of realistically textured subsurface models

    We apply an iterative style transfer approach from image processing to produce realistically textured subsurface models based on synthetic prior models. These realistically textured models to be used in training datasets for machine learning applications in geophysics. Presented in Sep 2019, on SEG Annual meeting in San Antonio, USA
