I am a data scientist who loves to answer meaningful questions using data. I used to do a lot of statistical analysis, now I spend most of my time developing deep learning models and reinforcement learning algorithms, and utilizing LLM for research. During my PhD years, I was applying machine learning/data mining techniques to the smart grid big data. Now I am collaborating with scientists from various fields (electrical engineers, material scientists, and biologists) to conduct cutting-edge research using AI/ML.

Data ScientistPacific Northwest National Laboratory - Pnnl May 2018 - PresentRichland, Wa, Us1. Applied uncertainty quantification (UQ) methods for deep learning models in predicting electric energy storage material properties and utilized UQ for active learning.2. Used Gaussian process regression (GPR), Bayesian optimization, and large language models (LLM) to automate material discovery.3. Trained reinforcement learning agents for dynamic grid control in a parallel computing environment.4. Used graph neural network (GNN) to detect cyber attacks in power systems.5. Used deep neural network to predict power transmission line overloading and recommend remedial actions in the cascading contingency cases.6. Used convolutional neural network (CNN), long short-term memory (LSTM), and transfer learning to detect high impedance faults in the power system.7. Used CNN and transfer learning to detect eels in the sonar images.
