Previous Experience
- Postdoctoral Appointee, Argonne National Laboratory, Lemont, IL
- Designed deep/transfer learning models (Convolutional Neural Networks) for classification, regression, anomaly detection and feature extraction on electron microscopy/spectroscopy.
- Developed smart imaging and dynamic sampling methods using both supervised and unsupervised learning to reduce acquisition time and radiation for scanning imaging modalities.
- Applied convolutional auto-encoders, generative adversarial networks (GANs) and neural style transfer for electron microscopic image synthesis using parallel and distributed GPUs processing.
Graduate Research Assistant, Northeastern University, Boston, MA
- Designed classification (SVM, Neural Networks) and regression (Least-square, Lasso, Ridge, Bayesian) models for x-ray scattering data to recognize shape and size of macromolecules.
- Developed clustering and image processing algorithms to analyze XRD images of biological tissue - feature selection, dimensionality reduction, pattern matching and spectral clustering.
- Applied data quantization, pair-distance function and Fourier method to simulate diffraction patterns of macromolecules and to build dictionary for parameter estimation of measurements.
- Developed image analysis and pattern recognition algorithms for components detection as well as contaminants and artifacts on AFM images of hard drive recording heads.
- Developed computer vision and machine learning algorithms for automatic defect classification on SEM images of semiconductor wafer - edge detection, segmentation in C++.
