Work Experience
Senior Research Engineer
Dolby Laboratories
- Developed a space- and time-efficient denoising and super-resolution method that significantly reduced processing time while enhancing image clarity.
- Engineered a TPB-based compression method that lowered storage requirements while maintaining high video quality.
- Pioneered a new 360 video codec that improved streaming efficiency and decreased latency in real-time applications.
- Spearheaded floor plan construction for multiple perspective videos using object-based latent vector aggregation, enhancing reconstruction accuracy and performance.
- Implemented advanced deep learning models for time-series forecasting (RNN, LSTM, GRU, CNN, and Transformer-based models), achieving improved accuracy through metrics like MAPE, RMSE, MAE, SMAPE, R², and log loss.
- Gained insights into EV charging trends through industry research, analyzing factors like time of day, weather, and location while identifying grid management challenges.
Experience
PhD Thesis
Working under the guidance of Professor Edward J. Delp in the video and image processing (VIPER) laboratory, I created advanced detection algorithms that included a fusion-based method for forensic splicing localization and a data-driven approach for panchromatic imagery copy-paste localization. By integrating state-of-the-art techniques such as vision transformers, deep belief networks, and nested attention U-Nets, I enhanced manipulation detection capabilities and set new benchmarks in digital forensics research. My work has been featured in prominent conferences, including SI22 SPIE Defense + Commercial Sensing, CVPRW, and the International Conference on Acoustics, Speech, and Signal Processing, highlighting its impact on advancing the field.
