Postdoc, AI/ML Researcher
About
I am a postdoc at Los Alamos National Laboratory with a PhD in Computer Engineering from the University of Maryland Baltimore County and with both academic and internship experience in developing explainable deep learning modules for audios and images as well as their deployment on embedded devices. Specialties include but are not limited to Python, MATLAB, C Programming, TensorFlow, PyTorch, and Verilog. Previously, I worked as an intern at Infineon Technologies with a focus on building transparent and interpretable AI models. Current research interests focus on hardware-aware fine-tuning of DNNs, explainable AI, compression techniques for Embedded AI, and AI/ML for vision, audio, time-series, environmental and healthcare applications.
