Profile Summary

I hold a PhD in Computer Science and Engineering with a strong focus on AI, Machine Learning (ML), and Natural Language Processing (NLP). My research delves into multimodal machine learning, video and image captioning, computer vision, and information extraction. I have over five years of research experience, including postdoctoral work at the University of Oxford, where I focus on deep learning models for asset detection using satellite imagery, NLP-based data extraction, and ML for decarbonization efforts in agriculture. I’ve successfully implemented deep learning frameworks using PyTorch and Keras, and am skilled in handling large-scale datasets and developing models that integrate NLP and computer vision. For example, I designed a retrieval-augmented generation (RAG) pipeline using open-source language models and created ranking systems for more efficient information extraction. My technical proficiency includes programming languages like Python, R, and MATLAB, along with cloud platforms like Google Cloud (GCP) and specialized tools such as LangChain and LlamaIndex. I’ve contributed to cutting-edge projects, including multilingual video captioning and shot boundary detection algorithms, leading to publications in reputable journals. Additionally, I’ve supervised master’s and PhD students, organized workshops, and presented at international conferences on topics such as NLP’s role in climate change solutions and advanced machine learning techniques for sustainable finance.
