Shivam Agarwal
I am
a graduate student at University of Illinois at Urbana-Champaign (UIUC) where I study CS and AI.
Previously, I was an Engineer at Cisco and a research intern at IIIT-Delhi and Vanderbilt University.
I obtained my bachelors degree in ECE from Manipal Institute of Technology, India.
I am especially passionate about machine learning, natural language processing, and graph-based deep learning. I have been fortunate to contribute to a wide range of research directions, including large language models, text mining, text representation learning, spatio-temporal information processing, reinforcement learning, quantitative finance, and computational social sciences. I would be happy to discuss any project idea at the intersection of the above areas; feel free to reach out if you are interested!

Research
I'm interested in natural machine learning, and natural language processing. Recently, I have been working on making language AI more efficient and accessible. I am evaluating and improving large language models' reasoning capabilities, factuality, and trustworthiness.
