Tanwi Mallick, PhD.

Tanwi is an assistant computer scientist in the Mathematics and Computer Science Division at Argonne National Laboratory, where she previously held a postdoctoral appointment. Her research is primarily focused on spatiotemporal graph neural networks, uncertainty quantification, trustworthy scientific machine learning (SciML), foundation models, natural language processing, and high-performance computing. She also has experience working across various scientific domains, such as transportation systems, climate science, and HPC network analysis. Before her tenure at Argonne, she was a senior data scientist at General Electric. Tanwi obtained her Ph.D. in computer science from the Indian Institute of Technology, Kharagpur, India.
