Tarak Nandi is an Assistant Computational Scientist in the Data Science and Learning division at Argonne. He works at the intersection of computational genomics, cancer biology, high performance computing (HPC) and artificial intelligence (AI).

His work primarily focuses on:

• accurate and rapid identification of structural variants (large genomic alterations disrupting gene expression or function) in human genomes,
• accelerating genome-wide association studies to identify correlations between genomic variations and phenotypes from large genomic databases, with a focus on precision medicine
• understanding gene networks from single cell RNA-seq data using large language models to identify potential drug targets in the context of cancer biology (currently for head and neck squamous cell carcinoma, and CHIP, a precancerous blood condition)
• multimodal deep learning using imaging and multiomics data for elucidating the mechanisms underlying the impact of low dose radiation on cancer initiation and progression.

He is a member of the NIH/NCI Virtual Human Global Initiative, the AMIA complex variant working group, and the TOPMed structural variant calling working group.

His past experience includes fundamental and applied research in unsteady aerodynamics, turbulent/transitional flows, atmospheric boundary layer flows using Computational Fluid Dynamics (CFD). He is also experienced in developing deep learning models for gas-solid multiphase flows and reacting flows, and generation of synthetic turbulence signals.
