    Research Overview

    I develop AI/ML approaches to decipher the link between molecular features and cellular phenotypes. By combining generative AI (autoencoders, diffusion models, and generative adversarial networks) with emerging single-cell experimental technologies, I aim to build predictive models of how cells will respond to genetic and chemical perturbations. Additionally, I perform experiments on iPS-derived neuron models to better model and treat neurodevelopment and neurological disease.

    A Welch lab publication is recognized in Molecular Systems Biology with a cover design

    A Welch lab publication is recognized in Molecular Systems Biology with a cover design The Welch lab developed PertubNet, a generative AI model that can predict shifts in cell state—changes in overall gene expression—in response to multiple types of unseen cellular perturbations, including responses to drugs. This tool was published in Molecular Systems Biology (Volume 21, Issue 8, 4 August 2025.) and was recognized with the opportunity to design the cover of the journal.

    Thomas Chen, M.S.: From U-M to Harvard/MIT

    Thomas Chen, M.S., graduated in Spring 2025 from the Gilbert S. Omenn Department of Computational Medicine and Bioinformatics (DCMB) with a Master's in Science degree. He started his bioinformatics studies at U-M as a senior student majoring in Microbiology, and attended DCMB’s Accelerated MS program. In June 2025, he will pursue his training to become a scientist-physician at the Harvard/MIT MD-PhD Program.
