Causal models make strong assumptions. In many cases these assumptions cannot be verified even asymptotically. The impact of violations of these untestable assumptions on parameter inference can be severe. My methodological research focuses on building causal models to maximize causal prediction performance, the ability of the model to predict the effects of system interventions. This form of model evaluation is highly robust to violations in model assumptions and directly relevant to many modern biological applications such as cell line perturbation experiments and design of rational combination therapies in cancer. In addition to my methodological research, I collaborate with clinicians and biologists at MD Anderson on projects in cancer early detection, omics data analysis, and clinical trial design. If you are a GSBS, UT Health, or Rice student interested in my research, please contact me.
