👋 Hi, I'm Todd!

It’s nice to meet you! I lead a team of bioinformatics analysts at the University of Minnesota Supercomputing Institute. We use advanced DNA and RNA sequencing technologies to investigate immune cell dynamics, mechanisms of cancer, and pathogenic variant detection in patient samples. I collaborate with many cross-functional teams to analyze and interpret these datasets, resulting in high-impact publications or clinical diagnosis.
