Genomics Technology Development
The Innovation Lab aims to improve the accuracy and expand the scope, scale, and resolution of genomic measurements. We have developed methods for accurate and high-resolution microbiome profiling (see below), methods for large-scale transposable element mapping, and a novel method (REcount) which allows for PCR-free quantification of engineered constructs using Illumina sequencing. We have used REcount to quantify size biases across different Illumina sequencing platforms.
Illumina size standards allow measurement of sequencer-specific size biases. Top) Design of REcount-based Illumina size standard constructs. Each standard construct contains a normalization barcode, as well as a barcode associated with a variable size standard that can be liberated by MlyI digestion and directly sequenced. Left) Raw abundance data for all 30 size standards and normalization barcodes from a MiSeq run. Right) Size bias profiles of the MiSeq (n=6 flow cells), NextSeq (n=4 flow cells), and NovaSeq (n=1 flow cell, 1 lane) sequencers.

The microbiome plays a critical role in human health and disease, as well as the health of our planetary ecosystem. The UMGC Innovation Lab has been working to improve the accuracy and resolution of microbiome measurements. Our contributions include uncovering mechanistic insights into several forms of error and bias in amplicon-based microbiome studies. In these experiments, we also discovered an unexpected phenomenon, editing of the amplification primers during PCR, which can be exploited to expand the set of taxa that can be detected.
In addition, the UMGC Innovation Lab contributed to the development of a highly scalable shallow shotgun sequencing approach for high-throughput metagenomic sequencing, which allows species or strain-level resolution of a microbial community to be obtained for a fraction of the cost of conventional deep shotgun sequencing, enabling dense sampling and increased power and resolution in large-scale microbiome studies.

In addition to research and education, it is the mission of the University of Minnesota to apply our knowledge and discoveries to benefit the people of the state, the nation, and the world. One way that we do this is through technology commercialization. UMGC Innovation Lab scientists have filed multiple patent applications on new genomics technologies that have been developed at the University of Minnesota and have also worked to translate discoveries through company formation.
