Morgan became interested in the field of computational biology while working with Professor Lloyd Smith at the University of Wisconsin. Her work focused on the basecalling problem for automated DNA sequencing. A flexible and modular system was developed called BaseFinder, the first program to introduce confidence values on basecalls. In addition, she worked on projects such as automated muli-component determination, dye-encoding schemes to improve throughput and accuracy, and methods for improved trace processing.

In 1998 Morgan joined Ray Gesteland and John Atkins at the University of Utah as a post-doctoral researcher. There she worked to improve targeting efficacy in the analysis of oligdeoxynucleotides, and then turned her focus on development of new computational and bionformatics tools for proteomics. She developed the Genome Fingerprint Scanning system, designed to identify the coding loci of proteins directly within a raw, unannotated genomic sequence. She also guided the development of PROCLAME, the first tool for de novo exploration of possible post-translational events that modify the masses of intact proteins measured by electrospray mass spectrometry.

The Giddings Lab’s general interest is in improving the functional understanding of how genomes encode diversity in the encoded proteome. The lab continues an ongoing development of tools for the interpretation of mass-spectrometry based proteomics data, including improved MS/MS database search accuracy, improved peptide mass fingerprint accuracy using peak height statistics, and integration of bottom-up with top-down proteomic data sets. Additional projects include cancer biomarker research, and an examination of antibiotic drug resistance in E. coli and P. aeruginosa using a systems biology approach.
