Recent project: Visualizing Proteomics Data

For this project, I worked with three groups of students to analyze a dataset from the Archaeal Proteome Project (ArcPP, for the halophile archaeon Haloferax volcanii) on properties of proteins, peptides, and their mass spectrometric identification, using data visualization techniques. This work was done in collaboration with Dr. Stefan Schulze (RIT, School of Life Sciences).

Excerpts from student work:

Figure 1: A boxplot and a histogram showing the distribution of PSM (peptide-spectrum match) values for peptides identified in this dataset.

Figure 2: Bubble chart for number of peptides by sequence coverage by total number of datasets

Figure 3: Pie chart showing the propotion of proteins with q-values within the given intervals.
