During my time at Fred Hutch with Erick Matsen in the computational biology department, I worked on several research projects, leading to a number of academic publications. Much of this research has revolved around the interactions between viruses and the human immune system, as well as patterns of transmission between species and host populations.

Through the course of most of this research, I was deeply involved in the scientific process together with our biological collaborators, helping write most of these papers, and producing a number of data visualizations, some of which are showcased below, next to the papers in which they were published.

Many thanks to the wonderful biologists I have had the pleasure of working with, for their fantastic work, and for the fruitful collaborations they sought fit to work together on.

Deep sequenced B-cell receptor processing

My primary contribution towards this project has been a set of software which our biological collaborators used to process and analyze these datasets.

Interspecies transmission patterns of Astrovirus

In this study, we looked at the first ever genetic sequencing of Astrovirus in non-human primates (NHP), and found evidence of very high interspecies transmission rates to and from NHP suggestive of high susceptibility to the virus.

Monkey to human zoonoses of Simian Foamy Virus

One of the first projects I cut my teeth on as a computational biologist was looking at fascinating data set of genetic sequence data from SFV infected humans and monkeys. The richness of the dataset warranted multiple papers, each of which looked at a certain angle of what the information was able to provide. One of the more major contributions of the work was finding evidence of the human viral restriction factor APOBEC3 as playing a role in the SFV's apparent inability to be transmitted between humans.
