Hi, I'm Austin Marshall.

A
Wet-lab scientist with a passion for bridging the gap between biology and computer science.

About

I'm a postdoctoral fellow in the National Library of Medicine (NLM) Biomedical Informatics and Data Science Training Program through the Gulf Coast Consortia. My efforts are focused on defining the relationship between the brain and periphery using culture-independent microbiome workflows. My PhD was comprised of environmental microbiome characterization, which I am still very passionate about. I've worked with many different nucleic acid sequencing technologies like Sanger, Illumina, and ONT Nanopore MinION. I am passionate about applying third generation sequencing and novel bioinformatic workflows to determine how microbiomes impacts other biological systems and vice versa.
