Alex Crits-Christoph

I am currently a graduate student in Microbiology at University of Calfornia, Berkeley.

Computational analysis of microbial communities; evolution and ecology of microbes and viruses; CRISPR genome editing; bioinformatics software and web development; statistics and machine learning applied to genomics.
My past
BA in Biophysics from Johns Hopkins (2016)
2015-2016 - data analysis @ Second Genome,
2016 summer - genome informatics @ Caribou Biosciences,
2012-2016 - microbial genomics @ DiRuggiero lab at JHU,
2014 - Google Summer of Code.

In the past I have collaborated on individual projects with Marc Halushka, Gary Bader and Mohammed Helmy, and Rachel Karchin. My email and Github are at the top of this page.

Aezon - A team of Johns Hopkins students selected as one of 10 finalists in the $10 million Qualcomm Tricorder X-Prize, a competition to built a medical system capable of diagnosing a user of 15 diseases and conditions. I was in charge of development and operations of the servers which store and analyze patient data.
