Alex Crits-Christoph

I am currently a graduate student in Microbiology in the Banfield Lab at University of Calfornia, Berkeley.
Affiliations: Plant and Microbial Biology, Innovative Genomics Institute

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.

JHU Business Plan Competition - 1st place in General Business category (2014- $6,000).

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.
