Happy to share the latest manuscript from our lab, in which we propose that eukaryotes evolved from a genomic chimera of Asgard archaea and giant viruses.

This is a controversial topic, but we believe we have strong evidence to suggest a critical viral role in eukaryogenesis.

Very interesting story about the #nitroplast, a potential new organelle resulting from #symbiosis between nitrogen-fixing bacteria and the #microalgae Braarudosphaera bigelowii based on subcellular imaging and proteomic data.
Possibly a new model to study the evolutionary transition from #endosymbiont to organelle.

Hi #biology hive mind: there is a large unicellular organism with many symbiotic spirochete-like bacteria attached to its outer membrane, acting like its own motility system. What's its name?

#introduction
Hello everyone!
I’m an associate prof at Virginia Tech studying viral diversity. Lately my group has been focusing on giant viruses, but we are also interested in other protist viruses, and the role of viral endogenization in host genome evolution.

Recently we have been examining the strange and complex genes encoded in giant virus genomes!
