About Kelle Freel

I'm currently a postdoc working at the Hawai'i Institute of Marine Biology with Dr. Mike Rappé. I'm interested in the biogeography and ecology of microbes, especially of the marine variety. After studying a unique genus of marine bacteria at Scripps Oceanography in grad school, I moved to France, where I worked with a group studying yeast population genomics. In my free time, I like to do outdoorsy stuff, travel, and cook.

The eyes have it!

Eyes are pretty darn complicated, which makes them cool models for studying complex trait evolution.  Maybe the first time I realized how interesting eyes are when I saw this by the oatmeal about the amazing-ness of the mantis shrimp (are they your … Continue reading

What is DAS? A new tool to recover genomes from metagenomes

There are a lot of data out there, and if you haven’t already noticed the ‘omics train has steadily stayed its path through the fruitful (but challenging) world of metagenomics. Metagenomics offers the chance to unravel complex microbial communities without … Continue reading

Found in translation: The evolutionary history of RNA viruses in vertebrates

I have to admit, viruses aren’t normally my thing, but this is pretty darn cool. In a study out by Shi and colleagues this week, researchers identified 214 new viruses that, as the authors so succinctly state, reveal “diverse virus-host … Continue reading

What’s in a name? A review of cryptic species and species concepts

It is a contentious can of worms. Species concepts are both essential to understand and at the same time incredibly difficult to define. Species names allow us to discuss fundamental units of biodiversity in any ecosystem and study genome evolution, … Continue reading

Exploring the genomic diversity of tubeworm endosymbionts

Tubeworms are cool. (To be read only in your best (eleventh) Doctor Who voice). Although, depending on how close they are to a hydrothermal vent, they might be more on the hot side….Regardless, if you’re on the fence about how … Continue reading

Retrieving a million sequences and avoiding primer bias, a new method that might have it all

We have come a long way since the early days when sequencing was a breakthrough method initially used to identify uncultured microbes from the environment. It is now been almost three decades, in fact, since the first microbial 16S rRNA … Continue reading

Diving deep: Exploring microbial communities under the seafloor

As we all sat staring at three large monitors in the front of the room, the remotely operated vehicle (ROV) Jason hung on to a borehole observatory with one hydraulic arm as the other arm plugged our sampling equipment into … Continue reading

0.80994 leagues under the sea

After a month on the water (and a few weeks getting my land legs again), I’m happily settling back in at home. I just returned from an expedition to a site known as North Pond along the western flank of … Continue reading

We have the technology. Is sequencing getting better, smaller, faster?

Okay, I know some version of the phrase “recent developments in rapid and affordable sequencing have made blah blah blah possible…” is something you’ve probably read 10,000 times. However, third-generation sequencing platforms have turned out to be pretty darn astounding. … Continue reading

Non-model organisms are so hot right now

What makes a model organism? Well, as the name suggests, they are widely studied and have been adapted to a vast array of common genetic techniques. A few of the most often utilized organisms, which you are most likely already … Continue reading
