Ian Hewson, Department of Microbiology, Cornell University **I was asked recently to put together a non-oceanographer/scientist explanation of sea star wasting and our recent work on boundary layer oxygen diffusion limitation, which is below** Seven years into our investigation of sea star wasting, we have learned much about starfish, their biology, and how they interact… Read More Explanation of Boundary Layer Oxygen Diffusion Limitation Hypothesis for Sea Star Wasting
After many years of concerted investigation, the team and some colleagues now have multiple, convergent lines of evidence to suggest that sea star wasting disease is a sequela of organic matter remineralization (and subsequent hypoxic conditions) in the boundary layer overlying respiratory surfaces. We see this reflected in microbiome trends during wasting (copiotrophs –> anaerobes).… Read More New Preprint on Sea Star Wasting – It’s all about the Boundary Layer
Gideon Mordecai (UBC) and I have recently published a mini-review on marine coronaviruses in the journal Frontiers in Microbiology. While not much is known about the true diversity of coronaviruses in marine ecosystems (because they are hugely under-sampled), we can learn about how they may behave in marine habitats through other enveloped, ssRNA viruses.
It’s been over a year since last I updated the lab websites, but for good reason! It’s been an incredibly busy and productive period in our journey – coming to the end of current projects and starting new avenues of research. First, an update on sea star wasting, which has been a major focus of… Read More A year goes by so quickly!

Summer’s wound up for another year, which means the end of a field season. Sea star wasting is, however, only just ramping up. We’ve sadly learned of wasting in several constantly monitored populations of sea stars which had shown a strong recovery since the 2013-2014…

After a highly successful and productive sabbatical in New Zealand (stay tuned for interesting results), we’re back in action investigating sea star wasting in North America. Reports from collaborators and citizen scientists from the west coast indicate that wasting continues at a low(ish) level in sea star populations this boreal spring at some sites, and… Read More New Experiments in Santa Cruz
Nine years ago I participated in a triathlon on Cayuga Lake. At the time, I was a pretty fast swimmer (not anymore I fear…) and came in 4th overall in the swim leg amongst >500 competitors. During the swim in the lake, aside from trying to swim in a straight line, I incidentally ingested quite… Read More New Publication! – this time on Freshwater RNA Viruses.
Any postdocs want to come and work with me? Here’s a great opportunity for funding from the Simons Foundation: https://www.simonsfoundation.org/grant/simons-postdoctoral-fellowships-in-marine-microbial-ecology/ Broadly, any projects should be focused around microbial ecology – so probably NOT projects related to disease pathobiology. Ideas for viable projects include: Virus-zooplankton interactions; Viral-biofoulant (e.g. barnacles, tunicates, etc) interactions; Microbiology of metazoan diseases;… Read More Postdoc Fellowship!
Four years ago I published a paper that identified the sea star associated densovirus (SSaDV) as the best candidate culprit for sea star wasting disease. Eight months later, my dad passed away from a rare condition called “myelodysplastic syndrome”, which is a heterogeneous group of diseases that manifest with similar symptoms. Often in biology and… Read More New Paper on Sea Star Wasting!
