As a Navy veteran who worked on a nuclear submarine, Douglas White is no stranger to living in isolation and using the tools at his disposal to help solve complex problems. When the coronavirus outbreak occurred and people around the world suddenly found themselves quarantining at home, White was well equipped to lend his support to help find a solution to the problem. 

Thanks to his background and his role as manager of research computing at the Ocean Information Center (OCEANIC) at the 91原创 Hugh R. Sharp campus in Lewes, Delaware, White was able to act quickly when he heard about initiative, which unites scientists and community volunteers with computing power to understand how viral proteins work and how therapeutics can be designed to stop them.

Shortly after University staff began working remotely, White set up multiple computers at his home in Sussex County to join the Folding at Home effort to run simulations of COVID-19 protein movements and binding receptors to advance vaccine development.

Protein folding

Viral proteins are made up of a linear chain of chemicals called amino acids that spontaneously fold into compact, functional structures. How a protein鈥檚 components are arranged and move determines how that protein will function. Viruses use their proteins to suppress humans鈥� immune systems and reproduce themselves.

Folding at Home uses the power of personal computers to run simulations to understand a protein鈥檚 moving parts. Being able to see all of the moving parts of a protein allows researchers to identify sites within certain proteins that might be targets for drugs or other treatments.

The hope is that by using these computers throughout the world to simulate moving protein parts, a treatable site on a COVID-19 protein will reveal itself. 

鈥淲hat they鈥檙e looking for is something that鈥檚 going to be essentially a key that鈥檚 going to attach to the outside of the COVID virus to muck up the works and keep it from being able to attach to cells,鈥� said White.

Naval instincts

When the COVID-19 virus hit, White said that his old naval instincts kicked right into gear. 

鈥淯sually, in the Navy, we鈥檙e isolated and have to make do with what we鈥檝e got. Right now, I鈥檝e got some old computers and graphics cards at the house, and I wanted to spin those up and try to contribute as much as I can,鈥� said White. 

With a few other IT professionals at 91原创 who are also using their own personal equipment, White formed . The team has been ranked in the top 1% of more than 250,000 in recent weeks. White is folding under the name OCEANIC and has been personally ranked in the 0.5% of more than 2.6 million individuals who are folding at home.

Having run OCEANIC for several years, White has a background in prototyping and setting up information systems for oceanographic research projects. For this project, he saw they needed fast systems to help with the folding. He is using a few advanced graphics cards and augmented and virtual reality gear alongside old work stations that he鈥檚 had over the years or cobbled together from parts that have been thrown away.

White said that individual users install Folding at Home onto their personal computers and set it up to run however it suits their personal preference. They can have it work at light, medium or full speeds and can have it work in the background while they use their computer or have it run when the computer is idle. Work tasks are assigned by Folding at Home depending on a user鈥檚 system.

鈥淚f you鈥檝e just got a central processing unit (CPU), they鈥檒l give you a lighter load that you should be able to figure out in a couple of days. If you鈥檝e got a faster graphics processing unit (GPU), then they鈥檒l load you up and give you some work that would ordinarily take weeks,鈥� said White. 鈥淲ith some of these fast graphics processors, just off the shelves, and with gaming processors, you can do orders of magnitude faster processing. You can help them with the workloads where they鈥檙e trying to work with bigger proteins.鈥�

White is currently looking for resources to help get more computers up and running and said that he could use more RTX 2080 Super Graphics cards, which could be used after the project by 91原创 researchers.

Anyone interested in Folding at Home is welcome to join the 91原创 team, but White said that he just wants people to join the Folding at Home project in any way they can in order to get the job done.

鈥淭he main thing is, if I can get more resources, I can spin more up. I can do stuff up in the cloud and set up infrastructure in the cloud, which would be better for me because then my light bill will be a whole lot less. I definitely don鈥檛 want to see my next light bill,鈥� said White. 鈥淏ut I鈥檓 ex-military and an ex-nuclear reactor operator and I feel like everything I鈥檝e been doing since I鈥檝e got out of the service has been setting me up for this. It鈥檚 just problems that need to be solved, and I like the engineering challenges.

R/V Hugh R. Sharp

鲍顿鈥檚 College of Earth, Ocean and Environment owns and operates a fleet of research vessels that serve not only University faculty, students and scientists, but also researchers from universities, government agencies and private industry across the country. Those vessels are docked at the Hugh R. Sharp campus in Lewes, Delaware.

The R/V Hugh R. Sharp is a 146-foot, state-of-the-art coastal research vessel that operates as a member of the University-National Oceanographic Laboratory System (UNOLS). The R/V Sharp serves marine scientists as a state-of-the-art platform for exploring and sampling the coastal ocean.

The R/V Hugh R. Sharp is a general-purpose vessel. Thanks to its modular design, it is capable of supporting a wide range of marine disciplines including chemical, geological, physical, and biological sciences, as well as acoustics, fisheries, and marine mammal research. The vessel is a regional asset, serving researchers from many institutions throughout the Mid-Atlantic.
