Meet the organisms

Our project requires that we have a large quantity of each of our organisms: dermatophytes and C. elegans.

Trichophyton equinum

Dermatophytes are molds, and when growing as molds they are in multicellular filaments called hyphae. This results in a fuzzy appearance as shown on this plate, or perhaps you have also seen it on mold growing on bread that’s been around for a while. I prefer to work with dermatophyte conidia, the resting bodies they produce that are only one cell. Having single cells means we can be more quantitative (we know exactly how many conidia we add to an experiment).

Dermatophytes growing in their happy home.

To grow conidia, we plate dermatophytes on rather large plates of specialized media. In the image, they are in the incubator, next to normal plates. They will grow for about 2 weeks, then we will harvest the conidia, count them, and confirm their quality (they should be able to grow and they should be the only organism present).

The other organism we work with, C. elegans, actually eat bacteria instead of a growth medium. Last week we made small plates of medium and spotted E. coli onto the plates. We let the E. coli grow a little, then added the C. elegans. Our worms are greatly enjoying their bacterial snack and we have had plenty for our pilot experiments. As you can see from the picture, we made quite a few plates!

A “few” plates. All of them have E. coli already seeded. These will last a while!

A single plate (pen is for size). The spot in the middle is E. coli, which the nematodes will eat.


Research week 1: getting started!

Summer research has officially started! This week was spent getting things set up. We unpacked lab supplies and started working with cultures of our organisms – both the dermatophtyes and C. elegans, our worms. We also learned to use a giant pressure cooker called an autoclave and then used it to sterilize supplies and media. And perhaps most importantly, my students are getting a crash course on how to learn a new field. An important aspect of starting any new project is becoming up-to-date on what’s going on, so we’re leaving plenty of time for literature searches, reading papers, and discussions.

Crowdfunding: It’s not a grant … or is it?

University research is almost exclusively funded on a “grants” model. In this model, the principle investigator (PI) sends a proposal to somewhere like the National Institutes of Health or the National Science Foundation. These large funding bodies review proposals a few times a year using a peer-review process, and a small (very small!) percentage of the proposals will be granted funding. The funding body sends the money directly to the University, which takes a cut to cover “indirect” costs like facility and equipment maintenance, library access, and other things that are necessary for research but not attributable to any one specific research project. The University then puts the remainder of the money into a fund that the PI can draw from to pay personnel and buy supplies. The funding body wants to know that the research dollars are being used appropriately. Having a specific fund for each project allows the University and the PI to keep track of how the money is spent and, presumably, show that it was spent well.

In contrast, the “Athlete’s Foot in Worms?” project, which officially started research this week, is a crowdfunded project. Crowdfunding currently lacks the accountability of the traditional grants system. The PI posts a proposal on-line using a crowdfunding platform that takes care of accepting money from funders and paying the PI  (the SciFund project I participated in used RocketHub). And then … nothing happens. When my research was funded, RocketHub took its cut, sent me a check, and said “congratulations”. They will not be checking up on me to make sure that I sent my funders their thank-you gifts. They will not be asking for  a progress report. If I spend the money on a vacation instead of lab supplies, they wouldn’t know and probably couldn’t do much about it even if they did.

What keeps me firmly in the Pacific Northwest, rather than Bermuda, isn’t RocketHub. Rather, it’s the contract I’ve made with the people who contributed through the RocketHub site: Take this money; make this project happen; honor your obligations with your thank-you gifts and by keeping us updated as the research progresses. If you do, we might fund another of your projects in the future. We might tell our friends and family that you’re worth supporting. If you don’t, you are losing some serious street cred. Some of us know you. Some of us are related to you. Don’t let us down.

This internal monologue, while extremely effective for me at least, does not fit into the University funding system. So, here’s what happened to the crowdfunding money: Rockethub sent me a check. I gave the money to the University. The University very kindly did NOT take a cut (no indirect costs were removed for the “Athlete’s Foot in Worms?” project), and they set up a fund for me to use the money. It’s a little more complicated than paying for everything myself, especially when it comes to transportation costs. However, it means that my paid undergraduate and my two volunteers are covered for liabilities. It also means that I am setting up crowdfunding at this institution as a funding mechanism that will have accountability. I think that’s probably a good thing.
