In a haze of coding, caffeine, circuits, teamwork, snacks, and sleep deprivation, around 120 students from Calvin and other universities worked for 24 hours straight, developing a wide range of software and hardware computing projects. The students were competing in Calvin’s first “hackathon,” a marathon software and hardware development competition held from February 8-9 by the CalvinHacks student organization.


As the sun set on February 9, a team of Calvin students emerged victorious, their project—PlantBit—scoring first place. A combination of a smartphone application, an arduino board, a Google Home, and a moisture sensor, PlantBit allows its user to remotely turn on and off grow lights for their plants, while also providing data on the moisture of the plant’s soil.


“It was inspired by the massive amount of succulents I keep in my room,” said team member Lauren Ebels, a biology and computer science major. “I have a whole bunch of grow lights for them, but couldn’t set them to be on when they’d help the plants the most.”


Over the course of the 24 hours, the team divided and conquered: Junior Shion Fukuzawa programmed the remote control iPhone app, Seniors David Widjaja, Megan Koh, and Toussaint Cruise set up the hardware and control database, and Ebels connected the Google Home to the control database.


“There’s a sense of accomplishment,” said Fukuzawa, a math major and computer science minor. “At the end you have to submit something no matter what, and the fact that you worked as a team for 24 hours and actually made something is pretty satisfying.”


“CalvinHacks was a really fun event, and was unlike anything I had ever done before” said Caleb Schmurr, a Calvin junior electrical engineering student whose team worked on a project using an e-ink screen to display information from a Google Home.


“I liked getting the chance to spend time working in an environment that encouraged and supported creative uses of technology,” Schmurr added. “We were able to use our programming abilities gained from either coursework at Calvin or other experiences to create a really unique project.”


Among a multitude of other creative submissions, Calvin teams also designed a web-based video game, a sign language video detection user interface, and an app for tracking grocery purchases.

Conducting a chemical orchestra

Professor Douglas Vander Griend of the chemistry and biochemistry department plans to conduct a symphony this summer, with the assistance of two student researchers and Calvin’s new supercomputer. Or at least, that’s how he invites those not well-versed in technical chemistry to understand his current work building a chemometric website for the modeling of complex chemical solutions.

 

The website software takes the spectrographic—or light—output of an experiment and tries to match it against a multitude of simulated experiments. When a similar simulated output is found, the software then shows the researcher what chemical interactions may have produced that output.

 

“Imagine that you’re in a concert hall, and you’re listening to instrumentalists play on a stage, but the curtain is drawn so you can’t see anything, and everybody’s playing instruments you’ve never heard before,” Vander Griend said. “So you can hear what they produce, and your job is with your ears to figure out how many instrumentalists are on stage and what type of instruments each one is playing.

 

“We do almost the exact same thing with molecules and light,” he added, “we make them play a song.”

Harmonizing distinct disciplines

Aiding him in conducting this obscure orchestra are student researchers Joyce Chew and Nathanael Kazmierczak. Chew is a junior majoring in math, and minoring in computer science and chemistry, while Kazmierczak is a senior majoring in music and chemistry, and minoring in ministry leadership.

 

Vander Griend points to both students’ backgrounds in multiple disciplines as a strength: “When someone can bring in a mindset and toolbox developed in a different area, they bring fresh insight into new problems.”

 

Both are thrilled with the interdisciplinary nature of the project. “I really like that this [research] integrates math, computer science, and chemistry, because those are my core three interests,” said Chew.

 

Kazmierczak views this kind of research as unique to Calvin: “as a liberal arts institution, Calvin has really open lines of communication between the disciplines;” he added, “there’s a lot of collaboration work going on in the sciences.”

 

In addition to being able to work within multiple fields, both also enjoy working with Vander Griend. Having done research with him for over two years, Kazmierczak identified his attitude as “a hands off one, which really helps you develop as an independent scientist.” Chew agreed; although this is her first time doing chemistry research, she said “he made it really easy for me to jump in, get into the literature, and get caught up with what was happening in his lab.”

Cutting-edge tools

Vander Griend’s ensemble is completed by Calvin’s new supercomputer. Access to the supercomputer, according to Vander Griend, is “expanding out the functionality” of the software, allowing for the automation of model construction, the building of a database for results, and extensive error analysis.

 

Vander Griend identified the error analysis specifically as one of the super computer’s key contributions to the project: “you’re talking hours and hours and hours [of computations]; the supercomputer can bring that down minutes.”

Measuring Plaster Creek’s progress in microbes

E. Coli, a largely harmless but occasionally dangerous bacteria present in animal and human feces, is found throughout the Plaster Creek watershed. The E. Coli strains present in the watershed from animal waste are likely the product of agricultural runoff. However, when it comes to the E. Coli from human waste, according to professor Kelly DuBois, “it’s really not known where that’s coming from.”

 

So, does DuBois, a professor of biology, intend to track down the source? “Based on how often they’re finding [E. Coli]—all over the place—it can’t be one source, so we have a really small chance of pinpointing all the sources and shutting them all down,” said DuBois.

 

Instead, she is working with a group of student researchers to assess if green infrastructure installations could be an environmentally safe solution. In particular, they are looking at the impact of Kreiser pond, a retention basin installed in a residential area of Grand Rapids four or five years ago, “which is essentially a U-shaped little pond,” built to slow rainwater runoff. “We know it slows the flow down, it absolutely works for that,” said DuBois, “but my question was: what is it doing with the microbes in the water?”

A collaborative legacy

While according to DuBois, “it’s been shown in some instances that green infrastructure can be really efficient at removing bacterial contamination,” she hopes to prove that it’s effective in Plaster Creek’s case so that future green infrastructure projects in the watershed can be designed with microbial reduction in mind.

 

The project is in collaboration with the Plaster Creek Stewards, a group of Calvin faculty, staff, and students who have been working over a decade on the restoration of the Plaster Creek watershed. “It’s a fun group to be a  part of,” said DuBois, “because there’s so much collaboration, and everyone comes at it from a little different perspective.”

 

DuBois was inspired to work with Plaster Creek Stewards after doing research through Calvin’s Clean Water Institute last year. “I was really excited to be a part of [the Clean Water Institute], and that has kind of led to [working with Plaster Creek],” she said, “because I developed that skill set last summer with my student, it was like ‘hey, we can apply these [tools] to Plaster Creek too!”

Pursuing proper stewardship

“As biologists, obviously, creation care is something that’s very important to us,” DuBois said, “I honestly love bench science, but it’s nice to have a project [where] it’s easier for students to see the direct connection with taking care of creation.” She added, “we can see, when we measure stuff in that water, that humans have had a negative impact on this little part of creation, and so it’s very practical to say we want to turn that around now.”

 

One of the student researchers, Kate DeHeer, a junior majoring in biology and biochemistry, has observed firsthand the positive community impacts of the Steward’s work: “we’ve only been out to the pond twice, but have met around five neighbors interested in our work.” She added, “they all seem to be fond of Kreiser and were happy to have it in their neighborhood.”

 

According to Tobe Ndika, a junior biology major with a pre-med concentration, “[this research] has made me aware of the need for stewardship towards God’s creation.” He added “I feel called to make the world a better place.”

Finding answers and building network for rare disease community

How can mutations in one supposedly single-function protein result in four unique diseases with symptoms ranging from strangely textured hair to early death?

 

That’s the question that biochemistry professor Rachael Baker and biology professor Amy Wilstermann are seeking to answer through three linked research projects this summer. Working with three student researchers to conduct experiments on the mitochondria of yeast and zebrafish, the professors are examining the effects of mutations in the protein’s gene to determine its other roles within the cell.

 

By discovering how each mutation results in each disease, Baker says they hope to more fully understand the mitochondrial system, leading to both “better treatments for people affected by rare diseases and a better understanding about health and wellness in general that could lead to treatments for things like cancer and other disorders.”

Beyond the lab

Baker and Wilstermann, however, view these direct applications as only one step in the larger process of improving the lives of those with rare diseases.

 

“There’s just a lot of uncertainty [around rare disease]; even when you get a diagnosis, you might not know what the prognosis is,” said Wilstermann. She and Baker aim to help remedy this through two key routes: improving the readability of scholarly work on rare disease and providing a website to collect information for patients and their families.

 

During the summer, Wilstermann says, the students will work toward both goals by reviewing the literature around a specific rare disease and writing a condensed summary for the website, giving them practice in “taking really complicated ideas and mak[ing] them accessible but still completely accurate.” Wilstermann says that the students will most likely start by covering the diseases which were represented at the rare disease symposium (in March 2018) and are present in the local community.

 

The website is broadly intended to function as a network for members of the rare disease community, including patients, families, clinicians, and researchers. “We want it to be a place where we can connect people with resources; we want it to be a place where people can connect with one another,” Wilstermann said. “There’s opportunity to bring people together and help build a supportive community around common experiences, and the common experience of being rare.”

A faith-driven approach

“This project, for me, encapsulates why I came to be a professor at Calvin college,” said Baker. “The way we do science looks different here,” she added. “We eat together each week, we value each other, and we [work] in a body of Christ model where different people have different strengths and interests [which we] bring together to be a functioning whole. We’ve employed various practices that are really rooted in Christian principles, and we’ve used those to shape how we run our research team.

 

“To me,” Baker said, “it’s really exciting that I get to do that and think about it explicitly.”
