Professor’s journey shapes student experience

David Altman’s first year teaching was punctuated by two nationally competitive grants to study the protein myosin, a family of motor proteins that are core pieces of cellular machinery.

When you clicked on the link to read this story, myosin was at work. It is the cell’s motor, responsible for muscular contraction among many other cellular functions.

“Myosin’s got this elegant simplicity,” the physics professor says. “I want to understand how the motor works.”

Collaborative research

As part of Willamette’s Science Collaborative Research Program (SCRP), Altman works with Jared Green ’11 and Jesse Sant ’12. The team spent last summer building an optical trap in Collins Science Center, using a laser to examine myosin’s behavior. They will analyze the motor’s range of motion and perform experiments to study its function in retinal cells.

“I’m really excited to use the lab for my senior project,” Green says. “David and I sat down and came up with a really cool idea. We’re going to look at how the molecular motor works in endocytosis within eye cells.” Endocytosis is how cells absorb molecules from outside the cell.

The collaborative experience has already paid off for Green, who won a competitive award from the Biophysical Society to present related work on optical trapping at the society’s annual meeting in Baltimore.

The research Altman and his students are doing now will act as the springboard for future projects, continuing to study myosin not just in its original form but also working to engineer specific behavior. Likewise, Altman would like to see Green’s work become the framework for a model of myosin function within eye cells.

Altman’s journey

Altman’s own intellectual voyage mirrors many students’ college journeys. “I like exploring as many things that I don’t understand as possible,” he says.

“I started working with optical traps as an undergraduate in Chicago, where we studied the dynamics of colloids — the dispersion of small particles in liquids.” His optical trap experience paid off in graduate school at Stanford, when he was asked to be part of a biochemistry team. Ultimately his work led to collaboration with a group in India, beginning Altman’s focus on molecular motors in cellular systems.

Altman’s passion for intellectual exploration has influenced his students. The team visited Stanford to create motor proteins using the university’s specialized equipment, and the trip was transformative. “Just sitting in on some of David’s conversations with his colleagues and seeing the immersion you get in grad school where you’re constantly talking and reading about all of these subjects was really cool,” Green says.

Green’s goal is to become an educator, a goal which was well-served by working with Altman through SCRP. “Having a research background and being able to bring a lab to a department would be an advantage,” he says.

Outside the lab

Even the staunchest researchers need a break from the darkened laboratory space required for such optical trap experiments. Altman often meets with students outside of Collins to discuss the team’s work or occasionally to jam — Altman is a percussionist.

“Willamette has been fun in that you get to form really close relationships with a lot of professors,” Green says. “I first got to know David when we played in a band last year at Wulapalooza. It was called Dr. Altman’s Bird Refinery, and we had a really good time.”

When not in the lab or teaching, you might see Altman downtown at Governor’s Cup coffee shop, Venti’s restaurant or Tangled Purls knitting studio. “Our lab in general has become a big fan of Clockworks Café,” Altman says. “That’s become a regular meeting spot.”

Whether in class, working in a lab or chatting over coffee, Altman appreciates the opportunity to get to know students personally. “The interactions in the small classes at Willamette are so wonderful,” he says. “I definitely ended my first year thinking I’m in the right place.”
