Nervous System Engineers
Superpowered by Stem Cells
The Stem Cell Bioprocessing and Regenerative Biomaterials Lab bioengineers neural tissue to study the nervous system. 🧠 Brains, spines, nerves, oh my!
Why Research Matters
Miranda’s Story
When Miranda suffered a spinal cord injury at a very young age, she and her family began learning about treatment options for people with injuries like hers. This led to Miranda getting interested in central nervous system research being done with stem cells. What Miranda learned—along with the positive interactions she had with the health care workers who helped her—sparked her interest in the field of science.
“Science is everywhere around us, and we can come to appreciate that when we have people that dedicate their careers and their lives and their time to finding answers, [it makes] things better for the rest of the world and the people in it.”
Questions to consider
- Miranda’s respect for her physical therapists inspired her to pursue a career in science. What interactions have you had with people in science careers? What did they do and how have they influenced you?
- Miranda’s injury prompted her to learn more about stem cells. What do you already know about stem cells? What do you want to know about how they work or what they can do?
Science Practices

Students Ask Scientists
Ever wonder what scientists do every day, or what kind of equipment they use in their lab? Join middle schoolers from Milwaukee, Wisconsin and researchers from the Stem Cell Bioprocessing and Regenerative Biomaterials Lab to learn more about what research really looks like!
Questions to consider
- Using different mold shapes can encourage stem cells to grow into entirely different types of tissues. Can you think of common items that are made of the same material, but have different functions due to the different molds they were made in?
- When you break down the word bioengineering into its parts, what does that tell you about what the lab does?
“Making really small contributions really leads up to—in the long run—people being able to make great discoveries and great medical advances that are going to help human lives.”

Randy Ashton
Principal Investigator
I am in charge of the scientific, academic, and commercial output of the lab. This means that I hire lab personnel, provide training for students, and help produce all scientific papers, presentations, patents, and grant proposals.

Carlos Marti-Figueroa
Postdoctoral Researcher
I come up with ways to engineer the size and shape of 3D tissues derived from human stem cells, so that they will be similar to the brain. 🧠

Nisha Iyer
Postdoctoral Researcher
I develop ways to direct human stem cells into every type of neuron in the brain and spinal cord… from the neurons that help you move to those that help you feel. 🖐️

Frank Seipel
Graduate Student
I work with stem cells to create models of the developing brain and spinal cord. 🧠
