Can a professor’s invention turn the battle against antibiotic-resistant bacteria?
As a bioscience researcher at the University of Kansas, Joanna Slusky tackles one of public health’s most pressing problems: how to defeat drug-resistant bacteria and restore the healing power of antibiotics.
Slusky was awarded one of five Moore Inventor Fellowships, a three-year grant worth more than 800,000. In October, she was named the recipient of a $2.3 million New Innovator Award from the National Institutes of Health (NIH).

Joanna Slusky, a KU assistant professor of computational biology and molecular biosciences who won a Moore Inventor Fellowship for her work designing a protein that could help stem antibiotic resistance, was named today as the recipient of a $2.3 million New Innovator Award from the National Institutes of Health (NIH).
Slusky’s work in protein design, the subject of a cover story in the current issue of Kansas Alumni, led to her involvement in the University’s successful 2016 bid to land an $11 million, five-year NIH grant that established the KU Center of Biomedical Research Excellence (COBRE): Chemical Biology of Infectious Disease. Asked to contribute research on antibiotic resistance, Slusky turned to a protein she’d invented—dubbed S1245—and stored in a freezer in her lab. After initial tests proved encouraging, she expanded the research to focus on E. coli bacteria with funding from the $825,000 Moore Fellowship.
The New Innovator Award, part of the NIH’s High-Risk, High-Reward Research program, supports exceptionally creative early career investigators who propose innovative, high-impact projects. Slusky says the grant will allow her to expand her focus from E. coli to other bacterial infections which have similar methods of antibiotic resistance.
“The Moore project is really focused on, ‘Let’s make something,’” Slusky says. “The way that this New Innovator Award is structured, it gives me the ability to really explore the science that’s causing this to happen, so that we can use it potentially for other things as well. The science behind this kind of protein-protein interaction should be useful for other inventions that would be against antibiotic resistance, specifically other inventions that might be useful for other types of bacteria, for other types of antibiotic resistance that we could expand into.”
The increasing resistance of harmful bacteria to antibiotic drugs is a growing problem worldwide. According to the Centers for Disease Control, 2 million people in the United States become infected with antibiotic-resistant bacteria each year, and 23,000 die from these infections. Worldwide, the death toll from drug resistance in illnesses such as bacterial infections, malaria, HIV/AIDS or tuberculosis is 700,000. A 2014 British study projected that by 2050 10 million people will die each year because of increasing resistance to antibiotics and other antimicrobial drugs, surpassing the death rate from cancer.
The scientists behind that study also compiled a list of the 10 most dangerous antibiotic-resistant bacteria, and Slusky has theorized that six of the 10 should be susceptible to a protein like S1245. “So far, with the Moore work, we’ve only been playing with one of the six,” Slusky says. “Now we can say, let’s try to generalize this so that we could see if we can impact six of ten.”
