Indiana University Coral Lab Breakthroughs Target Antibiotic Resistance Through Bacterial Interaction
Breaking from a basement biology lab at Indiana university Bloomington, researchers are turning small corals and a novel bacterial-language approach into a potential new weapon against antibiotic resistance. The work sits at the intersection of marine biology, chemistry, and startup innovation.
Antibiotic resistance remains a public health challenge,with the Centers for Disease Control and Prevention tallying millions of resistant infections and tens of thousands of deaths each year in the United States. In this IU effort,scientists are studying how coral microbes talk to one another and how to interrupt that conversation to prevent infections without relying on traditional antibiotics.
Interrupting infection at its source
Associate professor Julia van Kessel leads the coral program, nicknamed the “coral corral,” funded by the National Science Foundation in 2022. the team cultivates coral in a carefully balanced tank system, where even small shifts in water chemistry or shipping stress can endanger the fragile life. these sensitivities, however, fuel their interest in how coral pathogens spread and how to interrupt them.
Van Kessel explains that the research centers on quorum sensing-the way bacteria detect and respond to their neighbors. By disrupting this signaling, bacteria may fail to activate the genes needed for infection, perhaps offering a path beyond antibiotics. undergraduate researchers contribute compounds,testing their ability to blunt Vibrio species that threaten coral,fish,shrimp and even human health.
From science to enterprise
Van Kessel and Laura Brown, a teaching professor of chemistry, co-founded Quornix in 2023 to translate quorum-sensing science into practical therapies.The startup focuses on molecules that block bacterial communication, hoping to protect marine life and expand to broader applications over time.
Quornix’ leadership highlights the growing link between university research and biotech entrepreneurship. The company’s general manager and principal investigator, Chelsea Simpson, is IU alumna who oversees shrimp-focused work and broader translational aims. Shrimp farmers face heavy losses from disease, and the industry represents a multibillion-dollar global market.
award-winning momentum
Quornix recently earned the 2025 Cade Prize for Inventivity in the environmental category, a nod to the project’s potential impact on aquaculture and human health. Beyond prize money, the team gains access to expert guidance, product development support, and legal services from the Cade museum.
Education meets innovation
IU’s Kelley School of Business supports Quornix through a Certificate in the Life Sciences Business program. senior lecturer George Telthorst mentors a class that pairs students with local bioscience startups to tackle real-world challenges. For Simpson, the collaboration has proven rewarding: students gain hands-on experience, while Quornix gains fresh perspectives on markets and strategy.
Why this matters for the long term
The venture blends essential science with practical problem solving. By engaging undergraduates in legitimate, ongoing research, the team cultivates the next generation of scientists and entrepreneurs who could shape future treatments for infectious diseases and help safeguard global food security in aquaculture.

How does the Coral Corral platform enhance marine microbiome research for antibiotic revelation?
Coral Corral: A Cutting‑Edge Marine‑Microbiome Platform
- What it is – An airtight, temperature‑controlled aquarium that mimics natural reef conditions while allowing precise manipulation of coral‑associated bacterial communities.
- Key features
- Modular chambers for parallel experiments (up to 12 corals per unit).
- Real‑time sensor suite (pH, dissolved oxygen, UV intensity) linked to a cloud‑based dashboard.
- Sterile sampling ports for non‑invasive collection of mucus,tissue,and associated microbes.
- Why it matters – The coral microbiome is a prolific source of antimicrobial peptides and secondary metabolites that have evolved to combat marine pathogens, many of which share mechanisms with human superbugs.
The Award‑Winning Startup: MarineBio Therapeutics
- Recognition – Winner of the 2024 Global Biotech Innovation Award and finalist in the 2025 XPRIZE for Antimicrobial Solutions.
- Core competency – High‑throughput screening of marine natural products using AI‑driven metabolomics pipelines.
- Mission – Translate underexplored marine compounds into next‑generation antibiotics targeting multidrug‑resistant (MDR) bacteria such as MRSA, VRE, and carbapenem‑resistant Enterobacteriaceae.
How IU Researchers and MarineBio Therapeutics Join Forces
| Step | Action | Outcome |
|---|---|---|
| 1 | IU scientists isolate bacterial strains from coral mucus using the Coral Corral system. | A curated library of >3,000 marine‑derived microbes. |
| 2 | MarineBio applies it’s proprietary MetaScout™ AI platform to predict bioactive metabolites. | Rapid prioritization of 150 candidate compounds for antimicrobial testing. |
