Alumni and Collaborators


Mark Musch, PhD

Professor and former lab leader

Mark was a scientific power house and Chang lab super star for over 25 years. He has recently retired from the University.

Daina Ringus, PhD

Former Postdoctoral Scholar

Daina studied the gut virome and its interaction with the gut microbiota and how they alter bacterial community structure and function. Daina is now a medical student at Northwestern University.

Kyle Dolan, PhD

Former Postdoctoral Scholar

Kyle studied the interactions between gut microbes and host epigenomes, with a primary focus on DNA methylation and hydroxymethylation. Kyle has since moved on to become the Head of Science and Innovation at British Consulate-General in Chicago.

Emma Liechty, DVM

Former Postdoctoral Scholar

Emma studied Bacteriodes in the development of pouchitis. She has sinced moved over to Northwestern University to become a clinical veterinarian.

Ketrija Touw, PhD

Former Postdoctoral Scholar

Ketrija’s research focused on the role of intestinal motility in shaping the gut microbiome, understanding the mechanisms through which the host and microbiome interact, and how these relationships can be applied for future interventions to treat gastrointestinal dysmotility. Ketrija has since moved on to Abbot Molecular as a Senior R&D Biologist in GI Research.

Patty Ojeda

Former Howard Hughes Fellow

Working closely with Dr. Kristina Martinez, Patty worked on a project focused on the interactions of the gut microbiome and the constitutive androstane receptor (CAR), a nuclear receptor which plays a significant role in xenobiotic and lipid metabolism. Using CAR knockout mice, she examined changes in development, lipogenomics, and microbiome in various settings.  Patty has returned to medical school to complete her  studies.

Jinlu Tong MD, PhD

Former Visiting Scholar

Jinlu worked on characterizing the role of HSP 25 in inflammatory bowel disease before heading back to his home institution in China.

Edmond Huang, PhD

Former Graduate Student

Edmond’s research focused on the dietary and pharmacologic regulation of the intestinal microbiome. His projects involved characterizing perturbations in the gut microbiota due to these external stimuli as well as their subsequent repercussions on host inflammation in the context of both metabolic dysfunction and inflammatory bowel disease. Edmond is currently a Postdoctoral Fellow at James Olzmann’s lab at the University of California, Berkeley.

Takumu Hasbe, MD, PhD

Former Visiting Scholar

After his tenure in the lab, Tak has returned to the Division of Gastroenterology and Hematology/Oncology at Asahikawa Medical University in Japan.
