Learn More About Qihao
Qihao is passionate about advancing our understanding of how gut microbiota influence xenobiotic metabolism and its broader implications for human health.
Before joining Pitt Pharmacy as a tenure-track assistant professor, Qihao completed his postdoctoral training with Dr. Jason Crawford at Yale Chemistry, where he uncovered how human gut commensal microbiota influence GPCR drug activity through diverse biotransformations.
Qihao earned his Ph.D. in Medicinal Chemistry from Zhejiang University of Technology under the guidance of Dr. Hong Wang and Dr. Yue-Wei Guo. His research, inspired by marine chemical ecology, focused on discovering bioactive marine natural products (MNPs). As a joint-training graduate student with Dr. Yue-Wei Guo at the Shanghai Institute of Materia Medica, Chinese Academy of Sciences, he characterized over 100 MNPs.
During his Ph.D., Qihao joined Dr. David Rowley’s lab at the University of Rhode Island as a visiting research fellow, where he elucidated small molecule-mediated chemical interactions between marine bacterial pathogens and probiotics. His work revealed the pathogenic mechanisms of these molecules and their potential therapeutic applications.
Following his Ph.D., he joined Princeton University as a postdoctoral research associate in Dr. Mohamed Donia’s lab, developing high-throughput, unbiased methodologies to investigate biochemical transformations of orally administered drugs by the human gut microbiome. He later continued his pursuit of novel antibiotic discovery in Dr. Tim Bugni‘s lab at the University of Wisconsin-Madison, where he integrated multi-omics approaches, medicinal chemistry, and mode-of-action studies to develop new antibiotic drug leads.
Qihao enjoys biking, swimming, and building Legos when he is out of the lab.
Postdoctoral Researchers

Learn More About Yansong
Yansong received his Ph.D. from the Kunming Institute of Botany, Chinese Academy of Sciences, where he focused on the structure and bioactivity of natural Polycyclic Polyprenylated Acylphloroglucinol (PPAP) from Hypericum genus. He subsequently carried out postdoctoral research at the Kunming Institute of Botany, University of South Carolina, and University of Texas at Austin.
Yansong’s research lies at the interface of chemistry, metabolomics, and microbiology. He is particularly interested in exploring how gut microbes produce small-molecule natural products and how these metabolites mediate host–microbe ecological interactions. His work aims to uncover novel bioactive molecules and provide new insights into the chemical basis of host–microbiome communication.

Learn More About Nana
Nana received her Ph.D. from the Kunming Institute of Botany, Chinese Academy of Sciences, where she studied the discovery, structural elucidation, and bioactivity evaluation of plant-derived natural products. Her doctoral research focused on polycyclic polyprenylated acylphloroglucinols (PPAPs) from Hypericum species.
Nana’s current research in the Wu Lab focuses on two areas. One area centers on marine natural product discovery, where she uses metabolomics-, genomics-, and activity-guided approaches to investigate bioactive small molecules produced by marine microbes. Her second area focuses on gut microbial metabolism of drugs and xenobiotics, with an emphasis on defining how gut microbes transform these compounds into new metabolites and how these reactions shape host-microbiome chemical interactions.
