Rosana Ferreira
  • Assistant Professor


Rosana holds a B.Sc. (2000) and M.Sc. (2002) in Microbiology from Universidade Federal do Rio de Janeiro (Brazil), as well as a Ph.D. from the University of Iowa (USA, 2007). After obtaining her Ph.D., Rosana did her post-doc studies (2008-2012) at the University of British Columbia (Canada). Rosana was an Associate Professor at Universidade Federal do Rio de Janeiro and joinedKU in January 2023, where she is an Assistant Professor at the Department of Molecular Biosciences. 


Ph.D. in Microbiology, University of Iowa, 2007
M.S. in Microbiology, Universidade Federal do Rio de Janeiro (Brazil), 2002


Rosana's research focuses on understanding how the skin microbiome protects humans and animals against skin infections and how different species interact in the microbiome. Specifically, her research group investigates both antagonistic and beneficial bacterial interactions to better understand how microbiome composition is established in different hosts and how it protects us against infections. Her main research interests are the skin microbiota, new bioactive molecules, virulence factors, single and mixed biofilms, and regulation of gene expression in bacteria.


  • BIOL 507 – Bacterial Infectious Diseases Laboratory (Undergraduate, Spring)
  • BIOL 812 - Mechanisms of Host-Parasite Relationships (Graduate, Spring 2025)

My teaching primarily includes teaching bacterial pathogenesis mechanisms (BIOL507 and BIOL812). In my teaching I use active learning techniques and include research projects and papers to give the students an opportunity to think critically about what they are learning and how they can apply that knowledge to scientific questions. Outside of the classroom, I take pride in mentoring and train an international and inclusive group of scientists, including undergraduate, graduate and postdoctoral trainees, to conduct research in my laboratory.
