Research Interests

The Pearson Lab for Immunomodulatory Biomaterials is focused on developing strategies for treating dysregulated immune responses such as allergy, inflammation, and cancer through the intersection of two enabling disciplines, nanotechnology and immune engineering.

Current Projects

  1. Polymeric nanoassemblies for precise tuning of immune responses (NIGMS R35GM142752).
  2. Multimodal immunomodulatory strategy to treat inflammation and immunosuppression in sepsis (Shock Society Faculty Research Award).
  3. Immunomodulatory Approaches for Heterotopic Ossification (MIPS and NSF STTR 2136542).
  4. Excipient-free ionizable polyester nanoparticles for mRNA delivery.
  5. Engineering B cell modulating vaccines for T cell cancer immunotherapy.
