Angela Cruz-Hernandez
Graduate Student
Phone: 303-724-8216
Angela is investigating the role of mast cells in response to sulfur and nitrogen mustard exposure and the relationship of mast cells to symptoms of Gulf War Illness.  

Ryan Mendoza

Graduate Student
Phone: 303-724-8216
Ryan is investigating novel non-IgE mediated pathways of mast cell activation following nanoparticle exposure.  In addition, Ryan is working to understand how the biocorona formed on engineered nanomaterials impacts immune responses.
