Dr. Koti is a Veterinarian with Ph.D. in Molecular Immunology. Research in the Koti laboratory located at the Queen’s Cancer Research Institute (QCRI), focusses on investigating the interactions between host immune physiology and cancer cell intrinsic features that in combination dictate response to immunomodulatory treatments. Using patient derived specimens and immunocompetent mouse models, the primary objectives of our research program are to: 1) develop non-invasive immune monitoring approaches for application as prognostic and predictive indicators for personalized treatments and 2) study the influence of sex and age on anti-tumour immunity and treatment outcomes in bladder cancer.
