Special Interests

Research Interests

Development of diagnostic methods to evaluate complement deficiencies, define genetic defects and study complement activation processes in vitro and in vivo. My laboratory specializes in clinical and diagnostic testing in the area of complement. We receive specimens from patients from all across the U.S., Canada and other countries, as well as participating in clinical and preclinical trials where complement activation is a potential contributor to the pathology of inflammation.

Patient Ratings

The Patient Rating score is an average of all responses to care provider related questions on our independent rating system, the Press Ganey Patient Satisfaction Survey. This survey is about the patient care experience and does not address crucial characteristics like medical decision-making, prescribing the best therapy, and patient outcomes.

Responses are measured on a scale of 1 to 5, with 5 being the best score. Learn more about our patient satisfaction survey.


Comments are collected in our Press Ganey Patient Satisfaction Surveys. Patients are de-identified to protect confidentiality and patient privacy. Learn more about our patient satisfaction survey.
