Special Interests

Research Interests

In recent years, epigenetic mechanisms, such as histone modification and DNA methylation, have been identified which, translate environmental signals into gene regulation. These molecular epigenetic processes, translate the myriad environmental signals encountered each day, into definitive regulation of our genome, and by extension, who we are at a basic biological level. Dr. O’Connor’s work focuses on understanding at a molecular and organismal level, how epigenetic mechanisms regulate the decision processes governing immune cell activity in the context of disease. The immune system is comprised of multiple types of autonomous cells that must work together to influence the outcome of disease. Currently, Dr. O’Connor’s lab examines the cross talk between environmental stimuli (such as diet or inflammation), the immune system, and disease (such as Asthma).

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.
