Research Summary

Dr. Ma’s research interests are in examining methods that evaluate drug-drug interactions. His research has elucidated that several methods estimating in vivo, real-time, drug-metabolizing enzyme and transporter activity are inadequate and lack optimal validation. Dr. Ma is also interested in examining pain medication pharmacokinetic and pharmacodynamic variability in opioid-treated, cancer patients. 

Dr. Ma's clinical practice is in pain and palliative care in an outpatient, multidisciplinary clinic at the Moores Cancer Center. Under a collaborative practice protocol, Dr. Ma sees patients and is able to start, stop, or modify therapy to treat symptoms and sides effects of a disease and its treatment
