Research and Clinical Interests

My interests lie in the field of mass spectrometry and how we can utilize this technique to measure analytes in clinical samples. Currently we are running LC-MS/MS assays to measure total testosterone, estradiol, busulfan, voriconazole, posaconazole and isavuconazole for the patients at UCSF Medical Center. We are currently developing other small molecule assays and plan to work on protein assays in the future.
