My clinical focus is in multiple myeloma and plasma cell dyscrasias (including monoclonal gammopathy of unknown significance, AL amyloidosis, and Waldenstrom's macroglobulinemia) at Massachusetts General Hospital Cancer Center, where I am the Clinical Director of the Center for Multiple Myeloma. I am actively involved in clinical trials and also serve as the principal investigator on investigator-initiated trials. My clinical practice also includes Mass. General/North Shore Cancer Center in Danvers, MA, with a similar focus on plasma cell disorders.
