Description of Clinical Expertise

I am interested in the evaluation and management of patients with multiple myeloma, AL amyloidosis, and Waldenstrom's macroglobulinemia. I have a particular interest in the evaluation and management of myeloma precursor states, monoclonal gammopathy of undetermined significance (MGUS) and smoldering multiple myeloma (SMM). In addition, I am interested in the other paraprotein-associated diseases such as monoclonal gammopathy of renal significance (MGRS), paraprotein associated neuropathy, cryoglobulinemia, POEMS syndrome and others.

Description of Research Expertise

I am a hematologist-oncologist with a specific research and clinical interest in plasma cell disorders and related dysproteinemias: multiple myeloma, immunoglobulin light chain (AL) amyloidosis, and Waldenstrom’s macroglobulinemia.

I also lead the multi-disciplinary Penn Amyloidosis Program. This is a cross-disciplinary program involving clinicians with expertise in amyloidosis from cardiology, nephrology, pathology and other disciplines.

I am involved in clinical, translational and epidemiologic research throughout the spectrum of plasma cell disorders. My primary research focus is on the myeloma precursor states: monoclonal gammopathy of undetermined significance (MGUS) and smoldering multiple myeloma (SMM). I have previously established that both multiple myeloma (Weiss Blood 2009) and AL amyloidosis (Weiss J Clin Oncol 2014) have precursor states that are detectable for many years prior to diagnosis. I have also validated biomarkers for ultra-high risk SMM (Waxman Leukemia 2014) that have contributed to changing the diagnostic criteria for multiple myeloma requiring treatment (Rajkumar Lancet Oncol 2014).

I am currently performing trials to develop and test novel biomarkers for progression in the myeloma precursor states (MGUS and SMM). I am also participating in trials of early intervention in high risk SMM.

I am also conducting trials of novel agents for AL amyloidosis and relapsed and refractory multiple myeloma.
