Mark’s research activities at NIST include the measurement of amino acids and proteins in human serum. He has developed new methods for quantification of human cardiac troponin I in serum involving immunoassay development and multiple-reaction monitoring mass spectrometry, and performed absolute quantification measurements of amino acids in plasma. These activities have led to the production or certification of several SRMs. A separate focus is on development of techniques for characterization of proteins and small molecules bound to nanoparticles. Mark has co-authored more than a dozen peer-reviewed publications.
