His past appointments include: Senior Scientist at Boyce Thompson Institute; Adjunct Lecturer at NY Institute of Technology; Senior Scientist at ThermoElectron Corp; and Faculty Fellow and Associate Professor at Northeastern Univer-

sity. Currently, Prof. Krull is Professor Emeritus at Northeastern University. He has published more than 100 papers, and served as an editorial reviewer for many journals. Prof. Krull's research interests are in several areas of analytical biochemistry/biotechnology, especially methods for the analysis and detection of biopolymers and largely emphasize the use of separations methods including HPLC, HPCE, mass spectrometry, and capillary electrochromatography. He has developed, validated, and applied such separation methods for numerous proteins, antibodies, and peptides, of natural and/or recombinant derivation, especially those of commercial interest and medicinal applications.
