Publications and Research Interests:

From 1964 to present: 190 research papers and 35 review articles. Of the research papers, 14 deal with the isolation and characterization of the unusual bacteriophage phi 6 and 121 papers deal with the isolation and characterization of chlorella viruses. The majority of the remaining papers are on the physiology and biochemistry of fungal development. All of my current research efforts are on viruses of eukaryotic algae.
