Leroy Hood

Leroy "Lee" Edward Hood is an American biologist who has served on the faculties at the California Institute of Technology (Caltech) and the University of Washington. Hood has developed ground-breaking scientific instruments which made possible major advances in the biological sciences and the medical sciences. These include the first gas phase protein sequencer (1982), for determining the sequence of amino acids in a given protein; a DNA synthesizer (1983), to synthesize short sections of DNA; a peptide synthesizer (1984), to combine amino acids into longer peptides and short proteins; the first automated DNA sequencer (1986), to identify the order of nucleotides in DNA; ink-jet oligonucleotide technology for synthesizing DNA and nanostring technology for analyzing single molecules of DNA and RNA.
