I have 20 years of experience, and specialize in the field of disease diagnosis, prevention and treatment with specific knowledge in the areas of metabolism, protein modification and drug development. I have published on such topics as vitamin as nutritional supplement, novel assays for biological enzymes and novel antibacterial agents as drug candidates. I have testified on SAM-e (S-adenosyl-methionine) as nutritional supplement. All four undergraduate who did research in my laboratory and wanted to attend medical schools are now in top medical schools.
