    Research interests

    Fluoroquinolone-induced tendopathy

    "These are exciting times to be a student of biology. Biotechnology and molecular biology techniques are transforming medicine, therapies for cancer, diagnostics for genetic and infectious diseases, and practically every field of biology from agriculture to zoology. My interest is to train our students, intellectually and with practical skills, to take part in these burgeoning fields of employment and advanced study."
