Dr. Soldin earned his honors degree in Chemistry at the University of Witwatersrand in South Africa where he subsequently received his Master’s degree in Organic Chemistry, and also his PhD in Biochemistry. He enrolled and obtained his boards in Clinical Chemistry at the University of Toronto and then accepted a tenured professor position at the University of Toronto in Clinical Biochemistry and Pharmacology. During his work in Toronto, Dr. Soldin developed new procedures, based on the pressure-harnessing technology known as high-performance liquid chromatography (HPLC), to effectively and sensitively tease out, one by one, disease markers and drugs. Over the years, first in Toronto and later at Children's National Medical Center and George Washington School of Medicine in Washington, D.C., he used this approach to advise physicians on the treatment of patients with a host of diseases—epilepsy, AIDS, heart disease, and cancers such as neuroblastoma or pheochromocytoma.
