Charles Strom


Dr. Charles (Buck) Strom has been advancing genetic testing for more than 3 decades. After graduating from University of Chicago with a Ph.D. in Biology and an M.D., Dr. Strom completed an internship and residency in Pediatrics at the University of California, San Diego and a fellowship in Genetics under the legendary Biochemical Geneticist William Nyhan.

Following completion of his fellowship, Dr. Strom became a faculty member at University of Chicago in the Department of Pediatrics and the Committee on Genetics. In addition to clinical service and teaching, he was awarded multiple research grants to pursue his interest in the genetics of growth disorders. He also taught the Medical School Genetics course.

After leaving the University of Chicago, Dr. Strom moved to Illinois Masonic Medical Center and the Reproductive Genetics Institute where he was the clinical director of Pediatric, Reproductive, and Pediatric Genetics and also the Director of the Genetics Laboratory for RGI. In this capacity he and his partner, Yury Verlinsky, pioneered the field of Preimplantation Genetics and published the first description of a successful preimplantation genetic analysis for a Mendelian Disorder (Cystic Fibrosis). Dr. Strom’s laboratory performed the DNA analysis for the Nash family, the first case of preimplantation genetic diagnosis simultaneously for a genetic disease (Fanconi Anemia) and HLA so that an embryo could be selected to be both free of disease and an HLA match. This enabled the umbilical chord blood to be used for a life-saving bone marrow transplant for Molly, a five year old suffering from Fanconi Anemia.

Also, while at Illinois Masonic Medical center, Dr. Strom pioneered the use of DNA testing for forensic and paternity applications.

Dr. Strom departed Illinois to become the Medical Director for the Genetic Testing at Quest Diagnostics Nichols Institute. Under his 16 year tenure, the Genetic Testing Center greatly expanded its test menu and pioneered in developing techniques to perform high through-put genetic testing in an accurate and cost-efficient manner.

After leaving Quest Diagnostics, Dr. Strom discovered the Amperial(tm) technology and has been working closely with its inventor, Dr. David Wong to advance this exciting disruptive technology. Seeing the potential of Amperial(tm) to save lives, Dr. Strom Co-Founded Liquid Diagnostics with 3 long-time friends and colleagues for the sole purpose of advancing this technology.
