Dr. Krolak earned his Bachelor of Science degree in Biology from Virginia Commonwealth University in 1975. He then earned his Masters of Science degree in Physiology also from Virginia Commonwealth University in 1977. He then earned a doctorate degree from Oklahoma State University in Insect Biochemistry. Subsequently to earning his doctoral degree, he was awarded a 4 year NIH Postdoctoral Research Fellowship to conduct research in biochemistry and cell biology at the University of Texas Medical School /Health Science Center in Houston, Texas. His research focused on Muscular Dystrophy and Cyclic Nucleotides.

Upon completing his Research Fellowship, Dr. Krolak was commissioned as a Captain (BSC – Biomedical Science Corps) in the United States Air Force. His first duty assignment was as a biochemist at the Armed Forces Radiobiology Research Institute in Bethesda, MD, where he conducted research in the area of radiation biology. His next Air Force assignment to him to Malcolm Grow Medical Center at Andrews AFB, MD for a year to serve as a Medical Technology intern.

After his training in Medical Technology, Dr. Krolak was assigned to the Air Force’s Epidemiology Research Laboratory at Brooks Air Force Base in San Antonio, Texas. Here he served concomitantly as the Chief of Clinical Chemistry and the Chief of Forensic Toxicology. This laboratory served as the Air Force’s Reference Laboratory for patient specimens coming from bases all over the world. He spent 3 years at Brooks AFB before resigning his commission in order to take a Supervisory Health Scientist position at the Centers for Disease Control and Prevention (CDC). His research at the CDC involved conducting research of various aspects of clinical laboratory testing in the United States based on the Congressional legislation found in the Clinical Laboratory Improvement Amendments of 1988. He has since retired from the CDC and Prevention and has spent more time with his wife, teaching online courses, enjoying his grandchildren (Patrick and Hayleigh) and his two Australian labradoodles, Teddy and Ellie.

He is currently a biochemistry instructor at Lotus, teaching the fundamental concept of biochemistry.
