My name is Charles Vrooman and I have a B.S. degree in Microbiology and an A.S. degree in Computer Systems. I have been licensed by the State of California as a Clinical Laboratory Scientist. I have also been registered as a Medical Technologist with the American Society of Clinical Pathology for over 25 years.
I have been recognized for a number of scientific papers published in professional journals in my line of work. I have not only won an award, but have also received good reviews for my first published thriller novel – “Green Power”. “The True Virus”, is my second biotech thriller novel. My most recently released thriller, is "Botox: Thriller".

Computer Made from DNA and Enzymes
Stefan Lovgren
for National Geographic News
February 24, 2003
Israeli scientists have devised a computer that can perform 330 trillion operations per second, more than 100,000 times the speed of the fastest PC. The secret: It runs on DNA.
A year ago, researchers from the Weizmann Institute of Science in Rehovot, Israel, unveiled a programmable molecular computing machine composed of enzymes and DNA molecules instead of silicon microchips. Now the team has gone one step further. In the new device, the single DNA molecule that provides the computer with the input data also provides all the necessary fuel.(less)
