Welcome to Eye on DNA. I’m Hsien-Hsien Lei (pron. shen-shen lay) and I’m a PhD-trained epidemiologist and biotech consultant. I graduated from Stanford University with a BA in Human Biology, area of concentration in disease prevention, and received my PhD from the Johns Hopkins University Bloomberg School of Public Health in Epidemiology, Division of Genetic Epidemiology.

I have been blogging about science and health since 2005 and was the founding editor of the b5media Science and Health Channel as well as founding author of GeneticsAndHealth.com, AHeartyLife.com, and PlayLibrary.com. For a time, I was also Community Director of wurk.net and wrote healthcare.wurk.net. I formerly worked for DNA Direct as a Genetics Information Specialist.

I’m passionate about social media and the potential it has to empower people to take charge of their personal health. The Internet and genome technology combined are going to change our lives in ways we can’t even begin to imagine. Medicine in the genome era will touch all of our lives and I’m here to document its progress.

DNA is our past, present, and future. We need to seize it, examine it, and know its power to make it work for us. How will it change your life?

if my husband is blind and i am a normal woman so what is our child going to be?

Comment by rita mulvaney

Hi my niece works in one of the laboratories at Liverpool University. Recently I asked her if she could recommend a company who checks DNA and could tell where our distant ancestors originated from. She sent me your website.

I would be grateful if you could let me know what is involved and the cost, Sincerely Rita (Mrs R Mulvaney)

Comment by Hsien
