Andrews is an internationally recognized expert on biotechnologies. Her path-breaking litigation about reproductive and genetic technologies and the disposition of frozen embryos caused the National Law Journal to list her as one of the "100 Most Influential Lawyers in America". She was listed as a "Newsmaker of the Year", in the American Bar Association Journal's January 2008 issue. The ABA Journal described Andrews as "a lawyer with a literary bent who has the scientific chops to rival any CSI investigator" and "a genetics expert of international renown, whose influence in the legal ethics surrounding genetics doesn’t stop at the border." Andrews has also been involved in setting policies for genetic technologies. She has been an adviser on genetic and reproductive technology to the United States Congress, the World Health Organization, the National Institutes of Health, the Centers for Disease Control, the United States Department of Health and Human Services, the Institute of Medicine of the National Academy of Sciences, and several foreign nations including the Emirate of Dubai and the French National Assembly. She served as chair of the federal Working Group on the Ethical, Legal, and Social Implications of the Human Genome Project. She also served as a consultant to the science ministers of twelve countries on the issues of embryostem cells, gene patents, and DNA banking. She has advised artists who want to use genetic engineering to become creators with a capital "C" and invent new living species. She is a contributor to a blog, dealing with topics of genetics and reproductive technologies. Andrews is the author of fourteen books and more than one hundred scholarly articles, monographs, and book chapters on subjects including informed consent, medical genetics, and health policy. She coauthored the law school casebook Genetics: Ethics, Law and Policy . In June 2002, she was awarded the Health Law Teachers Award, given by the Health Law Teachers section of the American Society of Law, Medicine and Ethics. In March 2005, she was named an Honorary Fellow of the American College of Legal Medicine. In her nonfiction work The Clone Age, published in 2000, Andrews offers a highly critical account of the motives and methods of a new breed of biological scientists. She expresses concerns about the role of venture capital in medical research and what she sees as technology racing ahead of legal and ethical ground rules. Her book co-authored with sociologist Dorothy Nelkin, Body Bazaar: The Market for Human Tissue in the Biotechnology Age discusses the psychological, social and financial impacts of the commercialization of human tissue. Future Perfect: Confronting Decisions About Genetics outlines the policy models that Andrews recommends for consideration as we enter an age of increasing knowledge of the human genome. Her book I Know Who You Are and I Saw What You Did: Social Networks and the Death of Privacy was released in January 2012. In the book, she explains how individuals' rights are being violated and she proposes a Constitution for social networks and the Web. Andrews is the author of three mystery novels featuring a female geneticist and military lawyer. The Silent Assassin, the second novel in the Dr. Alexandra Blake series, revolves around enemy skulls brought back from the Vietnam War by American soldiers and now stored in a drawer at the National Museum of Health and Medicine in Washington, D.C. This story line was based on six actual existing Vietnamese trophy skulls that are, in fact, stored in a drawer in Washington. On June 22, 2007, Andrews published an Op-Ed in the New York Times in response to the White House visit of Vietnamese President Nguyen Minh Triet. She urged President Bush to return the "trophy skulls." In September 2008, Andrews released the third installment of her mystery series, Immunity. The book involves a geneticist and DEA agent who works feverishly to stop an epidemic in the Southwest United States. A frequent guest on Nightline, 60 Minutes, CBS Morning News, Oprah, and various other programs, Andrews is often interviewed about bioethics. A documentary, "Frozen Angels," which describes her work, premiered at the 2005 Sundance Film Festival.
