Ana María was born in Buenos Aires, Argentina on February 27, 1958. She is the daughter of Spanish immigrants who moved to Caracas, Venezuela, where Ana María grew up. In 1979, she graduated from Simón Bolívar University in Caracas, with a bachelor's degree in Biology. From 1980 to 1982 she completed her master's degree in Biology at the Venezuelan Institute for Scientific Research in Caracas. After graduation, she enrolled in the doctorate program in 1983. She received her Ph.D. in Biology and Immunology from the Venezuelan Institute for Scientific Research.


In 1987, Ana María moved to the United States and worked on her first postdoctoral training at the University of Texas, Southwestern Medical Center at Dallas. Her second postdoctoral training was at the University of Texas, Medical Branch in Galveston.

She worked one year as an Assistant Professor at the Department of Biology of the University of Tulsa, Oklahoma. By the year 2000, she had published about twenty articles in science journals about her research.

Besides doing research in the fields of Biology, Microbiology, Immunology, Genetics, Cell Biology and Biochemistry, she taught basic and advanced theoretical and laboratory courses in those areas for graduate and undergraduate students.

In the meantime, she was also a volunteer scientist in the children’s SCIENCE-BY-MAIL program sponsored by the Museum of Science in Boston until the program terminated in 1999. As a volunteer scientist in this program, she received science reports written by Intermediate School students about experiments assigned beforehand. She went over their reports and wrote back to the students with my comments and suggestions.


Her fascination with science slowly developed into the focus of her writing. When Ana María decided to write for children professionally, she enrolled in the Institute of Children’s Literature at West Redding, Connecticut. She graduated from three of their ‘by-mail’ writing courses: Writing for Children and Teenagers (1995), Beyond the Basics: Creating & Selling Short Stories and Articles (1999), and Writing and Selling Children’s Books (2001). Since August 2003 she is part of the faculty at the Institute of Children’s Literature. (


In 1999, Ana María became a full-time children’s science writer and her first published article appeared in YES MAG: Canada's Science Magazine for Kids ("Some Love it Hot!"). By October 2007, she has published about 80 articles in children’s magazines like Highlights for Children, Yes Mag: Canada’s Science Magazine for Kids, KNOW, SuperScience, and Current Health 1.

Four of her articles have been reprinted in SIRS Discoverer databases for schools, one in First-Time Authors, a book anthology published by the Institute of Children’s Literature, and another one by the Minnesota Comprehensive Assessments Field test in 2004. Her articles have also been republished by Educational Testing Services and Pearson’s Educational Services in 2004, CTB/McGraw Hill in 2004 and 2005, Harcourt Assessment and West Educational in 2005 and 2006, and People Publishing Group in 2006. More are coming in 2008.

Her work has also appeared in the adult magazines Petersen’s Hunting, Just Labs, and Equus. Some of her work appears under the pen name of Mariana Relós.

One of her first published articles, “The Kids Who Fought Smallpox” (May 2000), received the Highlights for Children History Feature of the Year Award 2000.


Ana Maria is the author of six books for children: "Fires," published in October 2003 by Lucent Books (for Elementary and Intermediate School children) and a second book also titled "Fires," published in January 2004 by Greenhaven Press (for High School students).

Her third book, "Edward Jenner Conqueror of Smallpox" (Enslow Publishers), was released in January 2006,and is included in the Best Books List 2006 selected by Science Books & Films (American Association for the Advancement of Science, AAAS)(To read a "highly-recommended" review go to "My Works" and click on "Edward Jenner")

Ana Maria's fourth book, "A Day in the Life of the Brain,(Chelsea Publishers) appeared in January 2007." In the summer of 2007, "Get Fit!" and "Bicycles Math in Motion" were publshed by Pearson Learning Group.

She also translated the Atlas of Anatomy from Spanish to English in 1997 for Barron’s Educational Series, which is still in print.

She’s currently working on a 6-book series and one more book, which will be published late 2008.
