Laboratory Investigations Department Staff

Kathy Guillermo

As senior vice president of Laboratory Investigations, Kathy Guillermo heads up the organization’s work to end the use of animals in nonrequired experiments. Some of her major victories include pressuring NASA to scrap plans to irradiate monkeys, persuading the U.S. military to end all chemical-casualty training on monkeys, ending the Coast Guard’s shooting and stabbing of goats and pigs in medical trauma training drills, shutting down the construction of a massive monkey-breeding facility in Puerto Rico, and exposing the abuse of animals at a North Carolina product-testing laboratory—Professional Laboratory and Research Services, Inc.—which led to the closure of the facility and the release of hundreds of dogs and cats, who were put up for adoption.

Guillermo’s 1993 book, Monkey Business: The Disturbing Case That Launched the Animal Rights Movement, with a foreword by Oliver Stone, details the cruelty case that launched the then-fledgling PETA into national prominence. The landmark Silver Spring monkeys case also led to the first-ever conviction of an animal experimenter on cruelty-to-animals charges. Guillermo has been with PETA since 1989.

Alka Chandna, Ph.D.

Dr. Alka Chandna is the vice president of laboratory oversight and special cases. She has submitted dozens of complaints, spotlighting violations of U.S. federal animal welfare laws and noncompliance with federal guidelines and policies. In 2010, after she wrote PETA’s complaint against Professional Laboratory and Research Services, the North Carolina–based contract animal testing facility surrendered nearly 200 dogs and more than 50 cats and shut its doors. More recently, she worked on PETA’s successful campaign to end a series of maternal-deprivation experiments on monkeys at the U.S. National Institutes of Health. She has also had original research published in peer-reviewed journals on policies pertaining to problems with oversight of animal experimentation and has presented some of this work at scientific conferences. Before coming to PETA, Dr. Chandna served as a tenured professor of mathematics at Memorial University of Newfoundland. She has a doctorate in computational fluid dynamics.

Maggie Wiśniewska, Ph.D.

Dr. Maggie Wiśniewska is a science policy advisor. She’s responsible for providing research assistance supporting the replacement of animal testing with more efficient, ethical, and modern non-animal alternatives. Long before joining PETA, Maggie worked as a registered veterinary nurse in an emergency practice and later as a community college science educator. More recently, during her M.S. research at Western Kentucky University, she studied the socioreproductive behavior of African savanna elephants in Namibia and South Africa. While in the field, she witnessed the consequences of resource competition between elephants and humans and realized that most mitigation strategies were based on the exclusion of elephants from traditional wilderness zones. This observation motivated her Ph.D. work at the New Jersey Institute of Technology. In her dissertation, Maggie used statistical modeling and simulation techniques in order to characterize spatial and social predictors of movement by groups of African savanna elephants in human-dominated areas. She hopes her research will help inform human-wildlife conflict mitigation efforts that prioritize safeguarding wild animals for their own sake.

Jen Draiss

Jen Draiss worked with primates at sanctuaries in Africa, Asia, and the U.S. for over a decade before joining PETA’s Laboratory Investigations Department as a research and campaign coordinator. After working with primates rescued from the illegal wildlife trade and retiring from laboratory experiments, she turned her attention to addressing the root causes of these issues. Jen has an undergraduate degree in primate studies and is currently pursuing an Animal Law Master of Studies in Law degree through Lewis & Clark Law School.
