Dr. Cheryl Dyer earned her PhD in reproductive sciences at the School of Medicine, University of California at San Diego. Her postdoctoral training took place in a nationally recognized plasma lipoprotein research group at The Scripps Research Institute, La Jolla, CA.

In 2004, she with Dr. Loretta Mayer founded SenesTech, LLC. They invented and patented the technology for ContraPest, an EPA registered orally active bait that prevents rat reproduction. In 2019, Dr. Dyer and Dr. Mayer left SenesTech, Inc. to pursue their goal of developing new baits to prevent reproduction in wildlife populations that conflict with people. Their goal is to make this new product affordable to non-profit animal refuges and sanctuaries.

Dr. Loretta P. Mayer

Dr. Loretta P. Mayer

Project Director

After 20 years in the business world, Dr Mayer, returned to school and received both Master’s and Ph.D. degrees in Biology from Northern Arizona University. She accepted a post-doctoral appointment with the College of Medicine at the University of Arizona and it was there that she developed a chemical method of inducing peri- and post- menopause in rodents. She is the co-inventor of a patent for the Mouseopause™ model, which is available to research and educational institutions worldwide. Dr. Mayer continues to publish using this model providing cutting edge research in ovarian cancer,
neuroscience and Alzheimer’s, osteoporosis, and heart disease in women.

In 2004, Loretta was invited onto the Navajo Nation to investigate the possibility of using Mouseopause™ to chemically spay feral dogs and cats. This research effort gave rise to development of the first oral contraceptive in rats and founding of SenesTech, Inc. with Dr. Cheryl Dyer. Their work has been used around the world to pursue fertility control in Wildlife. Examples are wallaby, rats and mice in Australia, brush-tail possum in New Zealand, stray dogs in India, rice rats in Indonesia, Philippines and Myanmar, and cats in Florida.

Tom’s next project was to form the framework of the Arizona Heritage Program, the first of its kind in the U.S. This program was also the first to receive general fund revenues for the protection of threatened, endangered critical wildlife habitats and management of non-game species. While he was the Heritage Program Director Tom also received the Arizona Game & Fish Commission Employee of the Year.

He has been working to bring fertility control of invasive wildlife to the main stage of animal population management with Drs. Mayer and Dyer for the past 10 years. No project too small and no challenge too great, Tom is “all in”.
