Dale Wallis - VP

Job Titles:
  • Member of the Leadership Team
  • Vice President
If you consume dairy products in the United States, chances are very good that your food has been made safer through work done by Dale Wallis. Dale developed the first commercially licensed coliform mastitis vaccine in 1989, and ever since has been a global leader in mastitis vaccines and so much more. She is a key innovator of vaccine products at Hygieia. Following undergraduate education at San Francisco State University and the University of California, Berkeley, Dale received graduate training first in animal nutrition at the University of California, Davis and then in veterinary pathobiology at the University of Minnesota where she studied the biology of Campylobacter bacteria - a significant animal and human pathogen. At the UC Davis School of Veterinary Medicine, she was the first student to develop and pursue a specialty in poultry medicine. She was awarded the degree of Doctor of Veterinary Medicine in 1988. Dale was a longtime student of and collaborator with epidemiologist George B. E. West. After graduation Dale worked in the veterinary vaccine industry where she focused initially on developing and optimizing poultry vaccines against bacterial diseases. She then learned of a technology known as "J5", proposed for use as, among other things, a vaccine against coliform mastitis in dairy cows. Dale was the first person to successfully develop the J5 technology into a commercial vaccine. Today, J5 vaccine products that Dale has developed are widely used throughout the US as an aid in the production of safe, high quality milk products. Throughout her career, Dale has been at the forefront of the industry, introducing novel technologies and developing first-in-the-world vaccines such as those against Staphylococcus and Streptococcus mastitis agents; a second generation J5, the first licensed vaccine against multiple strains of Campylobacter bacteria that cause sheep abortions, a vaccine against bovine footwarts, novel vaccines and chemotherapies for use against cancers, and the world's first commercial vaccine against a venom. Dale is an epidemiologist with a gift for understanding disease processes in a way that few other people are able, and is strongly driven by her desire to help others.

Jim Wallis - Founder, President

Job Titles:
  • Admin
  • Founder
  • Member of the Leadership Team
  • President
  • Industry Leader
Jim is a biotechnology industry leader with a forty-year track record of disease research, invention, and delivery of novel drug and vaccine products for animals and people in need. His passion for bringing new solutions to challenging diseases has driven him to create a rapidly growing laboratory group which deftly combines scientific insight with artistic creativity for remarkable results. Jim initially trained in engineering and business with an emphasis on leadership and management techniques. His scientific work started in 1980 with one of the first clinical demonstrations of lysine as an effective antiviral compound and continued with investigation of antiviral chemotherapies with Richard Shope Jr. at the University of Minnesota. While at Minnesota, Jim extended the scope of his research to include cancers in collaboration with Robert McKinnell, and then later at the University of California at Davis with Dieter Grüenwedel. At Davis, Jim pursued graduate training in analytical chemistry, microbiology, and toxicology in support of work on transition metal biochemistry, particularly organomercurials. He developed several novel analytical techniques during this time. Concurrently, Jim formed Hygieia Biological Laboratories to pursue commercial applications of his work. Shortly after establishing Hygieia, Jim was joined by Dale Wallis, with whom he collaborated on Hygieia's second-generation J-5 vaccine development, dramatically improving the effectiveness and safety of this widely used dairy mastitis product. Since that time, Jim has assembled an increasingly sophisticated and growing team that has produced numerous vaccine and pharmaceutical innovations. Notably, these include discovery of a candidate causative agent for papillomatous digital dermatitis - the most economically devastating dairy cattle disease - and the world's first vaccine for that condition, a novel approach to cancer vaccine development, and the world's first commercial vaccine against a venom. Jim takes pleasure in tackling disease problems of all kinds and is engaged in the development of solutions for some of the world's most significant disease problems. He also takes time to look at special needs that are often ignored by the industry: Hygieia regularly develops vaccines for zoological collections including products for diverse species - several endangered - from primates to reptiles to a pigmy hippopotamus. In his spare time Jim enjoys sailing and flying sailplanes.
