Meet Our Team

Ronald Landis, Ph.D.

Chairman of the Board

Dr. Ron Landis is Co-founder and CEO of Landis International, Inc. He has over 40 years of experience in the agricultural research and development area and has been actively working with and negotiating with the USDA/EPA since 1969, before the present-day EPA was formed.

With the founding of Landis in 1982, Dr. Landis introduced the concept of contract project management into the agricultural chemical realm. Prior to this, he had twelve years’ experience developing his project management skills in the agricultural chemical industry. He has developed contract ag-chem project management from its beginnings in 1982 to today’s computer-assisted project and program management.
Dr. Landis and Landis International’s approach to working with the U.S. EPA is unique in the industry in that they take a cooperative, non-confrontational, problem-resolution approach. His reputation as an individual who can obtain positive regulatory results is largely owing to this, both throughout the industry and with the EPA, as well as his ability to see the implications of alternative regulatory tactics and strategies.

Dr. Landis earned his M.S. and Ph.D. degrees in Plant Pathology from Michigan State University, and received his B.S. in Botany from Miami University in Oxford, Ohio.

Lisa Ayn Setliff

Vice President of Regulatory Affairs

Lisa Ayn Setliff joined Landis in 2005 and has served as Research Assistant, Manager, Director and now Vice President of Regulatory Affairs. She is a results-oriented leader with a M.S. in Biotechnology from Johns Hopkins University. Lisa’s primary strengths lie in a broad range of regulatory science disciplines, leadership of regulatory teams, and strategic scientific and administrative solutions to difficult challenges in the regulatory arena. Lisa advises, supports and assists registrants during all phases of pesticide product development and registration.

Prior to joining Landis, Lisa worked at Cambrex, a biotechnology company in Walkersville, MD, as a Senior Research Assistant. While at Cambrex, Lisa worked closely with the FDA and conducted research which was vital for the development of pharmaceutical agents. Prior to Cambrex, she worked at the Johns Hopkins School of Medicine in a glaucoma laboratory performing neurobiology research for 10 years and successfully secured millions of dollars of NIH (National Institute of Health) grants for research and published several peer-reviewed journal articles.

In her 16-year tenure at Landis, Lisa has developed successful registration packages for new and existing chemicals for a broad range of clients, reduced risk petitions, risk assessments necessary for EPA registration, in-depth science documentation to achieve reassessment of tolerances and tolerance exemptions, inert ingredient petitions, reregistration packages, OECD dossiers and registration packages for new end use products. Lisa acts as a study monitor for laboratory studies and as a product manager for various chemicals. Lisa has also assisted clients with a partnership with IR-4 in order to achieve registration of minor use crops. Upon client request, Lisa works as a liaison between registrants and their marketing partners.

Some of Lisa’s greatest achievements at Landis have been securing reduced risk status for multiple active ingredients and successfully leading six new active ingredients through the review process. In the registration of these six new active ingredients, Lisa developed excellent working relationships with both the regulatory authorities (EPA, PMRA, APVMA, and CRD) and the clients.

Lisa has an office in North Carolina; therefore, she can easily attend meetings in RTP and at the EPA.
