About

Carroll-Loye Research

Since 1989

Dr. Scott Carroll and Dr. Jenella Loye have pioneered scientific testing, product development and registration services for insect repellents, organic, natural and low toxicity pesticides, fertilizers and soil amendments.

Carroll-Loye Biological Research provides customized service, superior scientific practice in applied public health and agricultural entomology, and Good Laboratory Practice scientific services. We furnish regulatory and product development advice to facilitate registration under US EPA, PMRA, EU and other regulatory authorities.

We have the academic acumen and industrial experience to maximize your project's:

Relevance
Reliability
Information content
Cost effectiveness

We understand that the needs of our sponsors, whether large or small, are ill-served by a boilerplate approach. Everyone on our team of science and regulatory professionals welcomes discussion to best meet your objectives.

Global in scope, local everywhere

Carroll-Loye has broad expertise in public health, environmental entomology, product development and registration and academic biology. Carroll-Loye utilizes research sites and facilities nationally and throughout the world.

Working with the regulatory community

We work closely with regulatory bodies (EPA, PMRA, EU, FDA, DoD) to define best practices for meeting our sponsor’s needs and for sound science in general. Our in-house practices are integral to the recommendations of US EPA regulatory guidelines for insect repellent efficacy tests.

Is registration my responsibility?

Ensuring product effectiveness and safety, is the responsibility of everyone engaged in the development process.

As a case in point, the rapid spread of West Nile Virus, the unchecked epidemic of Lyme Disease and risks associated with global climate change have raised public awareness of insect repellents as well as expectations for performance and government oversight.

With this increased attention to insect repellents, and the growing concern about liability, businesses are searching for ways to:

reduce risk of poor performance
improve confidence in repellent safety and efficacy determination
fathom and comply with the EPA guidelines
differentiate themselves from the competition

Assuring reliable, effective and safe insect repellents depends on thorough and professional testing. Even if you use deregulated (‘25B’) active ingredients, efficacy should still be properly demonstrated. Carroll-Loye Biological Research can help you to meet your performance and safety goals.

Dr. David Nielsen, Ph.D.

Product Development

David Nielsen has 15 years of experience developing, registering, and commercializing green agricultural technologies for California, the US, and world markets. He liaises frequently with industry leaders and is in frequent contact with state and federal regulatory managers. Dr. Nielsen is skilled in NOP product compliance and organic input material development and registration. In addition to his development and regulatory background and his advanced degrees in entomology and genetics, David has nearly a decade of scientific team leadership experience.

Shawn King, M.S.

Scientific & Regulatory Affairs

Shawn B. King has worked with Carroll-Loye for two decades. He holds a Master's degree in Ecology from UC Davis, with expertise in agricultural systems, restoration and pest management. Shawn provides both scientific and regulatory oversight for our human subject studies, and has unparalleled experience with the US/EPA Human Studies Review Board, Cal DPR, and US/EPA Good Laboratory Practices. Shawn is also an accomplished multi-instrumentalist and earth-building expert.

Dr. G.K. (Ghona) Sangha

Toxicology & Product Registration

Ghona is a toxicology and registration specialist with decades of experience in ecotoxicology, pathology, and regulatory toxicology. Ghona has published extensively in the Handbook of Pesticide Toxicology and has recently been involved in the Global Collaboration for Development of Pesticides for Public Health. At Carroll-Loye, Ghona applies her longstanding knowledge in regulatory affairs, analytical chemistry, and study development to head our EPA and EU antimicrobial registration branch.

Jeff Venturino, B.S.

Director of Operations

Director of Operations Jeff Venturino is a graduate of UC Davis in Political Science and History. As an avid outdoorsman, Jeff combines his intimate personal knowledge of biting arthropods with professional acumen regarding the regulatory processes that govern pesticide testing and the protection of human study participants. He helps oversee the design and conduct of studies for both safety and data quality. Jeff emphasizes technical rigor and new approaches to improve value and to test the latest technologies.

Cassandre Kaplinsky, M.S.

Field Director

Cass uses her background in field biology, ecology, and animal behavior to help design
and conduct field studies at CLBR. She received her Master's degree in 2018 from the Roehampton University in London on the influence of climate disasters on tropical primate social systems. Her experience working with animals ranging from wasps to monkeys in a wide diversity of environments helps us to perform accurate and effective field studies throughout the world.

Ralph Washington jr., M.S.

Senior Entomologist

Ralph's professional focus on mosquito biology. He received his Master's degree in Entomology from UC Davis in 2017. He captains of the World Champion UC Davis Linnean Games Team, which under his leadership has dominated that premier academic insect trivia competition since 2015 . When he's not identifying mosquitoes in the field and rearing them in the lab, or memorizing cutting edge facts, Ralph is an in-demand public speaker and science educator.

Corwin Parker, Ph.D. Candidate

Senior Field Technician

Corwin is a broadly trained entomologist with expertise in ecology and taxonomy. He's high energy and always ready for sharp and muddy sides of field work (unless there's poison ivy/oak). At the same time Corwin is incredibly precise and efficient. He's a fourth-year PhD candidate at the University of California Davis studying bark beetle ecology and insect-nematode interactions. Corwin is also a fine artist.

Trevor Fowles, Ph.D. Candidate

Senior Entomologist

Trevor Fowles designs and facilitates both lab and field studies. He's a keen observer of insect behavior, adding his entomological insights to develop biologically meaningful assays in our wind tunnel trials, host choice experiments, and field efficacy studies. Trevor has worked at Carroll-Loye since 2005, and is now also in the third year of a Ph.D. program in Entomology at University of California, Davis (across the street).
