About Liz

Dr. Liz Walsh is a Research Scientist with the USDA-ARS laboratory in Baton Rouge, Louisiana. Liz is currently working on various projects which include examining: aggression vs irritation in various honey bee stocks, drone reproductive health and biology, queen reproductive health after stressor exposure, and honey bee variation in responses to pathogens (chalkbrood and Nosema).

She completed her postdoctoral fellowship with Dr. Steve Pernal, of Agriculture and Agri-Food Canada, at the Beaverlodge Research Farm in Alberta. Liz’s postdoc was spent exploring the links between honey bee health challenges and honey bee biomarkers as a part of the national BeeCSI project, but she also did work with AFB and chalkbrood exploring stock variation, asymptomatic vs. symptomatic infections, and more. This was all very different than her dissertation work, which was done at Texas A&M University with Dr. Juliana Rangel where Liz explored the impact of miticide exposure in immature queens. Liz is pleased to be well into her “teenage” years as a beekeeper, since she began keeping bees as a young high school student in her home state of Wisconsin.

About Dan

Dan is a Sr. Principal Scientist, Science Fellow, and pollinator specialist at Bayer CropScience, located in Chesterfield, Missouri, USA. He earned his B.S. in Biology from Messiah College in 2007, followed by a Ph.D. in Entomology with a focus on Apiculture from Penn State University in 2013. Following his graduate studies, Dan completed his post-doc at the University of Florida, where he specialized in pesticide research and Varroa mite management. Dan joined Bayer in 2015 where he has been primarily responsible for pesticide safety evaluations and supporting Bayer’s bee health research initiatives. Dan’s work involves conducting toxicity studies and developing innovative methods and approaches to advance the science of pesticide risk assessment for bees. His research and assessments play a crucial role in ensuring environmentally sustainable use rates and patterns, optimizing application timing, and formulating risk mitigation strategies for Bayer’s crop protection portfolio.

About Rogan

Rogan is a new Assistant Professor at North Dakota State University. He graduated with his Ph.D. from Auburn University in 2025 where he studied Varroa and Tropilaelaps mite management and received his MS from University of Nebraska-Lincoln in 2022 where he looked at the impacts of pesticides on colony functions. The primary goal of his research and extension program at NDSU is to work with beekeepers in North Dakota to minimize honey bee colony losses. North Dakota is the number one honey producing state with hundreds of thousands of colonies moving in every summer. Rogan’s research involves collaborating with commercial beekeepers performing applied research investigating solutions to problems they face with the goal of improving colony health within their operations.

About Daiana

Daiana is a Senior Ecotoxicologist, Regulatory Sciences and Pollinator Specialist at BASF Agricultural Solutions US LLC in Raleigh, NC. She earned a B.S. in Biology from Bahia University of Science and Technology in 2007 and holds a Master’s degree in Entomology and a Ph.D. in Genetics from the University of São Paulo. Her academic background includes five years of postdoctoral research at North Carolina State University, where she studied insect developmental biology, followed by a three-year postdoctoral fellowship in ecotoxicology at Cornell University focused on risk assessment of pesticide exposure to pollinating insects during immature life stages. She joined BASF in 2021 and conducts pesticide safety evaluations while supporting the company’s pollinator research initiatives. Her responsibilities include designing and conducting toxicity studies and developing novel methodologies to advance pesticide risk assessment for bees. Her work informs environmentally sustainable use rates and application practices and supports the development of risk mitigation strategies across BASF’s crop protection portfolio. Daiana is committed to scientific research and innovative initiatives. She is actively engaged with the U.S. Pollinator Research Task Force (PRTF) and contributes to the Physiology, Biochemistry, and Toxicology Branch of the Entomological Society of America.

About Julia

Julia is a Research Entomologist with USDA-ARS where she focuses on insect toxicology and pollinator health. At the moment, her research primarily centers on developing therapeutics and mitigation strategies to enhance honey bee health and performance. She is also interested in identifying and characterizing the effects of stress on aspects of honey bee biology, such as reproduction and behavior, which can be difficult to diagnose.
