David Beyer, PhD
David works with the mushroom community here in North America and Europe. His grower education extension program develops and conducts workshops and farm visits to provide assistance on many different aspects of mushroom cultivation. The focus of his research is looking at cultural factors influencing disease development to help minimize the impact of mushroom diseases and screening existing and potential new fungicides to maintain and improve the efficiency of the few pesticides the industry have left in their arsenal.

Carolee Bull, PhD

Originally a Pennsylvania native, Dr. Bull graduated with a degree in Botany at Ohio University in 1985. Work with a mycologist and courses in mycology and microbiology transformed her interest in botany to a passion for plant pathology. She received an MS in Plant Pathology from Washington State University in 1987, and a PhD in Plant Pathology from Oregon State University in 1992. Her work on biological control of plant pathogens and phytobacteriology continued as a NSF Postdoctoral Fellow in Switzerland. For the past 20 years she worked for the USDA?ARS in California to develop alternatives to chemical pesticides for vegetable and small fruit production. Dr. Bull served on the Administrative Council for the Western Sustainable Agriculture Research and Education Program and was key to the development of organic research programs at the USDA/ARS. For outstanding mentorship women and Latino student research interns, she received the Secretary's Honor Award (the highest award service to the nation in agriculture) from the USDA Secretary Thomas Vilsack.

Meghan Klotzbach
Meghan is a fifth generation member of the Yeatman Family. She graduated from Dickinson College in 2008 and has worked for Mother Earth Organic Mushrooms since 2012. She began her journey working with the Quality Assurance Department, taking on many projects for Food Safety and Food Defense. She now holds the title of Regulatory Manager, specializing in Organic Certification, Employee Safety, OSHA and Human Resources Compliance for their Farms and Packing facility. 
Lise Korsten, PhD

Professor Korsten is currently the Co-Director within the Department of Science and Technology, Centre of Excellence Food Security. She is also responsible for the food safety and regulatory control programs within the DST Centre of Excellence Food Security. She is a chief editor of Crop Protection and is chairing the International Society for Plant Pathology Task Force on Global Food Security.

Professor Korsten has focused her research mainly on complementary fields of post harvest technology and food safety as related to international trade in fresh produce. She has been able to establish research teams in food safety, post harvest pathology, biocontrol and mushroom and fruit health. As a team they have been able to develop several innovative technologies to reduce diseases and prevent product contamination. The value of her research programs can best be illustrated by sustainable industry financial support. She has been able to attract extensive national and international long term funding such as the Water Research Commission solicited research projects “An investigation into the link between water quality and microbiological safety of fruit and vegetables from the farming to the processing stages of production and marketing” and “Evaluation of the risks associated with the use of rain water harvested from roof-tops for domestic use and homestead food gardens, and groundwater for domestic use and livestock watering” as well as the 7th EU Framework project “Impact of climate change and globalization on safety of fresh produce – governing a supply chain of uncompromised food sovereignty.

Professor Korsten has also developed one of the first biocontrol products in South Africa in 1992 that was patented, registered and commercialized and is still used in the fruit industry. An alternative mushroom casing material has also been developed by her team using waste products that has since been licensed for commercial production.

Luke LaBorde, PhD

His current research interests include finding ways to minimize contamination of produce packing houses and food processing facilities with Listeria monocytogenes and other harmful microorganisms.  Luke's extension activities center on food safety and sanitation curriculum development for agricultural producers, packers, and processors of fresh and minimally processed produce. Most recently, his activities have included assisting the Pennsylvania food industry meet new regulatory requirements issued under the U.S. Food Safety Modernization Act.

Paul Patterson, PhD
The central theme of Dr. Patterson's extension and research programs is environmental poultry management. Efforts focus on discovering and promoting efficient poultry production systems that place minimum burden on the environment. While managing manure and by-products of poultry production are obvious endeavors, less tangible efforts include the impact of odor, flies, traffic, etc., on the environment at the urban-rural interface. The later impacts are important to the sustainability of poultry production and processing enterprises in Pennsylvania. Other efforts are geared to enhancing producer profitability and improving egg production, quality, and food safety.

Research efforts have focused on environmental poultry management with an emphasis on applied studies that go hand in hand with the extension programs. As a nutritionist I have sought to recycle the nutrients of poultry by-products to both crop and livestock systems to abate non-point sources of pollution. These efforts benefit small poultry farmers, corporate agriculture, and ultimately the public at large.

He has been a member of the faculty at Penn State since 1989. He has a B.S. and Ph.D. in Agronomy from Penn State University and a M.S. from Virginia Tech. In his position as the extension grain crops specialist, he develops educational programs for extension agents, agribusiness groups and producers on timely issues such as potential of corn hybrids for silage production, small grains for forage production and management tactics for corn for silage. His research has complemented his extension program, and is often targeting issues at the plant/animal interface in the diversified agriculture in Pennsylvania. He helps to direct the Penn State variety evaluation trials for corn, corn silage, wheat, soybeans and barley. He has also led the development and commercialization of an interseeding machine to expand the potential of cover cropping for corn and soybeans.
