UD Degree: Ph.D. in Plant and Soil Science
Dr. Gordon Johnson began his career with UD Cooperative Extension in 1994 as a Horticulture and Specialty Crop Agent in Kent County, adding the role of Agronomic Crop Agent in Kent County in 1997, and becoming the statewide Dairy Agent in 1999. In these roles, he taught ornamentals short courses, initiated the Kent County master’s series for field crops, conducted workshops on fruit and vegetable production, and developed programs in organic farming, dairy records, agritourism, entrepreneurship and business management. Gordon facilitated the development of Delaware’s Nutrient Management Program and initiated statewide produce food safety education. He also was one of the first agents to integrate electronic outreach into his work and he maintained a commercial agriculture and commercial horticulture blog.
In 2010, Gordon became the Extension Fruit and Vegetable Specialist and a faculty member in our Department of Plant and Soil Sciences. He serves as a liaison and advisor to the vegetable and fruit industry in Delaware and provides targeted training and updates with an emphasis on produce food safety. He also conducts applied research on vegetable, fruit, and specialty horticulture crops.
Gordon received his Ph.D. in plant science from UD. Following a long and rewarding career, he is retiring in June 2023 but will continue to teach and work on selected research and outreach projects.

UD Degree: M.S. Soil Sciences
Dr. Mary Stromberger is the Vice Provost and Dean for Graduate Education at The Ohio State University, supporting more than 11,000 students enrolled in master’s and doctoral programs. She holds a student-centric vision for graduate education and believes that a thriving graduate school is one that mentors students, advances belonging, strengthens relationships, and bolsters collaboration across the university. Mary also holds the ENGIE-Axium Endowed Chair.
Prior to her arrival at OSU, Stromberger was the Vice Provost of Graduate Affairs and Dean of the Graduate School at Colorado State University, Fort Collins, CO, where she supported over 6,000 graduate students in all aspects of graduate education, research, teaching, and well-being. At CSU, she championed graduate student support and inclusion, and established the CSU’s Graduate Center for Inclusive Mentoring which provides mentor training to faculty and students, hosts social activities, and supports recruitment and retention of students from underserved populations. Stromberger has grown professional doctorate and PhD programs, increased support of graduate interdisciplinary programs, and updated policies and procedures that have improved student experience and staff culture.
Stromberger joined CSU in 2001 and was a tenured faculty member in the university’s Department of Soil and Crop Sciences. Mary is nationally and internationally recognized for her research on plant-root microbiomes, soil ecosystems and soil health. She earned a bachelor’s degree in biology and microbiology at West Chester University, master’s degree in soil science at the University of Delaware, and Ph.D. in soil science at Oregon State University.
UD Degrees: M.S. Entomology, Ph.D. Entomology and Wildlife Ecology
Dr. Ellen Lake is the director of conservation and research at Mt. Cuba Center in Hockessin, Delaware. She leads a team that documents the ecological benefits and horticultural performance of native plants, studies the impact of adaptive management and restoration strategies, inventories and monitors flora and fauna, develops propagation and production protocols for native plant species and further develops Mt. Cuba’s living collections.
Lake developed her love of the outdoors through an environmental education summer camp run by the Brandywine and Red Clay Valley Associations, now the Brandywine Red Clay Alliance. She worked for those organizations in a variety of roles between 1990 and 2004, ultimately serving as their education director. She earned a bachelor’s degree from Bryn Mawr College with a double major in biology and anthropology, a master’s degree in entomology and a Ph.D. in entomology and wildlife ecology from the University of Delaware, where she researched biological control of mile-a-minute weed and how to integrate weed management techniques to restore invaded sites.
After graduate school, Lake was a visiting assistant professor at The College of New Jersey. She then joined the USDA Agricultural Research Service Invasive Plant Research Laboratory in Fort Lauderdale, Florida, where she was a research entomologist. Her research focused on biological control of invasive weeds in the Greater Everglades ecosystem.
Lake has authored 49 refereed publications and contributed to the acquisition of more than $4.6 million in research funding. She served on the boards of the North American Invasive Species Management Association, Florida Invasive Species Council and Brandywine Valley Association. Her research interests include restoration ecology, integrated weed management, biological control and plant-insect interactions.
UD Degrees: B.A. Biological Science, M.S. Animal Science, Ph.D. Animal Science
Dr. Milos Markis is the owner and president of AviServe LLC, an independent avian diagnostic and research laboratory in Newark, Delaware. Markis was born in Croatia and immigrated to Newark, Delaware, with his mother and brother at the age of 12. Markis received a bachelor’s degree in biological sciences with a minor in chemistry, master’s degree in animal science and Ph.D. in animal science, all from the University of Delaware. During his undergraduate studies, he worked as a laboratory assistant in Dr. Robin Morgan’s research laboratory and fell in love with poultry research. His graduate research focused on the detection of the vaccine and wild-type Marek’s disease viruses and host and viral microRNAs in the feather tips. He later conducted research with Drs. Jack and Sandy Rosenberger at AviServe LLC, where he investigated the roles of reovirus, astrovirus and adenovirus in viral enteritis/enteropathy in chickens. The opportunity to be mentored by Dr. Morgan and Drs. Rosenberger allowed Markis to learn both classic and molecular virology, which proved invaluable for his future career. Following graduation, Markis continued to conduct research at AviServe LLC on emerging and evolving poultry pathogens of economic significance to the poultry industry. Markis is a member of the Delmarva Chicken Association, World Veterinary Poultry Association and American Association of Avian Pathologists, serving in different capacities on the History, Awards, Enteric Disease and TIME committees.
