Robert L. Buchanan is affiliated with the University of Maryland, College Park in the United States. Their research spans multiple domains within agricultural and biological sciences as well as biochemistry, genetics, and molecular biology. The main focus is on food safety, microbial pathogens, and plant sciences, with a significant portion of work related to biotechnology and food science.

The scientist's research contributions address several critical topics, including:

  • Listeria monocytogenes in Food Safety
  • Food Safety and Hygiene
  • Salmonella and Campylobacter epidemiology
  • Microbial Inactivation Methods
  • Viral gastroenteritis research and epidemiology
  • Enterobacteriaceae and Cronobacter Research
  • Light effects on plants

They have published extensively in a variety of scientific venues. Most publications appear in the Journal of Food Protection, followed by contributions to Food Microbiology, the Journal of Food Science, Current Opinion in Food Science, and the Journal of Plant Physiology.

Recent notable papers include:

  • "Microgreen nutrition, food safety, and shelf life: A review" (2020) in the Journal of Food Science
  • "All food processes have a residual risk, some are small, some very small and some are extremely small: zero risk does not exist" (2021) in Current Opinion in Food Science
  • "Fungal pathogens of cereal crops: Proteomic insights into fungal pathogenesis, host defense, and resistance" (2021) in Journal of Plant Physiology
  • "Survival of Salmonella in Various Wild Animal Feces That May Contaminate Produce" (2020) in Journal of Food Protection
  • "Identification and Subtyping of Salmonella Isolates Using Matrix-Assisted Laser Desorption-Ionization Time-of-Flight Mass Spectrometry (MALDI-TOF)" (2022) in Microorganisms

Collaboration plays a significant role in their research output. Frequent coauthors include Chongtao Ge, R.C. Baker, Rohan V. Tikekar, Michelle D. Danyluk, and Qiao Ding, several of whom have coauthored multiple papers.

The scientist's work integrates expertise in biotechnology and food safety applied to agricultural and biological sciences. This includes investigating microbial hazards in food systems, microbial inactivation technologies, and pathogen epidemiology related to foodborne illnesses. The intersection of plant science and food microbiology is also evident in their investigations of fungal pathogens and nutritional quality in plant-derived food products.
