Sara Arscott, PhD, CCRP Manager of Clinical Research

As the manager of clinical research, Dr. Arscott works closely with the Director of Research and Development to identify and prioritize clinical evaluation of existing Standard Process products for safety and effectiveness. Dr. Arscott coordinates the design and preparation of clinical research protocols, assists in negotiations with external investigators and research sites, and oversees the conduct, coordination, and monitoring of clinical trials.

  • Before joining Standard Process in 2012, Dr. Arscott worked at the University of Wisconsin-Madison where she continued her doctoral investigations of provitamin A carotenoid bioavailability and coordinated two international maize provitamin A efficacy trials in south-central Africa.
  • In 2009, Dr. Arscott received a doctorate in Nutritional Sciences from the University of Wisconsin-Madison where she researched fruit and vegetable provitamin A carotenoid efficacy. These efforts were published in Experimental Biology and Medicine, the Journal of Agricultural and Food Chemistry, and Comprehensive Reviews in Food Science and Food Technology.
  • In 2006, Dr. Arscott received a master’s degree in Nutritional Sciences from the University of Wisconsin-Madison. Her work on selenium biofortification of vegetables was published in HortScience.
  • Dr. Arscott graduated from the University of Wisconsin-Madison in 1994 with a bachelor’s degree in Cartography and Geography. She pursued a profession in Geographic Information Systems for 9 years before changing career directions to pursue advanced degrees in nutrition.

Brandon Metzger, PhD Manager of Research and Development Innovation

As innovation manager, Dr. Metzger leads efforts to improve processing, develop new raw materials, and evaluate new farm crops. Dr. Metzger also supports manufacturing improvements through interdepartmental collaboration with engineering and quality control validation studies. His team is tasked with ensuring optimal retention of whole food bioactives from seed to supplement using analytical tools and state-of-the-art pilot manufacturing laboratory equipment.

  • In 2008, Dr. Metzger received a doctorate in nutritional science from the University of Wisconsin-Madison.
  • In fall of 2002, Dr. Metzger enrolled in the University of Wisconsin-Madison's nutritional science doctoral program where he studied in the department of animal science. His work focused on evidence-based research of nutritional supplement ingredients for the prevention of cardiovascular disease. He also published research on hypocholesterolemic buckwheat protein fraction, anti-inflammatory carrot polyacetylenes, and modulation of serum lipids with nutritional supplements.
  • Before joining Standard Process in 2000 as a laboratory scientist, Dr. Metzger worked for two years on the development of echocardiography and MRI contrast agents in the biotechnology industry.
  • Dr. Metzger graduated from Northern Michigan University in 1998 with a bachelor’s degree in biochemistry.

Jon Rykwalder, MS Coordinator of Product Development

In his current role as Coordinator of Product Development, Jon’s primary function involves managing the day-to-day activities required to develop new products and reformulations of existing products.  The process addresses key development stages and tasks, which requires Jon’s involvement in guiding the related activities of almost all departments.  He is involved with formulation, ingredient vendor identification, qualification, and selection, formula and manufacturing feasibility assessment and troubleshooting, process scale-up, as well as assessing new equipment and process opportunities.  Additionally, Jon functions as the coordinator for materials used in clinical trials, which involves placebo formulation, manufacturing and packaging, and shipment of materials to clinical sites.

Jon began his career with Standard Process in March 2003 and worked in QC Microbiology at various levels prior to his transition to the Research and Development team in 2007.

  • In 2007, Jon received his master’s degree in biotechnology from the University of Wisconsin-Madison.
  • In 2002, Jon graduated from the University of Wisconsin-Whitewater with a bachelor’s degree in biology/cell physiology

Lori Hammon Research Specialist

Lori has been a team member of the research and development (R&D) department for the last 11 years. Prior to that, she worked for 7 years in the quality control department. As a Research Specialist, Lori’s expertise covers a broad range of responsibilities including operation of specialized equipment and spectrophotometers for analysis of raw materials and products. Lori works closely with other researchers and scientists in the lab to develop new testing methods and run continuous monitoring studies of raw material and process quality. Lori also has a significant role in general lab operations, assisting new product development, and processing of farm raw materials for analysis.

Chris Scholl Researcher

Chris joined Discovery Science in 2006 as an intern while pursuing his biology/chemistry bachelor’s degree from the University of Wisconsin-Whitewater. After graduating in 2008, Chris joined the team full time and now works mainly on new methods for analysis of phytochemicals and nutrients in foods. He has particular interest in the analytical chemistry aspects of the lab and is in charge of the laboratory mechanical maintenance.


Amber Thompson Researcher

Amber joined the discovery team in 2008 as an intern while pursuing her associate degree from the Madison Area Technical College. After working in quality control as a microbiologist, Amber rejoined the R&D team in 2011. As a researcher, Amber supports the Senior Nutrition Scientist with biological assays, as well as conducts assay development, performs cell culture experiments, and helps to ensure good manufacturing practice compliance within R&D. Amber graduated from the University of Wisconsin – Milwaukee with a Bachelor of Arts degree in psychology where her efforts culminated in a publication in the journal Pharmacology Biochemistry and Behavior.
