Tong Ding, MS 2017

View Morrini Omolo's profile on LinkedIn

Tong Ding is the 2014 AIC Student Award and F. B. Moore Award recipient during her honor program at University of Minnesota Duluth for B.S. in Biochemistry & Molecular Biology and Chemistry. She joined the Baumler Lab after graduation and completed her M.S. program in Food Science at University of Minnesota Twin Cities in 2017.

Tong’s research project focused on Salmonella, a common foodborne pathogen that may cause severe consequences. To better understand the virulence characters and mechanisms of different Salmonella subspecies, Tong analyzed the genome, protein and reaction information of specific Salmonella strains using computational Genome-scale Metabolic Models. She also conducted experiments to verify the constructed models based on the host specificity property of the microbes.

Holly ReilandHolly Reiland, MS 2016
View Morrini Omolo's profile on LinkedIn

Holly Reiland was an internal Skarra Fellowship recipient. She graduated from the University of Minnesota in May 2014 with a BSc. in Food Science. Holly completed her MSc. Studies in 2016.

Holly participated in many aspects of the Food Science department. She played a pivotal part in writing several published pieces of work (see list below) and she conducted her own undergraduate research project in which she tested protein and carbohydrate supplementation on human subjects while completing an endurance run. She found significant results that showed a heightened degree of GI tract upset upon ingestion of protein supplements prior to an endurance run.

Holly has also studied abroad, participated in International Food Technologist Student Association product development competitions at the national level, and worked in several labs within the food science department.

Holly’s greater interests include combining food science and nutrition into one holistic area of study. She enjoys the chemistry behind constituents and flavors that are found in foods as well as how these constituents interact during metabolism. Her research focused on using computational biology in order to construct a metabolic model that accurately predicts the growth of a segmented filamentous bacteria entitled Candidatus Arthromitus. The model was validated via experiments carried out in the lab. The overall goal of her work was to design a culture medium from the in silico model in order to grow CA in vitro and optimize growth in vitro in order to create a probiotic containing this commensal bacteria.

zachary metzZachary Metz, MS 2016

Zach Metz graduated from the University of Minnesota-Twin Cities in May of 2013 with a Bachelor’s of Chemical Engineering. He completed his Food Science MS in 2016.

His areas of interest are food processing, safety, quality, and product development. His research focused on Listeria spp. with an emphasis on L. monocytogenes an important foodborne pathogen. A genome scale metabolic models were created for several strains of L. monocytogenes and one strain of L. innocua. The models were verified in the laboratory and used to study the differences between strains in food environments that have been known to harbor Listeria. This work leads to a better understanding of Listeria as well as improved methods of controlling its presence in food.

Morrine Omolo, MS 2015

View Morrini Omolo's profile on LinkedIn

Morrine Omolo is a Zawadi Africa Educational Fund Scholar and the 2012 Fairleigh Dickinson University Pinnacle Award and International Undergraduate Student Award recipient. She graduated from Fairleigh Dickinson University in May 2012 with a BSc. in Biochemistry, and completed her MSc. Food Science at the University of Minnesota in 2015.

Her areas of interest are food safety, processing and packaging. With the increased use of artificial preservatives in the food industry, the discovery of naturally occurring alternatives would be invaluable to food scientists. Her MS research focused on the antimicrobial activity of over 90 types of chili peppers, and the potential for their use as food preservatives. The antimicrobial activity of these chili peppers are currently were tested against virulent food borne pathogens such as Salmonella spp., Listeria spp. , and E. coli.
