Human Nutrition Laboratories
The human nutrition laboratory is designed to provide facilities for faculty, students and staff to perform cutting-edge research in the area of human nutrition. The laboratories are organized in the following divisions:
- Foods Laboratory
- Human Nutrition Research Laboratory
- Bio-nutrition Research Laboratory
Associated Faculty

- Dr. Florian Cerklewski
- Dr. Mary Cluskey
- Dr. Emily Ho
- Dr. Urszula Iwaniec
- Dr. Melinda Manore
- Dr. Carolyn Raab
- Dr. Maret Traber
- Dr. Russell Turner
Foods Laboratory
One classroom laboratory is available housing 9 individual units each including range/stove, sink, storage and counter space. They are utilized for student to conduct food related experiments and preparation of food items in three undergraduate courses. One refrigerator and an adjacent dining room are also available.
A larger lecture/laboratory classroom is available with seven stove/sink/counter units. This room also provides seating for 40 people, a demonstration table and seating for approximately 40 people. This room is utilized for lectures and for small group activities which may involve using foods and/or demonstration based lectures. One refrigerator is available in the room.
A controlled feeding study lab (see Human Nutrition Research Laboratory) is available that provides five preparation stations, tables and a dining area for subjects who are participating in diet or controlled feeding studies.
A food storeroom provides storage for dry goods, cold storage dishware and equipment utilized in the foods laboratories.
Human Nutrition Research Laboratory
The Human Nutrition Research laboratories provide facilities and opportunities for nutrition assessment, dietary interventions and other translational/clinical studies. The facilities are equipped with a Medical Feeding unit (with full kitchen & dining area), sample preparation areas and diet analysis computers to facilitate human nutrition research projects.
The Medical Feeding Unit of the Human Nutrition Research Laboratories have been designed to be a pleasant environment for subjects to gather for meals, to have their blood samples drawn, and to interact with the investigators. There is an adjacent private, blood drawing room, and an adjacent lab space for sample aliquoting. There are two rooms where subjects can be served. In one up to 20 subjects can be served all their daily meals and snacks. The second room is equipped to give subjects smaller meals, i.e., breakfast after a blood draw. The rooms are designed so that more than one study may be conducted simultaneously. Subjects meet in these rooms to fill out questionnaires, meet with investigators and schedule assessments.
The Human Nutrition laboratory heavily interfaces with the Human Performance laboratory and the Bio-nutrition laboratories for human assessment measures and biochemical/molecular analyses to address numerous research questions relevant to human nutrition.
Bio-Nutrition Research Laboratories
The goal of the Bio-nutrition research laboratories is to interface biological mechanisms with human nutrition to better understand how nutrients promote optimal health. The laboratories are equipped with state-of-the-art equipment to analyze biomarkers of nutrient status and phytochemical analysis, as well as provide facilities that enable use of molecular/cellular approaches to human nutrition and examine diet-gene interactions. Current research projects in the NES focus on oxidative stress in health and disease, the role of micronutrients such as B vitamins and trace element in chronic disease and optimal health, obesity, bone health and cancer chemoprevention (namely breast and prostate cancer).
Facilities/Equipment
Laboratories contain all basic installations such as laboratory benches, desks, deionized water, vacuum, sinks, fume hoods. Small equipment such as pH meters, balances, stirrers, tabletop centrifuges, microfuges, electrophoresis equipment, refrigerators and –80 freezers are present.
In addition, facilities include a complete dedicated tissue culture room with sterile flow-hood, incubators, Coulter counter and microscopy equipment. Analytical equipment including kinetic spectrophotometers, UV/VIS and florescence plate readers, and several HPLC are also available. For molecular analysis, there is a dedicated radio-isotope use area with scintillation and gamma counter, a dedicated RNA prep area with PCR Hood MJ Research Chromo 4- qPCR, Perkin Elmer PCR, Alpha Innotech Gel Imager and Guava Personal Cell Analyzer (flow cytometer). These laboratories also interface with other facilities on campus such as the Environmental Health Sciences Center (EHSC) and the Center for Gene Research and Biotechnology (CGRB) and WM Keck Collaboratory for plasma spectrometry for other specialized equipment and needs.
