The research facilities provided by Iowa State are world-class. All faculty have individually assigned laboratories that allow them to carry out their research located in the Food Sciences building, MacKay Hall and the Human Nutritional Sciences Building. Within these laboratories faculty have access to routine instrumentation (e.g. pH meters, balances, spectrophotometers, microscopes), biosafety and chemical hoods, preparatory equipment (e.g. centrifuges, filters, sieves), and specialized equipment (e.g. GC, HPLC, imaging, PCR). There are two research areas suitable for human subject research in HNSB and the Nutrition and Wellness Research Center located in the Iowa State Research Park which is about 1 mile from campus. These units provide metabolic kitchens with preparatory and storage capability, dining facilities, phlebotomy and subject testing areas (including metabolic cart, indirect calorimetry, BodPod, PeaPod, and DEXA).
