Biography
I am an Assistant Professor in the Division of Nutritional Sciences at Cornell University. I received a B.S. in chemistry from Butler University in 2000 and a Ph.D. in Biochemistry, Molecular and Cell Biology from Cornell University in 2007.
Research interests
The Field research group uses several in vitro and in vivo model systems to study the mechanisms that underlie physiological outcomes associated with perturbed one-carbon metabolism. Impaired folate-dependent one-carbon metabolism is associated with adverse physiological outcomes that include certain cancers, cardiovascular disease, neurological impairments, and birth defects. More specifically, the Field laboratory is interested in the contributions of folate and vitamin B12 nutrition to supporting mitochondrial DNA precursor synthesis with a focus on understanding how folate and B12 affect mitochondrial DNA integrity and support mitochondrial function, especially as related to development of chronic diseases and age-related decline in mitochondrial function.
The Field research group also works on understanding the metabolism of erythritol, which is a newly discovered product of human glucose metabolism through the pentose phosphate pathway. This is important because elevated plasma erythritol has recently emerged as a predictive biomarker of weight gain, type 2 diabetes, and cardiovascular disease. We have identified key pentose phosphate pathway enzymes that regulate endogenous production of erythritol from glucose. The lab is currently using model systems to understand how obesogenic dietary exposures and common genetic variants interact to affect endogenous erythritol synthesis and whether metabolism of glucose to erythritol is causally related to cardiometabolic disease development.
My laboratory studies gene-nutrient interactions that lead to development of disease. It is clear that what we eat can be associated with disease onset, and some individuals are more likely to be affected based on certain genetic, or inherited, characteristics. We investigate these interactions at a molecular level, with the ultimate goal of designing interventions that prevent disease and improve human health.
Impaired folate-dependent one-carbon metabolism is associated with adverse physiological outcomes that include certain cancers, cardiovascular disease, neurological impairments, and birth defects. Our laboratory uses several in vitro and in vivo model systems to study the mechanisms that underlie physiological outcomes associated with perturbed one-carbon metabolism. More specifically, we are interested in understanding the contributions of folate and/or vitamin B12 nutrition and enzyme localization in supporting mitochondrial DNA precursor synthesis, with a focus on understanding how folate nutrition affects mitochondrial DNA integrity and pathogenesis of metabolic diseases such as mitochondrial DNA depletion syndromes, chronic disease, and age-related decline in mitochondrial function.
Recently, our research has also focused on the metabolism of erythritol, which is a product of the pentose phosphate pathway and which has recently emerged as a predictive biomarker of weight gain, type 2 diabetes, and cardiovascular disease. We have identified the enzymes responsible for endogenous production of erythritol and are currently using animal models to understand the metabolic pathways underlying the association between erythritol exposure, genetic variants that affect endogenous erythritol synthesis, and central adiposity.
I am currently the instructor for NS3320, “Methods in Nutritional Sciences,” a required course for Nutritional Sciences majors. This laboratory-based course introduces students to the principles and analytical techniques used in nutritional sciences and aims to help students develop skills in data analysis, data interpretation, and scientific writing in addition to mastering basic laboratory techniques that are most relevant to nutrition.
I also supervise undergraduate students in independent research courses including NS4010, and BIO2990.

I served as a member of the writing group for a committee from the American Society for Nutrition (ASN) in producing a report on best practices to facilitate collaboration between academia, industry, and government that ensures rigorous research conduct and transparency between all parties and the public. This report was published in the American Journal of Clinical Nutrition in 2019. In addition, I served as a member of ASN's Committee on Advocacy and Science Policy from 2018-2021, and continued to engage with this group in developing conflict of interest standards for the ASN. I am currently the chair of ASN's "Vitamins and Minerals" research interest group.
