Patricia A. Cassano, MPH, Ph.D., is Professor and Director, Division of Nutritional Sciences, Professor of Healthcare Policy and Research, Weill Cornell Medical College, and Director of Graduate Studies for the Minor Field of Epidemiology in the Cornell University Graduate School.
Dr. Cassano is an epidemiologist with interests in nutrition and genetics; she has specialized expertise in the etiology of respiratory diseases. Dr. Cassano has methodological expertise in the design, conduct and analysis of analytical epidemiological studies, including long-term prospective cohort studies incorporating biological markers of nutrition and metabolism and molecular markers of genetic variation.
Dr. Cassano is a member of a consortium of genome-wide association studies (GWAS) to investigate the relation of genetic variation to pulmonary phenotypes. She is multi-PI of recently completed NIH-funded study of gene x nutrient interactions in relation to pulmonary function phenotypes (with Dr Dana Hancock, RTI). This work is leading to new discoveries of genetic variants that interact with nutrition, including vitamin D and omega-3 fatty acids, to influence lung function.
Dr. Cassano led the EnHANCE Pilot Study of Cornell freshmen, which identified a biological marker (erythritol) of gain in adiposity in the transition from home to college.
Dr. Cassano led the Respiratory Ancillary Study to the Selenium and Vitamin E Cancer Prevention Trial (SELECT). This randomized trial found that supplementation with selenium attenuated the decline in lung function in cigarette smokers. Further studies are underway to define the genetic contribution to response to vitamin E supplementation, and to study whether benefit from the intervention was modified by genetic traits.
Dr. Cassano's research program is funded by NIH. Research is conducted is in the context of graduate student training and in collaboration with post-doctoral researchers. Dr. Cassano teaches the foundation course in Epidemiology for graduate students on both campuses, including the Graduate School of Cornell University and the Weill Cornell Medical College Translational Science program in Clinical Investigation. She is lead instructor for two team-taught courses, one on grant writing and the other on Translational Research and Evidence-based Policy and Practice in Nutrition.
Dr. Cassano directs the WHO/Cochrane/Cornell Summer Institute on Systematic Reviews in Nutrition for Global Policy Making, which is a collaborative effort among the World Health Organization, Cochrane and the Division of Nutritional Sciences. This Institute, which is in its sixth year, trains about 30 participants from around the world each summer during an intensive two-week training, and includes faculty from WHO, Cochrane and Cornell.
- GWAS of plasma change in vitamin E in response to vitamin E supplementation:
- data from our large, randomized trial of nutrition interventions (supplemental vitamin E [400 mg daily] and/or selenium [200 ug daily]) in relation to pulmonary function decline (3000 men) and risk of COPD and/or asthma (~35,000 men);
- collaborators SELECT study, Fred Hutchinson Cancer Research Center
- Gene x nutrient studies of pulmonary function phenotypes within the CHARGE consortium, under the auspices of NIH R21 funded project (Mulit PIs PA Cassano and D Hancock (RTI)):
- genome-wide x nutrient interaction studies of serum vitamin D, plasma omega 3 fatty acids, dietary omega 3 fatty acids, and dietary pattern in relation to cross-sectional pulmonary phenotypes
- Mendelian Randomization studies to investigate the causality of the observational findings from the studies in #2 above, including cross-sectional association of serum vitamin D and lung function and cross-sectional association of plasma omega 3 fatty acids and lung function
- Systematic reviews of nutrient--disease associations including:
- vitamin D and asthma and psoriasis risk
