Eli AsemElikplimi (Eli) K. Asem

Professor of Physiology

Dr. Elikplimi (Eli) Asem grew up in Ghana, West Africa and received his DVM degree in 1980 from the Szent Istvan University, School of Veterinary Sciences in Budapest, Hungary. He then received his Ph.D. (Medical Physiology) in 1985 from St. Louis University School of Medicine, St. Louis, Missouri. From 1985 to 1986 Dr. Asem was a postdoctoral fellow in the Reproductive Biology Unit, Department of Obstetrics and Gynecology, Ottawa Civic Hospital/University of Ottawa, Ottawa, Ontario, Canada, from 1986 to 1989. 

Dr. Asem came to Purdue in June 1989 as an Assistant Professor in the School of Veterinary Medicine. He is a Professor of Physiology and teaches physiology and pharmacology to veterinary, graduate and medical students. Dr. Asem has served in senior leadership positions in the College of Veterinary Medicine from 1997 to 2007.

Chip BlatchleyErnest (Chip) R. Blatchley III

Professor of Civil Engineering and Environmental and Ecological Engineering

Professor Blatchley teaches and conducts research in the area of physico-chemical processes of environmental engineering. The primary focus of his research activities is on water treatment processes, especially those that involve disinfection. His group conducts investigations of the chemistry and process behavior of disinfection systems. In recent years, Professor Blatchley’s research and teaching have expanded to address the issue of water supply in developing countries. His group is developing water treatment technologies that are appropriate for developing countries. In addition, the Blatchley group is examining sustainable water treatment practices for use in developing countries. A related activity is an interdisciplinary class entitled “Water Supply in Developing Countries” that involves faculty and students from six academic disciplines (Civil Engineering, Environmental Engineering, Agricultural Economics, Food Science, Biology, and Nursing). This class, which follows the service-learning model, has a goal of designing, building, and implementing sustainable community-scale water treatment systems in developing countries.  The first of these systems was built and implemented in June 2014 in Las Canas, Dominican Republic. Current and future iterations of this class will involve similar design/build/implementation sequences in other communities in the DR, and perhaps other countries.

Sylvie BrouderSylvie M. Brouder

Professor of Agronomy and Horticulture
Director, Water Quality Field Station

Sylvie Brouder’s current research addresses implications of converging U.S. biofuel and food security agendas by developing field-to-landscape analyses of the potential for dedicated energy crops to provide renewable fuel on marginal lands while protecting natural resources and food or feed productivity. She directs Purdue’s Water Quality Field Station and is responsible for developing and promoting agro-ecology programming campus wide. A core theme of Brouder’s research and the field station’s research portfolio is quantitative assessment of synergies and tradeoffs among productivity and environmental objectives to inform development of policy that promotes agricultural sustainability. She specializes in crop mineral nutrition with an emphasis on crop ecology, water quality and agro-ecosystem nutrient balances and losses. In her research, she concentrates on nitrogen, carbon and potassium, evaluating the practicality of systems and management practices, and ecological viability and sustainability, including influences on water quality and greenhouse gas emissions from agricultural soils. Brouder earned a doctorate in ecology from the University of California, Davis, and a bachelor’s degree in biology from Harvard University.

Connie WeaverConnie M. Weaver

Distinguished Professor of Nutrition
Head of the Department of Nutrition Science

In 2013, she was bestowed the honor of the Spirit of the Land Grant Award.  In 2012 she was selected as the Herbert Newby McCoy recipient. This award is the most prestigious research honor given by Purdue University. In 2010 she was elected to membership in the Institute of Medicine of The National Academies, of which she is a member of the Food and Nutrition Board. Also, in 2010 the Women's Global Health Institute (WGHI) was formed at Purdue University. As founder and director, Dr. Weaver oversees the mission of improving the health of women globally through research and training by proactively identifying the causes and prevention of diseases related to women. In 2008, she became Deputy Director of the National Institutes of Health funded Indiana Clinical and Translational Science Institute. From 2000 to 2010, she was Director of the NIH Purdue-UAB Botanical Research Center to study dietary supplements containing polyphenolics for age-related diseases. Her research interests include mineral bioavailability, calcium metabolism, and bone health. Dr. Weaver was appointed to the 2005 Dietary Guidelines Advisory Committee for Americans. She has published over 260 research articles.

Cliff WeilClifford F. Weil

Professor of Agronomy

Dr. Cliff Weil earned his doctoral degree in Genetics and Development from Cornell University in 1984. Cliff serves on the faculty at Purdue University. He teaches an undergraduate Introductory Genetics course, and graduate courses in Advanced Plant Genetics and in Genomics. He is also a member of the Whistler Center for Carbohydrate Research, a group including food chemists, engineers, and biophysicists working with food and ingredient companies around the world to bring advances in carbohydrate research to bear on food and industrial problems, improvements and development. Dr. Weil's lab works on using genetics and genomics for cereal crop improvement, largely in maize and sorghum. He and his lab team are primarily interested in understanding how to improve the digestibility of the starch and protein in the grain for food and feed uses. They are also looking at the basic genetic controls that determine how, when and where sugars move throughout the plant, a central question for both development and yield. As part of these projects they have been involved in developing some of the world’s largest-scale genetic mutant resources in both maize and sorghum for deployment to these communities worldwide. These have allowed them, and others, to begin looking at a wide range of biological questions (nutritional quality, morphology, metabolism, development, signaling, just to name a few) using a combination of forward and reverse genetic approaches.

Laurel WeldonS. Laurel Weldon

Interim Vice Provost for Faculty Affairs
Director, Center for Research on Diversity and Inclusion
Professor of Political Science

Taking a global perspective, Weldon's work on social movements and public policy explores many themes central to democratic and feminist theory including questions of representation, intersectionality, solidarity, and state-civil society relations. She is an expert on gender and social policy, especially policies on violence against women, but has also written on family law and policy, living wage and anti-poverty policy and employment policy more generally. Weldon's work combines quantitative cross-national and cross-state analysis with comparative case studies and fieldwork. With Mala Htun of the New School, Weldon is currently involved in an NSF-funded project investigating women's rights in 70 countries. Weldon is the author of two books, and a co-editor of the first ever Oxford Handbook on Politics and Gender, (February 2013, Oxford University Press). She also co-edits the journal, Politics, Groups and Identity, published by the Western Political Science Association.
