Dr. Yakov A. Pachepsky is a soil scientist with a uniquely productive research career.  His research in soil physics and environmental quality has contributed significantly to a better understanding of water and solute transport in soils and landscapes. Pachepsky is nationally and internationally recognized for his research, leadership, and innovative insights on modeling the sources and fates of non-point source pollution and evaluating their impacts on soil, water, and environmental quality.  He has led multidisciplinary research in several areas that developed techniques to simulate and control the sources of chemical movement in soils and landscapes.  He has been part of planning and assessment of soil and water quality research at the international, national, regional, and state level. Dr. Pachepsky has given seminars, short-courses, and presentations in some 25 different countries throughout the world, has organized numerous professional workshops, symposia, and technology

symposia, and technology transfer events, and has conducted work on collaborative projects with several government agencies. He has provided research leadership as the soil physics laboratory director, as a well as member of numerous teams that have reviewed research soil and water programs. He is the Fellow of the ASA and SSSA since 1992, the chair-elect of the SSSA Soil Physics Division, an associate editor of the Soil Science Society of America Journal, the Vadose Zone Journal, member of Editorial boards Geoderma, Catena, Ecological Modeling, International Agrophysics, and Land Degradation and Development. Pachepsky has supervised or has been on committees of more than 30 graduate students. Dr. Pachepsky has made significant contributions to our knowledge of soil physics as well as many contributions related to crop modeling, conservation tillage, irrigation management, fertilizer leaching, soil and crop sampling technology and other practices which have improved agriculture in the US and throughout the world  

Dr. Ronald Fayer has achieved worldwide recognition from peers in agriculture, veterinary medicine, and public health for discoveries of the biology, epidemiology, and control of three major parasitic diseases of livestock and humans. His pioneering development of cell cultures for testing of drugs against coccidiosis, a disease of livestock and poultry with annual U.S. losses in excess of $600 million, led to its widespread use for drug screening by pharmaceutical companies. He led teams that discovered the sources and ultimately the control of Sarcocystis parasites responsible for muscular and intestinal disease in humans, poor

growth and death in livestock. Concepts from those studies have been applied to solving worldwide diseases of cattle, sheep, pigs, and horses. Through his national and international collaborations molecular methods were developed enabling detection of Cryptosporidium affecting livestock health and the safety of food and drinking water. As president of three national scientific societies and editorial board member of five scientific journals he has been devoted to promoting high ethical standards and high quality research in his field.
