David Edache, MSc, PhD
David Edache, MSc, PhD
Research Manager

David received his Animal Science undergraduate degree from the University of Agriculture Makurdi in Nigeria, where he was born and raised. He later moved to the UK to pursue a MSc degree. While there, he continued his study on ruminant nutrition with a particular focus on mineral supplementation for lambs raised on pasture. After completing his MSc degree in 2019, he accepted a PhD position in Italy where his research was on developmental programming in dairy heifers, specifically looking at the impact of maternal dietary challenge during pregnancy on the development of the gastrointestinal system in the offspring. David has a strong interest for research involving animal models, and his long-term goal is to keep pushing the limits of research in both academic settings and R&D-related enterprises.
Under the supervision of Dr. Natalia Cernicchiaro, David is presently a postdoctoral research fellow. As part of his job, David will look into the antiviral activities of polyphenols isolated from sorghum against the Japanese encephalitis virus (JEV).

Vanessa Horton, DVM, MS, PhD
Vanessa Horton, DVM, MS, PhD
Research and Innovation Associate

Dr. Vanessa Horton received her DVM from Federal Fluminense University, Brazil, in 2017, followed by an M.S. in Beef Cattle Nutrition (2020) and a Ph.D. in Veterinary Epidemiology (2025) from Kansas State University. Currently, Dr. Horton is a Research and Innovation Associate with Heritage Veterinary Partners and the Center for Outcomes Research and Epidemiology (CORE), where her work integrates epidemiologic methods, field data, and stakeholder perspectives to support evidence-based decision-making in livestock systems. Her research interests include animal health and disease, risk mitigation, production efficiency, antimicrobial stewardship, food safety, sustainability and economics, with an emphasis on translating research findings into practical solutions for veterinary and production stakeholders.

David Kiiza, DVM, MS, PhD
David Kiiza, DVM, MS, PhD
Research Associate

David received his PhD in Veterinary Medical Sciences from the University of Florida with a strong focus in epidemiology, infectious disease modeling and economic assessment. He also earned a Master's degree in Veterinary Epidemiology from Murdoch University in Australia and a degree in Veterinary Medicine from Makerere University, Uganda. His research goal focuses on the epidemiology, disease surveillance, one health, infectious disease modeling, risk analysis and animal health economics of zoonotic diseases and transboundary animal diseases. David’s research interests focus on epidemiological studies aimed at understanding the transmission dynamics of infectious diseases, estimating their burden and identifying factors associated with exposure to infectious diseases and quantifying the risk of introduction of transboundary animal diseases in disease-free herds.
David worked in both government institutions and international non-government organizations (USAID, IFAD, UN FAO, FCDO, Global Fund, ENABEL, African Development Bank, European Commission and Heifer International) serving as a team leader, project manager, researcher, development specialist or lead consultant on various projects and programs. David possesses a strong enthusiasm and passion for evidence-based research, aiming to better inform policymakers and facilitate informed decision-making. David is currently working with the Center for Outcomes Research and Epidemiology under direct supervision of Dr. Michael Sanderson.

Karla I. Moreno-Torres, DVM, MSc, PhD
Karla I. Moreno-Torres, DVM, MSc, PhD
Applied Policy Scientist

Dr. Moreno has more than 10 years of experience translating science into emergency preparedness and response.  Her greatest strengths are translational observation and iterative problem-solving, driven by a bi-directional collaboration. She has a talent for simplifying complex systems into decision-supporting frameworks. She is passionate about generating evidence that shapes interventions and policy decisions, and values communication, transparency, and flexibility throughout that process.

She earned her PhD in Epidemiology from the Ohio State University, her DVM and MSc in Wildlife Disease Ecology from the National Autonomous University of Mexico. Dr. Moreno's experience includes a role as an ORISE Fellow at USDA-CEAH-ARS, where she applied her skills in data analysis, visualization, and model parameterization to support animal health emergency preparedness initiatives. In this role, her bilingual proficiency in English and Spanish has been fundamental to training government officials in modeling techniques, thereby facilitating knowledge transfer to diverse stakeholders.

Sarah Schrock
Sarah Schrock
Research Associate

Sarah earned a B.S. in Biology from Olivet Nazarene University in 2012 and an M.S. in Epidemiology from the University of Colorado in 2016. She has worked as an epidemiologist at National Jewish Health in Denver, Colorado, and with the New Mexico Department of Health, where her work focused on maternal and child health. In 2025, she completed an M.S. in Wildlife and Fisheries Science, with an emphasis on wildlife health and disease ecology, including field-based research.

Her research has focused on modeling temporally and spatially dynamic host–pathogen interactions. She is broadly interested in approaches that connect human, domestic animal, and wildlife health, reflecting a One Health perspective.

Golam Shakil, PhD
Golam Shakil, PhD
Postdoctoral Fellow

Golam received his Ph.D. in Economics from Washington State University. He worked as a postdoctoral researcher at the Paul G. Allen School for Global Health, where he worked on the Global Burden of Animal Diseases and USDA-APHIS–funded analyses of Highly Pathogenic Avian Influenza control strategies. He is currently a Postdoctoral Fellow at the Center for Outcomes Research and Epidemiology (CORE), focusing on modeling foot-and-mouth disease outbreaks in cattle and evaluating their economic impacts. His research interests include economic modeling of animal health systems, econometrics, and the integration of epidemiological data into economic frameworks.

Stephen Edache, DVM, MSc
Stephen Edache, DVM, MSc
PhD, Pathobiology (Epidemiology)
  • Advisor: Dr. Natalia Cernicchiaro

Stephen received his DVM from Nigeria in 2021 and his MS degree from Kansas State University. His MS research focused on assessing Salmonella enterica burden and control measures in dairy Cattle. His PhD program focuses on understanding and modeling the transmission of Japanese encephalitis virus so as to suggest effective measures of preventing its introduction and spread in the United States. His passion has always been to transfer theoretical knowledge and practical skills gained to students for the attainment of their academic and professional goals.
