“Respect all people, because everyone matters, and great communication creates lasting success.”
Nader Elkassabany is an accomplished regulatory affairs executive, scientist, and strategic leader whose career spans nearly three decades across government, academia, and private industry. Recognized for his expertise in pesticide regulation, animal health, environmental policy, and regulatory strategy, Nader has dedicated his professional life to advancing scientific innovation while ensuring compliance with some of the world’s most rigorous regulatory standards. His rare combination of technical expertise, executive leadership, and firsthand government experience has made him a trusted advisor to global organizations navigating highly regulated industries. Throughout his career, he has consistently demonstrated that sound science, collaborative leadership, and clear communication are the cornerstones of sustainable business success.
Nader’s passion for science began with an exceptional academic foundation. He earned a Doctor of Philosophy in Entomology from the University of Arkansas, complemented by a minor in Microbiology, after completing a Master of Science in Entomology at the University of Tennessee. His graduate research focused on biological control methods and insect science, providing him with an analytical mindset and deep scientific understanding that would later define his professional career. His education cultivated not only technical expertise but also an appreciation for evidence-based decision-making and environmental stewardship that continues to guide his leadership philosophy today.
Following his academic career, Nader joined the United States Environmental Protection Agency (EPA), where he spent approximately fifteen years building an extraordinary record of public service. Rising through progressively senior leadership positions that included Chemical Review Manager, Team Leader, Acting Branch Chief, and ultimately Branch Chief within the Office of Pesticide Programs, he became responsible for leading multidisciplinary teams of scientists, managing regulatory programs, overseeing budgets, directing strategic initiatives, and ensuring compliance with the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). His experience evaluating pesticide safety, environmental risk, toxicology, and antimicrobial products provided him with an unparalleled understanding of the regulatory process from the agency’s perspective.
Nader’s tenure at the EPA also provided significant international exposure. He represented the United States on international regulatory initiatives, served as the EPA lead on ballast water issues with the International Maritime Organization, participated in OECD Biocide Task Force meetings, and helped lead joint regulatory reviews with Canada’s Pest Management Regulatory Agency under the NAFTA framework. These experiences broadened his understanding of global regulatory harmonization while strengthening his ability to collaborate across governments, cultures, and scientific disciplines. His international work has since expanded throughout the Middle East, France, and French-speaking African nations, supported by his fluency in Arabic and conversational proficiency in French.
After an accomplished government career, Nader transitioned into executive leadership within the private sector, bringing invaluable agency insight to some of the world’s leading agricultural, consumer products, and animal health organizations. His leadership roles with SC Johnson, Perrigo Animal Health, Merial (Sanofi), Elanco, PetIQ, and Nufarm allowed him to shape regulatory strategy across North America while overseeing EPA and FDA submissions, pesticide registrations, animal health approvals, product lifecycle management, post-approval compliance, and cross-functional business initiatives. In each role, he successfully bridged scientific excellence with commercial objectives, helping organizations accelerate innovation while maintaining the highest standards of regulatory integrity.
Throughout his executive career, Nader has become widely respected for his ability to translate complex scientific and regulatory requirements into practical business strategies. His expertise includes pesticide regulation, animal health regulatory affairs, toxicology, environmental science, microbiology, entomology, regulatory policy, environmental compliance, risk assessment, project management, and leadership development. Having worked from both sides of the regulatory process—as both regulator and industry executive—he understands how to anticipate regulatory challenges, develop proactive strategies, and build productive relationships with government agencies while advancing organizational goals.
Equally impressive is Nader’s leadership style, which emphasizes collaboration, mentorship, and mutual respect. He has successfully managed multidisciplinary teams, mentored regulatory professionals, negotiated with federal agencies, and worked alongside research, legal, manufacturing, commercial, and executive leadership teams to achieve common objectives. His ability to foster trust across organizations has consistently strengthened operational performance while creating cultures focused on accountability, scientific excellence, and continuous improvement. His guiding belief that “everyone matters” is reflected not only in how he leads teams but also in how he approaches partnerships, negotiations, and organizational development.
Nader has also remained active as a presenter and industry contributor, sharing his expertise on regulatory affairs, environmental policy, pesticide science, and animal health compliance. His ability to communicate highly technical information in a clear, practical manner has earned him recognition as both an educator and strategic advisor. Whether speaking before professional audiences or collaborating with executive leadership teams, he consistently demonstrates an ability to simplify complexity and facilitate informed decision-making.
Today, Nader is actively pursuing opportunities to serve on corporate and advisory boards where his unique blend of academic research, federal regulatory leadership, and executive industry experience can provide meaningful strategic value. He believes that organizations benefit most when scientific integrity, sound governance, and effective communication are aligned with long-term business objectives. His comprehensive understanding of academia, government, and private enterprise positions him to help boards navigate regulatory complexity, enterprise risk, innovation, sustainability, and organizational growth with confidence.
Outside of his professional accomplishments, Nader enjoys traveling, following soccer, and building relationships with people from diverse cultures and backgrounds. His international experiences have reinforced his appreciation for collaboration, respect, and lifelong learning. Guided by his personal philosophy—“Respect all people, everyone matters, and if you have good communication skills it will take you far”—he continues to lead with humility, integrity, and a genuine desire to make a lasting difference through thoughtful leadership and service.
