Alumni Stories
  • A perfect bunker at Deerfield Golf Club

    Behind the greens

    April 06, 2026 | Written by Molly Schafer
    Before the pros tee off at the 2026 Masters Tournament or amateurs take their first swing on their local links, an entire industry lays the groundwork for the perfect golf course. Alumni, faculty, and students in the College of Agriculture and Natural Resources rely heavily on science and technology as they work behind the scenes on the green.
  • The adventure continues

    February 27, 2026 | Written by Molly Schafer | Photos courtesy of Jennifer Reith, Erika Mathews, Erin Curry and Tiffany Carro | Photo illustration by Molly Schafer
    In 2003, four adventurous animal science majors embarked on a University of Delaware study abroad program in New Zealand. The Blue Hens toured sheep farms, hiked glaciers, and became lifelong friends. After the course, Erika (Feierstein) Mathews, Erin Curry, Tiffany Carro and Jennifer (Cascarino) Reith developed a serious case of wanderlust. The friends decided to travel regularly, and 23 years later, they are still exploring the world together.
  • Growing resilience

    February 17, 2026 | Written by Molly Schafer | Photos courtesy of Carol Long
    This year, Winterthur celebrates its 75th anniversary; the estate was incorporated as a museum in 1951. The 60 acres of wild gardens were created in the early 1900s by horticulturist Henry Francis du Pont. Distinguished alumna Carol Long is the garden manager at Winterthur, where portions of the grounds are home to some of the oldest trees in Delaware. Long discusses the changes in the natural world she has observed throughout her 34-year career.

2026 Winner

A. Joseph Cornelius, Ph.D.

CEO

Gates Agricultural Innovations

A. Joseph Cornelius, Ph.D., has spent a lifetime advancing a simple but powerful idea: that science and innovation can transform lives. As Chief Executive Officer of Gates Agricultural Innovations (Gates Ag One), he leads efforts to deliver cutting-edge agricultural solutions to smallholder farmers across Sub-Saharan Africa and South Asia—helping strengthen food systems, improve nutrition, and expand opportunity where it is needed most. 

A proud graduate of the University of Delaware’s College of Agriculture and Natural Resources in 1975 with a bachelor’s degree in Plant Science, Dr. Cornelius began his journey with a deep curiosity about how science could serve society. Over the past four decades, that curiosity has grown into global impact. He has led the discovery, development, and deployment of more than 50 agricultural innovations and startup enterprises across six continents, reaching more than 500 million farms and contributing to meaningful gains in productivity, farmer livelihoods, and environmental sustainability. 

His career has spanned the frontiers of science, policy, and industry. Prior to Gates Ag One, he served as a Director at the U.S. Department of Energy’s Advanced Research Projects Agency–Energy (ARPA-E), where he advanced breakthrough technologies at the intersection of agriculture, energy, and climate. He has also held senior leadership roles across the global life sciences industry, shaping large-scale research and development efforts and long-term innovation strategies. 

Yet, for Dr. Cornelius, impact extends beyond technology. A former UD student-athlete, he remains committed to mentorship, community engagement, and fostering the next generation of leaders dedicated to using science to serve society.

He shares this journey with his wife, Dr. Lynn Cornelius, a fellow University of Delaware graduate (UD ’77), Professor and Division Chief of Dermatology at Washington University School of Medicine, and leader of the melanoma multidisciplinary initiative at the Siteman Cancer Center. Together, they exemplify a shared commitment to advancing knowledge, improving lives, and giving back.

Dr. Tiffany Carro

Distinguished Alumni Award Recipient

UD Degree: Animal Science, '07M

Current Role: Head of Global Regulatory Affairs, Sciences and Strategy at FMC Corporation

Dr. Tiffany Carro leads the Global Regulatory Affairs, Sciences and Strategy department within the Research and Development organization at FMC Corporation, an agricultural sciences company whose mission is to advance farming through innovative and sustainable crop protection technologies.

Originally from New York, Tiffany’s first real exposure to agriculture occurred at the University of Delaware while pursuing an undergraduate degree, where she developed a passion for research and lab work that focused on safety consciousness for our environment.

A trained environmental toxicologist, Tiffany has held research roles in the pharmaceutical industry and remediation programs within the U.S. Fish and Wildlife Services Superfund initiative. In 2012, she joined DuPont Crop Protection as a regulatory environmental toxicologist, supporting innovation and life cycle management programs as a subject matter expert. In her current role at FMC, she leads global regulatory strategy for crop protection, ensuring science-driven innovation reaches growers around the world. Tiffany represents her company at CropLife International and serves on the external advisory board for the Delaware Environmental Institute (DENIN).

Tiffany graduated from the University of Delaware with a B.S. double major in animal science and agricultural education in 2004, and her M.S. in animal science in 2007. She earned her Ph.D. from the University of Maryland in 2012, where she studied avian toxicology. Tiffany now resides in Maryland with her husband and their two children.

Theodore Henry Carski, Ph.D.

Distinguished Alumni Award Recipient

UD Degree: Soil Chemistry, '86PhD

Current Role: Retired from DuPont Ag Products and DuPont Crop Protection (32 years)

Ted Carski retired after 32 wonderful years with DuPont Ag Products and DuPont Crop Protection. The thriving work environment with very gifted scientists was collaboratively focused on discovering and bringing to market innovative crop protection products. Ted helped investigate and integrate crop protection products’ fate in the environment into the discovery, development and stewardship of the products. Ted’s career began in laboratory research. His later roles included Research Fellow, Six Sigma Black Belt, R&D Project Manager, and Global Registration Portfolio Leader.

Ted’s post-retirement efforts and resources have been spent on promoting healthier local watersheds, especially through ShoreRivers Inc., which protects Maryland’s Eastern Shore waterways through science-based advocacy, education, engagement, and restoration. Roles include Governing Board, Ag Committee, Watershed Advisory Board, as well as bacteria and submerged aquatic vegetation and water quality monitoring programs.

Ted and his wife, Janet, live, boat, kayak, fish and hunt on the Eastern Shore and want to contribute to restoring and maintaining the health of this special watershed. ShoreRivers offers the perfect opportunity to put their resources and experiences to work, ensuring sound science informs decision-making, to improve the health of Eastern Shore rivers and creeks, and ultimately the Chesapeake Bay.

Ted keeps the University of Delaware close with continued support of CANR and the Delaware Environmental Institute (DENIN), previously serving on the External Advisory Boards for both, sponsoring the UD summer internship program with ShoreRivers, a DENIN graduate Fellowship, and the CANR Donald L. Sparks lectureship series.

Ted holds a doctorate in soil chemistry from the University of Delaware, graduating in 1986. He also holds a master’s in agronomy from the University of Maryland and a bachelor of science in chemistry from Loyola College.

Ms. Jacqueline Cascio

Distinguished Alumni Award Recipient

UD Degree: Food & Agribusiness Management, '01

Current Role: Vice President of Sales Grocery Speciality at Perdue Farms

Jackie Cascio likes to say she has chicken running through her veins. Her grandfather owned Wadman’s Poultry in Connecticut and was one of Perdue Farms’ first customers. Her father, Jack, then took over the family business. Jackie spent days alongside her dad, sitting in the trucks to deliver chicken to customers or doing bookwork.

Jackie has been with Perdue Farms for close to 25 years. One week after graduating from the University of Delaware College of Agriculture and Natural Resources in 2001 with a B.S. in Food and Agribusiness Management, she moved to Salisbury, Maryland, to start her career with Perdue in the customer service department. After a few years of learning the basics of retail sales, she was given the opportunity to move into outside sales, first calling on smaller accounts in Pennsylvania. If you were to ask her younger self, Jackie never imagined a career in sales. Her career grew in responsibility, calling on larger accounts and managing teams.

As part of her development, she moved into a corporate Trade Marketing Role, allowing her to understand more parts of the business while gaining a deeper understanding of the decision-making process and the "whys". While the role provided valuable insight, Jackie’s passion for sales — particularly customer relationships and business growth — ultimately led her back to the commercial side of the business.

Today, Jackie serves as Vice President of Grocery Specialty Sales, leading a high-performing team that manages strategic accounts such as Aldi, Butcher Box, Dollar General, Sprouts, Trader Joe’s and Whole Foods. Her keys to success: Strong relationships at every level, building trust through transparency, embracing change, and having a people-first leadership mindset.

Dr. Danielle Diamond

Distinguished Alumni Award Recipient

UD Degree: Animal Science, '05

Current Role: Associate veterinarian at the Veterinary Urgent Care Center in Narragansett and the Veterinary Emergency Group in Warwick, Rhode Island

Dr. Danielle Diamond's lifelong journey in service began as a "Navy brat" traveling the world, a tradition she proudly continued by entering the United States Army Veterinary Corps. A graduate of the University of Delaware College of Agriculture and Natural Resources (Major: Animal Science/Concentration in Pre-Veterinary Medicine, Minors: Biology and Wildlife Conservation & Biology, 2005 ) and the Tufts University Cummings School of Veterinary Medicine (Doctor of Veterinary Medicine, 2009), Dr. Diamond recently expanded her expertise by completing a Master's in Veterinary Forensics through the University of Florida.

Over 14 years of active duty, Dr. Diamond served in domestic and international posts, including deployments to Djibouti and Qatar. Following a prestigious Small Animal Surgery residency at North Carolina State University, she transitioned to civilian practice while continuing her military service as a Reservist. She currently serves as the Commander of the 169th Medical Detachment Veterinary Services at Fort Eisenhower, Georgia.

In her civilian career, Dr. Diamond provides surgical and critical care as an associate veterinarian at the Veterinary Urgent Care Center in Narragansett and the Veterinary Emergency Group in Warwick, Rhode Island. She remains deeply involved in specialized medicine, frequently assisting the Massachusetts State Police Working Dogs through the newly established Tufts New England Working Dog Center of Clinical Excellence. From providing international veterinary aid in Cotacachi, Ecuador, to treating beloved local pets at "Camp Couch," Dr. Diamond is dedicated to ensuring every animal lives their healthiest life.

Dr. Diamond's distinguished military career is marked by numerous honors, including two Meritorious Service Medals and the Joint Service Commendation Medal. When she is away from the clinic or the command, she is an avid amateur equestrian, a fly fishing enthusiast, and a devoted "auntie" to her nephews and her beloved Labradors.

UD Degree: Entomology, '00

Current Role: Assistant Professor in the Department of Microbiology, Immunology, and Pathology at Colorado State University

Dr. Rebekah Kading is an Assistant Professor in the Department of Microbiology, Immunology, and Pathology at Colorado State University. Rebekah obtained her B.S. in Entomology with a concentration in Wildlife Conservation from the University of Delaware in 2000.

While at UD, Rebekah conducted undergraduate research on the wood thrush with Dr. Roland Roth and nurtured her growing interest in mosquitoes and vector-borne diseases. She worked as a seasonal employee for two summers for the Mosquito Control Section of the Delaware Department of Natural Resources and Environmental Control. The job led her to appreciate the global significance of mosquito-borne diseases and One Health (interconnected human-animal-environmental health).

She went on to obtain her M.S. in Entomology from the University of Arkansas and Ph.D. from the Johns Hopkins Bloomberg School of Public Health. Her Ph.D. research focused on malaria transmission dynamics in southern Zambia and ignited a passion for work that would have a positive health impact in Africa. Following graduation, Rebekah worked for the U.S. Centers for Disease Control and Prevention Arbovirus Diseases Branch, where she led studies on mosquito blood-feeding behavior and West Nile virus ecology in Colorado and Guatemala, Rift Valley fever virus transmission by mosquitoes, and bat-associated viruses in Uganda.

Currently, Dr. Kading's diverse research program at Colorado State University continues to have a significant global footprint in studying the ecology and transmission of vector-borne and zoonotic viruses within a One Health framework. Her research spans the viral ecology of bats in Uganda, the arbovirus ecology in Myanmar, and the Rift Valley fever virus in Tanzania. She founded Musoke International in 2016, a charity that supports the education of orphaned children in Uganda. Rebekah plays the violin and is a proud mom to sons Jonah, Jasper, and Jett.
