2021 Maiben Lecturer

Dennis Ferraro

Dennis is the resident herpetologist and a professor of practice at the School of Natural Resources at the University of Nebraska-Lincoln. He has been a UNL faculty member since 1990. "My main goal in my career and in life is the conservation of amphibians, reptiles and turtles in North America," he said. Dennis maintains the university's live animal lab of native Herpetofauna for research and educational purposes, and has developed a health and medical protocol for the animals' care. Underlying the many projects that Dennis has in the works are his ongoing goals: to promote the conservation of Nebraska's amphibians and reptiles to the public, and to instill appreciation of and stewardship for natural resources in students and youth.

2020 Honorees

Tiffany Heng-Moss

Dr. Tiffany Heng-Moss currently serves as Dean for the College of Agricultural Sciences and Natural Resources (CASNR).  Since joining the University of Nebraska-Lincoln (UNL) faculty in 2001, Dr. Heng-Moss has developed and taught both undergraduate and graduate courses along with providing leadership for the development and implementation of multiple academic degree programs in the College of Agricultural Sciences and Natural Resources. She is passionate about teaching; focuses on student success; is excited about agriculture and science; and motivates students to want to learn.

Dr. Heng-Moss currently provides leadership for NebraskaSCIENCE, which is a partnership initiative among the Colleges of Arts and Sciences, Education and Human Sciences, and Agricultural Sciences and Natural Resources; contributes to the Institute of Agriculture and Natural Resources’ (IANR) science literacy program that is focused on providing education platforms for the continuum of learners in resilient food, energy, water and societal systems; has facilitated the development of the undergraduate Life Sciences curriculum at the University of Nebraska-Lincoln; and has partnered with Nebraska schools to offer food, energy, and water systems experiential learning opportunities to K-12 students and educators.   

In her role as dean, Heng-Moss has led the development of the college’s graduate education framework, college-level attributes, a smart enrollment growth framework, and the first education compact in Nebraska. She has authored/co-authored over 85 refereed teaching and research articles and secured over $50 million in teaching/outreach grants and $9 million in research funds.

Heng-Moss has received several teaching awards, including the USDA National Award for Excellence in College and University Teaching in the Food and Agricultural Sciences, the Entomological Society of America Distinguished Achievement Award, Gamma Sigma Delta Teaching Award, and the University of Nebraska Outstanding Teaching and Instructional Creativity Award (OTICA).

David Harwood

Dr. David Harwood is a Professor and TM and EE Stout Chair of Stratigraphy in the Department of Earth and Atmospheric Sciences (EAS) at the University of Nebraska-Lincoln, and has been in service there since 1989. He graduated with a Ph.D. in Geology and Mineralogy in 1986 from The Ohio State University, a M.S. in Geology in 1982 from Florida State University, and a B.S. in Geology in 1980 from the University of Akron.  Harwood’s main research interests involve reconstructing the paleoenvironmental and paleoclimatic history of Antarctica and the Southern Ocean through paleontological and stratigraphic studies of sedimentary rock sequences and drill cores. His specific expertise is as a micropaleontologist and stratigrapher, studying Cretaceous and Cenozoic diatom microfossils and applying them in biostratigraphy and paleoecology. He has been to Antarctica and the Southern Ocean 18 times, leading small tent-based remote field teams, as well as large international drilling projects like the Antarctic Geological Drilling Program (ANDRILL), of which he was the U.S. Principal Investigator. He now manages the Hot Water Drilling Program at UNL, which drilled more than 1000 meters below the West Antarctic Ice Sheet in 2018 to provide access into Mercer Subglacial Lake. Dr. Harwood teaches a general education course entitled ‘Frontiers in Antarctic Geosciences’, as well as courses in ‘Micropaleontology’ and ‘Siliceous Phytoplankton Paleontology’. Since 2004, Harwood has led an impactful summer professional development experience for science teachers in conjunction with NMSSI, a 16-day inquiry-based geoscience field course across WY, NE, SD, where teachers discovery the history of the Rocky Mountains and sharpen their classroom skills. Harwood has been the recipient of numerous awards in recognition of his commitment to science and education in Nebraska including: Catalyst Award from the Nebraska Association of Teachers of Science (2015); Distinguished Teaching Award, College of Arts & Sciences (CAS), UNL (2019); Lawson Award Dept. EAS, UNL (2015) and Coffman Excellence in Geology Award from EAS, UNL, was recognized as a NSF Presidential Young Investigator (1991-1996), and is presently a Dean’s Fellow of the College of Arts & Sciences Teaching Academy, UNL.
