The Society of Nematologists (SON) will present him with its Teaching Excellence Award at its 55th annual meeting, set July 17 – 21 in the city of Montreal, Quebec, Canada.
Caswell-Chen, who joined the UC Davis Department of Nematology (now the Department of Entomology and Nematology) in 1989, was praised as being an “exemplary teacher who loves to teach and interact with his students.”
“Ed is known for his enthusiasm, dedication, high-quality instruction and keen interest in helping his students understand and appreciate nematology—from the undergraduate level to the graduate level and beyond,” his nominators said.
“If I had to distill my endorsement of Ed into a single sentence, it would be that he has unbridled passion and dedication when it comes to getting undergraduates excited about science,” said nematologist Steve Nadler, professor and chair of the Department of Entomology and Nematology. “His dedication to teaching is truly altruistic, and although he has maintained a solid program of research, his major effort in recent years has involved teaching undergraduate and graduate students.”
Over the last five years, Caswell-Chen has taught 24 undergraduate courses, enrolling some 2400 students. His commitment to teaching includes five years of service as associate dean of the Graduate Program, UC Office of Graduate Studies. He is a former chair of the UC Davis Department of Nematology, and the Graduate Group in Ecology.
Caswell-Chen, who considers teaching his No. 1 priority, says the classroom is “an important forum for communication with students, and an opportunity for outreach with respect to the Agricultural Experiment Station mission, especially when lecturing to undergraduates in nematology, animal biology, and science and society courses.” His students describe his courses as informative, interesting and engaging.
Caswell-Chen said his philosophy of teaching “is that to be effective, teaching must engage students by highlighting the relevance of course material, and instructors must capture student attention through enthusiasm and supportive stimulation of student creativity. Interaction helps students learn how to think, ask questions, and form connections among the diverse facts they learn in their courses.”
“If students are participating and engrossed with the topic in the classroom, they don't immediately realize that they are learning—they are carried along by their thinking and engagement with the material,” he said. “All of these features of effective classroom instruction are relatively easy to attain when the subject matter is nematology—and biology, for that matter—because of the field's many fascinating and relevant aspects. In a nematology course, one can incorporate a wide range of intriguing topics, from nematode biodiversity and the deep, hot biosphere to soil ecology, to the fascinating interactions between nematodes and other organisms, to the importance of animal parasites and means for their management, to plant parasites, nematicides, and genetic engineering of crop plants for nematode resistance, to topics in aging and neurobiology from research on the model nematode Caenorhabditis elegans.”
Caswell-Chen is known for his research on the life history and ecology of C. elegans, a free-living or non-parasitic nematode that lives in temperate soil environments.
His interest and dedication to undergraduate education is reflected in his current service as the chair of the UC Davis Academic Senate Undergraduate Council, membership on the UC system-wide Educational Policy Committee, and his recent appointment as vice chair of that same Educational Policy Committee for the coming academic year.
UC Davis researcher Kristi Sanchez, former undergraduate student who received her doctorate from him in 2014 and served as his teaching assistant, described him as “the best professor I've ever had.”
“I have not met another professor at UC Davis who not just focuses on his research but enjoys, loves and wants to make teaching classes a priority for undergraduate students,” Sanchez said. “He is always about the students and making sure they understand the material. He always goes out of his way to provide more office hours so they can learn the material better or ask questions. And he is a professor who has the students text him instead of emailing him. The students love it.”
She credited him with inspiring her to pursue her degree and career in nematology. “Ed has given me many opportunities to pursue research questions that I would like to investigate, provides great advice and not just as a major professor but a father figure. He has pushed me to follow my goals and with my hard work, anything is possible.”
Said graduate student Chris Pagan, who has known Caswell-Chen for 12 years, beginning as an undergraduate student and then as a lab technician: “Ed makes the classroom a comfortable place. He is always approachable, and always genuinely interested in hearing what students have to say. Ed is always revising his lecture material and methods. He is constantly seeking new ways to keep students engaged.”
Nematologist Becky Westerdahl, UC Davis professor of entomology and nematology, praised Caswell-Chen for his excellence in teaching and as “one of the first professors at UC Davis to embrace the use of World Wide Web technology for teaching…He was instrumental in obtaining, establishing and maintaining the first web server for teaching in the Department of Nematology.” She said Caswell-Chen provides his students with “an excellent foundation, not just as future researchers, but as future educators as well.”
Caswell-Chen also teaches animal biology courses and Science and Society courses. He sometimes teaches freshman seminars by using the Campus Book Project selections, such as “Why Are All the Black Kids Sitting Together in the Cafeteria” and “Half the Sky.” He has also taught his own selection of topics, including “The Ancient Middle East: Cradle of Civilization, Religion and Science” and “Protest Songs.”
Caswell-Chen received his bachelor's and master's degrees in botany and plant pathology from Michigan State University in 1979 and 1982, respectively, and his doctorate in 1985 in plant pathology from UC Riverside. He began his academic career in 1985 as an assistant professor in the University of Hawaii's Department of Plant Pathology before joining the UC Davis faculty in 1989.
