Joanna Chiu: From Scholar to Professor to Department Chair

Scholar, teacher, mentor, researcher, author, collaborator, leader, optimist and administrator.

Those are some of the roles of Professor Joanna Chiu, molecular geneticist and physiologist, who advanced from vice chair to chair of the UC Davis Department of Entomology and Nematology on July 1. She is serving a five-year appointment, succeeding nematologist Steve Nadler, the chair since Jan. 1, 2016.

As Dean Helene Dillard of the UC Davis College of Agricultural and Environmental Sciences said today: "I am pleased Joanna Chiu has been appointed as the chair of the Department of Entomology and Nematology. She is an outstanding scholar and teacher with demonstrated leadership skills.  I look forward to watching Professor Chiu thrive in her new role as chair and seeing the department continue to flourish.”

Chiu joined the Department of Entomology and Nematology in 2010 as an assistant professor, and advanced to associate professor and vice chair in 2016, and to professor and vice chair in 2021. She was named one of 10 UC Davis Chancellor's Fellows in 2019, a five-year honor awarded to associate professors who excel in research and teaching. The UC Davis Academic Senate honored her with a Distinguished Teaching Award, Graduate/Professional category, in 2022. She most recently received the Chancellor's Award for Excellence in Mentoring Undergraduate Research.

Chiu co-founded and co-directs (with professors Jay Rosenheim and Louie Yang) the campuswide Research Scholars Program in Insect Biology, launched in 2011 to provide undergraduates with a closely mentored research experience in biology. The program's goal is to provide academically strong and highly motivated undergraduates with a multi-year research experience that cultivates skills that will prepare them for a career in biological research.

A native of Hong Kong and a first-generation college student, Joanna received her bachelor's degree, magna cum laude, in biology and music from Mount Holyoke College, Mass., and her doctorate in molecular genetics in 2004 from New York University, New York. She trained as a postdoctoral fellow from 2004 to 2010 in molecular chronobiology at the Center for Advanced Biotechnology and Medicine, at Rutgers, the State University of New Jersey.  Her postdoctoral training was funded by an NIH F32 Ruth L. Kirschstein National Research Service Award postdoctoral fellowship and K99/R00 Pathway to Independence Award.

"I grew up not knowing any scientists,” she related. “Both my parents work in the financial industry and neither went to college. However, my dad loves the outdoors and my childhood memories includes snorkeling with my dad and siblings, hiking in the very limited outdoors in my native Hong Kong, and watching a lot of National Geographic on TV. As a result, I have always been curious about biology, especially animal behavior.  I really hoped to study biology in college. My parents, on the other hand, wanted me to be a doctor."

“I certainly have never ever dreamed of being a professor when I was a college student. I just know I love biological research so I can learn more about the natural world, I love asking questions, and I love the joy of discovery."

Her students offer high praise.

In nominating Chiu for the Chancellor's Award for Excellence in Mentoring Undergraduate Research, then doctoral Christine Tabuloc (now a PhD) wrote: "I joined Dr. Chiu's laboratory at the beginning of my second year here at UC Davis and remained a member of the lab for 3 years as an undergraduate, 2 years as a technician, and 6 years as a graduate student."

"Dr. Chiu welcomed me into her lab back in 2012," Tabuloc noted. "I had just finished my first year of college, and I had virtually no research experience. Despite this, Joanna took a chance on me and invited me to join her lab. Throughout the years, Joanna has taught me many skills—both at the bench and skills that translate outside the lab and even beyond academia. Joanna has taught me everything I know from performing an experiment with all the proper controls to mentoring students and giving effective and clear presentations. What makes her so outstanding is her commitment to helping us improve as scientists and researchers and preparing us for our future career endeavors."

"Not only have I experienced Dr. Chiu's mentorship first-hand, but I have also had the privilege of watching her mentor all the undergraduate students that have joined her lab throughout the years. In fact, since my time here, I have watched at least 35 undergraduates be mentored by Joanna, and many of these students were authors on publications in peer-reviewed journals such as Scientific Reports, Journal of Pest Science, BMC, Ecology, Current Biology, Nature Communications, Journal of Economic Entomology,and PLOS Genetics. More so, a true testament to her success as an undergraduate mentor are her students' successes: furthering their education at academic institutions such as Cornell, Stanford, Columbia, UCB, and UCLA or landing industry jobs at companies such as 10X Genomics. Many of these students still keep in contact with Dr. Chiu, and she continues to provide advice and guidance such as reviewing resumes and helping them prepare for interviews. Joanna is not just our mentor when we are at UCD, she is our mentor for life."

Other comments in the nomination awards packet echo Tabuloc's words:

  • "As a PhD student at Cornell, I am immensely grateful for the training I received as an undergrad from Dr. Chiu. Not only did she train me thoroughly in basic biochemistry and molecular biology techniques, but she also pushed me to be independent and think critically about my science, skills essential for graduate school."--Jessica West

  • "Beyond teaching me practical research skills, Dr. Chiu helped to spark the most important thing a person needs to be a successful scientist: pure joy in the pursuit of knowledge."--Katie Freitas

Joanna Chiu: scholar, teacher, mentor, researcher, author, collaborator, leader, optimist and administrator. But we should add at least one other attribute: "dog lover."

"Outside of my research and my job, I really enjoy spending time with my dogs (Oliver and Kaia are Golden Retrievers and Phoebe is a Nova Scotia Duck Tolling Retriever)," she recently told us. "We do conformation, scentwork, obedience, dock diving, retriever training, and are starting to train in agility."

Chiu takes the departmental helm with two outstanding scientists, both community ecologists: Rachel Vannette, associate professor, the new vice chair, and Louie Yang, professor, the new Entomology Graduate Program chair. 

Chiu has held both positions.
