Dr. Feng

Headshot with scarf 2018

Dr. Feng is an assistant professor of food science at Purdue University. Feng’s research program explores cultural, social, and environmental factors that affect food safety behaviors. The goal of Dr. Feng’s research program is to identify barriers to understanding food safety issues and evaluate strategies that empower stakeholders to make science-based decisions. By using both qualitative and quantitative research methods and working with farmers, food workers, and consumers, Dr. Feng’s work can increase the knowledge of different sectors of the food supply chain: which include consumers, food processors, retailers and the policymakers.


PhD Students



Tressie received a B.S. in Biological Engineering from Purdue University and is currently pursuing her PhD in Food Science.  She works on projects related to food safety education for youth ages K-12.  Currently, Tressie is developing high school curriculum that can be used in the classroom to improve student food safety knowledge and food handling practices.  Tressie also works on evaluating food safety messages delivered on web-based platforms.

Merlyn received her master’s in food science  from the University of Georgia and is pursuing her PhD in Dr. Feng’s lab studying the social implications of  food safety. She has assisted in projects related to pet food safety and food handling practices of university students. Currently, she is working on projects related to food safety and the COVID-19 pandemic. She hopes to learn and grow during her time at Purdue and in the Feng Lab.


Master Students



My name is Han and I'm currently a graduate student in Dr. Feng’s lab. Currently, I'm working on the veteran farmer project, which is to evaluate the attitude, knowledge, and practices of veteran farmers. Previously, we found out that there was little research conducted to understand the barriers faced by veteran farmers who may struggle to balance profits and the increasing food safety regulatory requirements. Therefore, we want to identify the major barriers and develop a better food safety education program for veteran farmers.



Undergraduate Students



My name is Leah and I am a sophomore undergraduate student studying public health. I am conducting video reviews for the observational study conducted at Salem High School.





My name is Carley and I am a senior studying animal sciences with a focus on production animals. My main focus in Dr. Feng’s lab is creating content for the web page. Last year I helped create a web page for the lab and have been in charge of running it ever since. I have also been put in charge of creating and maintaining the lab's Twitter page. My additional jobs in the lab include creating flyers and educational material for the lab and lab members to use.

My name is Ishani and I am currently a freshman food science major at Purdue. My role in the lab is to help Dr. Feng with various research projects. I’ve mainly worked on identifying, extracting and analyzing data from published research to enable meta-analyses of key factors in food safety practices and processes. I’m very excited to be starting out my freshman year in Dr. Feng’s lab!





I am a sophomore majoring in Food Science with a minor in Nutrition. I'm currently working with Han Chen on the veteran farmer's project transcribing previous veteran farmer focus groups.



Ziyue Zhang

Ziyue is a Junior majoring in Food Science. She is an undergraduate research assistant in the lab. Currently, she is helping Dr.Feng do the on-line survey project on pet food safety.




I am a sophomore double majoring in Food Science and Biological Engineering with a concentration in food and bioprocessing. As an undergraduate research assistant, I help collect food handling data from various video recipes. I also assist with a food safety workshop geared towards individuals of low socioeconomic backgrounds.




My name is Cai Chen and I am a freshman at Purdue majoring in agribuisness. I'm currently working with Han on the veteran farmer project. I code literature reviews, transcribe focus groups, and assist Han in carrying out focus groups.
