Karuna Kharel
Ph.D. Student
Karuna earned her MS degree in Food Science and Technology from the Louisiana State University. Her Master’s research focus was on ensuring pre- and post-harvest safety of treenuts where she developed post-harvest thermal intervention strategies to destroy bacterial pathogens on Pecans. Her research also answers several critical questions related to quality changes and consumer acceptability resulting from thermal treatments. Currently, her research focus is on thermal intervention strategies on produce and several other nuts. She is also involved in other research projects focusing on fresh produce and sprout safety. In addition to her academic research, she is an active participant of several volunteer activities and leadership roles in LSU and the Baton Rouge.
