Principal Investigator:

Dr. Anup Kollanoor Johny BVScAH, MVSc, PhD

Associate Professor

Anup JohnyDr. Johny joined the department in December 2013 as an Assistant Professor – tenure track after completing his postdoctoral research/teaching training at the University of Connecticut. He has a doctorate in Animal Science from the University of Connecticut, Masters in Veterinary Science (in Animal Nutrition), and Bachelors in Veterinary Medicine (DVM equivalent) from the Kerala Agricultural University, India. His research interests broadly include alternative approaches to improving animal performance, reducing/inactivating zoonotic (multidrug-resistant) pathogens, pre-and post-harvest food safety, antibiotic resistance mitigation, and the use of Omics technology to understand colonization and survival strategies in animal pathogens and beneficial microorganisms. He has been consistently contributing to the applied and molecular research on using phytobiotic nutrition as an intervention strategy to control Salmonella, Campylobacter, Listeria, and Clostridium in poultry.

Dr. Johny’s initial training as a veterinarian gives him a broad perspective in working with live animals for improving production and health. His master’s training in applied poultry (phytase, trace minerals, and algae) nutrition has strengthened his research skills in controlled broiler and layer experiments for improving growth performance, mineral balance, and meat quality. For his doctoral studies, Dr. Johny was trained in challenge experiments in broilers and layers and has developed models of Salmonella mitigation as it relates to food safety. He was also trained in in vitro screening of antimicrobials against pathogens, cell culture, gene expression assays, and microarray technique, and has developed skills on microbial transcriptomics during his postdoctoral training. Currently, he works with his lab group on several projects targeted to control foodborne pathogens and alleviate antimicrobial resistance in animal production using in vivo challenge models and omics technology. In addition, he focuses on the post-harvest microbiological safety of poultry products, including eggs.


Research Associate:

Dr. Luna Akhtar Ph.D.

lunaDr. Luna Akhtar is a food safety microbiologist. She earned her MSc in Parasitology and M. Phil in Microbiology from the University of Dhaka, Bangladesh. She has a Ph.D. from Kansas State University. The focus of Dr. Akhtar’s research is investigating the interplay between foodborne pathogens, including Salmonella, Listeria, and Shiga toxigenic E. coli, and the commonly used antibacterials. Her research also covers the therapeutic evaluation of antibacterials in animal models of pathogens. Currently, Dr. Akhtar is working with Dr. Johny in his alternatives to antibiotics research targeting the control of MDR Salmonella Heidelberg and evaluate their potential in turkey and broiler challenge models. Dr. Akhtar has been also serving as a Microbiology Faculty at NHCC, a Minnesota State College, and teaches Microbiology and Medical Terminology courses. She also likes to contribute to the University and Community by serving on non-academic committees.


Graduate Research/Teaching Assistants:

Ms. Grace Dewi BS, MS – ANSC Ph.D. program
2019-2020 MnDRIVE Fellow
2016-2018 Rising Scholar ANSC

GraceDGrace was born and raised in Jakarta, Indonesia’s capital. She first moved to the United States in 2013 to attend the University of Minnesota, where she obtained her Bachelor’s degree in Animal Science. During her senior year, she volunteered in Dr. Anup Kollanoor Johny’s lab and became interested in microbiology and food safety. She successfully defended her M.S. thesis in the fall of 2018. She is currently pursuing her doctoral degree in Animal Science and is advised by Dr. Johny. Her research focuses on the antibacterial properties of plant-derived products against foodborne pathogens in poultry. Specifically, she is investigating the efficacy of essential oils against Salmonella colonization factors. Beyond her academic activities, she enjoys spending time with family and friends, drawing, and occasionally playing badminton and video games.

Ms. Claire Peichel BS, MS – ANSC Ph.D. program
2017-2020 USDA National Needs Fellow
2020 MnDRIVE Fellow


Claire is a first-year doctoral student in Dr. Johny’s lab. She joined Dr. Johny’s laboratory as an NNF fellow for her MS program and successfully defended her research thesis. She attended the University of Minnesota for Food Science where she became interested in Food Safety and Microbiology. Claire joined Dr. Johny’s lab in her sophomore year and has continued to expand her research while pursuing her Master’s degree. Claire has been a member of the Food Science and Nutrition Club and the Gopher Poultry Science Club. In her free time, Claire likes to hang out with friends, read books, and hike.

Ms. Shijina Manjankattil BVScAH, MS – ANSC Ph.D. program
2020 MnDRIVE Fellow

Shijina Raj Manjankattil Rajan-2017 (1) (1)Shijina Raj is a master’s student in the lab. Her current research focuses on the alternative to antibiotics in poultry production. Shijina has a bachelor’s degree (DVM equivalent) from Kerala Veterinary & Animal Sciences University (KVASU), India. After her DVM program, she completed a certificate course on ‘One Health’ from KVASU. Then she served as a research assistant in the poultry and duck farm at KVASU and got acquainted with poultry management practices and processing technology. She enjoys reading stories and practicing yoga in leisure time.
