Johanna Holman, B.S.

Master’s of Science, Human Nutrition and Food Sciences

Johanna joined the lab in fall 2020 to investigate the effects of diet on the gut microbiome, and on host-microbial interactions. For the past several years, she has been working with researchers at Husson University, and her project will combine her previous work on the nutritional biochemistry of broccoli with effects on gut microbes.

Sarah Hosler, B.S.

Master’s of Science, Animal Science

Sarah is from Newton, NJ and has lived in NJ her whole life until she started college at Albright College in PN. Her undergraduate research was on protein classification. Sarah joined the lab in fall 2020 to create new methods for studying host-microbial interactions.

“I am excited to see how much I grow through my graduate experience at the University of Maine. I’m also a little bit nervous about the cold, but I’m sure I will get used to it.”

Jade Chin

Undergraduate Researcher, Animal and Veterinary Sciences, Biology

Jade is an Animal and Veterinary Sciences major with a pre-veterinary concentration, originally from Connecticut. She joined the lab in summer 2020 to study leaf silage microbes for her Honors thesis. She plans to study abroad at the University of Glasgow during her senior year and attend their veterinary school after her undergraduate degree.

Undergraduate Researcher, Ecology and Environmental Sciences

Nick is exploring the microbial communities associated with wild Maine blueberry soils in a joint project between Drs. Lily Calderwood and Ishaq.


Grace Lee

Undergraduate Researcher, Neuroscience, Bowdoin College

Grace was accepted to the University of Maine REU program for summer 2020, which was postponed due to pandemic concerns. She’ll joined the Ishaq lab remotely to learn data analysis for a project on microbes and animal health. She hopes to continue her love for science and service in a future career in the medical field as a clinical physician. Her passions outside of school work include playing the viola and spreading awareness of different ethnic backgrounds and cultures.

Undergraduate researcher, Animal and Veterinary Sciences

Emily is an Animal and Veterinary Sciences major with a concentration in pre-veterinary medicine and a minor in microbiology from central Vermont. She joined the lab in spring 2020 to study work on culturing rumen cells and the immune factor production after coculturing with microbes. After finishing her undergraduate degree, she will be attending school for Veterinary Medicine.

Adwoa Dankwa, M.S.

Doctorate of Philosophy

Adwoa Dankwa

Human Nutrition and Food Sciences, Adviser: Dr. Jen Perry

Adwoa is a graduate student in Food Science and Human Nutrition department. Adwoa’s work in the Perry lab is focused on understanding the microbial and chemical composition of fermented non-dairy low alcohol beverages and how these influence consumer acceptability over time. Dr. Ishaq serves on Adwoa’s committee to provide expert advice on microbial ecology, DNA sequencing, and bioinformatic analysis. Aside from formal mentorship, Dr. Ishaq provides insight, support, and encouragement in all areas that are deemed helpful in making Adwoa succeed in her program. Adwoa originally hails from Ghana and is loving all the seasons Maine has to offer.


Marjorie Killerby, B.S.

Master’s of Science

Animal Science, Adviser: Juan Romero

Marjorie is a Bachelor in Veterinary Medicine originally from Lima, Peru and is currently studying to earn a Masters in Animal Science in the University of Maine, Orono. She is researching the effects of novel preservatives on nutritional quality and microbial communities in silage and hay for the dairy industry. I am mentoring Marjorie as a graduate committee member in microbial ecology, DNA sequencing, and bioinformatic analysis.


Tindall Ouverson, B.S.

Master’s of Science

Land Resources and Environmental Sciences, Montana State University. Adviser: Dr. Fabian Menalled and Dr. Tim Seipel

Tindall graduated in May 2018 with a B.S. in Sustainability Science, summa cum laude, from Furman University in Greenville, SC. Currently, she is conducting research in the Weed and Invasive Plant Ecology and Management Group with Drs. Fabian Menalled and Tim Seipel. Specifically, her research focuses on the response of soil microbial communities to cropping systems and climate change in semiarid agriculture. I am mentoring Tindall as a graduate committee member in microbial ecology, DNA sequencing, and bioinformatic analysis.
