2025

Microbes and Mayhem

Lily, Kate, and Oliver are selected for the URSA program

2/10/2025

Congrats folks for getting funded for OSU's Undergraduate Research Program. This years application was competitive.

Welcome Lily Zhen!

2/5/2025

Welcome Lily Zhen! Lily is an accelerated undergraduate / masters student with an interest in biomedical research. She will be co-advised by the Kloefkorn and Arnold labs working to characterize microbiome features which associate with osteoarthritis in a mouse model.

Welcome Kate Strange!

2/5/2025

Welcome Kate Strange to the Arnold and Jolles Labs. Kate is an undergraduate student majoring in biological data sciences. Her project will be working to characterize microbiomes in Desert Bighorn Sheep in the Grand Canyon. 

Welcome Oliver Lewis!

2/5/2025

Welcome Oliver as a new undergraduate student who will be co-mentored in the Kloefkorn lab - their project seeks to quantify behaviors within the mouse ethogram. Their goal is to ultimately identify microbiome features which associate with resilience to stress.

Emma is announced as a OSU Lenhard Graduate Fellow 2025

1/30/2025

This is a competitive award used to for graduate student support. Congratulations! 


2024

Lab init

Comparative microbiomes pilot is funded

10/25/2024

One Digital Health Coalition for Fight Against Non-Communicable Disease for 2024 Research Academy grant is awarded. This project will seek for microbial clades which are conserved across animal species in health which go missing during chronic enteropathies.

Arnold presents at Hill's Global Research Symposium!

10/25/2024

HK Arnold (2024) discussed The Microbiota-Gut-Brain Axis: How the Gut Microbiome May Shape (or Be Shaped by) Stress-Related Behaviors at Hill’s Global Symposium – Nourish the Gut, Nurture the Future. What a great opportunity to meet folks at this conference! 

Hill's Global Symposium Proceedings are released

10/23/2024

Arnold, HK. (2024). The microbiota-gut-brain axis: how the gut microbiome my shape (or be shaped) by stress related behaviors. Hill’s Global Symposium, Nourish the Gut, Nurture the Future.

Arman presents for CCVM Summer Research program

8/8/2024

Congrats Arman for giving an excellent presentation for the CCVM SURP program!

Microbiome x pain resilience project pilot is funded

8/1/2024

The goal of this grant is to understand how the microbiome is modulated in animals with somatic pain.

Welcome Amanda Majchrzak!

7/3/2024

Amanda will be a DVM PhD student where she will investigate how microbiome/virome associates in felines with and without stress-associated conditions. She is co-advised with the Beechler laboratory.

Arnold is named 2024 Research Advancement Academy Fellow

5/30/2024

The Research Advancement Academy is a professional development program for faculty across OSU to develop leadership skills to lead transdisciplinary research. Our project that was funded will seek microbes which are conserved in mammals with and without chronic intestinal disease disease. 

Congrats Arman Alavi

5/30/2024

Arman received funding to continue his project working to clarify how microbiomes differ in those with and without neurodegenerative disease for summer research this year. Thank you CCVM summer undergraduate research program.

Emma is announced as a OSU Lenhard Graduate Fellow 2024

5/30/2024

This is a competitive award used to for graduate student support. 

Welcome Emma Little

4/11/2024

Emma Little is joining the lab as a PhD student. She will investigate the microbiome's association to sea lion health in wild populations.She is co-advised with the Beechler laboratory.

Coming soon...

1/1/2024

The Arnold Lab opened its doors on 1/1/24 in the Department of Biomedical Sciences at Oregon State University. Hello world!


2023

Hello World!

Arman Alavi joins the lab

11/13/23

Arman Alavi is an undergraduate researcher in bioengineering. He will be working on a project to understand how the oral microbiome associates with the presence or absence of neurodegenerative disease.

Holly is accepted into OSU's Research Advancement Academy

10/05/23

Very honored to be a part of this group to develop research leadership skills. We are hoping to use this to spring board our One Health Institute at the Vet School.
