Comparative Medicine at Stanford Research Park Symposium

Rina Barouch-Bentov, PhD, presented her research at the 5th Annual Stanford Research Park (SRP) Symposium and Poster Session. The SRP symposium brings together investigators, trainees, clinicians, and research staff from across SRP to share science, build connections, and highlight the range of research happening in the community.

Her poster titled “Isolation and In Vivo Testing of Clostridium cuniculi Supports Its Role as Etiologic Agent of Infectious Diarrhea in NSG-Related Mice” was well received. Dr. Barouch-Bentov is a member of the Veterinary Service Center Animal Diagnostic Laboratory, and as a clinical scientist, is involved in various research projects at Stanford.

Congratulations to Katelyn Santa Maria!

Katelyn Santa Maria, an outstanding senior at Stanford University, has been awarded the prestigious 2026 Bill Somerville Grassroots Community Award by the Haas Center for Public Service!

Katelyn's dedication to both her academic pursuits in pre-veterinary studies and her passionate commitment to animal welfare exemplify the values of community service and leadership. As Vice President of the Pre-Vet Committee and co-founder of both the Animal Service Project and People for Animal Welfare (PAW), she has made significant contributions to fostering a compassionate environment for both animals and the community on and off campus.

As an undergraduate, Katelyn enrolled in many Comparative Medicine courses, participated in Pre-Veterinary Society activities led by Dr. Kerriann Casey and Dr. Monika Huss, and pursued Directed Reading with Dr. Kate Gates. The Comparative Medicine faculty are thrilled to celebrate Katelyn’s achievements and wish her all the best as she prepares to continue her journey at the UC Davis Weill School of Veterinary Medicine this fall.

Congratulations to Chun (Annie) Chang, DVM, a graduate from the Master of Laboratory Animal Science (MLAS) program in the Department of Comparative Medicine. The Stanford Alumni Association has selected Dr. Chang as a recipient of the 2026 Community Impact Award, recognizing her exceptional leadership and dedicated teaching within the Veterinary Service Center workshops, as well as her thoughtful mentorship of incoming MLAS students. Faculty, staff, and trainees consistently describe her as a joy to work with—someone who brings enthusiasm, compassion, and kindness to every interaction. Her commitment to going above and beyond has made a meaningful impact on the MLAS community.

Dr. Chang presented two posters at the 2026 American Association for Laboratory Animal Science (AALAS) District 8 Meeting.  She won first place for her poster, "Determination of the Optimal Carprofen Dose for the Incisional Pain Model in Rats (Rattus norvegicus)." 

In addition, she was selected to deliver the District 8 AALAS Rising Star Talk, an honor reserved for emerging professionals in laboratory animal science. The Rising Star program provides a supportive, low‑pressure environment for early‑career scientists to develop their presentation skills and gain confidence as future leaders in the field.

Please join us in celebrating Annie’s achievements and her outstanding contributions to the MLAS program and the broader laboratory animal science community.

Sydney Steele’s MLAS Research Published in Hormones and Behavior

We are pleased to announce that MLAS alumna Sydney Steele’s research on animal welfare has been published in the prestigious journal “Hormones and Behavior.” This significant achievement highlights the positive impact of oxytocin on post-surgical wound healing, particularly in socially isolated animals and humans.

A special thanks goes to Dr. Karen Parker and Dr. Anna Ratuski for their invaluable contributions and dedication behind the scenes, as well as to everyone in the Veterinary Service Center (VSC) who made this project a resounding success. Their hard work and collaboration have been instrumental in advancing the understanding of animal welfare. This study not only fills critical gaps in the existing evidence base but also underscores the unique environment at Stanford that fosters innovative research. We are proud to be at the forefront of this important work, which has the potential to influence practices in the field.
