Congratulations to Alexa Johnson for presenting her research!

As a collaboration between UD ANFS graduate seminar and Cornell University’s Animal Science Department graduate seminar, Alexa Johnson, PhD student from the Biddle Lab presented a talk titled “Reemergence of cyathostomin species demonstrates anthelmintic resistance following drug administration” via Zoom Nov. 19. Congratulations to Alexa for being chosen for this honor, and for giving such a GREAT talk!

Congratulations to Kasey Hobert and David Vega

We would like to give a huge congratulations to Kasey Hobert and David Vega for WINNING first place in the CANR Research Symposium, One Health Presentation: Equine Gut Protozoans – The development of the Equine Protozoa Reference Manual on October 30th!

The team was mentored by  Alexa Johnson who helped guide them throughout their project and presentation. Hobert and her research partner David Vega earned the top spot in the one health category for their studies on equine gut protozoans. The pair worked on the development of a reference manual. Vega was naturally anxious to present among Ph.D. students and post-doctoral researchers.

“Everyone was so friendly and supportive and it was an incredible learning experience,” said Kasey Hobert, a pre-veterinary medicine and animal biosciences major. “Doing research has been an amazing way to take concepts that I have learned in class and apply them to studying a topic that I am passionate about. For every undergraduate student, I highly recommend getting involved in research.”

University of Delaware doctoral candidate Alexa Johnson grew up in California. She stayed in her home state to earn her bachelor’s and master’s degrees. But, when it came time for her doctorate, as an equine researcher studying health and disease, the California native knew she had to move across the country.

Summer Undergraduate Research Symposium

The Summer Undergraduate Research Symposium was held remotely this summer and required researchers to create and record a presentation using Zoom to illustrate their research! The symposium took place on August 13th and had more than 400 undergraduate researchers participating. The Biddle Lab had 8 undergraduates involved with 4 distinct research projects: Zoe Seitz and Allie Baiungo with Equine Gut Metagenomics. Michael Morguess and Christine Marchesano with The Equine Microbiome Project. Daniella Morris and Courtney Barbato with CKD Biomarkers. Lastly, David Vega and Kasey Hobert with Protozoans.
