Epivara (epi:epic, var:change) is bringing

Epic Change to the way spays and neuters are performed world-wide.

How we treat animals matters. That's why we created EpiFix, a new way to fix animals without painful, risky surgeries. 

Eliminating invasive surgery is always a good thing, but it's the impact that really matters. 

A low-cost single-injection makes it much easier and cheaper for spay/neuter organizations and shelters to fix homeless animals. That means better health, reduced overpopulation, and a happier life for vulnerable cats and dogs worldwide.

Our Mission is to make life easier and better for animals and humans through innovative science and compassionate care.

Rex A. Hess, PhD, is Epivara's Director of Science and Professor Emeritus of Reproductive Biology at the University of Illinois whose cat rings his doorbell during our meetings. He is also a prolific fundraiser. Since 1986 when he completed his post-doc at the EPA, he has raised a whopping $54 million in grants to fund his research. In his more than 30 years at the University of Illinois he has earned a dozen high-profile honors and held several positions on grant-review panels.

 

Early in his career, he discovered that a fungicide caused testicular atrophy

because it disrupted the function of efferent ductules in the head of the epididymis. He also found that efferent ductules express more estrogen receptor (ESR1) than even the uterus. His expertise in histopathology, electron microscopy, and reproductive toxicology has carried over into his life-long study of male reproductive biology. These efforts led to a more complete understanding of the stages of the seminiferous epithelial cycle and numerous collaborations on the direct effects of gene knockouts in the testis.

 

In the last four years alone, he has had 22 publications in peer-reviewed journals, solo authored two book chapters, and co-authored four others. For Dr. Hess, this is an ideal retirement.

Chan Jin is the newest addition to the Epivara family and brings with him a wealth of experience in animal reproductive biology. During his post-doc he led in depth studies exploring the function of steroid hormones in the reproductive organs of animals. He also has a strong background in molecular biology, anatomy, histology, and in-vivo toxicity assessment of chemicals.

Chan Jin is very excited to translate his expertise and years of research into creating a product that will improve the lives of animals and the people who love them. 

Also, he LOVES bowling.

Sherry Zhou, MD

Senior Scientist

Dr. Sherry Zhou has worked for almost 30 years studying the effect of lipids, especially oxidized cholesterol and trans fats, on human diseases. In recent years, she has focused on lipid metabolism and reproductive diseases prior to her retirement from UIUC.  She joined Epivara's Lab as a Senior Scientist in May, 2020.

Sherry brings many years of lab management experience to the team and is eager to help create a less stressful, painful, and risky way to sterilize animals.

The Scientific Advisory Board

G. Robert Weedon, DVM, is a feral cat surgeon with TLC PetSnip. He retired in 2018 as a Clinical Assistant Professor of Shelter Medicine at the University of
Illinois

Indrani Bagchi, PhD, is a Professor and Field Chair in Reproductive Biology at the University of Illinois

Krista Keller, DVM, is an Assistant Professor of Veterinary Medicine at the University of Illinois who specializes in exotic and avian species

Dr. Jay Ko is the Founder of Epivara and a Professor in the College of Veterinary Medicine at the University of Illinois. His dog Lenny is actually in charge.

 

Dr. Ko is a life-long animal lover who grew up on his parents' farm in South Korea. He attended Seoul National University (SNU) and taught Biology to middle school students before he went back to SNU for graduate school.  He graduated with a PhD in Developmental Biology in 1998 and did two post-docs at the University of Kentucky in the fields of reproductive biology and chemistry.

 

At the University of Kentucky, he took a faculty position in 2002, and taught human reproductive biology for 9 years until he found a new academic home in the College of Veterinary Medicine at the University of Illinois (UIUC) in 2011. At UIUC, he teaches reproductive biology and gastrointestinal biology to veterinary and graduate students. He also leads a vibrant team of reproductive biologists as a principal investigator (http://vetmed.illinois.edu/kolaboratory/)

 

His research has led to the publication of over 80 research articles, to his service on multiple NIH grant review panels, and to the receipt of many awards including the Zoetis Award for Veterinary Research Excellence and the Dr. Gordon & Mrs. Kruger Research Excellence Award. It goes without saying that Dr. Ko is a leading world-expert in reproductive biology, and it's that depth of experience and inquiry that led to the invention of EpiFix.
