Career Path

I started this career in reproductive biology as a student intern/part-time research assistant in the animal breeding and embryology lab at National Taiwan University. I have always had a great passion for reproductive biology, seeing cleaving mammalian embryos under a microscope for the first time was one of the most fascinating moments in my life. During the lab internship, I learned a wide range of basic skills in research and farm animal handling (which was often more fun than lab bench work). After completing two years of military service in the Taiwan Army, I started graduate school at the University of Wisconsin-Madison, one of the best reproductive biology training programs in the country, where I focused on cellular and molecular embryology and stem cell biology. Throughout my student and faculty career, I have worked on embryos and gametes of various species including domestic animals, rodents, wild animals, nonhuman primates (both Old World and New World monkeys), and humans, as well as embryonic stem cell and transgenic/cloning projects. This broad training in research, a strong skill set in embryology, and a good balance in both big-picture and detail-oriented assessment, led to a very fulfilling faculty career here at UT Health San Antonio. The current multitasking role in clinical lab directing, research, management, technology development, teaching, and service in the professional community, is fun and demanding at the same time. It is extremely rewarding to participate in the rapidly evolving field of reproductive medicine and technology, and be a pivotal part of our successful UT Health Women’s Health Center clinical team providing top quality patient services.
