Dr. Ubels recently retired from teaching but continues to maintain an eye research lab at Calvin in collaboration with students. Over the past 40 years he has published papers on every part of the eye of fish, amphibians and mammals, including humans. He also leads an interim service-learning course to Tijuana, Mexico in which students provide glasses to people without adequate access to eye care. Dr. Ubels enjoys sailing, cross country skiing, and classical music.
Research and Professional Interests
- Function of the lacrimal gland and cornea as related to dry eye disease. We are currently studying secretion of potassium ion by the lacrimal gland and the possible role of the relatively high concentration of potassium in tears in protecting the corneal epithelial cells from ultraviolet light. This research is funded by the National Eye Institute.
