The Science Page of Brian Parks



Thanks for visiting!

I retired in 2016 as a Faculty Associate in the Department of Zoology at the University of Wisconsin - Madison. In this position, I was integrally involved in the Introductory Biology series for undergraduates at UW. My role in this course was both as an administrator and as a teacher, where the many challenges associated with bringing biology to students in a way that excited them and kindled a fascination for science were always evolving.

Before my ivolvement in Introductory Biology, my focus was basic research in plant photobiology. For over 25 years, I studied how plants utilize light as a signal to direct their growth and development throughout their life cycle. This process is known as Photomorphogenesis. This is different from photosynthesis where light is used in far greater amounts as a source of energy. Plants have evolved a number of photoreceptors for the purpose of monitoring light as a signal. Of these, the one that garnered most of my interest and attention is a class of signaling molecules known as the Phytochromes. If you would like to know more about my past research, please follow the scientific links to the right to learn in more detail what I studied during my career as a laboratory researcher. I apologize for how old they are, but they still work!

Or head to the bottom ("Plate") for something different.

And please feel free to contact me if you have further questions not answered here.

...Thanks Again!
