The Science Page of Brian Parks

 

 

Thanks for visiting!

I am a Faculty Associate in the Department of Zoology at the University of Wisconsin. But, ironically, my training is as a Plant Scientist. I am integrally involved in the Introductory Biology series for undergraduates at UW. My role in this course is both administrative and as a teacher. The challenges associated with bringing material to students in a way that excites them and kindles a fascination for science are always moving in new directions.

As I said earlier, my area of expertise is plant photobiology. For over 25 years, I was involved in basic plant research that focused on 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 study in Prof. Spalding's lab.

…Or head to the bottom for something different.

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

...Thanks Again!
