Founder and CEO
Michael Browning, Ph.D. was born in Dallas, Texas and attended the University of Texas where he received a bachelor’s degree in English Literature. He then spent 5 years trying to become a filmmaker in Los Angeles and he sold shoes to pay his bills. He became very interested in how the brain processed visual images and abandoned filmmaking to start graduate school in Neurobiology in 1974. He received a Ph.D. in Neurobiology from the University of California at Irvine in 1979. He subsequently did a postdoctoral fellowship at Yale and Rockefeller University from 1980 to 1986 with Dr. Paul Greengard who won the Nobel Prize in 2002. Dr. Browning has a wife and two grown sons. In his spare time he enjoys golf, spending time with his family, and relaxing in his hot tub.

Dr. Browning is the founder of PhosphoSolutions, LLC. He is internationally known for his studies of protein phosphorylation and memory. In addition to his research and development work with PhosphoSolutions, Dr. Browning also was a professor of Neuroscience and Pharmacology at the University of Colorado Health Sciences Center (1987-2009) where he studied the biological bases of memory and how these processes are altered by aging and also by alcohol.


Kristin Nixon

President
Kristin Nixon was born in Miami, Florida. She attended the University of Colorado in Boulder and graduated with a bachelor’s degree in molecular, cellular, and developmental biology. Kristin planned to go to graduate school, but first spent some time traveling through the United States and South America. Somewhere in her travels, a love of cooking and food that began in college really seemed to flourish, and she became convinced that she wanted to go to culinary school rather than graduate school. However, after spending some time waiting tables and bartending, she became less certain that the restaurant life was what she truly wanted. She decided to try working in a lab full time to gain a better feel for different types of microbiology graduate programs, and was hired as a research assistant in Dr. Browning’s academic lab. To aid their studies, the lab generated their own antibodies, and Kristin began working for Dr. Browning’s prototype company, Tangible Research Solutions, producing NMDA antibodies.

Kristin started with PhosphoSolutions when it was founded in 2001. She continues to enjoy all things food and drink, travel (especially relating to food and wine), and spending time with her miniature dachshund, Macy.
