I have a passion for science, and believe it represents an important path to truth. As a physicist, I search for fundamental explanations for our experience. For me, understanding how life can arise from the physical interactions of matter and energy is the greatest mystery. In my research, I apply quantitative methods to complex biological problems.

What I Love About Emmanuel:

I love that Emmanuel is a community. It is a place where students and faculty can know each other and work together in a way that would not be possible at larger institutions.

In 2021, Dr. Price was awarded a three-year, $378,754 grant from the National Science Foundation (NSF) to investigate how proteins find specific locations in DNA. The grant, and the research, marks the continuation of a decade-long project that began with an initial NSF grant in 2012 and another in 2017, for a total of nearly $1 million. Through their research, Dr. Price and a team of undergraduates have worked to understand how cells access genetic information and how they use it.

In 2017, Dr. Price received a three-year, $341,217 grant from the National Science Foundation (NSF) to investigate how protein molecules are able to find specific locations in the genome accurately and quickly-work that could have beneficial implications for the emerging field of gene editing, as well as the treatment of genetic diseases.

In 2012, Dr. Price, was awarded $232,922 over three years from the National Science Foundation for Developing Models of Facilitated Diffusion for DNA Binding Proteins. Professor Price will study DNA binding proteins and the ways that these diffuse one-dimensionally along the DNA until they find their targeted sequence. Research results will have translational impact as well as contribute to understandings important to lab-on-a-chip applications. Performing this research as an undergraduate institution, Professor Price will train and employ Emmanuel undergraduates in his lab, develop introductory Physics course materials, and create a professional development course for high school teachers.

I use quantitative science to understand the molecular basis of life. My students and I have developed methods to observe interactions between individual molecules of DNA and proteins. Our data has helped us understand how DNA binding proteins search the genome for their specific binding sites. This work has contributed to our fundamental understanding of genetic regulation in cells as well as to evolving biotechnology such as gene editing. We are also developing and applying methods in data science, such as computer vision and numerical simulations, to complex biomolecular processes.
