Heather Fairfield, MS
Research Associate III
Research Interests: My background is in molecular biology and Mendelian genetics with a focus in hormonal regulation of both metabolic genes and oncogenes. I am interested in the use of high-throughput sequencing (exome, whole genome, and RNA-Seq) to identify spontaneous mutations, and have been involved in the implementation of these techniques in mice. I received my B.A. in Biology from the University of Vermont studying the mouse mammary tumor virus and a M.S. in Biology from Wake Forest University investigating the regulation of the leptin gene by steroid hormones. I am very interested in the relationship between adipocytes and multiple myeloma (MM) cells within the bone marrow (BM) niche, and what potential MM-nourishing signals may be released by these BM-adipocytes. I’m also interested in the genetic characterization of MM cells: both primary, potentially initiating mutations, and secondary events that may lead to distinctive gene expression signatures and disease progression.
Carolyne Falank, PhD
Research Interests: I obtained my B.S. in Marine Science at the University of Maine in Orono, Maine in 2005, my M.S. in Applied Medical Sciences from the University of Southern Maine in Portland, Maine in 2009 and my Ph.D. in Biochemistry and Molecular Biology from the University of Maine in Orono, Maine in 2015. During my graduate research, I studied the carcinogenic. I will be focusing my research on the design of nanoparticles that will be used to deliver therapeutic drugs that target bone disease and Multiple Myeloma. These nanoparticles will facilitate drug delivery that will be tested in both in vitro and in vivo models, with the hope that this will provide more efficient and effective delivery techniques to multiple myeloma patients while impeding tumor growth in the bone. In addition, I will help with other projects in the characterization and discovery of how cells in the bone marrow niche work in the progression of Multiple Myeloma. Learn more about Dr. Falank’s research.
Research Interests: As an intern in the Reagan lab, I was focused on inhibiting Multiple Myeloma (MM) from homing to the bone marrow via sialylation. MM can be shielded by the bone from various chemotherapy treatments, so if MM can be contained in the blood it may be easier to treat. After I graduated with my BS in Human Biology from University of Southern Maine in 2017, I have focused on several projects such as the effects bone marrow adipocytes have on MM and how this can trigger specific responses to drug treatments, and using carbon nanotubes as a form of delivery system in the body.
Katherine Bonawitz, BS
Research Associate I
Research Interests: I am a recent graduate of the University of Southern Maine with a B.S. in Biology. I enjoy cycling, hiking, volunteering, and hanging out with my dog, Mikey. Academically, my interests include developmental biology and medicine. I am excited to be a part of the Reagan lab as I begin the next steps in my education and I hope to contribute to a better understanding of multiple myeloma.
Research Interests: I am currently working toward earning my degree in Biology with a Human Concentration at the University of Southern Maine. My passions are science and art and I live locally here in Maine, as I have my whole life. I am thrilled to be a part of Dr Reagan’s research and look forward to contributing to the team as I pursue my education.
