Research Interests:

 

My laboratory is interested in the regulation of a key tumor suppressor, the transcription factor p53.  p53 is mutated in over 50% of human cancers and has therefore been the subject of intensive basic and preclinical investigation. In the hope of improving cancer therapies that specifically target p53 mutations, we are investigating the role of different p53 mutations in driving tumorigenesis. For this we are using novel combinations of extant mouse models of cancer, murine xenografts and sophisticated tissue culture systems.

 

My laboratory is also looking into targeting the p53 pathway in skin stem cells to develop novel therapies for pigmentary disorders such as vitiligo. We and others have demonstrated the central role of p53 in pigmentation. Therefore, activating p53 in a complex disease such as vitiligo promises a truly safe and effective treatment alternative to the traditionally used ultraviolet light therapy.

Experience: While pursuing my undergraduate degree, I worked in a molecular biology lab on projects characterizing the HIV protease autoprocessing reaction and studying the in vivo binding of an aptamer to the flavivirus NS5 capping enzyme. During my undergraduate summers, I worked with the Schizophrenia Education and Training Program at UC Denver Anschutz Medical Campus looking at rat and mouse models of schizophrenia.

In the summer of 2014, I joined Dr. Terzian’s lab as a University of Colorado Cancer Center Summer Fellow. My project focuses on the study of the regulation of mutant p53 in development and tumorigenesis by its negative regulators, Mdm4 and Mdm2.

Hobbies: When I’m not in the lab I spend my time reading books, crocheting stuffed animals, playing the tuba, and singing with the Arrhythmias, the Anschutz Medical Campus choir.

Bio:  I am a Dermatology Research Assistant working alongside Drs. Tamara Terzian and Neil Box since April of 2013. My research interests include Cancer Genetics and tumor suppressor p53’s role in tumorgenesis. Specifically, I am interested in the roles and mechanisms of action of p53 and its regulators on tumor initiation and progression.  Prior to joining the lab, I interned in Dr. Dennis Roop’s lab where I expressed gain of function p53 mutants in a skin carcinoma cell line, which sparked my interest in cancer research.

I am an avid advocate of awareness and prevention; and thus, by expanding my knowledge on the matter, I have become a more resourceful, educated individual. Outside the lab, I highly enjoy cooking and exploring the wonderful outdoors that Colorado has to offer.
