Rachel O’Neill, PhD, PI







Judy Brown


Dr. Judy Brown is an Assistant Professor in Residence in the Department of Allied Health Sciences at the University of Connecticut and a certified clinical specialist in human cytogenetics and molecular biology. She is co-director of the University of CT Induced Pluripotent Stem Cell and Chromosome Core. Her research is the examination of chromosome interactions at evolutionarily conserved, cancer-prone breakpoints. Dr. Brown also collaborates with Dr. Rachel O’Neill (Genetics and Genomics in the Department of Molecular and Cell Biology) in the investigation of chromosome instability, retroviruses and evolution in a number of model systems including human, primate, mouse, marsupials and species hybrids.

Graduate Students



Michael Perrachio

Mike Perrachio graduated in 1999 with a BS in Ecology and Evolutionary Biology.  He earned an MS in Secondary Science Education in 2007 from Eastern CT State University and  subsequently taught Biology at Coventry High School for 5 years before entering the PhD program in Genetics and Genomics at UCONN and joining the O’Neill Lab.



Sarah Trusiak

Sarah graduated with a BS in biomolecular sciences and chemistry in 2006 from Central Connecticut State University. She is a 4th year PhD student and her projects involve testing the centromere drive hypothesis in a marsupial model system.





Julianna Crivello

Julianna received a Bachelors of Science in Diagnostic Genetics Sciences with a concentration in Cytogenetics and a minor in Molecular and Cellular Biology in December of 2011.  She is currently an MCB Masters student working on the EBV project in the O’Neill Lab.





Brianna Flynn

Brianna earned her Bachelor of Science in Physiology and Neurobiology from the University of Connecticut, where she had the opportunity to do undergraduate research in Dr. O’Neill’s lab. Her laboratory research experience in Chromosome Kissing in Cancer led her to chose to continue at UCONN pursuing her graduate studies in Molecular and Cell Biology. She is currently a Genetics and Genomics student focusing on genomic instability and metastatic potential in the White-Footed Mouse utilizing a novel inbred line with a high rate spontaneous adenocarcinoma.

Brendan Smalec

Brendan is an undergraduate in the honors program majoring in molecular and cell biology and art history. He works with Brianna studying chromosomal and genomic abnormalities and how they relate to tumorogenesis and metastasis in the white-footed mouse, Peromyscus leucopus. After graduation, he hopes to attend an MD/PhD program and continue with cancer research.
