Current Weiss Lab Members

Bob Weiss, Principal Investigator
Bob is a Professor of Molecular Genetics in the Department of Biomedical Sciences at Cornell University. He received an A.B. in Biology from Wabash College in 1992 and a Ph.D. in Molecular Virology from Baylor College of Medicine in 1997. He then trained as a postdoctoral fellow in the Department of Genetics at Harvard Medical School with support from an American Cancer Society postdoctoral fellowship. In 2002, Bob joined the faculty of Cornell University. He lectures in the core veterinary curriculum, teaches a graduate course on genome maintenance mechanisms, and leads a research program aimed at dissecting how mammalian cells maintain genomic stability, using mouse models and an array of genetic, molecular, cell biological, and genomic technologies.

Tim Pierpont, Graduate Student
Tim graduated with a BS from Delaware State University in 2011 and began the Biochemical, Molecular, and Cellular Biology field degree program at Cornell University later the same year. After initial lab rotations he joined the Weiss lab in May of 2012. His work in the lab focuses on elucidating the role DNA damage response pathways and stemness properties play in the development and treatment sensitivity characteristics of testicular germ cell tumors.

Elizabeth Moore, Graduate Student and Lab Animal Veterinary Resident
Elizabeth graduated with a B.S. in Biotechnology from the University of Kentucky in 2008. She then completed a DVM at Cornell University in 2012 and is currently a veterinary resident in laboratory animal medicine with the Cornell Center for Animal Resources and Education. She is concurrently pursuing a PhD in Comparative Biomedical Sciences.

Yashira Negrón, Graduate Student
Yashira received her B.S. in Chemistry from the University of Puerto Rico, Río Piedras campus in 2012. Then, she began the graduate field of Chemistry and Chemical Biology at Cornell University and on May 2013, joined Weiss lab. Her research is focused on studying the role of Sirtuins in cancer metabolism by using knockout mice.

Darshil Patel, Graduate Student
Darshil graduated with his B.S. in Molecular and Cell Biology from UCLA in 2012 and decided to continue with his graduate education at Cornell University. He joined in the field of Biochemistry, Cell and Molecular Biology and decided to continue research in Weiss Lab. His primary study in lab is focused on understanding the role of Hus1 and its protein interactions in regulating DNA damage repair. Currently, he is interested in elucidating the role of different 3'UTR isoforms of Hus1 and how they regulate its gene expression.

Catalina Pereira, Graduate Student
Catalina received her B.S. in Biology from Mount St. Mary's University, in Los Angeles in 2013. In 2014 she began her graduate studies in the field of Biochemistry, Cellular, and Molecular Biology at Cornell University and joined the Weiss lab. In the lab, her research will focus on continuing to determine novel protein interactors with Hus1, examine regulation of HUS1 transcript isoforms, and study how specific mutations in key residues of HUS1 compromise the 9-1-1 complex.

Ellen Hong, Undergraduate Student Researcher
Ellen is a Biological Sciences major in the class of 2017. She joined the Weiss lab in the fall of 2013 and intends to continue with research in her undergraduate years at Cornell. Although she is not sure of what she wants to do after Cornell, she is thinking of going to graduate school to work towards a PhD.

Kathleen Miao, Undergraduate Research Assistant
Kathleen is a biology major in the class of 2017. From California, she joined the Weiss lab in the fall of 2014 and looks forward to researching throughout her undergraduate years. After graduating from Cornell, Kathleen hopes to attend medical school and help patients as a physician and medical researcher.
