Lin, Yu-Fen, PhD01.jpeg

Yu-Fen Lin, Ph.D.

Sr. Research Scientist


Yu-Fen received her Ph.D. in Biochemistry and Molecular Biology from National Taiwan University. She then worked with David Chen and Benjamin Chen at UT Southwestern to study how the DNA damage response is linked to replication stress. Yu-Fen joined the lab in 2020 with an interest in understanding the dynamics and kinetics of DNA repair across the cell cycle. She enjoys watching Harry Potter movies and spending time with her 75 lb. Labrador/Boxer mix.

Hu, Qing (Emily), PhD01.jpeg

Qing Hu, Ph.D.

Postdoctoral Fellow


Qing received her Ph.D. in Genetics from the University of Chinese Academy of Sciences studying meiotic DNA double-strand break repair and joined the lab in 2019 as a postdoc. She is currently investigating how the DNA damage response shapes the chromosomal rearrangement landscape of cancer genomes. Qing's favorite movie is Amélie.

Dahiya, Rashmi, PhD01.jpeg

Rashmi Dahiya, Ph.D.

Postdoctoral Fellow

Rashmi received her Ph.D. in Life Sciences from Jawaharlal Nehru University studying transcriptional regulation in budding yeast and joined the lab in 2019 as a postdoc. Her project focuses on the evolution of genomic rearrangements during kidney cancer progression. In her free time, Rashmi loves watching The Big Bang Theory.

Mazzagatti, Alice, PhD01.jpeg

Alice Mazzagatti, Ph.D.

Postdoctoral Fellow


Alice received her Ph.D. in Genetics, Molecular, & Cellular Biology from the University of Pavia, where she studied mammalian neocentromere evolution. She then trained at the Barts Cancer Institute focusing on chromosomal instability and DNA replication stress. Alice joined the lab in 2021 with an interest in understanding how DNA replication stress acts as a source of mutagenesis in cancer genomes. In her spare time, Alice pretends to learn to play the electric guitar.

Amanda received her M.D., Ph.D. from the University of Illinois at Chicago studying telomere protection and length regulation. She then completed Internal Medicine residency training at UTSW where she is now a Medical Oncology Fellow. Amanda joined the lab in 2023 as part of the Physician Scientist Training Program with an interest in how telomeres are maintained during the formation of complex genome rearrangements. During her spare time, she loves to read, tries to garden, and spends time with her two daughters.

Dhital, Brittiny 01.jpg

Brittiny Dhital, Ph.D.

Postdoctoral Fellow


Brittiny received her Ph.D. in Genetics, Genomics, and Cancer Biology from Thomas Jefferson University studying how prostate cancers adapt to high levels of chromosomal instability. She joined the lab in 2024 as a postdoc, where she is using functional genetic screens to uncover vulnerabilities associated with recurrent chromosomal alterations in kidney cancer. Brittiny claims to be a rare breed of Canadians who do not enjoy hockey. 

Maurals, Elizabeth (LIzz), BS01.jpeg

Elizabeth 'Lizz' Maurais

Ph.D. Graduate Student | Genetics, Development, and Disease Program


Lizz received her B.S. in Biotechnology from the University of New Hampshire at Manchester and conducted research as an Amgen Scholar at Caltech. She first joined the lab as a research tech in 2019 and then as a Ph.D. student in 2020. Lizz is currently studying the biological consequences of cytoplasmic DNA derived from mitotic errors. She loves spending time with her 3 lb. Chihuahua, Trudy, while watching The Office.

Engel, Justin, BS01.jpeg

Justin Engel

Ph.D. Graduate Student | Cancer Biology Program

Email | Twitter

Justin received his B.S. in Cell and Molecular Biology at the University of South Florida where he studied the response to DNA replication stress. He then joined Tango Therapeutics and conducted genome-wide CRISPR screens to identify synthetic lethal cancer targets. Justin is currently interrogating the mechanisms contributing to genomic rearrangements using unbiased genetic approaches. In his spare time, he enjoys cooking and spending time outdoors with his dog, Sully.

Wu, Nemo 01.jpeg

Bing-Huan "Nemo" Wu, M.S.

Ph.D. Graduate Student | Genetics, Development, and Disease Program


Nemo received his B.S. and masters degrees in Molecular Medicine from National Tsing Hua University in Taiwan. He joined the laboratory in 2024 with an interest in studying how chromothripsis contributes to cancer development in the context of glioblastomas and osteosarcomas. In his spare time, Nemo enjoys playing softball and LEGO building.

Ko, Ahyeon 01.jpg

Ahyeon Ko

Research Technician II


Ahyeon received her B.S. in Biochemistry from the University of Texas at Austin. She joined the lab in 2024 as a Research Tech/Lab Manager. Ahyeon manages day-to-day operations for the lab and provides support for multiple research projects. She enjoys spending time with her two cats, Ssol and Luna.
