Associate Professor, Cell Systems and Anatomy, GCCRI

My research focus is on DNA damage response and DNA repair, with a particular interest in Ewing sarcoma, breast cancer and Ataxia telangiectasia looking at cancer, development and aging. Since becoming an independent investigator, I have trained five postdoctoral fellows all of whom remained in science. In fact, since coming to UTH-SA, I have developed a postdoctoral career workshop, am a member of a Departmental committee to promote postdoctoral career advancement and most recently initiated a Departmental Postdoctoral Seminar Series. I am therefore a strong advocate for finding means for postdoctoral fellows to achieve their career goals. I have also been fortunate enough to have recruited several talented graduate students, six have now graduated and all pursued further research careers in either academia or private industry. I am currently training four graduate students. Over the last few years five of my graduate students obtained independent funding (including DoD BRCP program and PCRCP Horizon Award), as did three of my postdocs (including DoD BCRP and AstraZeneca-AACR START).

Manish Parihar, PhD

Research Scientist (2020 – )
EmailGoogle ScholarLinkedIn

Manish received his PhD from the University of Texas at Arlington in 2014 and his postdoctoral training at UT Health San Antonio. He studies the genetic disease ataxia-telangiectasia (AT) and is dissecting the role of amino acid transporters in disease development using molecular and cell biology techniques. Such transporters have the potential to be targeted for therapeutic intervention in AT. Manish was awarded the NIH sponsored IRACDA/SABER Associate Scholarship for postdoctoral training at UT Health San Antonio and outside research, he enjoys reading and swimming.

PhD student (2016 – )
LinkedIn Student ProfileEmail

“My project focuses on the connection between transcription, splicing, and transcription-associated stress (such as R-loops) in the context of Ewing sarcoma. I am using a variety of cell and molecular biology methods to determine how these processes are altered in Ewing sarcoma and investigate novel therapeutic targets.”

Kevin F. Kanda

PhD student (2018 – )

“The overall focus of my project is to investigate how altered metabolic pathways in Ewing’s Sarcoma drive its pathology, specifically in the context of DNA repair and epigenetics. I will be exploring metabolic response using a variety of techniques to quantify the production of reactive oxygen species and antioxidants as well as their overall effects on cell viability and DNA repair/modification.”

Henry E. Miller

PhD student (2018 – )
GitHub LinkedIn Student ProfileEmail

Henry is a PhD student in the Biology of Aging track of the Integrated Biomedical Sciences program. He is interested in applying molecular and computational approaches to understanding biological systems in cancer and aging. The focus of his project is to understand the role that R-loops play in normal physiological processes and the mechanisms by which those roles are disrupted with aging and cancer.

Henry received his B.S. from Christopher Newport University in 2016 and went on to study Biomedical Engineering at SUNY Buffalo, earning an M.S. in 2018. While earning his master’s, Henry became involved with biotech startups and learned programming with Python. He is the co-founder of the Bioinformatics Interest Group club at UTHSA, in which he leads a bioinformatics workshop. Outside of school, Henry enjoys hiking and playing jazz piano.

Pramiti Mukhopadhyay

PhD student (2018 – )

“My research focuses on examining the phenomenon of replication stress, specifically in Ewing sarcoma. I will be using various molecular and cell biology techniques to study the mechanisms in which proteins found at replication forks and involved in DNA damage repair pathways regulate the consequences of replication stress, thereby allowing Ewing sarcoma tumor cells to maintain stable genome integrity despite high levels of replication stress.”


  • 2020 – CPRIT Training Grant RP170345 Predoctoral Fellowship

Aiola Stoja

PhD student (2020 – )

Aiola received her Biotechnology B.S degree from James Madison University in 2016, after which she worked at the University of Virginia and at the UT Health Science System as a Research Assistant. During this time, Aiola developed skills in computational biology and chromatin remodeling, which she is looking to implement in her PhD by studying R loops in Ewings Sarcoma. The goal is to be able to use a computational biology and research oriented approach to elucidate how R loops effects Ewings Sarcoma and potentially other cancers as well. Aiola is Historian of the Bioinformatics Interest Group and in her free time enjoys camping with her dogs and drinking coffee.

Raquel Neves

Visiting scholar, UT Health San Antonio (2021- )
PhD Student, Santa Catarina Federal University (2019- )

Raquel is currently in our lab as a visiting student and her project focuses on the mutant p53 gain-of-function (GOF) activities in triple-negative breast cancer, particularly the promotion of an inflammatory profile in this type of cancer. Raquel is a Biotechnologist, received her M.S degree in 2019 and now she is part of the Biochemistry graduate program at Santa Catarina Federal University in Brazil.

Aparna Gorthi, PhD.

Post-doctoral student (2015 – present)
PhD student (2010 – 2015)
LinkedInResearch GateScholar Email

Aparna Gorthi is an AACR-AstraZeneca START postdoctoral fellow. She studies the cross-talk between DNA damage response, transcription and epigenetic regulation and their shared utilization of key factors like BRCA1 and STAG2 in Ewing sarcoma. Her approach combines molecular, cell biology based experiments and computational techniques to delineate systems biology of transcriptional stress response. In her research project, she studies the causes and consequences of R-loop accumulation and its role in epigenetic regulation.

Aparna hails from India where she completed her B.Engg in Computer Science, and a Masters in Biological Sciences from the Indian Institute of Technology Kanpur. She then worked at Philips Research Asia-Bangalore as a computational biologist for a few years before starting graduate school at UTHSA with Alex Bishop. During her graduate work, she discovered pervasive accumulation of R-loops in Ewing sarcoma and was able to mechanistically describe the underlying sensitivity to PARP inhibitors.  Aparna enjoys reading, music and road-trips with her husband and son.
