Please tell us about yourself
After finishing my undergraduate degree in Chemistry from University of Pune in India, I moved to the U.S. to start my master’s in Biochemistry and Molecular Biology at Georgetown University. During this time, I became interested in cancer research and decided to pursue my Ph.D in Oncology and Cancer Biology. I applied to University of Texas Health Science Center San Antonio because of its unique Integrated Multidisciplinary Graduate Program, now called the Integrated Biomedical Sciences program which allowed me the flexibility to select a lab across any of the departments.
The Cancer Biology track within the department of Cellular and Structural Biology provided the appropriate platform for my training as a Cancer Biologist. Again the unique multidisciplinary nature of the program gave us the option to select elective courses across different tracks. Today, I can confidently say that picking UTHSCSA and the IMGP program has immensely benefited me by training me in multidisciplinary fields.
Please provide a few sentences summarizing your dissertation. What was the experience like for you?
The goal of my dissertation was to understand the different consequences of endogenous stress in the presence of defects in DNA damage and response pathways.
I examined two disparate fundamental questions; (i) The role of 53BP1 in replication progression and its impact on genomic integrity, especially in the context of BRCA1 deficiency (ii) Understanding the mechanism of diabetes onset in the absence of ATM.
Working on my dissertation was a great learning experience for me. It has taught me the value of perseverance as my very first project in lab failed. At that time, I never thought it possible that I would graduate with two successful projects.
However with the encouragement of my advisor, I kept pursuing different ideas and it culminated in two very interesting projects. Additionally, the diverse nature of the projects led to me being trained in an array of techniques and subjects.
Why are you passionate about your research topic? How did you first become interested in it?
The area of DNA damage repair and the diseases caused due to defects in this repair remain relatively unknown. This is partly due to the fact that incidence rates of these diseases are very low. For examples, there are about 200 patients with Blooms syndrome worldwide.
Ataxia telangiectasia is another such example which occurs in 1 in 40,000 births. However, children born with DNA repair defects have high mortality rates and most of them die within the first two decades of their life.
Hence, I was really passionate about understanding the different consequences of DNA repair defects in order to identify novel targets to improve treatment and reduce the high mortality seen in these children.
Most of our understanding of DNA damage response and repair comes from studies done in the context of exogenous acute damage. These findings although explain cancer predisposition in these patients, they do not explain why these patients also develop diseases such as neurodegeneration, immunodeficiency and diabetes.
Why a defect in the ability to repair DNA leads to diabetes remains unknown. This was the question that initially got me interested in my dissertation project.
Through my understanding of one of the disease phenotypes I hoped to get a greater understanding of the different consequences of DNA repair defects.
What was your best memory during graduate school or what did you learn?
My best memory during graduate school was the day I had my dissertation defense.
It was a very satisfying experience to see the culmination of five years of work and to hear the positive response and support of my faculty and peers.
I will be starting as a postdoctoral researcher at Caris Life Sciences in Phoenix, AZ.
Any advice for your fellow graduate students?
Stay positive! There is a light at the end of the tunnel. Also, don’t be afraid to think out of the box. The risky ideas can sometimes lead to the most interesting results.
