  • DNA replication and repair, and the roles of these pathways on cancer initiation, progression and response to chemotherapy and immunotherapy

Research Abstract:

Our laboratory focuses on DNA replication and repair, and the roles of these pathways on cancer initiation, progression and response to chemotherapy and immunotherapy. We utilize a unique combination of biochemical, cellular, and electron microscopy approaches to study replication perturbations at single molecule resolutions. Combining these technologies, we have identified key pathways by which cancer cells respond to DNA damaging chemotherapy and have provided new insights on how to target these pathways to increase chemotherapeutic sensitivity.

We also are part of the newly established Siteman Center for Genome Integrity that fosters interactions between clinical and basic science investigators interested in genome integrity and DNA repair:

Ongoing projects:
1. Connecting DNA replication fork instability with cancer etiology and chemotherapy response in breast and ovarian cancer
2. Replication fork protection and recovery in homologous recombination deficient tumors
3. Adaptive response to chemotherapeutics
4. Role of the DNA damage response in normal and malignant hematopoietic cells
5. Connecting R-loop formation with chemotherapy response

Mentorship and Commitment to Diversity Statement:
Our lab is proud to be composed of a diverse community of scientists fascinated by the mechanisms that connect DNA and people together! We have trained 17 graduate students, 17 postdoctoral researchers, and over 25 undergraduate students from different nationalities and underrepresented minorities. In addition to our commitment to team science, we have a genuine interest in welcoming folks with diverse backgrounds and perspectives with the goal of fostering everyone's individual growth.
