Bernice Agana, Ph.D.

Bernice Agana, Ph.D.

Research Interests: Role of O-GlcNAcome in breast cancer initiation, proliferation and metastasis.

Research Aims: The OGT interactome and O-GlcNAcome between cancer cells and cancer stem cells will be compared using quantitative proteomics. My research aim is to identify novel signaling networks, probe the potential interplay of Ser/Thr O-GlcNAcylation and phosphorylation, and reveal regulators of tumor-initiating ability.

Mentor: Lauren Ball, Ph.D.

Alex Andrews, Ph.D.

Alex Andrews, Ph.D.

Research Interests: The impact of tumor microenvironment stress on T-cell metabolism and function in cancer immunotherapy.

Research Aims: My research investigates the role of endoplasmic reticulum (ER) stress sensor PKR-ER like kinase (PERK) and its ability to modulate T-cell metabolism in response to tumor microenvironment stress, with the goal of enhancing cancer immunotherapies.

Mentor: Jessica Thaxton, Ph.D.

Nancy Echeverri-Ruiz, Ph.D.

Nancy Echeverri-Ruiz, Ph.D.

Research Interests: Understanding how BRCA1's role in transcription regulation influences genome integrity and cancer development.

Research Aims: My project seeks to extend our recent biochemical observations into human cell-based models. We've identified a new relationship between an established tumor suppressor (BRCA1) and an emerging player in cancer development (BRD4). My goal is to understand how BRCA1 regulates BRD4-dependent transcription and the effect it has on expression of major oncogenes. This work has specific ties to hypoxia, which may promote loss of BRCA1 and concomitant increase in BRD4 activity.

Mentor: David Long, Ph.D.

Research Interests: Cellular Interaction and Coordination between Epithelium and Mesenchyme during Development and Cancer.

Research Aims: My research aims to develop innovative perspectives to exploit the similarities and tease apart the differences between the embryonic developmental processes and cancer progression. With a particular interest in the tissue resident fibroblast, I aim to uncover novel cellular interactions in the tumor microenvironment, which ultimately could serve as therapeutic targets.

Mentor: Michael Ostrowski, Ph.D.

Catherine MarElia

Catherine MarElia, Ph.D.

Research Interests: Elucidating Mechanisms of Stromal Fibroblasts’ Impact on Tumor Cells in Pancreatic Cancer.

Research Aims: The aim of my research is to interrogate the effects of conditional expression of important signaling pathway members, such as IL-6, within the stromal fibroblasts on tumor cells to gain insight into the disparate pathophysiological effects of spatially distinct expression of these effectors during the progression of pancreatic adenocarcinoma.

Mentor: Michael Ostrowski, Ph.D.

Research Interests: Interleukin-like EMT Inducer (ILEI) Signaling in Metastatic Breast Cancer

Research Aims: Previously, my research focused on structural and biophysical characterization of the Tie2 endothelial specific receptor. Through the ITOS program, I hope to integrate techniques learned during my PhD training with in-depth signaling evaluation in vivo to further knowledge in breast cancer pathobiology.

Mentor: Philip Howe, Ph.D.

Toros Dincman, M.D., Ph.D.

Research Interests: Evaluating Interleukin-like EMT Inducer's (ILEI) role in therapeutic sensitivity in lung cancer.

Research Aims: My research aims are to further our understanding on cancer pathogenesis and identify clinically applicable treatment paradigms in hopes of improving patient survival.

Mentor: Philip Howe, Ph.D.

Denise Garcia, M.D.

Denise Garcia, M.D.

Research Interests: Development of alternate cancer immunotherapies in aggressive and therapy-resistant cancers.

Research Aims: My research will investigate the efficacy of novel alternative immunotherapies in aggressive cancer treatment and their mechanisms of action with regards to the tumor signaling pathway. I will also investigate the impact of combination immunotherapies on cancer growth, proliferation, and invasion.

Mentor: Nancy DeMore, M.D.

Stephen Iwanowycz

Stephen Iwanowycz, Ph.D.

Research Interests: Role of Innate Immune Cells in the Tumor Microenvironment

Research Aims: I am passionate about using science to advance precision medicine. I would like to build my research around investigating the signaling between the different cell types within tumors in order to develop targeted therapies to reverse immune suppression.

Mentor: Bei Liu, M.D.

Lawton Roberts

Lawton Roberts, Ph.D.

Research Interests: The Unfolded Protein Response (UPR) and Sphingolipid Metabolism in Cancer Cell Biology

Research Aims: As my research focus is in cancer cell biology, I aim to use cancer cell models and rodents, genetic techniques/manipulation, and confocal microcopy to address compelling questions in cancer biology research in an effort to specifically understand the effects of mycobacterium tuberculosis and interleukin-27 on human dendridic cells.

Mentor: J. Alan Diehl, Ph.D.

Reeder Robinson

Reeder Robinson, Ph.D.

Research Interests: Development of Experimental Therapeutics Against Multiple Myeloma

Research Aims: My research aims are to discover the target of our lead experimental compound E61, a compound that is synergistic with proteasome inhibitors in Multiple Myeloma, and to develop a more efficacious and metabolically stable derivative that we can move into clinical trials.

Mentor: Nathan Dolloff, Ph.D.

Kelly Wolfe, Ph.D.

Kelly Wolfe, Ph.D.

Research Interests: Ubiquitin Signaling during DNA Interstrand Crosslink Repair

Research Aims: Defects in interstrand crosslink repair can lead to Fanconi Anemia and hereditary breast and ovarian cancers. My research will explore how ICL repair is influenced by atypical ubiquitin linkages and use basic biology to provide insight into human health and disease.
