Faculty in the Department of Biology at Drexel University
Research Interests: Regulation of cell metabolism and its relevance in major human diseases such as cancer, cardiovascular disorders and diabetes.
Adjunct Faculty at the Wistar Institute
Dario Altieri, MD *
Research Interests: The mechanisms that underlie how tumor cells survive and proliferate in cancer, in particular how tumor cells evade the normal processes that cause cells with genetic faults to self-destruct.
Alessandro Gardini, PhD
Research Interests: The epigenetic control of transcription during cell differentiation and oncogenesis.
Paul Lieberman, PhD
Research Interests: How certain viruses, including Epstein-Barr virus and Kaposi's sarcoma–associated herpesvirus, establish a long-term latent infection that can lead to cancer.
Luis Montaner, DVM, DPhil *
Research Interests: Mechanisms of disease in HIV-1 infection, and explores new ways to boost the natural function of the immune system in order to combat infection or viral-associated disease.
Maureen Murphy, PhD
Research Interests: The most frequently mutated gene in human cancer, the tumor suppressor protein p53, especially how genetic polymorphisms in the p53 tumor suppressor gene that are more common in African Americans affect the ability of this protein to induce apoptosis and growth arrest, and hence combat tumor development.
Yulia Nefedova, MD, PhD *
Research Interests: Her research focuses on understanding molecular mechanisms by which the bone marrow microenvironment promotes tumor survival and progression.
Joseph M. Salvino, PhD
Research Interests: Medicinal chemistry, lead optimization and drug development, organic synthesis, design and synthesis of chemical biology tools to assist in mechanistic studies.
Jessie Villanueva, PhD
Research Interests: Our lab studies the molecular pathways that become deregulated in melanoma aiming at identifying suitable targets for therapy, particularly for tumors with limited treatment options, such as those driven by oncogenic NRAS. Our research goals are to dissect the mechanisms mediating drug resistance and identifying new targets or vulnerabilities that can be therapeutically exploited to combat melanoma drug resistance.
Adjunct Faculty at Fox Chase Cancer Center
Research Interests: My laboratory seeks to understand how innate differences in DNA replication and/or repair impact two critical areas in precision oncology: (1) what underlies an individual’s cancer risk, and (2) how an individual will respond to cancer treatment.
Research Interests: DNA repair of mismatched bases and the cellular response to DNA damage. Identification of early genetic alterations in tumorigenesis.
Research Interests: Lu Chen lab uses CRISPR engineering, live cell imaging, and classic biochemical approaches to delineate the molecular and cellular mechanisms by which RNA and RNA-protein complexes contribute to epigenetics, chromatin organization, and genome maintenance. We are translating our basic science findings into new therapeutic strategies aiming to solve cancers and other aging-related degenerative diseases.
Research Interests: Signal transduction by small G proteins and their effectors and the role of these proteins in regulating cytoskeletal structure, tumor invasion, and metastasis; regulation of insulin signaling.
Research Interests: Goal of our research is to discover ways to improve the treatment of epithelial ovarian cancer.
Research Interests: Tumor microenvironment; we study cancer-associated fibroblasts and self-derived extracellular matrices to understand their biochemical and mechanical effects on tumorigenesis and stromal activation.
Research Interests: Computational structural biology, including homology modeling, fold recognition, molecular dynamics simulations, statistical analysis of the PDB, and bioinformatics.
Research Interests: Identifying drug survival mechanisms for novel therapeutic strategies to benefit patients. Developing organoid models for precision medicine. Determining pathways and mechanisms regulating chromatin modifiers and enhancer-promoter interactions in hematopoietic cells. Systems biology approaches to determine epigenetic plasticity and epigenome regulation.
Research Interests: Integration of systems biology approaches with high throughput screening and targeted pathway analysis to improve the efficacy of preclinical and clinical cancer therapies.
Research Interests: The Johnson laboratory studies mechanisms of DNA damage detection, repair, and signaling that occur in BRCA1 mutation-containing organisms and cancers. We use a range of approaches, including cell biology, mouse genetics, and therapy resistance modeling, to understand basic biological processes and their implications for tumorigenesis and chemotherapy sensitivity.
Research Interests: Molecular chaperone correction of missense mutations; genetic defects of methionine metabolic enzymes and human disease.
Research Interests: Mechanisms of drug resistance in gastrointestinal stromal tumor.
Research Interests: Epigenetic Mechanisms Driving Copy Gain, Amplifications and Drug Resistance.
Research Interests: Projects in the Whitaker lab aim to elucidate the molecular mechanisms coupling two key biological responses to oxidative DNA damage within G-quadruplex forming sequences. Specifically, base excision repair (BER) and the epigenic-like transcriptional regulation of key tumor suppressors and oncogenes. The long-term goal is to identify molecular targets that can be exploited to improve cancer therapies.
