Her research also involves characterizing the clinical pharmacology of investigational and approved anticancer agents in laboratory models and cancer patients to improve drug therapy. Dr. Baker’s lab works in a collaborative team environment so that the most promising preclinical findings are translated to clinical trials, and in turn, clinical observations provide feedback to inform preclinical studies.
Moray Campbell, PhD
Dr. Campbell’s research goals include understanding how epigenetic disruption of transcriptional programs drive hormone-responsive cancers, such as prostate and breast cancer, and exploiting this understanding in diagnostic and therapeutic settings. Specifically, he has focused on distortion of the actions of nuclear hormone receptors in these cancers, via several mechanisms including altered functions of co-regulators, such as NCOR2/SMRT, and disrupted targeting by non-coding RNA, such as miRNA. Within the context of prostate cancer, Dr. Campbell has extended this work to examine epigenetic mechanisms that contribute to cancer health disparities. To achieve these goals, his research focuses on the analyses and integration of high-dimensional datasets to dissect genomic and epigenomic mechanisms.

Christopher Coss, PhD
Roughly half of all cancer patients experience unexpected weight loss as a consequence of their disease. This phenomenon is known as cancer cachexia and is associated with reduced quality of life, increased risk of adverse response to cancer treatment and overall increases in cancer-related death. Despite being recognized for millennia, cancer cachexia has no known effective treatment. Dr. Coss’ Lab focuses on therapeutically targetable cachectic mechanisms. The drivers of cachexia are not well understood and an improved understanding of anabolic resistance and catabolic processes in cachectic animal tissues inform his team's novel therapeutic approaches for the treatment of cancer cachexia. His lab also focuses on chemotherapeutic drug disposition in cachectic cancer patients. Incredible heterogeneity exists between cancer patients’ body composition and how drugs behave once administered. An improved understanding of how patient body composition impacts chemotherapeutic drug disposition will inform the design of improved chemotherapeutic dosing regimens.
Yizhou Dong, PhD
Dr. Dong’s research, cell-specific and multifunctional drug delivery in vivo, has been regarded as one of the most challenging issues in the field of drug delivery.

An even more formidable task is delivering multiple payloads into specific cells and tissues. In order to address these challenges, Dr. Dong’s Drug Discovery and Delivery Laboratory focuses on the following research areas, developing cell specific drug delivery systems, constructing multifunctional drug delivery systems and demonstrating therapeutic efficacy of these systems in animal models for treating genetic disorders, infectious diseases and cancers.
Platform biotechnologies under development in the Drug Discovery and Delivery Laboratory include:
- Developing new biomaterials for therapeutic and diagnostic applications
- Engineering RNA molecules including mRNAs and the CRISPR systems
- Constructing targeted drug conjugates such as antibody/ligand drug conjugates.

Dale Hoyt, PhD
The circulatory system delivers blood to all parts of the body, and is compromised by many diseases such as atherosclerosis, stroke and heart attacks. Blood vessels may also grow into cancerous tumors and help them to expand and metastasize. By discovering drugs that can help or hurt blood vessels, they may be able protect the circulatory system and normal organs or inhibit cancer growth. Dr. Hoyt’s lab focuses on how stresses, including DNA damage, bacterial infection and inflammation can be manipulated to help or hurt blood vessel cells. His lab is assessing new drug targets in vascular cells to accomplish this.
Shuiying Hu, PhD
Many chemotherapeutic agents can cause neurological side effects, impacting quality of life. The incidence of chemotherapy-induced peripheral neuropathy (CIPN) is particularly high with agents such as paclitaxel and oxaliplatin, occurring in up to 80% of patients receiving such agents. There are currently no effective strategies for prevention of CIPN, and rationally designed intervention studies are needed to better address this gap. Dr. Hu’s research interests are focused on the development of transport modulators that could be used in conjunction with neurotoxic chemotherapy to understand drug transporter regulation mechanism; to determine the role of drug transporters on anticancer agents induced inter-individual pharmacokinetic variability, antitumor efficacy and drug to drug interaction; to evaluate contribution of solute carrier to chemotherapy-induced CIPN; and to develop preclinical and clinical studies with potential implications to ameliorate the incidence and severity of debilitating side effects of cancer drugs.

Dr. Peterson’s research group is working to discover small molecules that affect the proliferation of cancer cells and associated immune cells that support malignancy. To find these compounds, the Peterson laboratory creates fluorescent molecular probes that are designed to facilitate drug discovery. These probes are used in conjunction with phenotypic drug discovery methods to identify both anticancer agents with novel mechanisms of action and their molecular targets. To optimize and evaluate these compounds, they use synthetic organic chemistry, medicinal chemistry, and chemical biology approaches. These strategies, in conjunction with assays based on confocal microscopy, flow cytometry, and other fluorescence-based techniques, provide a platform for the identification of new therapeutic agents.

Jack Yalowich, PhD
Dr. Yalowich’s lab focuses on the mechanisms of action and resistance to a class of anticancer agents known as DNA topoisomerase II (topo IIα) inhibitors, such as the anticancer agent etoposide; a natural product analog. Ongoing projects characterize alternative RNA processing of topo IIα pre-mRNA that results in decreased expression of topo IIα in acquired resistance to etoposide. Strategies to circumvent drug resistance involve CRISPR/Cas9 gene editing to restore proper RNA splicing function in resistant cells. In addition, the role of micro-RNAs as determinants of anticancer drug resistance is under investigation. A variety of natural products are also under study as new and effective anticancer agents. Finally, members of the Yalowich lab actively collaborate with Dr. Mark-Mitton-Fry to evaluate the mechanisms of action and efficacy of newly synthesized Novel Bacterial Topoisomerase Inhibitors (NBTIs).
