Dr. Cocucci studies basic mechanism of membrane trafficking and is interested in how these processes deviate during cancer development when compared to normal cells. His research adopts multiple techniques, including traditional biochemistry, cell biology and high resolution fluorescent live cell microscopy. Dr. Cocucci’s goal is to define novel targets for cancer therapy and to improve drug delivery, studying the internalization pathways and the mechanisms of endosomal escape adopted by artificial and biological nanovectors.
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. An improved understanding of anabolic resistance and catabolic processes in cachectic animal tissues inform our novel therapeutic approaches for the treatment of cancer cachexia.
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.

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, we may be able protect the circulatory system and normal organs or inhibit cancer growth. Dr. Hoyt’s lab focusses 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.
Robert J. Lee, PhD
Dr. Lee’s lab is working on developing nanoparticle-based drug delivery systems. Many cancer drugs have side effects and can be made safer and more efficacious with novel drug delivery systems. Other drugs such as oligonucleotides require an effective delivery system to be translated into the clinic. Dr. Lee’s lab is focused on developing lipid-based and targeted drug delivery systems for drugs and nucleic acids with potential applications in oncology and other diseases.
Jack Yalowich, PhD
For more than 20 years, Dr. Yalowich’s lab has conducted studies of a particular class of anticancer agents known as DNA Topoisomerase II (topo II) inhibitors. These drugs cause DNA damage and tumor cell killing. Major efforts are directed toward characterizing mechanisms of action of these drugs and overcoming drug resistance.
Dr. Yalowich’s current projects focus on:
Understanding how cancer cells modify the target enzyme (topo II) to avoid drug-induced cell killing
Strategies to “correct” topo II modifications and re-sensitize tumors to drugs
The use of nutritional antioxidants (such as vitamin C) to prevent cancer-causing effects of topo II inhibitors which can arise in some patients years after therapy is complete
Dr. Carnes’ research is focused on furthering our understanding of abnormal heart rhythms (arrhythmias) with the goal of optimizing treatment. A particular focus of her program is understanding the underpinnings of arrhythmias occurring during heart failure. A second aspect of Dr. Carnes’ arrhythmia research program is developing and validating processes to improve clinical pharmacy services for patients on long-term antiarrhythmic medication therapy.
Dr. Carnes is also interested in junior faculty development with an emphasis on providing foundations for research independence in clinical and translational research. This work is supported in her role as director of the KL2 scholars program at the Ohio State Center for Clinical and Translational Science.
Nearly three out of every five adults in the United States consume prescribed medications. Dr. Donneyong’s research focuses on the safety and effectiveness of medications and medical devices. Specifically, he applies quantitative methods from epidemiology, pharmacoepidemiology, biostatistics and data analytics to analyze large healthcare databases such as health insurance claims and other linked databases which capture prescribed medication use and outcomes on their safety and effectiveness. Currently, Donneyong focuses on:
Drug-drug interactions: The simultaneous use of multiple medications is growing increasingly common. He investigates whether it is safe to simultaneously use certain medications or not.
The role of the social determinants of health factors on the effectiveness of prescribed medications: He is interested in how the conditions in which people are born, grow, live, work and age influence the safety and effectiveness of prescribed medication use in the community settings.
Medication outcomes among racial/ethnic minorities: Through population-based observational studies, he tries to measure differences in the utilization, safety and effectiveness of prescribed medications between racial groups, as racial/ethnic minority groups tend to be under-represented in clinical trials of drugs.
The research in Dr. A. Douglas Kinghorn’s lab deals with the extraction, purification, and characterization of the chemical structures of biologically active substances of tropical plants. Examples of the use to society of these lead compounds are as potential cancer chemotherapeutic and chemopreventive agents, therapies for the tropical infectious disease leishmaniasis, and as sweetening and taste-modifying components of foods and beverages.
James Fuchs, PhD
The research in Dr. Fuchs' lab designs and prepares novel molecules for therapeutic applications against cancer and infectious diseases. His lab utilizes fundamental chemical knowledge and synthetic methodology to facilitate the process of drug discovery and development through the generation of biological probe molecules, the synthesis of lead compounds and the optimization of drug properties.
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. A wide variety of cell types in humans still cannot be efficiently and specifically reached by delivery systems such as lung epithelial cells, metastatic tumor cells, and immune cells. 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:
To develop cell specific drug delivery systems
To construct multifunctional drug delivery systems
To demonstrate therapeutic efficacy of these systems in animal models for treating genetic disorders, infectious diseases, as well as 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.
