Research Interests
The Roberts lab is interested in studying the interaction of drugs with multiple-drug resistance transporters and drug-metabolizing UDP-glucuronosyltransferases. These proteins play major roles in cancer resistance, in neurological diseases (e.g. Alzheimer’s disease and Parkinson’s) and in mitigating the effects of environmental pollutants. Using human proteins isolated from genetically engineered yeast or bacteria, one goal is to develop structural biology tools to rapidly and accurately predict the effects of drugs and toxins before they end up in people. These tools will allow them to design next generation drugs that are more effective and have fewer side effects than current medications. Another goal is to develop advanced NMR and computational methods to probe the effects of drugs and toxins in whole cells. These techniques will allow them to probe the complex interplay between transporters, receptors and enzymes during drug and metabolite processing. In addition to these research goals, the Roberts lab is developing creative and novel teaching methods to train students of different skill levels in his laboratory. Achieving these research and teaching goals will not only advance medicine and improve drug therapies, but will prepare students well for industry or academic careers in the 21st century.
