Ronald Ackermann, MD, MPHProfessor, General Internal Medicine & Geriatrics
Professor, General Internal Medicine & Geriatrics
Dr. Ackermann's primary expertise is in the development and evaluation of healthcare-community partnerships to implement evidence-based health promotion, preventive, and chronic disease management services for adults. During the past decade, he has designed and directed a series of research studies focused on the translation, implementation, and evaluation of the Diabetes Prevention Program and Look AHEAD lifestyle interventions involving partnerships among busy healthcare providers and leading community organizations, such as the YMCA. In his role as Director of the Center for Community Health of the Northwestern University Institute for Public Health and Medicine, he has organized and participated in several large initiatives involving public-private partnerships to evaluate emerging policy questions, translate clinical trials, and address community health priorities. In this role, he is accountable for ensuring the success of other Northwestern University investigators and trainees who aim to engage primary care providers, community organizations, public health leaders, and patients in the design of research to improve health and healthcare.
Grant Barish, MDAssociate Professor of Endocrinology
The major focus of research in the Barish lab is to discover the epigenomic and transcriptional basis of metabolism and inflammation. Our recent work has helped to reveal the genomic architecture for transcriptional regulation in innate immunity. Surprisingly, while nodes of control are often at significant linear distance from regulated genes, the interplay between transcriptional activators and repressors is highly proximate, occurring at shared nucleosomal domains. Moreover, we identified a powerful role for the BCL6 transcriptional repressor in macrophage quiescence and the prevention of cardiovascular disease. Currently, we are exploring the impact of activator?repressor interactions on enhancer function and transcription, the signal-dependent control of repression, and the functional impact of transcriptional activators and repressors in cardio-metabolic disease. To these ends, we use a variety of genetic, molecular, next-generation sequencing, and biochemical methods as well as physiological models. We anticipate that these studies will provide insight into the underlying balance of transcription and its implications for the development and progression of disease.
Joseph T. Bass, MD, PhDProfessor & Chief, Division of Endocrinology, Metabolism & Molecular Medicine
Professor & Chief, Division of Endocrinology, Metabolism & Molecular Medicine
The major focus of research in the Bass laboratory is on the molecular links between neural circuits coordinating sleep, wakefulness and feeding behavior, with systems important in peripheral fuel utilization, including the insulin-signaling pathway. The major overarching theme of his research is to dissect transcriptional and posttranslational interactions between circadian and metabolic gene networks in the development of diabetes and obesity. These studies are an outgrowth of his discovery that mutation of the gene encoding the transcription factor CLOCK, present within both brain and in peripheral metabolic tissues, leads to altered sleep, feeding activity, obesity and diabetes. Projects in the laboratory now exploit both genetic and biochemical methods to pinpoint the cell and molecular basis for co-regulation of circadian, sleep and metabolic pathways within specific cells of hypothalamus, and peripheral metabolic tissues. This approach has elucidated a novel function for the clock gene network in glucose-stimulated insulin secretion (within Islets of Langerhans) and in control of feeding (in the POMC neuron). He has also pursued a series of biochemical analyses leading to the discovery that clock gene activators control endogenous NAD biosynthesis. Extensions of this work include analysis of altered protein acetylation within both nuclei and mitochondria of circadian mutants.

Amani Fawzi, MDProfessor, Ophthalmology
Alfred L. George, Jr., MDProfessor and Chair, Pharmacology
Richard Green, MDProfessor, Gastroenterology & Hepatology
Professor, Gastroenterology & Hepatology
The Green laboratory focuses on the molecular mechanisms of hepatic lipid metabolism and mechanisms of cellular injury. Non-alcoholic steatohepatitis (NASH) is one of the most common causes of liver disease in the United States, and accounts for the majority of cryptogenic cirrhosis. NASH is associated with the metabolic syndrome, which includes insulin resistance, obesity, and dyslipidemia, and type 2 diabetes. In addition, recent evidence indicates that there is a strong genetic component for the susceptibility and progression of steatohepatitis. NASH is a polygenic disease, and Quantitative Trait Loci analysis is a widely utilized genetic technique that can be applied to murine models in order to determine the chromosomal loci responsible for the expression of complex traits and polygenic diseases. In addition, mechanistic studies focus on hepatic gene expression and the role of nuclear receptors in regulating hepatic injury and fibrosis.

She currently directs an interdisciplinary research program to understand the causes of racial/ethnic disparities in cardiometabolic diseases and to develop interventions that address these disparities. Her research program addresses a weakness noted at the time of the last competitive renewal that our training program lacked opportunities for primary care/community based research.
William Lowe, Jr., MDProfessor Emeritus, Endocrinology, Metabolism & Molecular Medicine
Professor Emeritus, Endocrinology, Metabolism & Molecular Medicine
The Lowe laboratory in collaboration with the Kaufman laboratory and other investigators in Materials Science, and Biological and Chemical Engineering is seeking to develop novel approaches to enhance islet engraftment and function post-transplant as described above. Efforts are now under way to take advantage of the ability of these scaffolds to release bioactive molecules, either DNA or peptides, as a means to enhance the microenvironment of the transplanted islets and, thus, optimize the survival and revascularization of transplanted islets and, possibly, stimulate islet cell proliferation. The Lowe lab is seeking to develop approaches to differentiate embryonic stem cells into insulin-secreting cells.
A second interest of the Lowe laboratory is the interaction between the intrauterine environment and genetics in determining size at birth as well as genetic determinants of maternal metabolism. To address this interest, he, in collaboration with others at NU, is using DNA and phenotype information from ~16,000 mothers and their babies who participated in the Hyperglycemia and Adverse Pregnancy Outcomes (HAPO) Study. One of the underlying hypotheses being examined is that genetic variants that impact upon insulin sensitivity or secretion when present in mother and/or fetus result in variation in fetal growth. Planning has also been initiated to follow up a subset of the HAPO mothers and babies to examine the hypothesis that maternal glucose levels during pregnancy are positively correlated with measures of adiposity, lipidemia, glycemia, and BP during childhood.

Milan Mrksich, PhDProfessor, Biomedical Engineering, Chemistry and Cell and Molecular Biology
Professor, Biomedical Engineering, Chemistry and Cell and Molecular Biology
Research in the Mrksich Group emphasizes the design and preparation of surfaces for applications in the basic and applied biological sciences. One major theme uses a chemical approach to prepare two-and three- dimensional materials that serve as well-defined mimics of the extracellular matrix and which are used to understand the roles for distinct ligand-receptor interactions in regulating cellular processes. A second major theme develops high throughput assay formats based on the SAMDI label-free mass spectrometry method to assay biochemical function. These projects have evolved from my graduate training as a bioorganic chemist at Caltech and as a surface chemist while doing my postdoc at Harvard. Our program emphasizes the molecular design and synthesis of biologically active surfaces and is described in more than 120 papers during my independent career and by the placement of trainees in independent positions in academia, industry and related fields.
