Our laboratory is investigating the cellular processes and pathways that are involved in normal morphogenesis of epithelial tissues as well as those involved in the initiation and progression of epithelial tumors.
Our research focuses on deciphering molecular mechanisms that drive metabolic disease, and using this information to develop targeted therapeutic strategies. Mitochondria are critical hubs for metabolic signalling, and their dysfunction is key in the pathology of metabolic disease. We combine mass spectrometry and targeted pharmacological approaches in vivo to understand how mitochondrial redox metabolism controls physiology in clinically informative mouse models of obesity and diabetes.
The primary focus of our laboratory is to delineate cellular energy and nutrient sensing pathways, including metabolic checkpoints that integrate cellular survival and bioenergetics.

The Haigis laboratory focuses on the molecular regulation of mitochondrial functions during aging and age-related disease. Our goal is to investigate how pathways that control aging, such as sirtuins, impact mitochondrial fuel utilization, bioenergetics and signaling. To achieve these objectives, we take a multidisciplinary approach that employs biochemical, cellular, and mouse modeling experiments to systematically dissect the mitochondrial pathways of interest.

Our laboratory is interested in nutrient sensing in mammalian cells and how it connects to the transcriptional machinery to control gene metabolic regulatory networks.
We are interested in the molecular mechanisms by which proteins are transported across or are inserted into the endoplasmic reticulum (ER) membrane. We have dissected both cotranslational protein translocation in mammals and posttranslational translocation in yeast using a combination of biochemical approaches.
Our broad goal is to understand the function of human RNA machines, such as the SMN complex, the spliceosome and the TREX complex, in both normal and disease states with current emphasis on Amyotrophic Lateral Sclerosis (ALS) and cancer.
We study biochemical and cellular mechanisms involved in signal transduction through the Hedgehog signaling pathway. We also develop and apply new chemical technologies to study the cell biology of lipids.
The overall goal of our work is to solve biological problems using quantitative methods from bioinformatics, statistical physics, data sciences, statistics, computer science, and mathematics. We apply these computational methods to build predictive network models of molecular and cell-cell interactions, to support cancer precision medicine, and to make discoveries in structural and evolutionary biology.
We aim to understand the molecular mechanisms that regulate protein biogenesis and quality control pathways with approaches utilizing biochemistry, structural biology, and cell biology. Specific interests focus on processes that occur on ribosomes and at cellular membranes.
A major focus of my lab is to understand epigenetic regulation and its role in human diseases. Specifically, we are investigating how histone methylation is dynamically regulated as well as mechanisms involved in the recognition of combinatorial modifications occurring on histone tails that are important for chromatin regulation.
Our laboratory is centered on the molecular basis of cell differentiation and tissue development, using adipogenesis as a model system. We are also interested in the biochemical mechanisms of metabolic diseases relating to adipogenesis, especially obesity and insulin-resistant diabetes (NIDDM). In addition, we have a major interest in trying to alter cancer cell growth by stimulating pathways of terminal differentiation.
My research interests are focused on the molecular mechanisms that guide neuronal growth cones through the developing embryo to reach and select their appropriate synaptic targets.
