PHD PROGRAM RESEARCH INTEREST |
We are a quantitative genetics lab interested the relationship between genes and complex disease. Most of our work focuses on developing statistical and computational techniques for the design and analysis of genetic experiments in animal models. This includes, for example: Bayesian hierarchical modeling of gene by drug effects in crosses of inbred mouse strains; statistical methods for identifying quantitative trait loci (QTL) in a variety of experimental mouse populations (including the Collaborative Cross); computational methods for optimal design of studies on parent of origin effects; modeling of diet by gene by parentage interactions that affecting psychiatric disease; detection and estimation of genetic effects on phenotypic variability.

PHD PROGRAM RESEARCH INTEREST |
Our laboratory is focusing on developing and applying solution-state NMR methods, together with computational and biochemical approaches, to understand the molecular basis of nucleic acid functions that range from enzymatic catalysis to gene regulation. In particular, we aim to visualize, with atomic resolution, the entire dynamic processes of ribozyme catalysis, riboswitch-based gene regulation, and co-transciptional folding of mRNA. The principles deduced from these studies will provide atomic basis for rational manipulation of RNA catalysis and folding, and for de novo design of small molecules that target specific RNA signals. Research program in the laboratory provides diverse training opportunities in areas of spectroscopy, biophysics, structural biology, computational modeling, and biochemistry. |

PHD PROGRAM RESEARCH INTEREST |
My research aims to uncover the molecular aspects of protein aggregation diseases (also called PAD) which include neurodegenerative diseases (such as Alzheimer’s disease and Amyotrophic Lateral Sclerosis), myofibrillar myopathies (such as muscular dystrophies), as well as the formation of age-related cataracts. Although very distinct, these disorders share a common underlying pathogenic mechanism. Using a combination of biochemistry and in vitro approaches, cell biology, and primary cells / transgenic mouse models, we will investigate the post-translational modifications (PTMs) that drive these disease processes. Ultimately, this research will provide a platform for future drug discovery efforts against these devastating diseases. |

Research in the Hicks lab focuses on development and implementation of mass spectrometric approaches for protein characterization including post-translational modifications, as well as the identification of bioactive peptides/proteins from plants. Keywords: proteins / peptides, proteomics, PTM, enzymes, analytical chemistry, mass spectrometry, separations / chromatography, plants, algae. |
| Purvis, Jeremy WEBSITE PUBLICATIONS |
PHD PROGRAM RESEARCH INTEREST |
We study the behavior of individual cells with a specific focus on “irreversible” cell fate decisions such as apoptosis, senescence, and differentiation. Why do genetically identical cells choose different fates? How much are these decisions controlled by the cell itself and how much is influenced by its environment? We address these questions using a variety of experimental and computational approaches including time-lapse microscopy, single-molecule imaging, computational modeling, and machine learning. Our ultimate goal is to not only understand how cells make decisions under physiological conditions—but to discover how to manipulate these decisions to treat disease. |
| Tarantino, Lisa M. WEBSITE PUBLICATIONS |
PHD PROGRAM RESEARCH INTEREST |
The Tarantino lab studies addiction and anxiety-related behaviors in mouse models using forward genetic approaches. We are currently studying a chemically-induced mutation in a splice donor site that results in increased novelty- and cocaine-induced locomotor activity and prolonged stress response. We are using RNA-seq to identify splice variants in the brain that differ between mutant and wildtype animals. We are also using measures of initial sensitivity to cocaine in dozens of inbred mouse strains to understand the genetics, biology and pharmacokinetics of acute cocaine response and how initial sensitivity might be related to addiction. Finally, we have just started a project aimed at studying the effects of perinatal exposure to dietary deficiencies on anxiety, depression and stress behaviors in adult offspring. This study utilizes RNA-seq and a unique breeding design to identify parent of origin effects on behavior and gene expression in response to perinatal diet. |
| Cohen, Jessica WEBSITE PUBLICATIONS |
PHD PROGRAM RESEARCH INTEREST |
The Cohen Lab investigates how functional brain networks in humans interact and reconfigure when confronted with changing cognitive demands, when experiencing transformations across development, and when facing disruptions in healthy functioning due to disease. We are also interested in how this neural flexibility contributes to flexibility in control and the ability to learn, as well as the consequences of dysfunction in this flexibility. We use behavioral, neuroimaging, and clinical approaches taken from neuroscience, psychology, and mathematics to address our research questions. |
| Shiau, Celia WEBSITE PUBLICATIONS |
PHD PROGRAM RESEARCH INTEREST |
The Shiau Lab is integrating in vivo imaging, genetics, genome editing, functional genomics, bioinformatics, and cell biology to uncover and understand innate immune functions in development and disease. From single genes to individual cells to whole organism, we are using the vertebrate zebrafish model to reveal and connect mechanisms at multiple scales. Of particular interest are 1) the genetic regulation of macrophage activation to prevent inappropriate inflammatory and autoimmune conditions, and 2) how different tissue-resident macrophages impact vertebrate development and homeostasis particularly in the brain and gut, such as the role of microglia in brain development and animal behavior. |
| Phanstiel, Doug WEBSITE PUBLICATIONS |
PHD PROGRAM RESEARCH INTEREST |
It is estimated that less than 2% of the human genome codes for a functional protein. Scattered throughout the rest of the genome are regulatory regions that can exert control over genes hundreds of thousands of base pairs away through the formation of DNA loops. These loops regulate virtually all biological functions but play an especially critical role in cellular differentiation and human development. While this phenomenon has been known for thirty years or more, only a handful of such loops have been functionally characterized. In our lab we use a combination of cutting edge genomics (in situ Hi-C, ATAC-seq, ChIP-seq), proteomics, genome editing (CRISPR/Cas), and bioinformatics to characterize and functionally interrogate dynamic DNA looping during monocyte differentiation. We study this process both in both healthy cells and in the context of rheumatoid arthritis and our findings have broad implications for both cell biology as well as the diagnosis and treatment of human disease. |
