Our group develops computational methods for understanding the dynamics, interactions and conservation of complex biological systems. As new high-throughput biological data sources become available, they hold the promise of revolutionizing molecular biology by providing a large-scale view of cellular activity. However, each type of data is noisy, contains many missing values and only measures a single aspect of cellular activity. Our computational focus is on methods for large scale data integration. We primarily rely on machine learning and statistical methods. Most of our work is carried out in close collaboration with experimentalists. Many computational tools we develop are available and widely used.

My research addresses how gene expression programs change, leading to changes to cellular identity. In multicellular organisms, the genetic instructions that guide the initial stages of embryonic development are inherited from the egg as RNA. When the embryonic genome becomes active, new RNAs are transcribed, while maternally provided RNAs are destroyed. During this “maternal-to-zygotic transition,” the embryo is effectively reprogrammed from an oocyte identity to pluripotency.

My research aims to understand the mechanisms of collective behavior and variability in bacterial cultures and their effect on the response of bacteria to changes in the environment. By studying the changes in the behavior of bacteria as a function of their concentration, I am able to detect some of the collective mechanisms that govern the bacterial behavior and allow them to better endure environmental stress (e.g. temperature and chemical). I utilize various optical microscopy techniques to observe the swimming pattern of bacteria under different conditions. As for the expression level of proteins, proteins of interest are labeled with fluorescent markers and the expression level is measured using fluorescence microscopy or flow cytometry.

Dr. Vodovotz’s research interests include the biology of acute inflammation in shock states (e.g. septic and hemorrhagic shock) as well as in chronic diseases and wound healing. He is also interested in the cross-regulation of the inducible nitric oxide synthase and the cytokine transforming growth factor-b1 in various disease states, including malaria infection, cancer, sepsis, and neurodegenerative diseases. His main current area of interest revolves around the use of mathematical modeling to unify and gain insight into the plethora of biological interactions that characterize these inflammatory conditions.

The Wells’ Lab research program, in close collaboration with its research partners, aims to understand cell migration in terms of how motility processes are regulated, and understand how this regulation of migration plays a role in physiologic and pathologic situations.

Xie’s group focuses on development of diseases-specific chemogenomics knowledgebase, an integrated platform of “Big Data to Knowledge” target identification and system pharmacology for drug discovery translational research. The innovation includes GPU-accelerated cloud computing machine-learning TargetHunter programs for drug target identification and system pharmacology. His lab was the first discovered/patented INK4C-targeting small molecule inhibitors for hematopoietic stem cell expansion (Nature Comm 2015), and was the first discovered/patented p62ZZ chemical inhibitors for multiple myeloma (Nature Leukemia 2015) .

Research: Computational Study of Protein Binding, Allostery, and Molecular Machines. Molecular-level biology is inherently dynamic. The Zuckerman group pursues ensembles of protein structures and pathways of conformational change that play a key role in binding, allostery and molecular machines. The group has been active in developing scale-free “weighted ensemble” (WE) software, which is now in use around the world. Zuckerman and colleagues developed WE methods for sampling steady-state and equilibrium conditions that have been applied to all-atom protein binding and to highly complex systems biology models of cell signaling.
