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.

We seek to understand how tissues and organs are shaped in the embryo and how principles of self-assembly can be applied to engineer tissues. Our experimental and theoretical approaches are multi-scale, ranging from super-resolution imaging and simulation of intracellular effectors to mesoscale analysis of bulk movements and biomechanics. Such multi-scale analysis is uncovering feedback circuits that make tissue assembly more robust even as structures become more complex.

Alexander DömlingLab Website
Alexander Dömling – Professor and Chair of Drug Design, University of Groningen, Netherlands
Ph.D., Multicomponent Reaction Chemistry, Technical University of Munich
Prof Alexander Dömling (Chair of Drug Design at the University of Groningen) devotes his academic life to the structure based design and discovery of bioactive compounds for difficult targets such as protein protein interactions. At the University of Pittsburgh he introduced the “google-like” and web-based technology ANCHOR.QUERY together with Carlos Camacho. ANCHOR.QUERY and the congeners NUCLEO.QUERY and TPP.QUERY can screen very large (billions) of virtual compounds in just seconds for pharmacophores and based on key interacting fragments, e.g. large amino acid side chains of amino acids (in PPIs) or nucleotides or the cofactor thiamine. Interestingly the resulting virtual hits can be instantaneously synthesized using convergent and fast multicomponent reaction chemistry (MCR) in order to test the virtually generated hypothesis. Another development are is the technology platform Drug Discover at the Speed of Sound (DDSoS). Here we introduce a fundamentally novel approach towards preclinical drug discovery and development by blending Instant Chemistry, nL dispensing, acoustic-MS, uHTS and artificial intelligence. The indication areas Alexander Dömling is interested in are cancer immunology, infectious diseases and metabolic disorders. He has published more than 150 scientific articles, reviews and patents. Additionally Alexander Dömling is a serial entrepreneur trying to make the expression “from bench to bedside” become true.

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.

Environmental changes that interest me are 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.

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.
