Gregory Alushin
Cytoskeletal structure and cell mechanics

Greg Alushin is an Assistant Professor and Head of the Laboratory of Structural Biophysics and Mechanobiology at The Rockefeller University. He received his PhD in Biophysics from the University of California, Berkeley in 2012, where he worked with Eva Nogales to visualize structural transitions in tubulin underlying microtubule dynamic instability and protein complexes which form attachments between chromosomes and microtubules during mitosis. After a brief postdoc with Clare Waterman at the National Institutes of Health focused on the cell biology of the actin cytoskeleton and mechanical signal transduction, Greg established his lab there in 2013 as a faculty fellow before moving to Rockefeller in 2017. The Alushin lab uses cell biological, biophysical, and structural approaches to study how mechanical forces regulate cytoskeletal filaments and their partners to mediate cellular force sensing.

Çagla Eroglu
Astrocyte-neuronal communication and synaptic connectivity

Çagla received her PhD from the European Molecular Biology Laboratories and University of Heidelberg, Germany, where she investigated the structure function relationship of metabotropic glutamate receptors. She was a postdoc at Stanford University Medical Center in the lab of Ben Barres, where she started her work on the molecular mechanisms that underlie astrocyte–neuron communication that controls synapse formation. In 2008, Çagla joined the Duke University School of Medicine where she is now an associate professor of Cell Biology, and a Howard Hughes Medical Institute investigator. Her lab investigates the cellular and molecular mechanisms that underlie synaptic connectivity in the central nervous system. They view astrocytes as an integral part of the synapse with roles in synapse development, function, and plasticity. Their research revealed important molecular and cellular mechanisms that mediate astrocyte–neuron signaling, which controls synapse formation and maturation. Currently, they are continuing to investigate the function of astrocyte–neuron communication in the normal mammalian brain and how problems in astrocyte–neuron communication contribute to the pathophysiology of neurodevelopmental disorders and neurodegeneration.

Andrew Ewald
Epithelial cell biology, cell adhesion, cell migration, cancer invasion and metastasis

Andrew Ewald is Professor and Director of Cell Biology in the Johns Hopkins Medical School and Co-Leader of the Cancer Invasion and Metastasis Program in the Sidney Kimmel Comprehensive Cancer Center. He earned his BS in Physics from Haverford College and his PhD in Biochemistry and Molecular Biophysics from Caltech, working with Scott Fraser on imaging cell movements in early embryos. He then conducted postdoctoral research with Zena Werb at UCSF, focusing on epithelial morphogenesis and breast cancer invasion. He joined the Hopkins faculty in 2008 and his laboratory uses a combination of 3D culture, molecular genetics, bioinformatics, and engineering analysis to identify candidate molecular drivers of metastatic processes. They then validate the functional requirement for these regulators in murine cancer models and patient tumor tissue. He uses these tools to understand how cancer cells escape the primary tumor, access and survive within the vasculature, evade the immune system, and establish lethal tumors in distant organs.

Laura Lackner
Organelle positioning and inter-organelle contacts

Laura Lackner is an Associate Professor in the Department of Molecular Biosciences at Northwestern University. She is interested in how spatial and dynamic organization within cells is achieved. As a model for intracellular organization, she studies the mechanisms that shape and position mitochondria. Laura received her BS in Life Science Chemistry from John Carroll University and her PhD in Molecular Biology from Case Western Reserve University, where she worked with Piet de Boer on the mechanism of division site selection in Escherichia coli. She went on to do her postdoctoral work with Jodi Nunnari at the University of California, Davis. In Jodi’s lab, she studied the mechanisms of mitochondrial division and positioning. She started her own laboratory in 2013, and her group is working to understand fundamental mechanisms used by cells to position mitochondria as well as form and regulate interorganelle contacts.

Michael Lazarou
Regulation of protein trafficking

Michael was awarded his PhD from La Trobe University with Mike Ryan, studying the assembly of mitochondrial protein complexes and how they break down in energy generation disorders. He conducted his post-doctoral studies in Richard Youle’s laboratory at the National Institutes of Health, focusing on the Parkinson's disease proteins PINK1 and Parkin, and their role in maintaining mitochondrial health through mitophagy. The work led to Michael receiving the 2013 ASBMB Boomerang Award. He joined the Monash Biomedicine Discovery Institute (Monash University, Australia) in June 2014 as head of the Autophagy and Mitochondrial Quality Control laboratory. Michael was an Australian Research Council Future Fellow (2016–2019) and is currently Associate Professor at the Walter and Eliza Hall Research Institute (joined in 2022), where he is co-affiliated with Monash University. His lab uses multiple imaging modalities, including volumetric electron microscopy, combined with biochemistry, to understand the mechanisms of PINK1 and Parkin mitophagy, mitochondrial quality control, and the intricate cell biology behind autophagy.

Kassandra Ori-McKenney
Microtubule cytoskeletal dynamics and microtubule-based transport

Kassandra Ori-McKenney is an Associate Professor of Molecular and Cellular Biology at the University of California, Davis. Kassandra performed her graduate work on the microtubule motor, cytoplasmic dynein in the lab of Richard Vallee at Columbia University. After receiving her PhD, she pursued her postdoctoral work with Yuh Nung Jan at the University of California, San Francisco, where she focused on the organization and regulation of the microtubule cytoskeleton during neuronal development. In January 2016, she joined the University of California, Davis, and her lab uses a combination of biochemical, single-molecule, and cell biology techniques to study how microtubule-associated proteins contribute to cellular health. Kassandra has received the March of Dimes Basil O’Connor Award, the Simons Foundation Pilot Grant, the Pew Biomedical Scholar Award, and a National Institutes of Health MIRA Grant.

Elçin Ünal
Regulation of meiotic differentiation

Elçin Ünal is an associate professor in the Molecular and Cell Biology Department at the University of California, Berkeley. Ünal received her PhD from Johns Hopkins University with Doug Koshland, where she studied the regulation and function of cohesin complex during DNA damage response. For her postdoctoral studies with Angelika Amon at the Massachusetts Institute of Technology, Ünal continued to use budding yeast as a model system, where she discovered that gametes produced from aged yeast cells are born “young,” providing the first evidence for natural resetting of aging clock. Ünal’s group studies various aspects of meiotic differentiation ranging from transcriptional control to organelle remodeling with the goal of understanding how gamete formation promotes cellular rejuvenation, and how the processes that ultimately drive cellular rejuvenation are controlled by the meiotic transcriptional program.
