Three Visiting International Researchers Also Receive Awards

Twelve scientists at Columbia University Vagelos College of Physicians and Surgeons have received awards from the Schaefer Research Scholars Program, made possible through a bequest from Dr. Ludwig Schaefer.  

This year, the annual awards were granted to distinguished VP&S scientists exploring new directions in their research or proposing research designed to reveal new aspects of human physiology. Each award consists of up to $100,000 in direct research support. 

Three visiting scientists also received awards, which are designed to foster new or existing collaborations with VP&S colleagues.

Eunhee Choi, PhD

Assistant Professor of Pathology & Cell Biology

Recalibrating Nutrient and Growth Signaling During Human Aging

This project will investigate how growth-promoting pathways that are essential early in life are adaptively reconfigured during aging to preserve cellular and tissue resilience. These studies may uncover fundamental mechanisms of aging and identify new strategies to promote healthy metabolic function during aging.


 

Oliver Clarke, PhD, associate professor, Columbia University

Oliver Clarke, PhD

Associate Professor of Physiology and Cellular Biophysics (in Anesthesiology and in the Irving Institute for Clinical and Translational Research)

Designing a toolkit of isoform-specific mini-protein binders for tagless labeling and isolation of ankyrin ion channel complexes

The goal of Oliver Clarke’s proposal is to computationally design and validate miniprotein binders against neuronal and muscle ankyrins, in order to facilitate labeling, isolation and functional characterization of ankyrin-ion channel interactions, disruption of which is associated with neuropsychatric disorders (for neuronal complexes) and hereditary cardiac arrhythmias (for cardiac complexes).

Manu Johny, PhD

Assistant Professor of Physiology & Cell Biology

Tuning the Leak: Molecular Mechanisms and Targeted Therapeutics for NALCN Channelopathies

Gain-of-function variants in the sodium leak channel (NALCN) cause excessive sodium influx and underlie a rare, severe neurodevelopmental disorder called CLIFAHDD (Congenital contractures of the Limbs and Face, Hypotonia, and Developmental Delay). This project seeks to identify the cellular and molecular mechanisms governing NALCN function and to develop novel protein-based approaches to downregulate NALCN currents, laying the groundwork for future therapeutics.


 

Shawn Liu, PhD, Columbia University Vagelos College of Physicians and Surgeons

Shawn Liu, PhD

Joan and Paul Marks, MD '49 Assistant Professor of Physiology and Cellular Biophysics

Mutation-Agnostic Silencing of Pathological Alleles by CRISPR-IMPRINT

Shawn Liu and his team are developing CRISPR-IMPRINT, a novel epigenome editing platform that can selectively silence disease-causing gene copies in patients with dominant genetic disorders, without altering the healthy copy, aiming to create a mutation-agnostic therapeutic strategy capable of treating a broad spectrum of patients with a single molecular design.


 

 

Nikhil Sharma, PhD, assistant professor of molecular therapeutics, Columbia University

Nikhil Sharma, PhD

Assistant Professor of Molecular Pharmacology & Therapeutics

The role of the intestinal nervous system in the neurodegenerative process

This project will look to determine whether the enteric nervous system, the neurons that live inside the walls of the intestine, are an origin for neurodegenerative disorders of the brain. 


 

Kazuki Sugahara, assistant professor of surgery, Columbia University

Kazuki Sugahara, MD, PhD

Assistant Professor of Surgery

An Antigen-Agnostic Screening Platform for Novel CAR-T Cells

Kazuki Sugahara will develop a novel platform to identify effective CAR-T constructs for cancer therapy. By eliminating the need to pre-identify tumor-specific antigens, the approach could help overcome a major limitation of CAR-T therapy: the scarcity of targetable antigens.


 

Alison Taylor, PhD, assistant professor of pathology, Columbia University

Alison Taylor, PhD

Florence Irving Assistant Professor of Pathology and Cell Biology (in the Herbert Irving Comprehensive Cancer Center)

Aneuploidy associated tissue-specific consequences in cancer

Alison Taylor’s research program focuses on using functional genomics to understand the consequences of individual aneusomies in squamous cell carcinoma. As part of this award, and motivated by her lab's recent findings of tissue-specific aneuploidy breakpoints and gene expression patterns, she will investigate how aneuploidy influences tumor development in a tissue-specific manner. 


 

Kelley Yan, MD, PhD, assistant professor of medicine, Columbia University

Kelley Yan, MD, PhD

Warner-Lambert Assistant Professor of Medicine (in Columbia Center for Human Development) and Assistant Professor of Genetics and Development

Limbal stem cells in corneal epithelial homeostasis and regeneration

Kelley Yan’s lab focuses on adult stem cells in the gut that regenerate the gut lining. In this project, she will apply some of their findings and approaches to the eye by studying how the corneal epithelium regenerates, toward the ultimate goal of enhancing healing of corneal injuries.


 

Dian Yan, PhD, assistant professor of molecular pharmacology, Columbia University

Dian Yang, PhD

Assistant Professor of Molecular Pharmacology & Therapeutics

CellLog: Non-Destructive Longitudinal Tracking of Cellular History

This proposal aims to develop a novel system to track and reconstruct cell state transitions over time.


 

Shan Zha, MD, PhD, professor of pediatrics, Columbia University

Shan Zha, MD, PhD

James A. Wolff Professor of Pediatrics, Pathology & Cell Biology, and Microbiology & Immunology (in the Institute for Cancer Genetics and Herbert Irving Comprehensive Cancer Center)

Ku as a Primate- and Human-Specific Master Regulator of RNA Homeostasis: Implications for Cancer and Neurodegeneration

With this support, the Zha lab will investigate how the Ku protein, long known for its role in DNA repair, also regulates RNA processing and related cellular stress responses in primate cells. These results will shed light on the evolutionary adaptation that enabled primates to tolerate massive Alu expansion and harness the resulting increase in genome and transcriptome complexity.

Chaolin Zhang, PhD

Professor of Systems Biology and Biochemistry and Molecular Biophysics (in the Motor Neuron Center)

From innate immunity to neurodegeneration: mapping the RNA structure regulome of dsRBPs

In this project, Chaolin Zhang and his team will develop next-generation technologies for mapping the RNA structure regulome of double-stranded RNA-binding proteins, which has the potential to transform studies of RNA regulation in antiviral immunity, neurodevelopmental disorders, and neurodegenerative disease.

Hanrui Zhang, PhD

Assistant Professor of Medical Sciences (in Medicine)

Enhancing macrophage efferocytosis to mitigate autoimmunity and inflammaging

This award will support research exploring how enhanced macrophage clearance of dying cells may restore immune balance and reduce chronic inflammation, with the goal of advancing new therapeutic strategies for autoimmunity and age-associated chronic inflammation.

Targeting Microtubule Remodeling in Microglia: A Novel Approach to Monitoring and Modulating Neuroinflammation in Neurodegenerative Disease

Host: Francesca Bartolini, PhD (Pathology & Cell Biology)

This project explores a novel paradigm in neuroinflammatory and neurodegenerative disease research by investigating how remodeling of the microtubule cytoskeleton in microglia regulates inflammatory responses, using advanced human stem cell-derived models.
