Yiyin Erin Chen, MD, PhD

Dr. Chen’s research aims to harness a common skin-colonizing bacterium, present on all our skin, to train the immune system to attack cancer without causing infection or inflammation. This process is known to occur—notably, across an intact skin barrier—but its mechanism is not well understood. Dr. Chen is investigating which skin cells sense these bacteria and transmit the signal to immune cells, and why the immune cells that respond are so effective at killing cancer. Ultimately, she intends to develop a new type of cancer vaccine using engineered skin bacteria to activate immune cells to effectively target and destroy tumors. While the project’s current focus is melanoma, the goal is to apply this therapeutic approach across cancer types.

Hui (Vivian) Chiu, PhD

Fatigue is the most common symptom experienced by patients with cancer or undergoing cancer treatment. While chronic inflammation and hormonal imbalance have been suggested as possible causes, the roots of cancer-related fatigue remain unclear and thus we lack effective treatments. Dr. Chiu [HHMI Fellow] seeks to illuminate the physiological basis of fatigue using interdisciplinary approaches that combine the strengths of neuroscience, immunology, and computational biology. Through the lens of brain-body interactions, Dr. Chiu aims to identify key molecular and cellular components of fatigue with the goal of improving treatments for cancer and other severe diseases, such as long COVID. Dr. Chiu received her PhD from the California Institute of Technology, Pasadena and her MS and BS from the National Taiwan University, Taiwan.

Junhong Choi, PhD

Dr. Choi develops a technology called “Molecular recording”, which allows the recording of cellular events and their lineage information into each cell’s genome. These innovative tools are critical for understanding the development of individual cells, both in normal developmental processes and in diseases like cancer. Recently, Dr. Choi has successfully demonstrated this technology by engineering human cancer cells to record their lineage or signaling events in a culture dish (“in vitro”) using CRISPR-based genome editing methods. Moving forward, Dr. Choi plans to further develop these methods to study cancer development. The goal is to uncover how specific characteristics of cancer cells emerge, ultimately identifying new targets for treatment.

Edward M. C. Courvan, PhD

Macrophages are specialized immune cells responsible for “eating” harmful cells, presenting antigens to T cells, and initiating inflammation by releasing signaling molecules called cytokines. Macrophages could potentially be activated to attack tumor cells, but for reasons that are currently unclear, they instead signal for the tumor to grow faster and become more invasive. Dr. Courvan is investigating how macrophages respond to the low-oxygen environment inside tumors, and specifically how they regulate gene expression through post-transcriptional mechanisms in low-oxygen conditions. With this research, he hopes to uncover new ways to leverage the body's immune system against cancerous cells. Dr. Courvan received his PhD from Yale University and his BS from the University of Connecticut.

Antonio Cuevas-Navarro, PhD

Dr. Cuevas-Navarro’s [Berger Foundation Fellow] research project focuses on targeting mutations in the RAS genes (HRAS, NRAS, and KRAS), present in about 30% of cancer patients and notorious for driving aggressive tumor growth. Dr. Cuevas-Navarro aims to mitigate these mutations’ effects by using pharmacological agents to enhance a biochemical process that regulates RAS proteins. His project will investigate the mechanism of action of these compounds and assess their effectiveness in patient-derived cancer models. This research has the potential to expand treatment options across various cancer types, including those where current treatments are limited. Dr. Cuevas-Navarro received his PhD from University of California, San Francisco and his BS from University of California, Davis.

John Devany, PhD

T cell therapies have led to promising results in treating blood cancers, but new approaches are required to translate these results to solid tumors. In solid tumors, T cells face unique challenges in the tumor microenvironment (TME), which limits the persistence and efficacy of adoptive T cell therapies. In T cell lymphomas (TCLs), tumor cells overcome many of the same challenges through acquired mutations. Fueled by natural selection, tumor mutations produce novel and elegant solutions to address T cell deficits in the TME. Understanding that these modifications may be superior to current bioengineering capabilities, Dr. Devany [Bakewell Foundation Fellow] plans to introduce gain-of-function mutations into therapeutic T cells to grant them the ability to survive, proliferate, and function in the TME. He will determine how each mutation restores different aspects of T cell function, allowing for the design of combinations of mutations that act synergistically. His results will aid in the development of next-generation T cell therapies to cure solid tumors. Dr. Devany received his PhD from University of Chicago, Chicago and his BS from University of California, Santa Barbara.

Mingjian Du, PhD

Global increases in metabolic syndrome, obesity, and diabetes are likely related to the overconsumption of hyper-palatable, cheap, ultra-processed food containing high amounts of added sugar and fat. Intriguingly, the vagus nerve has been discovered as the key conduit relaying information about sugar or fat ingestion from the gut to the brain, where a preference for sugar or fat is then developed and reinforced. Dr. Du [HHMI Fellow] aims to understand how the neurons are organized in the gut-brain vagal axis to sense sugar and fat, and to identify and characterize the neural circuits downstream of the gut-brain vagal axis that produce an insatiable appetite for sugar and fat. Understanding the basic biology of the gut-brain axis can provide important insights and strategies to help combat overconsumption of highly processed foods rich in sugar and fat, which may contribute to lowering the risk of metabolic diseases and cancer. Dr. Du received his PhD from The University of Texas Southwestern Medical Center, Dallas and his BS from the Tsinghua University, Beijing.

Courtney Ellison, PhD

Courtney Ellison, PhD [Marilyn and Scott Urdang Breakthrough Scientist] is investigating how single bacterial cells join together to form complex, multicellular structures called biofilms. Biofilms protect bacterial cells from antibiotics and antimicrobial agents, making them difficult to eliminate. Some biofilm-forming species may cause certain cancers, and biofilms of infectious bacteria threaten immunocompromised patients such as those undergoing chemotherapy. Dr. Ellison focuses on bacterial appendages called type IV pili that play a crucial role in biofilm formation. Understanding the role of pili and their contribution to biofilm progression may lead to novel therapies to eliminate biofilms.

Teng Gao, PhD

Hematopoietic stem cells, which are found in the bone marrow and give rise to all other blood cells, maintain lifelong blood production and immune function. Due to their remarkable ability to regenerate the entire blood system, medical uses of HSCs have provided cures for many previously incurable diseases, including blood cancers. However, several unanswered questions limit our ability to full harness their therapeutic potential for cancer treatment. What regulates HSC regeneration? Why does their function decline with age? How does HSC behavior vary in healthy individuals? Using cutting-edge single-cell analyses and computational biology, Dr. Gao [HHMI Fellow] aims to identify the molecular and cellular factors involved in HSC regeneration, as well as possible targets for enhancing their regenerative potential. This work could enable significant improvements in stem cell-based therapies for cancer treatment. Dr. Gao received his PhD from Harvard University, Cambridge and his BS from Washington University, St. Louis.

Hasreet K. Gill, PhD

Dr. Gill [HHMI Fellow] is studying cell-cell communication via quorum sensing in developing biofilms. Biofilms are communities of bacteria that take on a three-dimensional structure and often develop striking visual features like wrinkles. Resident bacteria exploit this complexity to resist antimicrobial treatments and cause disease, particularly in healthcare settings, where biofilms pose serious threats to immunocompromised chemotherapy patients. Quorum sensing is the process by which bacteria orchestrate collective behaviors, including the assembly and dissolution of biofilm communities. Using quantitative microscopy at single-cell resolution, Dr. Gill is investigating how these signals between bacteria result in the construction of spectacular 3D biofilms at the air-liquid interface. A deeper understanding of how bacteria thrive in dynamic environments will contribute to new strategies to combat infections, which will positively impact treatments for all cancer types. Dr. Gill received her PhD from Harvard University, Cambridge and her BS from Drexel University, Philadelphia.
