Isabella Alves

Isabella [National Mah Jongg League Scholar] was born and raised in Puyallup, Washington. She graduated from Pacific Lutheran University, Tacoma, with a BS in Biological Sciences with minors in Chemistry and Business Administration. Her motivation to pursue cancer research stems from her own health struggles, which sparked a strong interest in human health and biology from an early age. Over time, that interest has evolved into a deep intellectual curiosity about the molecular mechanisms of cancer. During her undergraduate studies, she had the opportunity to work as a summer intern in the laboratory of Christina M. Termini, PhD, where she investigated how inhibiting isoprenoid production impacts hematopoietic stem cell (HSC) maintenance, expansion, and survival. Her ultimate goal is to contribute meaningfully to improving patient outcomes by developing safe, accessible, and effective cancer treatments. Outside the lab, she enjoys being outdoors, cooking, dancing, and spending quality time with her family.

Longfu Xu, PhD

Project title
"Filming mechanochemical cycles of ring ATPase: Phi 29 DNA packaging motor as an example"

Many cancers develop when crucial “cellular machinery” malfunctions. One component of this machinery is the ring ATPase, which harnesses the energy from ATP to perform essential tasks such as maintaining protein homeostasis and ensuring genome stability—processes vital for preventing uncontrolled cell growth. Understanding precisely how these complex human ring ATPases operate and coordinate their actions remains a significant challenge. Dr. Xu’s [HHMI Fellow] research focuses on a mechanically similar, yet structurally simpler, ring ATPase found in the φ29 bacteriophage. By filming high-resolution “movies” of this viral ring ATPase in action using advanced single-molecule techniques, Dr. Xu aims to uncover the fundamental principles of its mechanochemical cycle. This will reveal, step-by-step, how it converts chemical energy into the precise mechanical forces and coordinated movements required to stabilize DNA. This work is relevant to a range of cancers where cellular ring ATPases are dysregulated, and the insights gained could pave the way for novel therapeutic strategies targeting these essential molecular machines. Dr. Xu received his PhD from Vrije Universiteit, Amsterdam, his MS from the University of Chinese Academy of Sciences, Beijing, and his BS from Northeast Agriculture University, Harbin.

Denis Torre, PhD

Project title
"Dissecting dynamic cellular responses to genetic perturbations using time-resolved single-cell CRISPR screens"

Genetic disturbances can disrupt normal cellular programs, promote unrestricted proliferation (i.e., tumor growth), and expose vulnerabilities that can be targeted therapeutically. However, how cells dynamically respond to such changes over time remains incompletely understood. Dr. Torre will use cutting-edge genetic tools, such as CRISPR and single-cell RNA sequencing, to study the precise sequence of molecular events triggered upon silencing of key regulators of cell identity and proliferation in human cells. By combining single-cell data with advanced statistical modeling, this work will reveal how gene perturbations dynamically alter cellular networks and drive survival or cell death, thus helping inform the development of novel cancer treatments. Dr. Torre received his PhD from the Icahn School of Medicine at Mount Sinai, New York, and his BS from the University of Trieste, Trieste.

Rebecca Pasquarelli, PhD

Project title
"Investigating novel mechanisms of tumor immune evasion"

In order to survive, cancer cells must evade or disable the immune system. Many cancers are caused by chronic infection with viruses that modulate the host cell by influencing gene expression to achieve this same goal. Dr. Pasquarelli [HHMI Fellow] is studying how viral proteins alter gene expression to create a tumor microenvironment that prevents the immune system from killing cancer cells. Since many viral proteins achieve this by changing the expression of secreted proteins, which can be therapeutically targeted, Dr. Pasquarelli is also exploring the effect of secreted proteins on tumor immune evasion. This work will deepen our understanding of how cancers evade the immune system and has the potential to uncover new targets for cancer treatment. Dr. Pasquarelli received her PhD from the University of California, Los Angeles, and her BS from Brown University, Providence.

Parker J. Nichols, PhD

Project title
"Elucidating the mechanism of inosine-dependent inhibition of RIG-I-like receptor filamentation and interferon signaling"

Cells have a built-in defense system that detects double-stranded RNA (dsRNA), a molecule often associated with viruses. Although this system evolved to fight microbial infections, activating it can also help the body recognize and attack cancer, especially when combined with treatments that make tumors easier for immune cells to detect. However, tumors can escape this immune pathway by producing high levels of a protein called ADAR, which edits dsRNA by changing one of its building blocks, adenosine, into inosine. These edits prevent the dsRNA from being recognized, allowing cancer cells to stay hidden even during treatment. Dr. Nichols’ [Merck Fellow] research aims to understand how these RNA changes block immune detection and to identify which RNA molecules are most likely to trigger an immune response. By uncovering how cancer cells use this editing process to escape detection, he hopes to support the development of better immunotherapy treatments. Dr. Nichols received his PhD from the University of Colorado, Anschutz Medical Campus, Aurora, and his BA from Lewis and Clark College, Portland.

Hannah R. S. Martin, PhD

Project title
"Investigating the neural mechanisms that drive skeletal pain"

“Bone-deep pain” is more than a metaphor. Bones and joints are constantly monitored by sensory neurons (nociceptors) that detect damage and trigger protective pain responses. However, in bone cancer and osteoarthritis, this pain can become chronic and debilitating—especially when the bone’s rich environment is colonized by migrating metastatic tumor cells originating in the prostate, breast, or lung. Dr. Martin’s [Connie and Bob Lurie Fellow] research aims to uncover how skeletal sensory neurons are activated and remodeled in these conditions. Using neurophysiology techniques, she is mapping how skeletal neurons respond to potential triggers and testing a new hypothesis: that these neurons not only detect tumors but also influence their growth. This work may uncover new strategies for treating chronic skeletal pain. Dr. Martin received her PhD from the University of Chicago, Chicago, and her BS from St. John’s University, New York.

Kate M. MacDonald, PhD

Project title
"Formation, excision and cytoplasmic export mechanisms for pathological R-loops"

Despite being necessary for life, gene expression is dangerous. It forces the double-stranded DNA helix to unwind and separate, so that one strand can be used as the template to synthesize an RNA molecule—the cousin of DNA that brings genes to life. This process leaves the opposite strand exposed and vulnerable to accidental damage and mutation, which can then cause cancer. Dr. MacDonald’s [Connie and Bob Lurie Fellow] work will systematically check various features of RNA molecules, looking for characteristics that cause an RNA sequence to aberrantly stabilize on its template DNA, prolonging the vulnerable exposure of the opposite DNA strand. Using a new kind of microscopic RNA imaging that she developed, she will find the cellular proteins responsible for removing pathologically stable RNA molecules from DNA. Uncovering the molecular features that promote gene expression-driven DNA damage will deepen our understanding of the origins and development of all cancers. Dr. MacDonald earned her PhD from the University of Toronto, Toronto, and her BS from the University of British Columbia, Vancouver.

Ling S. Loh, PhD

Project title
"Selfish persistence within a (super)organismal host"

In simple terms, cancer arises when some cells in our body stop cooperating with the rest and start growing uncontrollably, threatening the whole organism. This breakdown in cooperation is similar to how certain beetles (called myrmecophiles) infiltrate ant colonies and selfishly use their resources, acting like a “cheater” in a cooperative society. Both cancer cells in healthy tissue and these beetle invaders in ant colonies represent a failure of cooperation, whether among cells in an organism or individuals in a colony. Ant colonies, like multicellular organisms, rely on strict controls to function properly, and when those controls are bypassed, the whole system is at risk. By recreating a key “cheating” trait in beetles—disabling their surface chemical signals to let them sneak into ant colonies—the project aims to reveal universal principles about how cooperation breaks down and how systems might evolve defenses against such threats. These insights could help to understand the fundamental properties of cancer and how to design better strategies to stop it. Dr. Loh [Sijbrandij Foundation Fellow] received her PhD from George Washington University, Washington D.C., and her BS from National University of Singapore, Singapore.

Jane E. Lodwick, PhD

Project title
"Revealing structure and function of an anomalous bacterial secretion system throughout the host cell"

Many bacteria naturally colonize tumors, inspiring an emerging class of microbial therapeutics that can be modified to specifically deliver drugs into cancer tissue. In one promising drug delivery strategy, bacteria are engineered to efficiently transfer bespoke molecular cargo into human cells through bacterial membrane channels called secretion systems. Although many kinds of bacterial secretion systems exist, few have been studied well enough to be used in delivery platforms. Dr. Lodwick [National Mah Jongg League Fellow] plans to investigate the structure and function of a specific secretion system in a bacterium called Rickettsia parkeri. Understanding how and when its components assemble into a cargo delivery machine may aid the development of new bacteria-based cancer therapies. Dr. Lodwick received her PhD and MS from the University of Chicago, Chicago, and her BA from Wellesley College, Wellesley.
