Cancer is a complex disease that is an aberration of our own tissues, but it still obeys fundamental biological rules. Our greatest challenge in the clinic is the emergence of resistance to our therapies, a process which is governed by Darwinian evolution. Using a suite of mathematical and experimental models, my laboratory seeks to deconvolute the complexity of the evolutionary process into fundamental principles. We aim to use this knowledge to then curtail the evolutionary process to increase the efficacy of targeted therapies and radiation. This same knowledge can be further harnessed to understand the differences in disease progression and therapy response on a personalized basis, so that the right treatment can be given to the right patient at the right time.
Our mission is to understand how cancers acquire resistance to targeted biological agents and radiation, and how pathogens evolve antibiotic resistance, and to harness this knowledge to design better therapeutic strategies for our patients.

Researchers from Cleveland Clinic, Case Western Reserve University School of Medicine and Moffitt Cancer Center have found that the genomic-adjusted radiation dose (GARD) may be used to personalize radiotherapy to maximize treatment efficacy among patients with cancer.
Kyle Card, PhD, a postdoctoral fellow in the Department of Translational Hematology & Oncology Research, has been named a Hanna Gray Fellow by the prestigious Howard Hughes Medical Institute (HHMI). The fellowship—which supports early career researchers and celebrates the importance of diversity in biomedical science—will help support Dr. Card’s postdoctoral work and provide start-up funds for his own laboratory, totaling roughly $1.4 million over eight years.
Clinical trials in lung cancer over the decades have determined an optimal “one size fits all” dosing scheme for patients treated with radiation therapy, but new research now shows this is not as biologically accurate as once believed. A new technology using tumor genomics to personalize radiation dosing demonstrates that the standard of care approach may be suboptimal for up to 75% of lung cancer patients.
Published in Nature Physics, findings from a new study co-led by Cleveland Clinic and Case Western Reserve University teams show for the first time how ideas from quantum physics can help develop novel drug interventions for bacterial infections and cancer.
Jacob Scott, MD, DPhil, Department of Translational Hematology and Oncology Research, recently received a five-year, $2.8M grant from the National Cancer Institute, part of the National Institutes of Health, to study how ecological and evolutionary mechanisms contribute to lung cancer development and progression, and how the interplay between these mechanisms may provide novel treatment insights.
Despite rapid advances in targeted therapies for cancer, tumors commonly develop resistance to treatment. When resistance emerges, tumor cells continue to grow unchecked, despite all attempts to slow the progression of the cancer. While mutations in cancer cells significantly affect drug sensitivity, it is increasingly recognized that ecological interactions between cells can also play a role.
Why Unrelated Diseases Follow the Same Incubation Pattern: Lessons from Evolutionary Dynamics, Statistics
When graphed, the incubation periods of many diseases, ranging from polio to measles to leukemia, have the same shape; they are skewed to the right. This means that when incubation periods, or time from pathogen exposure to symptomatic illness, and number of new disease cases in a population are plotted on the x- and y-axes, respectively, the peak of the curve falls on the left side of the graph, with a long tail on the right.
