About Rosemary Braun
Rosemary Braun is a computational biologist with an interest in the development of methods for integrative, systems-level analysis of high-dimensional ("big") *omic data.

Dr. Braun is an Assistant Professor of Biostatistics (Feinberg School of Medicine) and Engineering Sciences & Applied Mathematics at Northwestern University.
Title: Lively Networks
Many systems -- including living cells -- exhibit collective behaviors that emerge from complex networks of many interacting processes. What can the "wiring diagram" of those interactions tell us about the dynamics of the system, and can we deduce the underlying network from the collective dynamics? In this talk, I will discuss what we can learn about the dynamics of interacting systems from the topology of the underlying network of interactions. I will introduce the formalisms of spectral graph theory and network filtration, and illustrate how these approaches can help us model how living systems respond and adapt to perturbations.
Title: Seeing the forest and the trees: multi-scale approaches for analyzing cancer omics data.
Advances in high-throughput "*omic" assays now make it possible to the molecular state of a sample in genome-wide detail, providing unprecedented opportunity to investigate disease mechanisms by simultaneously profiling thousands molecular markers per sample. To date, however, most analyses of *omic data consider each marker independently and treat regulatory pathways as a "sum of their parts." By neglecting the network of interactions, such approaches can miss crucial multi--gene effects associated with disease. This talk will present some recent techniques to incorporate pathway information into the analysis of high--dimensional *omic data. By analyzing data at the systems level, the methods enable us to integrate disparate types of *omic data, make inferences about disease mechanisms, and distinguish sets of cumulatively deleterious alterations from those that compensate one-another to preserve the overall function of a pathway. We will show how these analyses can overcome the high variability of *omics data to yield results that are more reproducible across studies, and demonstrate how these methods can be used to identify novel therapeutic and diagnostic targets.

Control of Cell Fraction and Population Recovery during Tissue Regeneration in Stem Cell Lineages
Multicellular tissues are continually turning over, and homeostasis is maintained through regulated proliferation and differentiation of stem cells and progenitors. Following tissue injury, a dramatic increase in cell proliferation is commonly observed, resulting in rapid restoration of tissue size. This regulation is thought to occur via multiple feedback loops acting on cell self-renewal or differentiation. Prior modeling studies of the cell lineage system have suggested that loss of homeostasis and initiation of tumorigenesis can be contributed to the loss of control of these processes, and the rate of symmetric versus asymmetric division of the stem cells may also be altered.
Here, we compare three variants of hierarchical stem cell lineage tissue models with different combinations of negative feedbacks and use sensitivity analysis to examine what are the possible strategies for the cells to achieve certain performance objectives. Our results suggest that multiple negative feedback loops must be present in the stem cell lineage the fractions of stem cells to differentiated cells in the total population as robust as possible to variations in cell division parameters, and to minimize the time for tissue recovery in a non-oscillatory manner. When one of these negative feedback loops on stem cell division been knocked out, most of the stem cell lineage population will be in the form of stem cells, suggestive of "precancerous" tissue. Furthermore, modeling suggests that positive feedback loops in stem cell homeostasis may also be required. We contrast and compare the differences between deterministic and stochastic versions of the models.

The biology of hematopoietic stem and progenitor cells and the process of primitive hematopoiesis
We will discuss the process of primitive hematopoiesis, including the biology of hematopoietic stem and progenitor cells (HSPCs). We will review experimental methods to define HSPCs and their properties including quiescence, proliferation and differentiation rates. We will explore the current state of knowledge regarding how environmental stresses such as infection and inflammation perturb these properties. We will describe lineage tracing and bar-coding methodologies to study such perturbations. Finally, we will discuss how changes in HSPC populations contribute to clonal hematopoiesis and the potential contributions of infection and inflammation to leukemic transformation. This will include a basic discussion of leukemia, leukemic stem cells, and genetic basis of cancer.

Multi-scale modeling of paracrine PDGF-driven glioma growth and invasion
The most common primary brain tumor in adults, glioblastoma claims thousands of lives each year. It is a notoriously aggressive and invasive disease, and despite efforts to improve survival rates, the standard of care has remained unchanged for more than a decade. Platelet¬–derived growth factor (PDGF) is often over–expressed in gliomas, where it can drive tumor growth via autocrine and paracrine stimulation of PDGF receptor (PDGFR)–expressing glioma cells, as well as paracrine recruitment of non–neoplastic oligodendroglial progenitor cells (OPCs), which also express PDGFRs. Constructing multi-scale mechanistic mathematical models allows us to better examine the effects of paracrine PDGF signaling on glioma growth. Model simulations show that increased PDGF signaling can increase growth rates and alter the distribution of glioma cells infiltrating adjacent normal brain tissue. While the use of PDGF inhibitors has remained largely unsuccessful at improving patient outcomes in glioblastoma, this may be due to inadequate targeting of these agents to the best candidates. By incorporating different treatment simulations in our model, we show that PDGF inhibition results in decreased OPC recruitment, which leads to slower growing, but more diffusely infiltrating tumors.

Modern experimental advances have made it possible to measure DNA, RNA, and protein dynamics at the level of single molecules in single cells. These discrete data are often noisy, but they can be highly informative when combined with advanced computational analyses. I will present our recent advances to integrate discrete stochastic models with different single-cell assays. I will introduce modern experiments that are used to quantify mRNA and protein dynamics at single-molecule resolution. Next, we will derive strict bounds on the likelihood that observed single-cell data come from hypothesized models, and we will show how these bounds can be used to reduce computational efforts with no sacrifice to accuracy or precision. Then we will explore new computational approaches to design optimal single-cell experiments that maximize the expected information contained within an experiment. We will illustrate the integration of these experimental and computational tools to build predictive models for mechanistic biochemical processes in yeast and human cells, including spatiotemporal cell-signaling, single-gene transcription activation, nascent mRNA elongation, mRNA transport, mRNA-translation activation, sequence-dependent nascent protein elongation, and viral frameshifting.

Students will learn how to:
- Formulate the CME for various models of gene regulation.
- Solve the FSP approximation for the CME for transient times.
- Understand the use of the FSP to compute first passage times and decision probabilities for non-linear, and non-stationary processes.
- Compute the likelihood that measured data has come from a given FSP model.
- Maximize that likelihood using gradient and non-gradient based methods.
- Use MCMC to quantify parameter space around the maximum likelihood estimate.
- Use the model and FSP analysis to perform parametric sensitivity analysis.
- Use the FSP to compute the Fisher Information Matrix to quantify an experiment design’s capability to resolve key model parameters.
- Explore and explain how different experiments are expected to result in more or less information about model mechanisms and parameters.
Students are STRONGLY encouraged to think about their own projects and data when we decide which models to use for illustration of the above topics. Those interested to work on these projects and who would like to explore models tailored to their specific interests should send their research posters to Brian Munsky (email@example.com) during the first week of the qbSS program.

Tools for modeling optimal treatment schedules to delay cancer progression
Acquired drug resistance is an obstacle for the treatment of cancer. Throughout a tumor’s life, the possibility of genetic or epigenetic alterations may lead to a subclone resistant to the therapy provided. In some cases, additional therapies are possible to continue treatment. However, it’s been shown through modeling that resistance and tumor progression can be delayed by altering the schedule making use of pharmacokinetic parameters and tumor growth data to create an optimal dosing schedule where the drug concentrations may be under the maximum tolerated dose which is typically administered. We will explore the background tools used to create optimal dosing schedules which typically rely on time-inhomogeneous branching process models of growth and methods for elucidating data that can inform these models. An overview of topics will include the following for single drug and combination models:
- Quick review of simulation of branching process models
- Calculating the Probability of Resistance and Expected Number of Resistant Cells
- Incorporating pharmacokinetic parameters into time-dependent branching process models
- Choosing optimal schedules

Adam is currently a postdoctoral fellow with Peter Sorger at the Harvard Program in Therapeutic Science, and previously Adam completed his Ph.D in Systems Biology at Harvard University with Roy Kishony, researching the relationships between mechanisms of drug action and the evolution of antibiotic resistance.
Understanding the origin of benefit of combination cancer therapies
Developing optimal drug combinations is one of the central challenges of cancer treatment research: drug combinations are used to treat most types of cancer, and are almost exclusively responsible for cures of advanced cancers. However, historically successful combination therapies were developed empirically, and the mechanistic basis for their efficacy has been largely speculative. I will present studies of clinically successful combination therapies that identify the control of between-tumor and within-tumor heterogeneity by independently active drugs as critical contributors to the efficacy of drug combinations in human patients. Mathematical descriptions of heterogeneity in cellular or patient populations, and experimental measurements of how drug combinations address heterogeneity, lead to accurate predictions of clinical trial results across many types of cancer and types of therapies, including curative chemotherapy regimens and recent immunotherapies. These results have broad significance for the treatment of cancers, for the interpretation of clinical trials, and point to new opportunities to use combination therapies with greater precision.

About Jie Xiao
My laboratory focuses on developing novel single-molecule imaging tools in single cells to study the structure, function and dynamics of macromolecular assemblies. For example, we developed single-molecule gene expression reporting systems and chromosomal DNA conformation markers to probe the dynamics of gene regulation and transcription in bacterial cells. We also pioneered the use of superresolution imaging to probe the bacterial cell division machinery. Recently we expanded our horizons by collaborating with experts of different fields in biology to map the spatial organization of the genome and epigenetic markers of single human cells and tissues, and to develop new single-molecule based technologies for sensitive early detection of cancer markers in blood samples.
