NEXT SEMINAR

CLSSS is on a brief summer hiatus. Our next talk will be announced soon.

Speaker: TBD
Date: TBD
Time: TBD

Registration link will be posted when available.

A collaboration between the CRI and the Graham School Master of Science in Biomedical Informatics, the Computational Life Sciences Seminar Series (CLSSS) was launched in October 2017.

This seminar series highlights research in the fields of bioinformatics and computational life sciences, fosters collaborations, and provides a broad audience for feedback on current research. The format is flexible (e.g., standard seminars, lightning talks, etc.) and open to faculty, students, and researchers throughout the University of Chicago community.

We welcome your thoughts and feedback as we develop and grow this series.

PAST SEMINARS

May 24, 2018
Analysis and Visualization of Life Sciences Data
Presented by Teodora Szasz, Image Analysis and Data Visualization Specialist, Research Computing Center

Teodora Szasz presents a discussion of tools for visualizing, manipulating, and understanding life science research data from many image modalities, including CT, MRI, 3D Microscopy, and other techniques. Examples of analysis and visualization are presented, including segmentation, registration, and 3D reconstruction. Also discussed are use cases of deep learning for medical image analysis and different deep learning toolkits that can be used in the life sciences.

Large Scale Mental Health Measurement
Presented by Robert Gibbons, PhD, Blum-Reise Professor of Bioistatistics

Dr. Robert Gibbons discusses how innovations in adaptive testing have helped to optimize the measurement of mental health. These innovations provide an alternative to full scale survey administration that has historically been based primarily on subjective judgment and classical test theory. Computerized adaptive tests can be developed using multidimensional extensions of item response theory, estimates of items (e.g., difficulty, discrimination), and individuals (e.g., severity of depression). These tests efficiently identify suitable item subsets for each individual that allows different individuals to receive different symptom items that are targeted to their specific impairment level. The result is reduction in patient burden, elimination of clinician burden, and maximization of precision of measurement.

Development and Implementation of Anchored Multiplexed PCR NGS Assays (DNA and RNA) for Studying Somatic and Germline Variants
Presented by Erin Crowgey, PhD, Associate Director of Bioinformatics, Nemours Alfred I. DuPont Hospital for Children

Dr. Erin Crowgey presents on the diagnostic and prognostic value of studying pediatric malignancies. Chromosomal rearrangements leading to the generation of gene fusions are more common in pediatric malignancies compared to adults and possess diagnostic and prognostic value. Identification of novel gene fusions provides a means for patient stratification and the foundation for the development of targeted therapeutics. The innovations discussed include: the development of custom Next Generation Sequencing (NGS) gene panels for acute myeloid leukemia (AML), and a newborn screening assay that detects germline events in high-risk populations.

Gaining Functional Immune System Insights Through the Application of Machine Learning on Immunofluorescent Microscopy Images
Presented by Vladimir Liarski, MD, Assistant Professor of Medicine, Section of Rheumatology

A discussion with Dr. Vladimir Liarski about his work on classifying the anatomic structures of human kidney using digital images and machine learning. This research introduces a method to objectively segment and classify the these images using Python to detect glomerular and non-glomerular areas. The methodology used to train the program to classify tissue and the benefits for diagnosis and treatment are discussed.

Genomics and Microbiome, Interconnections to Health and Obesity Studies
Presented by Dr. Beatriz Penalver Bernabe, Postdoctoral Researcher, Surgery Department and Cesar Cardona, PhD Candidate, Biophysical Sciences Program

A presentation of research currently underway in Jack Gilbert’s laboratory looking at how genomics of the microbiome might be connected to health and obesity outcomes. Topics include an introductory overview of bioinformatics and DNA sequencing, as well as amplicon and metagenomics sequencing for microbial communities.

A Data Management System for X-ray Reconstruction of Moving Morphology (XROMM) Datasets: Applications for Biomechanics, Neuromechanics and Orthopedics Research
Presented by Richard Williams IV, Ph.D., Application Developer/Computational Scientist, Research Computing Center (RCC)

Explore the archiving, analysis, and publication of X-ray Reconstruction of Moving Morphology (XROMM) datasets with the XROMM Data Management (XDM) system developed by the Research Computing Center. The XDM system packages study/trial data and metadata collected at the XROMM facility, transfers the data to the Midway high performance computing cluster for analyses and long-term storage, and allows the study/trial data to be accessible via a searchable web interface, the XMA Portal. The power and promise of XROMM is demonstrated by biological research on a range of projects, including jaw kinematics during feeding in fish, pigs, and ducks, rib kinematics of breathing in lizards, limb kinematics of locomotion in humans, pigs, dogs, birds and bats, and muscle architecture dynamics in rats, turkeys, fish and birds. Join us and learn about opportunities for using the University of Chicago XROMM core facility.

Environmental and Clinical Data Commons Initiatives at UChicago: Overviews, Demos, and Opportunities
Presented by Michael Fitzsimons, PhD, Director of User Services, Center for Data Intensive Science (CDIS) and Zac Flamig, PhD, Postdoctoral Scholar, CDIS

Currently, there is a large amount of data available to researchers across a spectrum of disciplines. However, accessing and standardizing these data are a challenge and serve as an impediment to research. The University of Chicago is involved in several initiatives to build harmonized data commons that greatly improve the ability of the research community to utilize “Big Data”. The speakers will showcase some of these initiatives involving both clinical/genomics data (e.g., Genomic Data Commons) and environmental data (e.g., OCC Environmental Data Commons). Come learn about opportunities to utilize these data in your own research and/or develop software that interacts with the commons framework.
