Research Interests

My research primarily focuses on theoretical and computational advancements to support patient care in the areas of health care databases/data warehouses, federation, advanced data structures, optimization, and heuristics. It is the application of computer and data science principles to the health domain. Current research includes a new storage paradigm for heterogeneous data, federated query optimization, optimal off-target detection with IUPAC and unbounded mismatch support (bioinformatics), a rewritten JDK/JVM (Java) to improve address space and memory performance in HPC environments, and research on how best to instruct health care management-oriented students computer and information science materials.

Teaching Interests

I am interested in the technological aspects of health informatics and information management. For instance, database systems, data integrity, privacy and security, project design and management, software engineering, and pedagogy.

Datasets and Software

2017: Alliance Regional Medical Center (ARMC) Datasets. The datasets provide fabricated information for the fictional hospital Alliance Regional Medical Center (armc). All identifying information (e.g., id's, names, dates, addresses, occupations, etc.) are randomly created. Disease and medication assignments follow distributions and patterns identified in multiple healthcare datasets. Errors and outliers have been introduced to simulate those found in real healthcare environments (e.g., missing and unreasonable values). The data comes in ten varieties (from 10 to 1 million patients) and is compatible with many database management systems. Published in: Hylock, R. & Harris, S. (2017). Healthcare Database Management and HIIM Students: Challenges and Instruction Strategies - Part 2. Educational Perspectives in Health Information Management.

2016: OpenJDK9 sun.misc.Unsafe bulk-memory operation expansion. A customized version of Java (using OpenJDK9) with bulk-memory operation support. The UPC software project comes in two flavors: one based on the publicly available JVM/JDK and the other on this customized JVM/JDK. Testing indicates these enhancements significantly improve performance of sun.misc.Unsafe-enabled software, which, in this case, is the UPC software package. Published in: Hylock, R. (2016). UPC: Large-Scale Memory Efficient Java Primitive Collections. Journal of Software, 11 (3), 251-271.

2016: UPC - High Performance Memory Efficient Java Primitive Collections. Array, list, hash map, hash set, and matrix primitive collections in Java utilizing the sun.misc.Unsafe non-public API. It provides 263-1 objects (Java addresses only 231-1 spaces) with a destroy feature (a standard memory reclamation option in high performance computing (HPC) favored languages not supported by Java), and primitive collection support (also not supported by Java with the exception of arrays). Published in: Hylock, R. (2016). UPC: Large-Scale Memory Efficient Java Primitive Collections. Journal of Software, 11 (3), 251-271.

2015: Java Optimization Test Function Suite. Java Optimization Test Function Suite: One hundred two JUnit validated functions built from a consensus of 52 published sources. C/C++ version is currently under construction. The code is available via here.

2013: siSPOTR - siRNA Sequence Probability-of-Off-Targeting Reduction. Project is available as an online service hosted by the Institute for Clinical and Translational Science at the University of Iowa. As of February 2014, the code is available under the Apache License via GitHub. Published in: Boudreau, R. L., Spengler, R. M., Hylock, R. H., Kusenda, B. J., Davis, H. A., Eichmann, D. A., Davidson, B. L. (equal credit to first two authors) (2013). siSPOTR: a tool for designing highly specific and potent siRNAs for human and mouse. Nucleic Acids Research.
