• Manage and monitor the MIC Core and Clinical Services common IT infrastructure, including storage, backup, and networking.• Manage and monitor the MIC Clinical infrastructure, including OsiriX, PACS, and legacy RIS.• Manage and monitor research computing including the Red Hat and Bright/SGE based HPC cluster.• Oversee desktop support staff. • Assist researchers with data analysis and software toolchain development.• Study researchers’ workflows and suggest and implement improvements.At McLean, I have:• Implemented robust enterprise-grade backup systems using Bacula, Veeam, and ZFS on disk and tape backends which are capable of recovering from disk, machine, and whole-site failures via on- and off-site replication.• Implemented Zabbix-based server and process monitoring, enabling observability and real-time notification of hardware and software failures, including automated prediction of future problems using predictive models on trend data.• Designed and delivered automated analysis pipelines for fMRIPrep, allowing researchers to describe their analysis needs in a declarative YAML file, creating reproducible analysis runs over multiple participants.• Kept our research computing cluster updated with the latest imaging software and system software.• Greatly reduced hardware inventory and thus points of failure by virtualizing most services.• Managed the transfer of our local imaging storage from proprietary and non-scalable OsiriX to open-source XNAT and Orthanc, including creating reproducible Docker Compose files for all infrastructure, and implementation on TrueNAS and ProxMox backends. Implemented the ETL pipeline for the lossless transfer of existing images, metadata, and user records to the new system.

• Support clients, including many of the Fortune 50, in their use of the Ab Initio ETL software including the GDE, Co>Operating System, Control Center, Metadata Hub, and associated underlying systems.• Build software solutions on Linux, Solaris, and AIX ranging from low-level system utilities to high-performance data processing engines operating over data warehouse systems spanning tens of thousands of database tables and hundreds of petabytes of data.• Implement systems to provide data lineage traceability and provide build systems that supply reproducible reporting to end users. • Teach internal classes in the use of our technologies, and develop additional teaching materials to enhance existing classes.• Manage and help develop the internal proprietary Help system as well as its open source (nginx and Tomcat) components. • Develop and maintain internal-facing dashboards, both web-based and using custom designed hardware based on the Raspberry Pi and Arduino platforms, which help teams visualize the current support workload and notify responsible parties of new work.• Started and manage a lecture series, “Brainfood”, wherein my coworkers present interesting scientific concepts, their thesis work, or anything else they find fascinating. There have been 14 lectures to date, including topics ranging from “General Anesthesia Makes No Sense” and “Nuclear Research Reactors” to “Universal Categories and Sign Theory” and “Galaxy Cluster Mergers”.

• Developed software (Python, bash, Tcl/Tk, and C, on Linux) for FDA and CE certified robots that assist stroke and other patients with rehabilitation.• Worked with clinical staff to design research-based treatment protocols and translate these into products.• Made sure the robots followed Asimov’s First Law of Robotics by implementing multiple redundant safety systems including software and hardware based power-off systems triggering on logical, electrical, and mechanical faults, with hard real time (<1 ms) decision time requirements.• Rewrote tens of thousands of lines of legacy Tcl/Tk code in (much less) Python• Developed software in C for an Atmel microcontroller, replacing the PLC in a new product line• Developed robot mechanical dynamics simulations in Jupyter/IPython Notebook • Rewrote the central Xenomai-based real-time robot control loop to use a CANbus architecture• Redesigned software deployment mechanism, which had been based mostly on manual instructions and loose collections of shell scripts, to use modern Debian packages and containerization• Mentored junior programmers and interns
